The software is a perfect combination of the latest research results in **Photogrammetry** and **Computer Vision**, and incorporates **Deep Learning** technology for intelligent processing, which can support 3D reconstruction from oblique photography. It is also compatible with large scale traditional aerial photography, close-range photography and laser point cloud processing. The software provides highly automated processing of Aerial Triangulation, 3D reconstruction and can generate highly accurate, high quality 2D Maps ( DSM / DOM) and 3D Products (standard 3D Model, point cloud products, etc.). # Useful Concept This section introduces you to some of the basic photogrammetric knowledge required to use Get3D Mapper, as well as the relevant terminology in the software.


Oblique Photogrammetry	Oblique photogrammetry is the simultaneous acquisition of surface images from multiple different viewpoints by flying a platform with a camera on board to obtain rich surface information for the production of mapping and geographic information products.
Unmanned Aerial Vehicle (UAV)	It is an unmanned aircraft that can be equipped with different sensors and is operated by radio remote control equipment and its own program control device. The images captured by the UAV can be imported into the software for modeling.
Close to Ground Photography	Obtain high-resolution lateral texture and structural details of features using mobile phones, digital cameras, handheld gimbals, vehicle-mounted mobile surveys, stationary laser scanning, or low-altitude ring photography.
Pose File	A comprehensive representation of position (Position) and orientation (Orientation) in space, the Pose file is used to record information about the camera's position and pose when a photo is taken, recording the coordinates (x, y, z) of the position in three-dimensional space and the quaternion or rotation matrix of the camera's pose.
Exif (Exchangeable Image File Format)	EXIF is a metadata standard embedded in image files and is primarily used to store information about the image taken. This information includes shooting time, exposure settings, white balance, camera model, focal length, geographic coordinates, and so on.
Image Control Point	Image Control Points are control points measured in the field for the densification of photogrammetric and mapping control. They include plane control points (with plane coordinates only), elevation control points (with elevation only), and combined control points (with both plane coordinates and elevation).
Ground Sampling Distance(GSD)	Ground resolution, which represents the actual size of the ground (usually measured in metres) represented by one pixel (Pixel), and is related to the pixel size of the image and the height of the camera at the time of imaging, etc. GSD = (P×H)/F P represents the pixel size (in metres per pixel), H represents the camera height (in metres), and F represents the focal length of the camera (in millimetres).
Tile	3D model results are generally stored in a certain grid size, with individual grids called tiles. When large-scale 3D scene, processing the whole scene or terrain as a whole may lead to the problem of large amount of individual model data and low processing efficiency. Each tile represents a localised area that can be independently reconstructed in 3D. This chunking approach can significantly reduce the amount of data for a single processing task and can support distributed computing of tasks to improve processing speed. Tile technology also makes data transmission, storage and display more efficient.
Relative Orientation	Relative orientation refers to the work of restoring or determining the relative relationship between pairs of images at the time of photography, i.e., the work of solving the relative orientation elements of stereoscopic pairs. It is to determine the internal and external parameters of the camera by observing the positional relationship of the objects in the image in different viewpoints. The relative orientation of stereo image pairs is to restore the interrelationship of the two neighbouring image beams at the time of photography, so as to make the pairs of light rays of the same name intersect each other.
Absolute Orientation	Absolute orientation is the linking of an image to a ground coordinate system through measurements with ground control points. With the help of known ground control points, it translates, rotates, and scales the three-dimensional geometrical model, which has been relatively orientated, to incorporate it into the ground photogrammetric coordinate system. In this way, we can obtain the true position of objects on the ground.
Camera Internal Orientation	The internal orientation (or internal parameters) of a camera refers to a number of internal properties of the camera: the sensor size of the camera, the focal length of the lens, the position of the principal points in the image plane, and the lens distortion. We call a group of images a set of images with identical internal orientations. For a physical camera with all settings fixed, the internal orientation is unique. Even for two cameras of the same model with the same settings, their respective images do not constitute a single image group.
Tie Point	Tie Points are used for neighbouring models to connect image points with the same name.

Windows Server 2016
Windows Server 2019

## Graphics Card Requirements Supports NVIDIA series discrete graphics cards with at least 4GB of GPU memory, CUDA version 12.5 or newer. And NVIDIA GPU is necessary for Get3D Mapper. **The software CANNOT support AMD GPU for 3D modeling.** How to check NVIDIA graphics card driver version and CUDA version:

## Hardware Recommendation * Operating System: Windows 10/11 (64 bit) * RAM: 64GB * GPU: NVIDIA GeForce RTX 30 series or Higher * VRAM: 8GB * CPU Intel K-series CPU or AMD CPU with high base frequency # Data Formats This chapter introduces you to the input data formats and output result formats supported by Get3D mapper. ## Data Input **Image Formats:** TIFF, JPEG,JPG **Video Formats:** MP4, WMV, AVI, MOV **Point Cloud File Formats:** LAS, PTX, PTS, E57 **Pose File Formats:** TXT, CSV **Boundary File Format:** KML **Block File Formats:** XML, XBIN ## Data Output ### 3D Model The data formats supported by Get3D Mapper for creating 3D models include OBJ format and OSGB format. Both of the following data formats are supported to be opened in Get3D Viewer software. **①　OBJ (Wavefront OBJect):** OBJ format is a file format for representing 3D geometric objects. It contains information that describes the geometry of a 3D object, and its file consists of polygonal faces that are further defined by elements such as vertices, normals, curves, texture maps, and surfaces etc. An OBJ file is a vector file that is scalable and has no maximum file size limit. Due to its simplicity and readability, it has become a widely used format for exchanging 3D models. **②　OSGB (Open Scene Graph Binary):** The OSGB format is a binary file format in the framework of OpenSceneGraph (OSG), an open source, cross-platform, high-performance 3D graphics toolkit, and OSGB is the file format it uses to store and load 3D models and associated material, texture, and geometry data. The OSGB format uses a binary format and uses compression algorithms and data structure optimization to reduce file size and improve loading performance. This makes OSGB format perform well when dealing with large 3D models and complex scenes, making it an ideal choice for storing and representing 3D scene graphics data. Overall, OBJ format is mainly used to represent the geometry and texture information of 3D models, while OSGB format focuses on the efficient storage and loading of 3D models, which is especially advantageous when dealing with large and complex scenes. When loading 3D models with Get3D Viewer, it is recommended to use OSGB format to preview the model faster. ### Point Cloud Get3D Mapper supports the generation of 3D point cloud data converted from 3D models or dense matches in \*.las, \*.txt, \*.asc, and \*.e57 formats. **①　.las format (Lidar Aerial Survey) ：** The .las format is a commonly used point cloud data format developed by the U.S. Geographic Survey (USGS) and U.S. partners. It is primarily used to store point cloud data acquired by LiDAR scanners, including geometric information (e.g., coordinates, intensities, etc.) as well as other metadata (e.g., scanning parameters, classifications, etc.) for the point cloud.The LAS file is saved in a binary format consisting of a file header that contains the metadata, and a series of point records that contain information specific to each point. **②　 .txt Format (Text File)：** The .txt format is a simple representation of point cloud data, which saves the point cloud data as a plain text file. In this format, each line usually represents the location and color information of a point, making the data easy to read and process, but may not be suitable for storing large or complex point cloud data. **③　 .asc format (ASCII) .asc format, or ASCII format：** is a text file format. In this format, point cloud data is stored as visual text.The ASC model format was developed by Autodesk to make it easier to exchange 3D data between various 3D modeling software. It makes it simple to transfer and share data between different software platforms. **④　.e57 Format:** The E57 format is an open-source, compact and vendor-neutral format developed by ASTM International's 3D Imaging Data Committee. It uses a combination of binary and XML formats to store data such as that acquired by laser scanners, radar (LADAR), and optical rangefinder cameras (Flash LADAR) and LIDAR images.The content of E57 files is encoded in a hierarchical tree structure using an optimized subset of XML, which allows for the efficient storage of large amounts of binary data, making it ideally suited for the exchange of 3D imaging data. . Each of these formats has its own features and advantages in point cloud data processing, storage and exchange, and users can choose the appropriate format for their specific needs. ### 2D Data Mapper supports the generation of planar 2D topographic maps including DOM and DSM. **①　DOM (Digital Orthophoto Map):** It is the image data generated by using the digital elevation model on the scanned and processed digitized aerial film/remote sensing image (monochrome/color), correcting the projection difference pixel by pixel, and then cropping the image data according to the image mosaic according to the range of the image format.The principle of DOM production is to apply the professional geographic information remote sensing software to the original remote image after radiometric correction and geometric correction according to its characteristics. The principle of DOM production is to apply professional geographic information remote sensing software to the original remote sensing image after radiometric correction and geometric correction to eliminate all kinds of aberrations and displacement errors, and finally get the satellite remote sensing digital orthophoto maps that contain geographic information and various topics.DOM has the image with a certain geometric accuracy. DOM has a certain geometric accuracy, complete and full vegetation information, clear and uniform overall color tone, and moderate contrast. **②　DSM (Digital Surface Model)：** DSM is a digital model that represents the elevation information of the ground surface and the objects above it (e.g. buildings, trees, utility poles, etc.). It includes the elevation data of the ground surface and these obstacles, so it can more realistically reflect the shape of the ground surface.DSM can be used to produce 3D models, remote sensing analysis and many other applications. # Getting Started This section will guide you on how to use Get3D Mapper. # Newbie Guide Here we take a piece of data as an example to show you the whole process from images to model. ## 1 Download & Installation Login to the official website [www.get3d.ai](https://www.get3d.ai/), go to the download page to download the software executable program Get3D Mapper.exe, as well as the demo data.

# Edit Control Points This chapter introduces how to edit control points and complete the absolute orientation (AT). If the product generated by only inputting the photo positioning data does not meet the absolute accuracy requirement, control points should be added after the relative orientation to achieve absolute orientation and improve the absolute accuracy of the product. ## Working Interface Click **Edit GCP** to open the control point editing interface, as shown in the figure below:

The interface is divided into four parts: Control Point Information, Marking Point Information, View Panel and Photos Preview Panel The control point information bar displays the point information of the imported control point, and the marking point information bar displays the marking point information of each control point. The table header information is shown in the table, as shown below.

The view panel includes the Block View, 3D View, and Control Points Record. Block View displays a 2D view of the photos and control points within the block. It is primarily used for selecting, locking, and unlocking control points.

3D View displays the spatial positions of control points, point clouds, and photos.

Control Points Record shows the point records collected in the field, which are used to determine the actual location corresponding to the marked points. Users can refer to the point record to perform marking operations.

Photos preview panel shows photos to be marked and marking tools.

## Workflow ### **Import Control Points** Click **Import**, select the spatial reference corresponding to the control point file, select the separator, set the name, X, Y, Z, and click **OK** to import the control points.

### **Mark GCPs** Get3D Mapper supports manual marking points and intelligent marking points. **Manual Marking:** 1\) Select Control Points: In the Control Point Information Panel or Block View, select the control point to mark. Photos containing the selected control point will appear in the Photo Preview Panel. By default, photos with the point centered are displayed first, filling the panel in a tiled layout. 2\) Adjust Photo Display: The number of photos displayed per page can be adjusted. For example, if 4 photos are set per page, they will be displayed in an appropriate size. 3\) Mark Control Points: Photo names are highlighted with a yellow border. Selected photos are marked with a blue border. Hold the **Shift** key and **left-click** to mark the point. The marking position is confirmed based on field data collection. After marking, the photo name changes to a green border, and marking details appear in the Marking Information Panel. Once two photos are marked, a red prediction box will appear in subsequent photos, guiding the marking process. Press **D** to switch to the next page. {% hint style="warning" %} For optimal accuracy, it is recommended to mark approximately **30** photos per control point. {% endhint %}

**Intelligent Marking:** 1\) Initial Marking: Mark two photos manually for the control point. 2\) Intelligent Recognition: Click **Intelligent Recognition**, and the software predicts the corresponding positions in other photos. Photos with successful predictions are marked with a green border. Those without predictions remain with a yellow border and require manual marking.

3\) Check and Confirm: Verify the results on the current page. Adjust positions as needed. Click **Confirm Position** to save the markings to the Marking Information Panel. After confirming positions, the predicted points will change to red.

4\) Repeat for Remaining Photos: Navigate to the next page and repeat the steps until the required number of photos is marked with satisfactory precision. Some of the common shortcuts for Mark GCPs is shown:

### **Save Marking Results** After completing the marking, close the marking panel and save the edits to the block file. ### Submit AT After editing control points, click **Submit AT** and submit the absolute orientation. After AT processing( absolute orientation), continue submitting 3D reconstruction according to the workflow.

## AT Constraint **Usage:**\ For AT results generated from non-georeferenced data (relative orientation), a new *Constraints* tool is available under the Edit Control Points module.\ This allows you to add geometric or spatial constraints by linking control points to improve accuracy, correct deviations, or ensure geometric consistency.\ Create tie points by manually marking the same feature on multiple photos. **Steps:** 1. Mark at least 2 tie points. 2. Click *Add Constraints* to open the Constraints interface.

3. Select the constraint type.

Supported types: * **Scale Constraint:** Define the distance between two tie points to correct the model scale (e.g., building width, paint mark spacing).

* **Planar Constraint:** Force three tie points to lie on the same plane and align with a chosen coordinate axis plane (e.g., level ground or vertical wall).

* **Orientation Constraint:** Align the direction between two connection points parallel to a specified axis.

4. Set parameters, and click *Apply* to preview. Click *Reset* to revert to the original AT result. When closing, you will be prompted *“Save AT?”* Click *Yes* to apply the constraint to the block, or *No* to discard changes. # Edit Control Points\_V7.1.5 This chapter introduces how to edit control points and complete the absolute orientation (AT). If the product generated by only inputting the photo positioning data does not meet the absolute accuracy requirement, control points should be added after the relative orientation to achieve absolute orientation and improve the absolute accuracy of the product. ## Working Interface Click **Edit GCP** to open the control point editing interface, as shown in the figure below:

File samples such as the figure below, including the point cloud name, x, y, z arrangement, separated by a space in the middle:

If there is no station center coordinates, the software can automatically calculate, uncheck the Define station center. **4) Apply point cloud** After importing point cloud, click **OK** to generate a new block.

### Process Point Cloud In the point cloud block, navigate to the **Point Cloud** panel and click **Process** to cut the point cloud.

After processing, you can view and check the point cloud in the 3D view. If point cloud checked, then continue create a new 3D reconstruction according to the workflow. ## Point Cloud-Image Fusion Modeling Get3D Mapper supports importing laser point cloud data and fusing it with image data for modeling. Multi-source data fusion modeling can solve the texture distortion, feature voids and other defects in the 3D modeling process. Image data is first imported for aerial triangulation (Relative Orientation). For data containing control points, Absolute Orientation should be completed before importing the laser data for fusion modeling. After AT, open the Point Cloud panel, select the point cloud type, and add the data (e.g., mobile LiDAR).

Imports laser data: The laser data consists of .las point cloud files, and .txt point cloud trajectory line files. Click **Add Mobile Point Cloud**, select the correct coordinate system, import the point cloud file in ".las" format, and the trajectory line file in ".txt" format.

**Note: The correct coordinate system should be selected for both files.** Where the trajectory line file needs to correspond to: Time, X, Y, Z

Click **OK** and the software automatically matches the point cloud data with the track line. The two correspond to each other and the submission is successful.

Click **Process** in Point Cloud Process to slice the tiles. Once you have finished slicing the tiles, you can view both the point cloud trace lines and the image photo shelf in the 3D view.

Right click to submit Reconstruction for multi-source data fusion modeling.

Tutorial video: # AT Setting Instruction **Objective of Aerial Triangulation:** **Aerial Triangulation** (AT) aims to use the camera's imaging model to recover the camera's position and orientation during capture. **Relative Orientation** utilizes the camera's initial internal orientation elements and the relationship between correspondence points to recover the camera’s position and orientation in the relative coordinate system, along with camera’s internal parameters, distortion, and object space point coordinate. **Absolute Orientation** converts the relative local coordinate system into the absolute world coordinate system using results from the relative orientation and ground control points. ## 1 Aerial Triangulation Setting Interface

### 1.1 Preset **Relative Orientation:** Input photos (POS optional), recover the photo's position and orientation, and generate a sparse point cloud. **Absolute Orientation:** Add control points to the relative AT results, perform absolute orientation, and improve the absolute accuracy of AT. **Custom:** Custom AT settings for specific AT scenarios. **More:** Additional AT settings. The interface simplifies default operations and opens up more AT parameters, allowing users to adjust settings to better suit the current scenario when processing data.

Both **Bundle Constraint** and **Positioning Method** can be selected simultaneously. The settings in the Positioning Method are used for rigid registration, while the settings in the Bundle Constraint are used for constraint adjustment. ### 1.2 Split Setting #### **1.2.1 Relative Orientation Split Setting**

**Auto Split** and **Manual Split** processing in the relative AT bundle phase utilizes a multi-machine parallel processing strategy, improving the computational efficiency when using cluster for large-scale AT. For cases with more than 8,000 photos, it is recommended to divide into sub-blocks. **Auto Split:** Each photo has position information. Photos acquired along regular flight lines are automatically divided into sub-blocks based on the set number of photos per sub-block. **Manual Split:** Used when some POS data is missing or unavailable, dividing photos into sub-blocks based on photo groups. **No Split:** Recommended when the total photo count is less than 8,000. The AT process involves moving from one stage to the next after completing the previous task. Multi-task stages can run in parallel on multiple machines, while single-task stages are processed on a single machine. (It is normal for some engines waiting during the AT process.)

#### **1.2.2 Absolute Orientation Split Setting**

**Auto Split** processing in the absolute AT bundle phase utilizes a multi-machine parallel processing strategy, improving the computational efficiency when using cluster for large-scale AT. For cases with more than 50,000 photos, it is recommended to divide into sub-blocks. **Auto Split:** Significantly improves Absolute AT speed. If the number of control points is less than 10, it is not recommended to split block. The default setting of 50,000 images per block is recommended. Setting it too small may result in sub-blocks with no control points. **No Split:** A single task is generated and can only be processed on one machine. The AT process involves moving from one stage to the next after completing the previous task. Multi-task stages can run in parallel on multiple machines, while single-task stages are processed on a single machine. (It is normal for some engines waiting during the AT process.)

### **1.3 Efficiency Optimization** It is recommended to select Efficiency Optimization for oblique image data. Deselecting Efficiency Optimization requires more memory and longer computation time. A computer with 64GB of memory can process up to 100,000 images. ## 2 Relative Orientation ### 2.1 Oblique Image For oblique data, it is recommended to submit with the default parameters. For the city scene, it's recommended to select Efficiency Optimization

### 2.2 Orthophoto #### 2.2.3 General Orthophoto Image Recommended parameters for general orthophoto scenes. * [ ] Efficiency Optimize Image Paris Filter Level--**Medium** * [x] Pose Metadata {% hint style="info" %} It is recommended to use for high-accuracy GPS and fill in the camera accuracy. Low-accuracy GPS as bundle constraint input will affect the overall accuracy of aerial triangulation. {% endhint %}

## 4 AT Optimization In the project list, right-click on the processed block to open the AT optimization interface.

### 4.1 Secondary AT Optimization AT efficiency decreases, but relative accuracy can be improved, effectively enhancing model quality. The data processing flow is as follows: it can be selected directly during the relative orientation stage or applied based on the relative orientation results.

1\. Select the AT Optimization settings when submitting the relative orientation.

2\. AT Optimization settings for relative orientation results.

Case: If the scene contains a large number of urban buildings, it is recommended to select this option in the relative orientation stage. If structural issues are found in the modeling results, as shown in the screenshot below, AT can be optimized through secondary submission.

### 4.2 Relative Orientation Seam Optimization After merging multiple blocks with completed relative orientation, apply seam optimization to reduce the AT layering phenomenon between blocks.\ Parameter settings are divided into two cases.

1\. Multiple AT blocks roughly aligned When POS is input for relative orientation, it can be considered roughly aligned. If absolute orientation has been applied, it can also be considered roughly aligned.

2\. Multiple AT blocks not aligned When POS is not input for relative orientation and no absolute orientation has been applied.

### 4.3 Absolute Orientation Seam Optimization Merge multiple blocks with completed absolute orientation, then perform this operation to reduce seam layering. The data processing flow is as follows: Perform absolute orientation, merge AT blocks, and submit absolute orientation seam optimization.

AT setting is as follows:

Case: Considering the modeling scenario of multi-period data production, the whole survey area is divided into several blocks. After relative orientation respectively, it is a safe and reliable way to connect the edges of AT blocks through control points. However, the collection of control points is affected by various factors, leading to situations where control points cannot be collected between AT blocks. In addition, some control points may be obstructed and unusable during the point marking process. Photos at the edges of the AT, with lower overlap and weaker constraints, have a higher probability of flying out. The above three factors will cause layering problems in the model when merging reconstruction, due to insufficient common control point constraints between blocks. The image below shows the Get3D Mapper Data Manage interface, with different colors indicating different AT blocks.

The left image shows before optimization, and the right image shows after optimization.

### 4.4 Optimize by Tie Points This optimization targets small-scale layering issues that automated AT cannot resolve. By adding tie points in the layered area and marking as many visible photos as possible. If the RMS reprojection error exceeds 3 pixels or the reprojection error(relative) of some photos exceeds 5 pixels, the AT relative accuracy in that area is abnormal, leading to structural layering in the model. This operation helps assess AT relative accuracy.\ The processing flow is as follows:

Select Optimize by Tie Control Points, and the remaining parameters can be submitted with defaults.

After adding the tie points, use these points to optimize AT. The left image shows before optimization, and the right image shows after optimization.

## 5 Common AT Problems ### 5.1 Camera Intrinsic Parameters #### 5.1.1 Camera Intrinsic Parameters Inconsistency The software displays a warning about inconsistent camera intrinsic parameters when the parameters for a photo group do not match the parameters acquired by the software. There are two solutions: Solution 1: Organize the photos by resolution. Solution 2: Re-import the photos, selecting the Add Ground Photos. #### 5.1.2 Focal Length Inconsistency In Get3D Mapper, all photos in a group should use the same set of camera intrinsics. When importing photos, group them by folder. During data collection, if different devices or focal lengths are used, or if automatic photo rotation occurs, make sure to manually place photos with different parameters in separate folders. ### 5.2 Shadow Changes Significant shadow variations caused by lighting changes during aerial photography can lead to large amounts of photo loss in AT, especially when flights are captured in the morning and afternoon. If all photos in one flight are lost at the seam between two flights, you can copy the relative orientation AT results, retain only the vertical images, and check the seam areas between the two flights. Case: Pink and bright green represent two different flights. In the following images, the tenth flight line from the bottom (highlighted in the red box) has no photos in the net.

The following image shows adjacent original photos with significant shadow variation, where the overlapping areas appear completely different on the photos.

Solution: Office Work Solution: Perform separate AT processing for the upper and lower sections, then use control points to merge the two AT blocks. Field Work Solution: Re-fly and re-collect data to resolve the issue. Field Work Recommendations: Photo loss in AT processing is caused by issues during data collection. When collecting data in the field, try to avoid collecting the data of neighboring flights separately in the morning and afternoon of the same day, especially on sunny days with large light difference. # Software Overview This section will provide a detailed introduction to the interface and operation of Get3D Mapper. Get3D Mapper software contains two modules: Get3D Mapper (UI for user to operate) and Get3D Engine runs at background (algorithms for automatic modeling). # Get3D Engine Get3D Engine is a work module, running in the background processing tasks, can be online cluster processing jobs. ## 1 Principles of Engine Get3D Engine features a monitoring function for quickly checking engine status, utilization, and modifying settings. Users can adjust configurations such as the "job queue directory," "cache directory," "engine capabilities," and control the engine with "start/stop" options. * **Job Queue Directory:** Defines the job path of the current project, the jobs submitted by the current project are stored under this path, waiting for the engine to accept the processing. * **Cache Directory:** Stores temporary files during job processing, the path needs to be set to the local disk. In the Get3D Mapper main interface, the **Job Queue Directory** is used to store submitted jobs. The Get3D Engine retrieves jobs submitted by Get3D Mapper from the **Job Queue Directory**. The engine reads job information (e.g., AT\_job/Reconstruction\_job), processes the jobs, and outputs the results.

## 2 Engine Monitoring Panel The Engine Monitoring Panel at the bottom of Get3D Mapper displays the job queue and engine status.

# Project Tree This section provides overview of the interface based on the project tree and workflow. Get3D Mapper is the main user interface, the software project is a tree-like structure, which contains multiple blocks under the project. Different reconstruction frameworks can be created under the blocks according to the requirements. And multiple different types of product results can be submitted under the reconstruction frameworks.

## 1 Data Manage

### 1.1 Import Data 1. **Add Images** Get3D Mapper supports importing aerial photos and ground photos, you can organize your data according to the **file specification**, and choose to import as needed according to the actual scene.

After importing the data, the images need to be further positioned to restore their pose. Get3D Mapper supports positioning methods such as EXIF (Exchangeable Image File Format) data and pose files.

Import Photos and Pose Setting Inter face Overview

**EXIF Positioning** **1) Add photos** Select the root directory of the file to import all the photos under the folder.

**2) Read Exif location** Check the Exif information column, select the "exist" photo group, right click to open the menu bar, click **Read Exif** button.

**3) Query**

**4) Progress bar**

**5) Positioning completion** After the positioning is completed, "0/2250" is switched to "2250/2250", i.e. each photo in the photo group has positioning information corresponding to it.

**Pose File Positioning** **1) Add photos**

**2) Automatic matching of photo groups and pose files** * a) Automatic Matching Pose files are stored in the way shown in the following figure, Pose file name contains keywords such as POS; GPS; RTK; PPK, etc. After importing photos, the photo group will automatically correspond to the pose file. Tip: Pose file does not contain (POS; GPS; RTK; PPK) keywords, you can set the keywords manually, select the photo group, right-click and use the menu bar, automatically search by keywords. * b) Manual Correspondence

**3) Selection of the Pose file** Batch select multiple groups of photos by right-clicking to open **Select Pose File** in the menu bar. **4) Define the pose format template** Set the spatial reference of the Pose, the separator, and the actual meaning of each column ("photo name, longitude, latitude, elevation" or "photo name, east coordinate, north coordinate, elevation").

**5) Apply to photo groups** After defining the template, click **Apply to Group** to select the photo group.

**6) Positioning completion** After the positioning is completed, "0/2250" is switched to "2250/2250", i.e., each photo in the photo group has positioning information corresponding to it.

2. **Add Video** Get3D Mapper supports adding videos to get the corresponding video frames and add them to the block image. In the Data Manage interface, click the **Add Video** button, set the input and output file paths, and set the start and end of the extracted video frames as well as the interval time, then you can extract the imported video frames directly.

3. **Add Mobile Scan** Get3D Mapper supports the addition of laser point cloud and track line data collected by mobile laser equipment. The software supports laser point cloud modeling alone and laser point cloud fusion modeling with photos. Support vehicle-mounted, airborne, backpack, and handheld laser point clouds.

### 1.3 Edit After adding photos and pose data, in the Data Manage view each photo is expanded according to the corresponding position (x y z), and editing operations such as selecting, truncating, framing, and deleting can be performed.

### 1.4 View The photo visualization interface in the Data Manage, in the photo group list view, you can rename, block and other operations on the positioned photo group data.

## 2 Aerial Triangulation Aerial Triangulation consists of two parts, the Relative Orientation and the Absolute Orientation. * ***Relative Orientation:*** Relative Orientation, refers to the work of restoring or determining the relative relationship of the image pairs at the time of photography, i.e. solving the work of the relative orientation elements of the stereo image pairs. It is through the observation of the image of the object in different viewpoints of the position of the relationship to determine the internal and external parameters of the camera, the relative orientation of the stereo image pairs is to restore the photography of the two neighbouring image beams of the interrelationship between the two, so that the same name of the light pairs to the intersection of the light pairs. * ***Absolute Orientation*****:** Absolute Orientation is through the measurement of the ground control points, the image and the ground coordinate system for contact. It uses the known ground control points to translate, rotate and scale the relatively orientated three-dimensional geometrical model to incorporate it into the ground photogrammetric coordinate system, and to improve the absolute accuracy of AT through the control points. ### 2.1 Aerial Triangulation Settings After the photos are imported into the software, the first step is relative orientation to recover the internal and external parameters of each photo. The second step is absolute orientation to improve the absolute accuracy of the Aerial Triangulation. **Aerial Triangulation parameters setting:**

The preset options, which contain more settings, are shown below:

For a detailed description of the AT Setting, please see the **Aerial Triangulation Setting Instruction** document.

### 2.2 View Task Details To check the detailed progress of the AT, including the time for each sub-task and the total time consumed.

### **2.3 Aerial Triangulation 3D View** The content displayed in the Aerial Triangulation 3D view includes information such as photo pose, tie points, control points, laser point cloud, and laser trajectory lines.

### **2.4 AT Report** For projects that have completed Aerial Triangulation, an Aerial Triangulation report can be generated by clicking on **View AT Report** in the block view.

For projects with large image data, the process of generating this report takes some time. The AT report mainly includes the following parts: **project overview, camera calibration, photo information, tie point information,** and **control points**.

**Project overview:** It contains the project where Aerial Triangulation is located, the running time, the number of photos, the number of control points, the number of photos entering the network, the photo ratio in net, the number of tie points, the average resolution of tie points, and the re-projection error of tie points.

**Camera calibration:** A detailed list of information on the internal and external parameters and distortion coefficients of the camera set, which are used to assess the calibration accuracy of the camera. **Photo information**: Schematic of the offset distance of the camera position from the original POS data, schematic of the re-projection error for each photo, the number of connection points observed by the camera, and the scene coverage. Corresponding connection points, re-projection error for each photo.

**Tie point information**: Observation count of tie points, re-projection error of tie points.

**Control points**: coordinates and error information of each control point. ### 2.5 AT Indicators #### 2.5.1 Rate of Calibrated Photos Rate of calibrated photos is an important indicator in AT, but not the sole criterion for evaluating AT quality. The results should be assessed based on the actual data. Here are common reasons for photos not calibrated: ① Water Surface Photo Loss Blue points in the left image show photos that weren’t calibrated. In the right image, the red box highlights the missing photos.

② Mountainous Area Photo Loss Blue points in the left image show photos at the edge of the flight area. It is too close to the ground. And the terrain is forest. All these factors may cause some photos not calibrated, which is normal and does not affect modeling within the survey area.

#### 2.5.2 Control Point Accuracy The absolute orientation in AT uses control point information to adjust camera position and orientation, improving the absolute accuracy of the AT. Check the result of absolute orientation. If the error of X/Y/Z is under 0.01m, the absolute accuracy is high. #### 2.5.3 Checkpoint Accuracy Checkpoints assess the accuracy of the AT results. By comparing checkpoint coordinates with AT results, the positional error can be calculated, providing a quantitative evaluation of the AT accuracy. The accuracy requirements of the checkpoints are based on the absolute accuracy requirements of the actual model. For example, if the required planar accuracy is better than 0.1m and the elevation accuracy is better than 0.15m, the error of the checkpoints (X/Y/Z) should meet these requirements. ## 3 Reconstruction Create a **New 3D Reconstruction** or **New 2D Reconstruction** spatial frame on Aerial Triangulation (set up spatial references, area of interest ranges, tile divisions, reconstruction memory estimates, and more settings) under which one or more products can be submitted.

### 3.1 Reconstruction Setting The 2D reconstruction setting is same with 3D reconstruction. **(1) Spatial Reference System** The spatial reference system is set to the ENU coordinate system (Local East-North-Up system) by default. Users can change it to an existing or custom-defined coordinate system. Using a consistent spatial reference ensures seamless alignment of tile boundaries in subsequent reconstruction processes. **Note:** The reconstruction coordinate system supports only projected coordinate systems, not geodetic coordinate systems. **(2) Region of Interest** There are multiple ways to set the region of interest: quickly setting the range, editing the region in the view, or importing KML boundary lines. **Quickly set the range:** **Adjust to Tie Points**: The area of interest ranges to the largest outer enclosing box that contains all tie points. **Adjust to Camera**: The area of interest ranges to the largest outer enclosing box containing all cameras. **Edit the region in the view:** Select **Edit Region**, then drag the faces of the bounding box to define the area.

**Importing KML boundary lines:** Select **Import KML**, and import the the pre-drawn KML boundary line.

**(3) Tiling**

* Split Mode: Planar grid division, 3D grid division, no division. * Tile Size: Set the tile length. There is a proper tile edge length by default (related to AT resolution, related to GSD), user can customize the tile size. * Tile Overlap: Set the overlap length of neighbouring tiles. When using tile reconstruction, in order to avoid gaps between tiles, set the width of overlap between tiles. * Origin XYZ: Set the coordinates of the origin of the tiles. * Preview in Real Time: After modifying the parameters, display the updated result in the 3D view in real time. * Discard Empty Tiles: Tiles without tie points are not reconstructed.

**(4) Save and Load** Save: save the reconstruction space frame settings, including space reference, tile division origin, tile size, tile overlap. Load: load the reconstruction space frame settings. **(5) Memory Estimation** Single tile using the maximum memory value prediction, tile reconstruction requires the size of the computer memory related to the tile size (the larger tile, the larger the computer hardware memory required), according to the computer memory to determine the size of the tile division, the prediction of too much memory will lead to the failure of the tile reconstruction. For example, if you have 64GB of computer memory, you can adjust the tile length, set the tile estimated memory to 30GB, and actually divide the largest tile. **(6) Copy Setting** Copy other reconstruction parameters under the same project contains space reference, tile division origin, tile size, and so on. ### 3.2 More Settings

More Reconstruction Settings interface allows you to set the **Point Cloud Generation**, **Mesh Generation**, **Texture Fill** and **2D Reconstruction Hole-Fill Mode** in the reconstruction step. Different preset reconstruction modes can be set in **More Setting** for different modeling scenarios: l General: The default mode is a balance between model quality and processing efficiency and is suitable for most reconstruction scenarios. * **General**: The default mode is a balance between model quality and processing efficiency and is suitable for most reconstruction scenarios. * **High Quality**: High quality mode generates more structural details, consumes more memory and time (about 4 times longer than general mode) to process the same data, and is suitable for fine modelling of small scenes. * **High Efficiency**: High-efficiency mode pursues high-efficiency modeling quality, the quality of the model will be reduced, the demand for memory and storage resources is small, and the time consumed is short, suitable for large scenes, and the geometric accuracy requirement is not high for rapid modeling scenarios. * **Define**: Users can choose suitable reconstruction parameters according to their own needs. **① Point Cloud Generation** Mainly image dense matching strategy, photo selection strategy, matching strategy, matching accuracy. **② Mesh Generation** **Topology Construction:** * 3D mesh: suitable for most model reconstruction cases. * 2D mesh: suitable for downward looking image modeling. **Mesh Simplification:** * Light: low simplification effort, denser triangular mesh, more (valid and invalid) geometric details, larger data volume. * Normal: moderate strength of simplification, with a balance of data size and (valid and invalid) geometric details. * Strong: strong simplification, sparser triangular mesh, largely filtered (valid, invalid) geometric details, smaller data size. **Mesh Optimization：** If selected, the 3D model contains more details. **Seam Optimization：** Topology optimisation of the geometry between tiles can effectively avoid gaps between tiles. **③ Texture Fill** * Automatic Interpolation: Automatically fills texture gaps using surrounding textures. * AI Repair: Utilizes AI algorithms to intelligently restore missing textures. * Solid Color: Fills missing areas with a uniform color. **④ 2D Reconstruction Hole-Fill Mode** DSM/DOM Fill Hole Mode: Adaptive fill and full fill ### 3.3 Reconstruction 3D View

* Layers show/hide: Show/hide region of interest, tile, camera, tie point, point cloud, control point. * Home: Reset the 3D view. * Camera +: increase the size of the camera in the 3D view. * Camera -: increase the size of the camera in the 3D view. * Edit Region: Manually adjust the reconstruction range in the 3D view, select and then determine the area of interest, i.e. the modeling area, by extruding and stretching the box. * Import KML: Import KML range for reconstruction range constraints, output 2D and 3D model results can be output by range line shape. * Export Tile Boundary KML: For the selected tile, export tile boundary as KML file. ## 4 Product ### 4.1 3D Reconstruction--Product Get3D Mapper can output 3D model products in OSGB and OBJ formats, 3D point cloud products in LAS, TXT, ASC and E57 formats, DOM products in TIFF and JPG formats, and DSM products in TIFF and ASC formats. Several different types of products can be submitted under the same reconstruction framework.

**① 3D model product** After the Aerial Triangulation processing is completed and the reconstruction settings are finished, you can submit the 3D model products in OSGB and OBJ formats for generation. Select the output format, texture source, texture quality, maximum texture size, and the way to adjust texture.

* **OBJ**: OBJ is a 3D model file format for model editing and browsing. The .obj file mainly contains information about the vertices, normals, texture coordinates, and faces (triangles or polygons formed by vertices) of the 3D model. The \*.mtl file defines the properties of the materials used in the model, such as colour, gloss, texture mapping, etc. The \*.jpg file is the texture coordinates of the material. \*.jpg files are texture maps. * **OSGB**: OSGB is a binary format for 3D model data, suitable for applications such as model browsing and real-time rendering.One of the features of the OSGB format is that it can support model representation with multiple Levels of Detail (LOD, Levels of Detail), which allows the system to dynamically load and display model levels of corresponding fineness according to the distance of the observer.

**Use Multiple Origins:** When submitting a product, import a multi-origin planning file. It will automatically export the different tiles by origin. **Select Tiles:** Select the tiles of interest to be generated into a 3D model or point cloud.

**② 3D point cloud product** After generating a 3D model, the model is sampled to produce a 3D point cloud product. The software interface allows you to set the point cloud product output format, point cloud source, and resolution.

**③ 2D product** After generating the 3D model, the model is sampled to generate DOM and DSM products. The software interface allows you to set the sampling distance, image dimension, DOM product format, and DSM product format.

**Select Grids:** Select the grids, which correspond to the grid divisions set up for the 3D reconstruction spatial frame. Selection method is same with selecting tiles. The view shows areas that have not been reconstructed, have been reconstructed, and have been selected.

### 4.2 2D Reconstruction--Product The software interface allows you to set the resolution, compression type, DOM product format, and DSM product format.

**Select Grids:** Select the grids, which correspond to the grid divisions set up for the 2D reconstruction spatial frame. Selection method is same with selecting tiles. The view shows areas that have not been reconstructed, have been reconstructed, and have been selected.

① Select the corresponding "Block", "Reconstruction" and "Product". ② Select the **DOM** and **DSM** of the products to be merged and set the output path. ③ Input the sample interval. ④ Set the correct coordinate system. ⑤ Click **Merge** button to start merging DOM/DSM. ### **4.2 Model Origin Setting** For 3D models in OSGB format, due to limitations on decimal precision, data with ground resolutions at the centimeter level may experience a loss of precision when the model's position in the X or Y direction exceeds 10,000 meters from the origin during reconstruction. This can lead to visual issues such as flickering surfaces in the displayed model. To address this, a model origin should be defined for every 10,000-meter grid to reduce the magnitude of model coordinate values. ① Import boundary KML/SHP.

② Set the initial origin coordinates, gird length and model origin position.

③ Model origin view.

④ Export model origin.

⑤ Import multi-origin file in product setting interface. Tiles will be exported automatically based on the defined origins.

For a large number of control points in a project, Get3D Mapper supports multiple computers to mark GCPs together to enhance work efficiency.

Get3D Mapper supports opening sub-projects on multiple computers, and the only operation that sub-projects can do is to edit control points. When the main project enters the interface of editing control points, it locks all control points by default. When the main project releases a portion of the control points, the secondary project can lock that portion of the released control points and perform Mark GCPs operations. When multiple computers have finished collaborating on the marking, click on each computer to save the control point information. Finally, the main project will update the control point information.

The specific operation is as follows: 1\) In the main project in the submit AT interface click **Edit GCP** to enter the Edit Control Points interface. **Import the control point file** and **select the correct coordinate system**. 2\) Select some control points and click **Unlock**.

3\) Open the project on another computer. When you open it, the default prompt is that the project opened here is a sub-project, and you can only edit control point operations.

4\) Enter the Edit Control Points screen, click **Update** to see the unlocked control points, and then you can Mark GCPs on the machine after locking it.

For more details on marking GCPs, refer to the section [Edit Control Points](/user-help-center/get3d-mapper/getting-started/edit-control-points) 5\) When sub-project has done marking, click **Update** and **Save**.

Update and Save Sub-Project Marking Results

6\) After completing all marking points operation, click **Update**, **Save** in the main project to exit this screen.

# Automatic Block Division This section will introduce you how to divide block automatically.

Scenario:\ For 3D models in OSGB format, due to limitations on decimal precision, data with ground resolutions at the centimeter level may experience a loss of precision when the model's position in the X or Y direction exceeds 10,000 meters from the origin during reconstruction. This can lead to visual issues such as flickering surfaces in the displayed model. To address this, a model origin should be defined for every 10,000-meter grid to reduce the magnitude of model coordinate values. Model Representation: Model Position = Model Coordinates + (x, y, z) in metadata.xml Example:

Steps: ① Import boundary KML/SHP.

② Set the initial origin coordinates, gird length and model origin position.

③ Model origin view.

④ Export model origin.

⑤ Import multi-origin file in product setting interface. Tiles will be exported automatically based on the defined origins.

#### 4.1.3 Merge DOM/DSM Added a merging tool with coordinate system conversion capabilities.

### 4.2 Enhanced Features #### 4.2.1 Edit Control Point The interface is divided into four parts: Control Point Information, Marking Point Information, View Panel and Photos Preview Panel Control Points Information:

Marking Point Information:

3D View displays the spatial positions of control points, point clouds, and photos.

Photos preview panel shows photos to be marked and marking tools.

Please refer to [Edit Control Points](/user-help-center/get3d-mapper/getting-started/edit-control-points) section to see more operation details. #### 4.2.2 Default Tile Size Prevents crashes during new reconstruction tasks by setting reasonable default values. #### 4.2.3 Project Space Reduces space usage by over 40%; total size does not exceed raw data storage. Optimizations have been implemented to reduce disk space consumption during project operations. The disk space required for projects in the Get3D Mapper 7.0 version is significantly reduced. It is recommended to reserve storage space equivalent to 1x the raw image data size.

#### 4.2.4 Export Block Improved export options for reconstruction blocks, supporting various formats (e.g., XML, XBIN).

## Aerial Triangulation (AT)

What's the difference between Relative Orientation and Absolute Orientation?

Relative Orientation utilizes the camera's initial internal orientation elements and the relationship between correspondence points to recover the camera’s position and orientation in the relative coordinate system, along with camera’s internal parameters, distortion, and object space point coordinate. Absolute Orientation converts the relative local coordinate system into the absolute world coordinate system using results from the relative orientation and ground control points.

Where can I find the report for AT result?

After AT is completed, click View AT Report to view and export the AT report, which includes total processing time, camera information, pose and tie point details, control point information, and more.

How to merge data from different blocks?

Without field GCPs: Mark several tie points in block1\_AT (within the overlap area) and use these points as control points in block2\_AT. After marking them, submit AT again for block2\_AT to generate block2\_AT\_absAT. Merge block1\_AT and block2\_AT\_absAT into a single block, then submit reconstruction for the new block. With field GCPs: Ensure there are enough control points in the overlap area, especially at the edges. Edit these control points for both block\_AT datasets. Then, submit AT again for both blocks to obtain two block\_AT\_absAT. Merge them into a single block and submit reconstruction for the new block.

Can I delete some tie points?

In the AT 3D view, you can delete tie points by selecting them with a selection box, or by importing a KML vector file to remove points.

Why does AT run on only one engine in cluster mode?

The final stage of AT merging bundle requires only one node to run.

How to reuse AT result?

Within the same project, a single AT block can be used to generate multiple reconstruction products, or the AT can be duplicated for a new reconstruction. The software also allows exporting AT results, which can be imported into a new project’s AT block for further use.

## Edit GCP

How can I use GCP in Get3D Mapper?

Using control points for absolute orientation can improve result accuracy. After relative orientation in large-scale image AT, edit the control points and then submit absolute AT. Please refer[ Edit GCP](/user-help-center/get3d-mapper/getting-started/edit-control-points) section for detailed steps.

How many times should I mark for one GCP?

For optimal accuracy, it is recommended to mark approximately 30 photos per control point.

Where can I find the accuracy information after editing GCP?

After editing the control points and completing absolute orientation, you can view control point error information in the Control Points panel within the control point editing view, or check the error details for each point in the Control Points section of the AT report.

What is the difference between DOM/DSM results in 2D reconstruction and 3D reconstruction?

In 2D reconstruction, the DSM is generated based on image AT, and the DOM is produced by orthorectifying nadir images, without generating a mesh. In 3D reconstruction, the results are generated by projection onto a mesh and can only be used after the mesh has been created.

## Cluster

Does cluster number have limitation?

There's no limit to cluster number.

How to build cluster and connect the computer?

Please refer [Cluster Computing](/user-help-center/get3d-mapper/cluster-mode/cluster-computing) section for detailed steps.

## Other

How to resume process?

Cache files for each processing stage are stored in the project directory. If the project is closed without canceling the job, the engine will continue processing tasks in the background. If both the project and engine exit unexpectedly, reopening the software and restarting the engine will resume task processing. If a job is canceled and then resubmitted, the software will reuse existing cache files and does not require reprocessing.

# Troubleshooting

Task waiting

#### 1. Check whether the engine is started. * If the engine is not started, the status will show **None**. Click **Start Local Engine** to start it.

#### 2. Check whether the **Job Queue Directory** for project and for engine are consistent. * If the engine is already started, and paths are inconsistent, the status will show **Inconsistent Path.** This means the **Job Queue Directory** for project and for engine do not match.

* Change the engine path to match the job queue path for project. You can do this in **Settings** and apply the changes.

* Or right-click the engine in the engine panel and modify job queue directory for engine.

#### 3. Check if there's Engine Capability. * If there is no **Engine Capability** shown in the engine panel, right-click and **Set Engine Capability** and select **Get3D Mapper**.

Engine path doesn't exist

1. Check whether **Get3D Engine** is installed. If not, please reinstall **Get3D Mapper**. 2. If **Get3D Engine** is already installed, locate the installation path and manually launch the engine executable.

AT failed

1. Ensure that an NVIDIA GPU is being used and check whether the CUDA version is higher than 12.5. If not, update the GPU driver to the latest version. 2. If the hardware environment is correct, check whether the data paths are valid. If a data path does not exist or the data is corrupted, this will be indicated in the error message. Corrupted data should be removed. If a path does not exist, use the **Modify Photo Directory** function to check and update the photo paths. Also check whether the paths contain special characters.\ **Note:** In cluster mode, use IP-based network paths instead of character-based paths. 3. Check whether there is sufficient free space in the cache directory. 4. Check for insufficient CPU or GPU memory. 5. Verify that the camera parameters are correct. 6. Check whether the original pose metadata is correct. The original positions can be viewed in the block’s 3D view. 7. Adjust the AT settings. For different scenarios, refer to the **AT Instruction** for recommended configurations.

Less than 90% in net

1. If the non-meshed areas are entirely water surfaces, they can be ignored. 2. If the non-meshed areas are entirely vegetation, they can be ignored. 3. If the overlap between meshed and non-meshed areas is low, adjust the parameters by increasing feature density and lowering filtering strength. 4. If lighting conditions vary significantly during data acquisition, feature points may fail to match. Such data is not suitable for processing and should be re-acquired.

3D reconstruction failed

1. Check whether there are empty tiles. 2. Insufficient system memory or GPU memory. 3. Issues with photo paths or corrupted data, or insufficient disk/storage read permissions. 4. Insufficient cache space. 5. The process was terminated unexpectedly. 6. Delete intermediate files and resubmit the task. 7. The issue may be caused by network instability, resulting in missing intermediate files during processing. Resubmit the tiles. 8. Create a new reconstruction and try a different coordinate system.

Failed in cluster

1. In a cluster environment, if failures repeatedly occur on a specific node, you can disable the engine on that node and continue processing with the remaining nodes. Check whether the storage and compute nodes can all access each other’s data. 2. For failures in a cluster environment, verify that both storage and compute nodes can mutually read the data. You can also try placing the data and project on a local machine and running the task in standalone mode to see whether it completes successfully.

## 1 Create Project After opening the software, click **Project > New** to enter the project setup interface. Set the project name and path, then select OSGB and OBJ files.

* Without OBJ data, the project can only perform OSGB color correction but cannot edit oblique data. * The OSGB data must include **data** files and **metadata.xml**. * OSGB and OBJ must have the same offset and coordinate system. * To use the AT Mapping feature, click **AT Setting**, select the AT file path and photo path, then click **OK** after setup.

## 2 Global Processing After creating the project, the software automatically opens the **OSGB View**, which provides an overview of the entire model. In this view, you can browse the model and see operation traces.

The **Delete Fragments**, **Water Fix,** and **Color Adjustment** functions apply edits to the entire model and must be performed in the **OSGB View**. Following standard workflow: 1. **Delete bottom fragments** and **repair water surfaces** after creating the project. 2. **Color adjustment** is typically done at the final stage of model editing. For more details on deleting fragments, refer to the section [Detailed Functions > Structure > Delete Fragments](/user-help-center/get3d-modelfun/getting-started/structure#id-6-delete-bottom-fragments).

For more details on water surface refinement, refer to the section [Detailed Functions > Structure > Water Fix](/user-help-center/get3d-modelfun/getting-started/structure#id-1-water-surface-refinement).

For more details on color adjustment, refer to the section [Detailed Functions > Texture > Adjust Color](/user-help-center/get3d-modelfun/getting-started/texture#id-5-adjust-color). Edited results must be viewed in the **OBJ View**. To check the edits, click **Open/Close Tile** button and select tiles in the **OSGB View**, and the software will automatically load the corresponding **OBJ View**. ## 3 Tiles Processing After completing the overall editing, edit the model's local parts by tiles in the **OBJ View**. 1\) Select one or multiple tiles open for editing.

2\) Use the structure and texture functions to modify the model's local parts. There is no strict order for using the editing tools, but typically, the sequence is to work on the structure first and then the texture.

3\) After editing, close the tile, select another area tile to continue editing, and repeat until the entire model is completed. {% hint style="warning" %} Do not open too many tiles at once, as it may cause the model to lag, affecting the operation. {% endhint %} For more details on editing functions, refer to the section [Detailed Functions > Structure](/user-help-center/get3d-modelfun/getting-started/structure) and [Detailed Functions > Texture](/user-help-center/get3d-modelfun/getting-started/texture). ## 4 Save Project The edited results are saved in the project.

#### **Water Fix Operation:** Step 1: Draw the water surface range Work in the OSGB view to define the surface scope. The surface elevation is set by the first point, which must be placed at a clear junction between the water and the waterfront. Subsequent points should be within the waterfront area. Double-click to close automatically. Detailed Operating Steps: **1) Set the first point.** Find a clear junction between the water surface and the waterfront, then left-click to place the first point. **Tip**: It's recommended to select a dam or a steep waterfront as the first input point. **2) Draw the remaining points to complete the waterfront boundary.** **Tip**: When adding more points, there is no need to outline the waterfront precisely—just ensure the shape fully encloses the water surface, as shown in the example below. **3)** **Double-click to finish.** The program will automatically calculate the possible shoreline, which will be displayed as a green line.

**4) Set water surface elevation.** If the shoreline elevation is not satisfactory, you can reselect the water surface elevation. Click the **Pick** button, then click on the desired elevation point in the view. Or manually enter the elevation value.

Step 2: Adjust the shorelines Check the view. If you notice an error in the automatic shoreline calculation, click the **"Edit"** button to adjust the boundary. **Tip:** Only need to observe the edge of the water surface. The green lines in the center of the surface do not require any editing. Detailed Operating Steps: **1) Browse and find the errors.** **2) Click "Edit" to adjust the shoreline and perform the box adjustment.** **3) Double-click to end the box drawing, and the shoreline will automatically expand outward according to the drawn purple box.**

**4) Edit the remaining incorrect shoreline.** * Click **"Undo"** to revert recent change. * Click **"Reset"** to restore all adjusted shorelines.

View Background settings usually include two effects: **Skybox** and **Pure Color**. **Skybox:** Skybox is a background effect that simulates the real-world sky environment. It usually uses six texture maps (corresponding to the top, bottom, and four sides of the sky) to create a closed three-dimensional space, giving the user a sense of reality. With the Skybox effect, the model's background will show a three-dimensional sky environment, making the model more realistic and integrated into the virtual scene. **Pure Color:** Pure Color Background is an easy and clean way to set the background. Users can select the desired background color from the color palette or enter a custom color value for precise adjustment. A solid color background highlights the model itself and avoids excessive visual distractions, allowing the user to focus more on the structure and details of the model. * **Skybox View Background Effect:** The Skybox background effect provides a more three-dimensional and realistic background for model presentations by simulating a real-world sky environment. This type of background is suitable for presentations that create a specific atmosphere or scene, such as urban planning, landscape design, etc. ![Skybox View](/files/oRJVapmqE3R52hRGcRgu) * **Pure Color View Background Effect:** When a pure color background is selected, the view will display a single-color background, which is clean and simple and can highlight the features and details of the model. The solid-color background is suitable for scenes where the model itself needs to be emphasized, such as model renderings, screenshots, or recordings. ![Pure Color View](/files/MXuIRSFzvdVIKmRCyQ0Y) ## Hide Get3D logo {% hint style="info" %} Only VIP users can choose to hide Get3D logo. {% endhint %} **Screenshot & Recording Optimization:** Hiding the logo in the lower right corner is mainly for users' convenience when taking screenshots or recording screenshots.

## Texture Mode Texture mode is essential in visualizing a 3D model by determining how the model surface is displayed. By switching the texture mode, users can choose between displaying the model as "white model" or "texture model" to meet different viewing and analysis needs. By clicking the **\[Texture Mode]** button or pressing the **\[1]** key combination, users can easily switch the display state of the Texture to achieve different viewing effects. * **White Model Display:** When the White Model Display mode is selected, the surface of the 3D model is rendered in white material, presenting clean geometry. This display mode is often used to highlight the model's geometry and reduce the visual interference of texture details, allowing users to focus more on the model's overall shape and spatial relationships. ![White Model](/files/rvAZuZiLJHAHrpoYKbaP) * **Texture Model Display:** The Texture Model Display applies realistic texture maps to the model's surface to make it look more realistic and detailed. These texture maps can include color, material, lighting, and other information, which can simulate the texture, gloss, and other visual effects on the model's surface. The color film display mode is usually used in scenes that require a more realistic rendering of the model's details and appearance. ![Texure Model](/files/aOH6vYqlqrsbB8uy16Ge) ## Wireframe Mode Wireframe mode is a display mode commonly used in 3D model viewing, which allows users to view the internal structure and outline of the model by controlling the appearance of the wireframe. By clicking the **\[Wireframe Mode]** button or pressing the **\[2]** key combination, users can easily switch the display state of the wireframe to achieve different viewing effects. * **Model + Wireframe:** When the user presses the **\[2]** shortcut key or clicks the "Wireframe Mode" button for the first time, the model is displayed in solid form with a black wireframe superimposed on it. This mode helps the user see the model's outline and structure, especially when the model details are complex or difficult to distinguish. ![Model + Wireframe](/files/gLe4EY0HLeogIm8c0T4q) * **Wireframe Only:** When the user presses the hotkey "2" a second time, the model is hidden, and only the white wireframe is displayed. This display mode allows the user to focus on the lines and structure of the model, which is helpful for spatial analysis and design review. ![Wireframe Only](/files/Ra7pLIGkGKKrmK3G4sJB) * **Hide Wireframe, Show Model Only:** When the user presses **\[2]** for the third time, the wireframe is hidden, and only the model solid is displayed. This allows the user to see the final rendering of the model without the distraction of the wireframe. ## Clip View This feature allows the user to crop the entire contents of a view by drawing a crop box. This allows the user to focus more on the area of interest while optimizing the view's display. The following is a specific description of this feature and its guidelines. ![Clip View](/files/G2WaDuKL6irpSHQ3y6M7) * Drawing the Crop Box: When the \[Draw the cut Box] logo is highlighted, it means that the crop box is currently in the Draw Crop Box state. Left-click in the view to identify the three points on the bottom of the crop box. Move the mouse up and down to set the height of the box. * Editing the Crop Box: Move the mouse over the crop area to be adjusted, and the crop area will be highlighted. Press the left mouse button and drag the cropping area to edit the box. Click the Reset button to return the box to its original state. Click the Delete button to delete the current box. * Result Display: After cropping, the view will only show the contents of the cropping box. # Views Menu The views menu is used to display and adjust the model's orientation and movement mode ![Views Menu](/files/kDoAb18Nkmivz5VbspHF) ## Basic View Basic views are several views commonly used in 3D model viewing, they show the model from different directions and help the user to fully understand all aspects of the model. ![Basic Views](/files/ib7962oJoddTDo0lGLPR) * **Top view:** looking vertically down from the top of the model, showing the top surface and details of the model. * **Bottom View:** Looking vertically up from the bottom of the model, showing the bottom surface and bottom details of the model. * **Left View:** Looking vertically to the right from the left side of the model, showing the left surface and left details of the model. * **Right View:** Looking vertically from the right side of the model to the left, showing the right side face and right side details of the model. * **Front View:** Looking vertically back from the front of the model, showing the front surface and front details of the model. * **Back View:** Looking vertically forward from the rear of the model to show the rear side and rear details of the model. ## Reset View In the 3D Model Viewer, users often rotate, pan, or zoom the view to view the model from different angles and distances. However, there are times when the user may want to return the view to its original state, i.e., how it looked when it was first loaded, in order to start over or make comparisons. For this reason, the Reset View function is very useful. * **View manipulation:** The user can change the display state of the view by performing operations such as dragging, rotating, or zooming. These operations allow the user to view the model from any angle and distance for different viewing needs. * **Reset View:** If the user needs to return to the initial view state, they can click the Reset View button. This will immediately reset the view to the state it was in when it was first loaded, including the viewing angle, zoom ratio, and pan position. ## Full Screen Full screen mode is a feature that expands the 3D model viewer to fill the entire screen for an immersive experience. When the user clicks the Full Screen button, the viewer occupies the entire screen, eliminating all other windows or interfaces and allowing the user to focus more on the model. ![Full Screen](/files/hDdffoKdt5e6XKc9OQev) * **Enter Full Screen Mode:** When the user clicks the Full Screen button, the 3D model viewer will expand to fill the entire screen, hiding all other windows and interfaces. This provides a distraction-free environment, allowing the user to focus more on viewing and editing the model. * **Exit Full Screen Mode:** The user can exit full screen mode by pressing the **Esc** key. This returns the 3D Model Viewer to its original size and redisplays other windows and interfaces. ## Dua-View The Dual-View Comparison feature provides a convenient way to view and compare 3D models. It allows the user to visualize, compare and analyze the same area reconstructed at different times or by different software by displaying it on two monitors at the same time. To use this feature, the user must prepare two sets of model data. ![Dua-View Comparison](/files/QBGQ9Jz3cAqSX0OIzcZK) * **Dual Screen Load:** First, users need to load the first set of model data by following the method of opening the local model file or folder, or opening the cloud model. Then, by clicking the Dual-View Compare function button, the view will switch to dual screen mode and prompt the user to load the second set of model data. * **Browse and Compare Models:** In dual-view mode, users can browse and compare the differences between two models by long pressing the left mouse button to rotate, long pressing the scroll wheel to pan, and long pressing the right mouse button to zoom. * **Exit Dual-View Mode:** Users can exit the dual-view mode at any time and return to the single-screen display by clicking the dual-view compare button again. * **Model Linking:** This feature allows users to rotate, pan, zoom in and out on two models simultaneously. When the Model Linkage switch is turned on, the left and right screen view changes are synchronized; clicking the space bar resets the left and right screen views simultaneously. * **Restore View:** This function is used to reset the model to the initial state after successful loading. No matter how the model is rotated, panned or zoomed, clicking the Restore View button will restore the left and right screen views to the original state at the same time. * **Show/Hide:** Users can choose to show or hide a model in the model list. * **Delete:** Users can delete unneeded models from the list. * **Other Functions:** Includes functions such as rename model, zoom to this layer, open model folder, and reload model. ## Lock Vertical Axis Vertical axis locking is an important feature in 3D model viewing and manipulation that is used to control the tilt angle of the model in the vertical direction. This feature is particularly useful for maintaining model orientation and avoiding confusion, especially when working with models that have a clear up and down orientation. * **180° Flip:** When the vertical axis lock function is on, the user can flip the model 180 degrees in the vertical direction. This means that the model can only be switched between up and down without more complex rotations. * **360°(Unlimited) Flip:** When the vertical axis lock is off, the model can be flipped 360 degrees without restriction. This means that the user can rotate the model from any angle without any directional restrictions. ## Lock Elevation This function is a commonly used tool in 3D model viewing and manipulation that allows the user to move the model horizontally while keeping the height of the model constant, thus changing the viewing position of the model. * **Lock Elevation On:** The elevation (i.e., vertical position) of the model remains constant as you drag the 3D model. This means that the vertical position of the model will not change no matter how much the user pans the model. * **Lock Elevation Off:** Allows the user to freely move the model in the horizontal direction. The user can change the view position of the model by dragging the model. ## Lock Angle Viewpoint locking is a feature commonly used in 3D model viewing and editing that allows the user to lock the angle between the direction of the line of sight and the horizontal grid of the model to a specific value, usually any value between 0° and 90°. This feature is useful when precise viewing or editing of the model is required. ![Lock Angle](/files/u5Oz23qfsrVTakgLeoK7) * When the **Lock Angle** function is selected, the angle between the direction of the user's line of sight and the horizontal grid will remain between the set value and 90° when the user rotates or flips the model. This means that no matter how the model is rotated, the user's line of sight will remain at a constant angle, which facilitates accurate editing and viewing. * When the **Lock Angle** is not selected, there is no angle restriction when the user flips or rotates the model. This means that the direction of view is free to change as the model is rotated, and the user can freely adjust the viewing angle as needed. ## Lock Rotation * **Lock Rotation On**: The model can only be panned and cannot be rotated. * **Lock Rotation Off**: The model can only be panned and rotated freely. # Analysis Menu The analysis menu allows user to check, meature, and annotate models. ![Analysis Menu](/files/AbBXPW4IO8g63obcAl5k) ## Model Accuracy Check This feature plays a critical role in 3D GIS applications by allowing users to verify the model's accuracy using external checkpoints and generate detailed accuracy reports. This feature is handy in scenarios where model accuracy must be ensured, such as urban planning, terrain analysis, architectural design, and other fields. 1. Launch the accuracy check function When you click the **\[Precision Check]** button, the system will display the corresponding interface. In this interface, users can load the checkpoint file and select the corresponding points on the model. ![Model Accuracy Check](/files/4cbIdljAlfdvlMREi4LC) 2. Load Checkpoint File When you click the **Browse** button behind the checkpoint file, the system will pop up the file selection dialog box. The user must select the existing checkpoint file. The file should meet the specific format requirements: each column represents the point number, east coordinates, north coordinates, and elevation, and spaces separate the columns. ![Load Checkpoint File](/files/UTiJZO30Gl5liLwKluQ5) 3. Selecting and Viewing Checkpoints After loading the checkpoint file, each checkpoint's point number and coordinate information are displayed in the list. Users can double-click a checkpoint in the list to make the model jump to the corresponding position and mark the point's position in the external coordinates with a green flag. ![Selecting and Viewing Checkpoints](/files/pAo9RHctGach5y9wQ7yR) 4. Measuring Model Coordinates Click on the model to get the checkpoint's model coordinates. These coordinates are recorded in a list, and the clicked position is marked with a yellow flag. The system automatically calculates the difference between the field and model coordinates. ![Measuring Model Coordinates](/files/kcUTrWwDWhgBxCnsGfQz) 5. Calculate the Error After measuring the model coordinates of all checkpoints, the system calculates each point's plane and elevation errors and automatically counts the median errors of plane and elevation. ![Calculate the Error](/files/O0rD63X9hVhnH7BBe0DQ) 6. Filter Checkpoints Users can enter keywords in the query box and click the search button. The list will automatically filter out checkpoints unrelated to the keywords, making it convenient for users to quickly find points of interest. 7. Export Checkpoint Report Click the **\[Export]** button; users can choose to export the report in **.csv** or **.pdf** format. After setting the file name of the exported report, click **\[Save]**. In addition, users can also save the report as a dvp file to record the inspected points and points to be inspected so that it is convenient to complete the taskmultiple times or to resume the work after accidentally exiting the program. ![Export Checkpoint Report](/files/Njms5xXqFlKjYAkS76Xp) ## Add Label The label plays a crucial role in 3D GIS and is widely used in many industries and fields, such as emergency response, land surveying, planning, and design. Label technology provides users with an intuitive and accurate means of geographic information labeling through the form of points, lines, areas, and shorelines. Users can select the label to edit, including moving the point labels' position and adding or deleting the nodes of line or surface labels. The optimized line and area labels display information more clearly, and the area labels show a semi-transparent effect (60% transparency) in the initial state, which makes the labels' information more coordinated with other geographic elements. Supports showing and hiding label names, including single labels, all labels, and batch labels. The label panel provides drag-and-drop, docking, resize, and collapse/expand functions, which makes it convenient for users to adjust the interface layout according to their needs. ### Point Label A point label is used to annotate individual objects and can also be combined with line and area labels. Users can use the **\[F1]** shortcut to access the point label too quickly. Point label attribute icons support six colors and 27 styles, and users can change the name and add rich description information according to their needs. ![Point Label](/files/EPrjkN7gkGJaaFX18KdS) ### Line Label A line label usually takes the form of a folded line, which is used to express geographic elements such as roads, rivers, and so on. Users can quickly use the line label tool by pressing the **\[F2]** key. Linelabel supports different color and transparency settings, and you can add names and descriptions. The line length measurements are below the property bar. ![Line Label](/files/B2u61DiG8EWjnbtitnoX) ### NGons Label NGons label is used to express specific NGons, such as construction NGons, disaster NGons, etc. Users can quickly use the face label tool by pressing the **\[F3]** key. Area labels also support color and transparency settings and can be given a name and description. Measurement results are below the property bar. ![NGons Label](/files/dUxj70sfhdveaTgq7OVR) ### **Shoreline Label** Unlike NGons Label, Shoreline Label allows adding islands after defining an area, creating a hollow shape.

**Importing and Exporting Annotation Files** Users can import kml or dvp files of points, lines, and surfaces by selecting **\[Labels > More]** and clicking **\[Import]**. Both single file import and batch import are supported. After import, a new folder is created under the annotation information in the left panel. Similarly, users can export annotation files by selecting **\[Labels > More]** and clicking **\[Exporting]**. It supports .kml and .dvp export for points and lines, kml format export for surfaces, and .xml export for shorelines. Users can choose to export the whole annotation, a kml format export for surfaces, and a .xml export export for shorelines. Users can choose to export the entire annotation, single annotation, or multiple annotations at once, and the default export path is the last output directory. ## Measure ### Coordinate Measurement Users can perform coordinate measurements by clicking any point on the model with the left mouse button. ![Coordinate Measurement](/files/ky075jqtddSsoL43gt69) ### Distance Measurement Users can left-click multiple points on the model to draw folded line segments for distance measurement. During the drawing process, the user can undo the previous operation by pressing the Backspace key. The view shows the plotted trajectory as a "red" line and the total distance in real-time. At the same time, the "green dotted line" shows the horizontal distance between the start and end points (level distance), and the "blue dotted line" shows the difference in elevation between the two points (height difference). If the model obscures the line segment, it is shown as a dotted line; the portion of the line of sight not obscured is shown as a solid line. ![Distance Measurement](/files/g9kk2cgqRr9RCNd8ONgd) ### Area Measurement Users can draw polygons for area measurement by clicking points on the model surface with the left mouse button. Double-clicking the left mouse button closes the polygon, and the drawing process can be undone by pressing the Backspace key. After the drawing is finished, the system automatically calculates and displays the perimeter and area of the polygon, and the measurement result is saved to two decimal places. ![Area Measurement](/files/GEGbcv0Z3zoMlByryxD6) ### Volume Measurement Users can define the datum plane by clicking the points on the model surface and then double-clicking the closure to complete the drawing of the volume area. The user can undo the operation using the \[Backspace] shortcut during the drawing process. The user can set the height of the datum and the sampling distance, and the system automatically calculates the volume according to these settings and displays the results of the perimeter, area, and fill and excavation analyses. Measurement results are retained to 2 decimal places. ![Volume Measurement](/files/Rw7ZjDm6LObJKQ1fmRrx) ## Excavation Measurement The Excavation Measurement function is an advanced 3D GIS analysis tool that allows users to calculate the volumetric differences between selected ground surfaces and the model. This feature is of great practical value in civil engineering, terrain analysis, and urban planning. * **Explanation of Earthwork Calculation Results** * **Excavation volume (m³):** This is the volume above the volumetric base portion, i.e., the portion to be excavated from the surface. * **Fill volume (m³):** This is the volume below the volumetric foundation portion, i.e., the portion that needs to be filled to reach the foundation surface. * **Volume difference (m³):** this is the difference between the volume of the excavation and the volume of the fill, indicating the change in the total volume. * **Datum Plane Explanation** * **Highest Point Plane:** The base plane is parallel to the XY plane and is at the highest height of all vertices. Recommended when calculating the fill volume of a sand pit, pool, pond, etc. * **Lowest Point Plane:** The foundation's surface is parallel to the XY plane, and the height is at the lowest vertices. This is recommended when part of the boundary is not visible, e.g., when walls partially surround the inventory. * **Average Point Plane:** The base surface is parallel to the XY plane and the average height of all vertices. * **Center Point Plane:** It connects the Highest and Lowest points, and the base surface is parallel to the XY plane; the High is the highest height of all vertices, and the Low is the lowest of all vertices. * **Fit Plane:** Fit the plane to the vertices so that all vertices are at the minimum distance from the base surface. This is recommended when the entire perimeter of the pile is visible, and the base surface is hard, sloped, or at a level of the same height. * **Custom Surface:** The base surface is parallel to the XY plane and has a custom height. This option is recommended when walls surround the inventory, and only part or none of the boundaries are visible, but the height of the flat base is known. ![Datum Plane Explanation](/files/a1Ph89Jb1D4Nn4rZUGDO) 1. Draw the measurement area: Click the left mouse button to draw the polygon area to be measured. Each click creates a vertex, and a double click completes the polygon.

1. **Set Source Data Path** Users need to select the OSGB or OBJ data path to be converted. The file organization should meet specific requirements to ensure the conversion's accuracy. 2. **Set Input Coordinate System** When the user selects OSGB/OBJ data, the system automatically tries to read the coordinate system information from the data's Metadata.xml file. If the metadata file is not found or does not contain coordinate system information, the user must manually select or enter the appropriate coordinate system. 3. **Set Input Coordinate Origin** Similarly, the system tries to read the coordinate origin information from the Metadata.xml file. If the data is missing, the user needs to provide it manually. 4. **Set Output Data Path** Users need to select the output path of the converted data. 5. **Set Output Coordinate System** 6. **Set Output Coordinate Origin** The user must set a new coordinate origin for the output data. The system will attempt to read the coordinate origin information from the source data, but the user can also edit and modify it as needed. 7. **Set Conversion Method**

The system provides four types of coordinate transformation to meet the needs of different scenarios: * **No ellipsoid conversion required: I**t applies to transformation between different coordinate systems under the same ellipsoid. * **Direct translation method:** Allows users to input the translation amount of the xyz-axis to realize the direct translation of the coordinate system. * **Four-parameter conversion:** Applies to the transformation of any plane coordinate system with a point range within 10 kilometers. This transformation requires at least two control points and performs only plane transformation without changing the height information. * **Seven-parameter conversion:** This transformation requires at least three control points and involves both planar and elevation transformations for all point ranges more significant than 15 kilometers between different ellipsoids. 8. **Submitting tasks** When the user has filled in all the necessary information according to the requirements, he can click the **\[Export]** button to start the coordinate transformation. After the conversion, the user can find the converted OSGB/OBJ data in the specified output path. ## Watermark {% hint style="success" %} Watermark is VIP feature, only available to member users. {% endhint %} Users can add text or image watermark to model files. This function effectively prevents the model files from being illegally copied or stolen and protects the rights and interests of the creators.

* **Text Watermark:** When selecting a text watermark, users can customize its content, including text editing, font selection, color selection, and so on. In addition, users can adjust the watermark's visibility, rotation angle, horizontal spacing, and vertical spacing to ensure that it has the best visual effect on the model. * **Image Watermark:** To create an image watermark, users can select an image and make appropriate adjustments such as visibility, rotation angle, horizontal spacing, and vertical spacing. This way, users can add their logo or a specific image as a watermark to the model to further enhance its recognition and copyright protection. * **Watermark Preview and Model Export:** For local models, users can preview the watermark effect after adding the watermark. Users can export the model file with a watermark if the effect is satisfactory.

## Manage Tiles The user selects a specific set of tiles based on certain conditions or areas. Tiles often break up large maps or models into smaller, more manageable pieces. ![Tile Management](/files/pqm3J2ZwNQD5QUBqIJvj) * **Select All Tiles:** This feature allows you to select all tiles in the currently displayed model with a single click, greatly facilitating quick manipulation of the overall data. * **Cancel Selection:** This function allows the user to deselect all or specific tiles when they are no longer needed. * **Draw Selection:** Users can select tiles by adjusting the range of boxes to be drawn, which is especially useful for scenarios that require tile data in a specific area. * **Import Selection:** This feature allows users to import external TXT, kml, and shp files and automatically detect and select the tiles corresponding to those files. It is useful for interacting with data from other systems or platforms. * **Export Name Selection:** The user can export the selected tiles to a txt file for further data processing or analysis. * **Export Tiles Selection:** Besides exporting the selection set, the user can directly export the raw data corresponding to the selected tiles to the destination folder. This feature is handy when you need data from a specific area, and it will also crop the model data between tiles. * **Remove Tiles Selection:** This feature allows users to remove selected tiles at the display level without affecting the original data. This means that when the user reloads the model, these tiles will be displayed again. In addition, the user can use the Esc key as a "clear" shortcut to quickly deselect tiles. # Get3D GeeInsight # Basic Information # About GeeInsight **GeeInsight** is an all-in-one point cloud post-processing software , designed for post-processing data collected by the **Get3D R200 LiDAR scanner**.

With a single operation, the software can generate multiple outputs, including colorized point clouds, photo-realistic point clouds, Mesh models, and 3DGS models. Processing settings include point cloud computation and scene type selection, point cloud optimization, preprocessing, and reconstruction. Users can proceed using default parameters for standard workflows or customize parameters according to specific project requirements. {% hint style="info" %} **Note:** Successfully completed subtasks are automatically skipped during reprocessing. To recompute the workflow from the beginning, use the **Reset** function first. Changes to earlier processing steps will affect subsequent steps, and modifying upstream settings will cause the downstream operators to be executed again. {% endhint %} ### 2.1 Scene Type After the raw data is added, the algorithm performs point cloud computation based on the selected acquisition scene type to achieve optimal processing results. Supported scene types are described as follows: * **General Scene**: Open environments with spacious ground areas and façades, such as parking lots, large indoor venues, campuses, or plazas. * **Narrow Scene**: Long and confined environments, such as corridors less than 1 meter wide, mine tunnels, or small indoor spaces. * **Dynamic Scene**: Environments with significant movement of people or vehicles, such as traffic tunnels, streets during rush hour, or operating shopping malls. ### 2.2 Control Constraint The software supports position adjustment based on Ground Control Points (GCPs) or RTK data to generate point clouds with absolute coordinates. When GCP-based optimization is applied, the system can automatically export a point cloud accuracy verification report (Figure 66). #### **2.2.1 Using GCP** This function transforms the point cloud map into an absolute coordinate system using control points. Control points are introduced during mapping to perform adjustment calculations, resulting in a globally consistent point cloud dataset. Two methods are supported: * **Pick GCPs from the point cloud** — suitable when GCPs were not surveyed during acquisition. * **Read GCPs from raw data** — suitable when GCPs were collected during acquisition. At least 3 points are required, with 4 or more recommended. {% hint style="info" %} **Note:** The control point reference coordinate file must be prepared and imported by the user. The file format is a TXT file with columns arranged as: **Point ID, X, Y, Z**, separated by spaces. {% endhint %}

In the Data Management panel, right-click the GCP of the corresponding station and select **Edit** to open the **Edit Control Points** panel. Functions are described below: 1. **Open Coordinate File** — Load a GCP file or a previously saved point-pair file. 2. **Save Coordinate File** — Save the configured point-pair relationships as a file. 3. **Pick Reference Point** — Enables point picking in the point cloud. After selecting a row in the GCP list, pick the corresponding reference point in the viewer; the selected point is displayed as a yellow marker. 4. **Add Point** — Add a new row to the list. 5. **Delete Point** — Delete the selected row. **(1) Workflow for “Pick from Point Cloud”** {% stepper %} {% step %} **Import GCP file** Import the local GCP file into the **Edit Control Points** panel. The system automatically detects and displays the coordinate system. {% endstep %} {% step %} **Match Reference Points** Select each GCP row, click **Pick Reference Point**, and select the corresponding location in the point cloud. {% endstep %} {% step %} **Confirm Position** After all points are picked, click **OK**. The system performs GCP optimization and outputs a point cloud in the absolute coordinate system (consistent with the GCP file). {% endstep %} {% endstepper %} **(2) Workflow for “Read from Raw Data”** Import the local GCP file. The software automatically matches reference points with control points.\ Check the pairs marked **Convert** and click **OK** to save the task. #### **2.2.2 Using GNSS** This function improves accuracy by tightly integrating RTK data with LiDAR SLAM results and converts the point cloud into the selected coordinate system. The following conditions must be met: * The R200 RTK module must be used during acquisition. * A CORS account must be logged in via the mobile app beforehand. The system automatically recommends a projected coordinate system based on RTK data. Users may modify it or define a custom coordinate system. Supported coordinate transformation methods include: * Direct Method (offset/constant shift) * Four-Parameter Transformation * Seven-Parameter Transformation (parameters can be calculated using **Tool → Parameter Calculation**) **PPK Processing Support:** PPK processing is supported. Place the processed file into the pos folder of the original project and name it **PPK.txt**. Then select the PPK mode in the interface to perform computation. This is suitable for areas without CORS network coverage. The transformation name can use either newly calculated parameters or previously saved transformation parameters. {% hint style="info" %} **Note:** * IE software is recommended for PPK processing. * File columns must be ordered as: Date, GPSTime, Latitude, Longitude, H-Ell, PDOP, HDOP, VDOP, Q, Z-ECEF * The recommended time interval is **0.2 s**. {% endhint %} ### 2.3 Output Setting The Point Cloud Optimization module automatically refines the dataset according to the acquisition scene and strategy, removing layering artifacts in the map (enabled by default). #### **2.3.1 Dynamic Filtering** Dynamic Filtering is designed to eliminate moving objects, floating noise, and other artifacts in the point cloud, resulting in a flatter surface and thinner planar structures for improved data quality.

#### **2.3.2 Point Cloud Smoothing** Point Cloud Smoothing reduces noise while preserving geometric features. It minimizes errors caused by excessive point thickness and improves overall accuracy, producing a smoother point cloud that better approximates the original surface. When this option is enabled, the software automatically performs Dynamic Object Removal by default to ensure optimal results. #### **2.3.3 Coloring** This function assigns color information to the point cloud by mapping image textures onto the points, making the dataset more vivid and realistic. When it is selected, Dynamic Filtering and Point Cloud Smoothing must be executed. #### **2.3.4 Visual Optimization** Visual Optimization refines image poses to correct color misalignment and achieve higher-quality colorized point clouds. This function requires additional processing time and disk space. ### 2.4 Point Cloud Reconstruction Point Cloud Reconstruction supports the generation of Photo-Level Point Clouds, Mesh Models, and 3DGS Models. * **Dense Point Cloud**: After colorization, the system performs densification and densified color mapping. Compared with standard colorized point clouds, this provides better visual detail, improved geometric structure, and more faithful texture representation. * **Mesh Model**: Uses the smoothed, colorized point cloud together with visually optimized image poses as input. A surface reconstruction algorithm converts the point cloud into a textured 3D mesh model. * **3DGS Model**: Based on the smoothed, colorized point cloud and optimized image poses, the system generates a 3DGS model using the 3D Gaussian Splatting algorithm. ## 3 Reset **Reset Computation** resets the results generated by Point Cloud Processing. After resetting, the data returns to the state obtained from the initial computation of the original input data, and all optimization and processing effects will be removed. ## 4 Alignment **Point Cloud Alignment** is used to align two point clouds with overlapping areas. One dataset is defined as the **Reference Point Cloud** and the other as the **Floating Point Cloud**. By adding three or more pairs of corresponding points (tie points) in the operation view—ensuring the points are not collinear and are evenly distributed across the survey area—the software automatically performs coarse registration followed by fine registration. This transforms the Floating Point Cloud into the coordinate system of the Reference Point Cloud, producing an aligned result. 1. In the Data Management Panel, left-click while holding **Ctrl** to select two groups of point clouds from different stations.\ *Figure 72 Point Cloud Alignment Data Selection* 2. Click the **Alignment** button to open the alignment interface. 3. Enter the function interface to operation. Detailed steps: {% stepper %} {% step %} #### Select Reference and Floating Point Cloud Use the drop-down selection box to define the **Reference Point Cloud** and the **Floating Point Cloud**. * **Reference Point Cloud**: Its coordinate system remains unchanged during alignment. * **Floating Point Cloud**: Its coordinates will be transformed to match the Reference Point Cloud. {% endstep %} {% step %} #### Adjust Point Cloud Adjust the rendering mode of both datasets using **Point Cloud Adjustment** to make corresponding point selection easier. {% endstep %} {% step %} #### Select Corresponding Points Select three or more pairs of corresponding points in the view window. The index numbers of each pair must match. To delete a selected point, right-click the point in the view to open the context menu and remove it. {% endstep %} {% step %} #### Preview After selecting at least three pairs of corresponding points, click **Align** to execute the process. When completed, click the preview window to view the aligned result. {% endstep %} {% step %} #### Confirm Click **OK** to confirm and save the alignment result. The Floating Point Cloud will then be permanently aligned to the Reference Point Cloud. {% endstep %} {% endstepper %} ## 5 Panorama / Photo **Panorama / Photo** module provides an interactive display mode linking point clouds with images, including **Split-Screen View** and **Panorama View**. Both modes visualize the relationship between point clouds and photos. Click the corresponding function button to switch between the two display modes.

* **Split-Screen View** simulates a first-person perspective for browsing point clouds or images, allowing users to inspect the alignment between point cloud positions and photo locations. * **Panorama View** overlays the point cloud with panoramic images, enabling direct measurements on the panorama with point cloud assistance. To enter Panorama / Photo mode, first open the **Camera** data within the station and set it to visible. The images will appear in the main data view as 3D spheres. Double-click any sphere in the main view to enter Split-Screen or Panorama mode.

In Split-Screen mode, **Point Cloud Linked** is enabled by default. When switching viewpoints, both panels remain synchronized at the same perspective. If unchecked, the point cloud and image views can be navigated independently.

Use **Previous Frame** or **Next Frame** to automatically switch viewpoints. You may also click **Play/Pause** to automatically play or pause frame transitions. Keyboard shortcuts are supported: * Press **A** to switch to the previous frame * Press **D** to switch to the next frame * Press **ESC**, or click the **×** in the upper-right corner of the main view, to exit this mode

Note: The content below is for reference only. ## Precautions for flight * Operating unmanned aerial vehicles carries certain risks. Always prioritize safety while flying and avoid crowds. * Before the unmanned aerial vehicle flies, please verify the local laws, regulations, and relevant national regulations to ensure that the flight mission is conducted in a manner that is both legal and safe. Additionally, please review the appropriate policies and safety guidelines for Xinjiang. * Before the flight, we should thoroughly understand the site conditions (including building height, wires, buildings, and crowds) of the area where the route passes. * Before flying, inspect the UAV equipment, including the aircraft, remote control, and connecting devices, to ensure that sufficient power is available. * signals ## Flight acquisition tutorial The degree of overlap between flight and high-quality photos is a key factor that influences the quality of the final 3D model. Data collection for three-dimensional modeling using consumer-grade uncrewed aerial vehicles is divided into two categories: surround and route shooting. Surround shooting involves capturing objects layer by layer at various heights based on the flying mode of interest points. This process entails manually flying around and capturing photos of surrounding buildings, which is suitable for three-dimensional models of a single building. ### Surround shooting: Surround the shooting objects layer by layer at varying heights based on the flying mode of interest points. This involves manually flying around and capturing photos of the surrounding buildings, which is suitable for three-dimensional modeling of individual building. #### Precautions * Surround shooting is generally used for a single building or a single building. * Ensure the aircraft and remote controller signals are good during flight * In manual photos, ensure that the overlap between the left and right adjacent images, as well as the upper and lower adjacent photos, is at least 2/3 * Take a series of downward-facing photos of the object to be photographed. #### Procedure Take the Dajiang Genie 4 Series as an example; the flight software is DJI GO 4.T * Set the return altitude in the DJI GO (or DJI GO 4) to a safe height, typically not lower than the height of the buildings in the flight area. Ensure that the remote control is set to your preferred operation mode. * The takeoff aircraft hovers near the photographed object and adjusts its camera angle accordingly. Adjust the aircraft's angle so that one-third to two-thirds of the shot includes the ground (this ground photo is taken to ensure the integrity of the ground information), while the rest features the object to be captured. * Move the aircraft horizontally along the object to be photographed, and operate the camera to capture images simultaneously. The camera's picture controls the degree of overlap between the two images, which is typically at least two-thirds. After the first round of shooting, raise the aircraft to a height where the image overlaps two-thirds with that from the first round, and perform the second round of surrounding shots at this height. * Repeat the above steps to capture photos from different heights until the camera frame includes a top view of the object being photographed. * After tilting the camera angle to 45 °, take the photos. Adjust the camera to a 90° angle facing downward, ensuring the aircraft is 10 to 50 meters higher than the object being photographed (if the object is taller, fly higher). Then, begin taking photos of the object from above. The overlap between the two adjacent images should be at least two-thirds. ![](https://saas.bk-cdn.com/t/8731847e-01c8-438b-9575-3484e4c58acf/u/83148d6f-a632-424c-b1e3-0cb734324a96/1714384732560/image.png) ### Route shooting: The route is planned according to specific parameters, and the aircraft autonomously collects photos along the route, primarily aiming to achieve three-dimensional digitization of large areas such as city modeling, site modeling, park modeling, measurement, and other application fields. #### Precautions * Ensure the aircraft and remote controller signals are strong during flight. * In parameter setting, the height is usually set to 30 to 100 meters above the tallest building in the test area. * When many tall buildings are in the test area, increase the course overlap rate and side overlap rate. #### Procedure This example utilizes a Dajiang Genie 4 Series uncrewed aerial vehicle, with the flight software executing route shooting for the DJI GS PRO. * Open the DJI GS PRO software and click in the lower-left corner to access the flight task list. * Click the plus sign in the lower-left corner to create a task and select the 'Mapping Aerial Photography Area' mode. ![](https://saas.bk-cdn.com/t/8731847e-01c8-438b-9575-3484e4c58acf/u/83148d6f-a632-424c-b1e3-0cb734324a96/1714384756384/image.png) * Click on the map to select a point, and then click the area displayed on the screen. At this moment, a quadrilateral will appear, outlining the flight path.
