When use the software for the first time, click New Project to generate a project folder containing .m3d project files. When you open the project later, you can double click the .m3d file directly.
In the Data Manage page where you can import data, click Add Photos to open the Import Photo Pose Setting window.
Click Add Aerial Photos to import the data folder into the software.
After importing, the interface before positioning is as follows:
There are two ways to position imported images.
Select the photo group that Exif Information exist, right-click and select Read Exif to give photos position.
If successful, Photos with Pose value will change to green. The interface after successful positioning is as follows:
Click "OK" finish importing and positioning photos.
The second way of positioning is based on the pose file. Select the photo group, right click and choose pose file positioning, import pose file.
For the photos after importing the pose file, select any group and the pose setting screen will appear below.
Select the correct Spatial Reference System to correspond each column of data to its coordinate system units.
Then click Apply to Photo Group.
Select the group to correspond to and click OK.
If successful, the following window appears.
Click OK to complete the photo import and positioning.

When the photo positioning is finished, click Apply in the bottom right corner to save the block.
Click Settings on the top menu bar to open the Engine Settings window.
There are two paths that need to be specified for the Engine Setting: the Task Directory and the Local Engine Directory.
Make sure the task directory and monitor directory are same to start the Engine.
Click Start Local Engine to open the Engine screen.
The engine status is Waiting when no tasks have been submitted. Engine specific information can be viewed in the Engine window.
Once the Engine Setting is complete, you can click Submit AT. If you do not fill in the sensor parameters and focal length information, a prompt box will pop up, select Fill to fill in the camera information.
Fill in the correct sensor parameters and focal length information according to the camera model.
Note there is a difference between the focal length of the lower view lens and the focal length of the side view lens, please fill in correctly.
Once the camera information is filled in, continue back to the General view and click Submit AT to open the AT Settings window, click Submit.
Aerial Triangulation is submitted, calculations pending...
At the end of Aerial Triangulation, the generated point cloud model can be viewed in the 3D view

For blocks that have completed Aerial Triangulation calculations, right-click block and select New 3D Reconstruction or click the New 3D Reconstruction in the right bottom side to enter the Reconstruction screen.
In the Reconstruction Settings screen, you can perform operations such as selecting Coordinate System and setting the width of each modeling’s Tile.
In the Reconstruction Settings screen, you can perform operations such as selecting Coordinate System and setting the width of each modeling’s tile.
By clicking Submit Production, you can select the type of production you want to output. Get3D Mapper supports many types of production output.
Click on Select Tiles to selectively model parts of the entire interior of the area.
After all the settings are done, you can click OK to submit the production and enter the reconstruction calculation.
After modeling, you can click 3D View to view the modeling effect within the Mapper software interface.
You can also choose to view the product and link Get3D Viewer software with one click to view the model.

Right-click block and select New 2D Reconstruction or click the New 2D Reconstruction in the right bottom side to enter the Reconstruction screen.
In the Reconstruction Settings screen, you can perform operations such as selecting Coordinate System and setting the width of each modeling’s tile.
By clicking Submit Production, you can select the type of 2D production you want to output. DOM and DSM product are supported in 2D reconstruction. Set the resolution for DOM/DSM.
Click on Select Grids to selectively model parts of the entire interior of the area.
After all the settings are done, you can click OK to submit the production and enter the reconstruction calculation.
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 can be completed before importing the laser data for fusion modeling.
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.
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.
