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.
4 Other Features
4.1 New Features
4.1.1 Save to Camera Database
Allows users to add or save camera parameters in the software, reducing the need for repeated manual input.
①Select a photo group, input or import camera parameters, and click "Save to Camera Database".
②If parameters for the same model exist, a prompt will appear.
③Click OK to navigate to the camera database management interface for further edits.
4.1.2 Model Origin Setting
Supports multi-origin planning for efficient management of large-scale datasets in projects.
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:
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.
Please refer to 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).
