4. Reconstruction Tasks

Different image acquisition devices may provide POS (Positioning and Orientation System) data in different formats and with varying parameters. The software provides users with corresponding functions to edit POS data.

📄️ 4.3 Setup Multiple Camera

The Set Camera function is mainly used for multi-camera reconstruction scenarios. When users import photos, the software automatically parses the file structure and photo information of the imported photos, and automatically groups the photos into different cameras based on the camera parameters (focal length, sensor size, intrinsic parameters, distortion, etc.) in the photos. If camera parameters cannot be parsed from the photos, or if the camera parameters are incorrect and need to be manually entered, users can use the "Edit Camera" function to set the camera parameters.

📄️ 4.4 Preset Region of Interest

Under normal circumstances, the data collection range will exceed the target region of interest. Especially in scenarios involving surround photography of individual buildings like houses, the reconstructed image data will contain a background much larger than the individual building. Reconstruction in these scenarios wastes significant computing and storage resources. This software provides users with a preset region of interest function before any data processing, allowing reconstruction range limitation through external range file import or manual editing.

📄️ 4.5 Execute Aerial Triangulation and View Results

The software supports separate aerial triangulation and reconstruction. If the task only requires aerial triangulation, or if you need to set the region of interest more precisely, you can proceed as follows:

📄️ 4.6 Setup Ground Control Points

Ground Control Points (GCPs) are primarily used to improve aerial triangulation accuracy. Setting GCPs can be done before or after aerial triangulation processing.
