There are several tips that can help to correct building artifacts. The following methods are not exclusive and all or several of them can be used:
- Before Processing: Fly again with higher frontal and side overlap and if possible fly higher. If there is no need to reconstruct the facades of the buildings, it is recommended to fly with the camera pointing to the nadir: Vertical vs oblique imagery.
- Change the processing options for Step 2. Point Cloud and Mesh:
1. On the Menu bar, click Process > Processing Options...
2. Select the processing step 2. Point Cloud and Mesh.
3. Select the tab Point Cloud.
4. On the section Point Cloud Densification, deactivate Multiscale.
- Change the processing options for Step 3. DSM, Orthomosaic and Index:
1. On the Menu bar, click Process > Processing Options...
2. Select the processing step 3. DSM, Orthomosaic and Index.
3. Select the tab DSM and Orthomosaic.
4. On the section Raster DSM, select Method Inverse Distance Weighting.
