@Alyssa, as Adam mentioned, the points assigned to the “disabled” group will not be taken into account when creating the 3D mesh.
After the points are assigned to the “disabled” group, the 3D mesh can be regenerated directly (no need to reprocess the whole Step 2.) from the menu tab by clicking Processing - Generate 3D Textured Mesh.
When it comes to removing the noise from the point cloud also this steps could help:
- Adding manual tie points or Ground Control Points (GCP) will help in the process of matching the images together and it can result in better-reconstructed scenes. If you introduce MTPs or GCPs the project needs to be reoptimized in order for the points to be taken into account. Keep in mind that all the results of Step 2. and Step 3. will be lost when performing the reoptimization.
Drawing surfaces that will be used in the generation of DSM and 3D Textured Mesh and will make the wavy and unflat surfaces planar.
- Generate more accurate point clouds by changing the processing options for the point cloud, changing the minimum number of matches from 3 to 4 or 5.
- Add a processing area in order to remove the noise in the sky/ edges of the project and to speed up the processing.
