===== Parameters: Algorithm ===== | ===== Parameters: Algorithm ===== | ||
- | === Voxel Size === | + | Generic concepts, see [[dev: |
- | + | ||
- | The selected area is divided in voxels with a defined size. For every voxel, the change detection will give information on how many points are added or removed. | + | |
- | + | ||
- | For less dense point clouds, a higher voxel size should be used. | + | |
- | + | ||
- | === Voxels Change Pts Min === | + | |
- | + | ||
- | The minimum number of points that should be added or removed in a voxel in order to add the voxel to the result datasets. | + | |
- | + | ||
- | === Voxels Context Min === | + | |
- | + | ||
- | The minimum number of voxels that should be around a voxel in order to consider the voxel. This is done to exclude isolated voxels. | + | |
