4 - Merge grids from multiple scans (LVOX 3)
Plugin : LVOXNom de classe : LVOX3_StepMergeGrids
Description
This step allows for merging grids created from multiple scans of a point cloud scene. A new version of the grids is generated.
Paramètres
Step parameters:
- Merging method: String with the following possible values =
- Max density : Compute with max(nbi)
- Max trust : Compute with max(nt - nb)
- Max trust ratio : Compute with max((nt - nb)/nt)
- Max hits : Compute with max(ni)
- Sum ratio : Compute with sum(ni)/sum(nt - nb)
- Weighted rdi : Compute with sum((nt - nb) * rdi)/sum(nt - nb)
- Weighted rdi alt. : Compute with sum((nt - nb) / (nt * rdi)) / sum((nt - nb) / nt)
- Ignore zero density voxel: booleandefault = true
- Minimum effective rays: integerdefault = 5 applies whenever using (nt - nb)
- Use relative threshold: booleandefault = false applies whenever using (nt - nb)
