4 - Merge grids from multiple scans (LVOX 3)

Plugin : LVOX
Nom 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)
