Walls and Floors

images/download/attachments/113546342/CmdWallsAndFloors.svg

This command classifies points of a cloud into 3 categories:

  • walls,

  • floors and ceilings,

  • other.

Select the point clouds to classify and launch the command.

Note

This command computes locally the point cloud normal to make the classification. Consequently, any cleaning or segmentation done before, may result in a slightly different classification.
