Walls and Floors

images/download/attachments/173278186/CmdWallsAndFloors.svg

This command splits points of a cloud into 3 or 4 categories:

  • Walls,

  • Floors and ceilings,

  • Others.

Requirements

Select the point clouds to split and launch the command.


  1. Set the angular tolerance for walls (maximum angle with nadir-zenith line).

  2. Set the angular tolerance for floors and ceilings (maximum slope).

  3. You can change the slider for the Local Normal Smoothing. This slider allows you to increase or decrease the radius of the influence zone on a cloud, in order to take into account a bigger part of the cloud.

  4. Choose the point clouds to create:

    1. Walls to classify the points which meet the threshold.

    2. Floors and Ceilings to classify the points which meet the threshold. Floors and Ceiling are also segmented when all inputs have scanning directions.

    3. Other to keep other points.

Notes

This command computes local point cloud normals to segment it. Consequently, any cleaning or segmentation done before may result in a slightly different segmentation.
