Points on Grid

This command creates a regular sampled point cloud thanks to another point cloud and a grid.

Requirements

Select a point cloud and launch the command.

  1. Choose the extraction Mode. You have the following choices:

    1. Ground point: it will create points laying onto the ground of your point cloud

    2. Highest point: it will create points corresponding to the highest area of your point cloud (in the direction perpendicular to the grid)

    3. Lowest point: it will create points corresponding to the lowest area of you point cloud points (in the direction perpendicular to the grid)

  2. Define the Grid parameters:

    1. Define the Grid orientation (always in an horizontal plane)

    2. Enter the Grid step

    3. You can also Define a grid point i.e. a point where an intersection of the grid is supposed to be.

Notes

  • Depending on the grid and the point cloud, the computation could be long due to the amount of points to create.

  • Each point is extracted inside an infinite cylinder with a radius equal to grid step / 10 and respect the constraint of the chosen mode. Check Project points on the grid axis to keep a regular grid.
