A useful tool to cut a set of point cloud into two parts with a designed IoU (overlapping)

IoU (ranging from 0 to 1) is calculated as the number of points in intersection area over the point number of the original point cloud.

For example, for a cut into two non-overlapping segmentations, IoU should be set as 0.

Select from 1.X, 2.Y, 3.Z direction for cutting the point cloud.

Do a quick sorting for the point cloud along the designed direction.

Then cut the sorting point cloud into two parts.

One cloud ranges from Point {1} to Point {(0.5+IoU/2)*PCsize}.

Another cloud ranges from Point {(0.5-IoU/2)*PCsize} to Point {PCsize}.
