PointCloudScissor

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

Now available on Windows.

PCL 1.8 needed

Compile with VS2013

How to use

1.Input the point cloud to be cut in PCD format.

2.Input the designed IoU (overlapping ratio)

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.

3. Select the cut direction

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

Principle

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}.
