Point Cloud Overlap
=========================

Computes the pairwise overlap of a set of dense point clouds

Input
-----

Two or more point clouds, all of which must be dense and calibrated (have intrinsics)

Output
------

For each pair in the input a point cloud containing the overlap if **Export overlap point clouds** is enabled, otherwise nothing 

Description
-----------

* **Distance Threshold**: Maximum distance in mm for points in different point clouds to be considered the same one
* **Angle Threshold**: Maximum normal angle in degrees for points in different point clouds to be considered the same one
* **Export overlap point clouds**: Makes the algorithm export the result to the data model
