Greeting,
I have sort of an opposite problem of point cloud registration. I am looking to detect whether some point cloud data that I have is disjoint. For example:
Is a single point cloud but is clearly discontinuous. My original thought into inspecting the distance matrix I think is moot since the "gap" might be roughly the same distance between several points (the corners) in the "individual" point clouds. The topology is subject to change so it's not safe to assume otherwise.
A literature search didn't turn up anything of interest to me. Any ideas?
