If I have some 3d points, how can I discover parallel planes within them (not just arbitrary planes).I want to know how many levels or floors something can travel within, after it has done so, so I want to cluster the positions into planes.Some of them might not be in a plane, most of them are noisy (not perfectly planar), and I have no knowledge of the world orientation, so the planes aren't necessarily orthogonal to some known axis.I know one way is a 3d-hough transform, but is there something better?
Best way to group 3d points into planes, if any
