Firstly, I need to find for each point in point cloud the neighboard points within 20 m in XY plane. After that from points within 20 m radius I need to find the Zmin and Zmax.

What have you tried so far? – serkan.tuerker May 07 '19 at 17:25

I get it done by using the cKDTree. It took around 7 min to process 10000 points. Since my point cloud is much larger is there something faster? – user10827304 May 09 '19 at 09:44
