There are lot of objects in a point cloud and my task is to crop a particular object. I would like someone to help me on knowing the indices of points associated with the object and to crop it. I have seen the documentation in open3d site which crops using j-son file but it is not clear to me. I would like to know how to know the exact location of points in a point cloud.

Are you looking for a way to visually crop the objects, or are you looking for a smart way to segment the objects? For the former case, IDK if Open3D has a solution, but you can use MeshLab too. For the latter case, you can check [DBSCAN clustering](http://www.open3d.org/docs/latest/tutorial/Basic/pointcloud.html#DBSCAN-clustering) – Dilara Gokay Jul 28 '22 at 09:01
