How can extracted the building point, vegetation and ground point for terrestrial laser scanner data (point cloud) please suggested the publication and automatic MATLAB code.
There are specialized tools for feature extraction, rectification, etc, for lidar data - I'd use those vs. MATLAB. And none of them are auto-magical, depending on the scene.
Dear michael john patrick
thanks for reply please can you given a like those type of link which is very valuable for me.
Vinamra Bhushan Sharma Your request indicates that perhaps you may not have already familiarized your self with the basic fundamentals of the technology. It would helpful to you if you explained your knowledge, skills and experience and what you have found out yourself as a starting point. What follows is a short list of various aspects and types of Lidar, which generate various sorts of point clouds, which then have optimal algorithm(s) for feature extraction in situation from bone fragments to asteroids - otherwise your essentially asking me to teach a class on Lidar:
