Research on Key Technologies of LiDAR Point Cloud Data Coordinate Transformation
LiDAR technology has become more and more mature in recent years and has been widely used in various industries. The LAS format standard provides convenience for LiDAR point cloud data exchange. In order to realize the coordinate transformation of point cloud da-ta,this paper realizes the coordinate transformation of LAS files based on LASlib library and coordinate transformation model,and verifies its correctness by using engineering projects. At the same time,the coordinate conversion efficiency of different coordinate conversion models is analyzed,which has guiding significance for the coordinate conversion of LAS files.
