摘要：With the rapid development of remote sensing technology, three dimensional coordinates and intensity information of observation target can be obtained directly from LIDAR system. It is one of the important issues in the study on LIDAR data processing that how to extract the object from the point cloud data captured by laser scanning effectively without the help of spectral information as well as other auxiliary data. In this paper, a method for the target extraction from the point cloud data in the absence of other auxiliary data is proposed. Experiment results indicate that the mentioned method can extract interesting object points from LIDAR point cloud data powerfully
