摘要
Abstract
A filtering method for airborne LiDAR point clouds is proposed based on point cloud segmentation. The point cloud segmentation, based on the features about normal difference and distance difference, is added into the classic progressive TIN densification. Experimental results show that, compared with the classic filter, the pro-posed method has a higher filtering accuracy with lower type I errors and total errors, and it is capable of better preserving discontinuity of landscapes.关键词
