摘要
讨论对LIDAR点云的高程值进行再次改正的必要性和改正方法,提出构建Delaunay三角网对LIDAR点云的高程值进行再次改正的方法,实例改正结果表明,改正后的LIDAR点云的高程精度能够大幅度提高。
The article discusses the necessity and the methods of further elevation value correction of LIDAR point cloud data,and emphasizes on the method of further elevation value correction of point cloud data by constructing Delaunay triangulation network.The result of the engineering case shows that the precision of cloud points of airborne LIDAR can be promoted greatly.
