一种改进的LiDAR点云TIN迭代滤波算法

AN IMPROVED ITERATIVE TIN FILTERING ALGORITHM FOR LiDAR DATA

采用了设定最大内插距离和最大内插角度两个阈值,根据滤波次数动态调整了其值以达到最佳滤波效果,实现并改进了TIN迭代滤波算法。

We realized and improved the iterative TIN filtering algorithm. The results of the experiment with airborne LiDAR data in urban areas show that the algorithm is more applicable to urban areas, compared with the original iterative TIN filtering algorithm.
