摘要
文中介绍了TerraSolid、Li DAR Suite和Li DAR-DP三款软件功能,分析了软件各自优缺点,通过试验比较了软件在不同地形特征区域的激光雷达点云滤波效果。最后,提出了一种结合TerraSolid、Li DAR Suite和Li DAR-DP软件处理激光点云数据,制作数字高程模型(DEM)的技术方法,为高精度DEM生产提供参考。
The functions of TerraSolid software,Li DAR Suite software and Li DAR-DP software were introduced,the advantages and disadvantages of the software were analyzes,then,the LIDAR point cloud filtering effect of the software in different terrain features was compared by experiments. Finally,a method combining with TerraSolid,LiDAR Suite and Li DAR-DP software was proposed to process Li DAR point cloud data and make DEM providing a reference for high precision DEM production.
