改进了LiDAR点云数据处理滤波算法的判断条件,运用四种坡度阈值判断数据点的地形信息,实现了改善滤波效果的目的。
The judgment conditions of LiDAR point cloud data processing and filtering algorithm are improved, and the four kinds of gradient thresholds are used to judge the topographic information of the data points, so as to achieve the purpose of improving the filtering effect.
