Laser LiDAR power line point cloud automatic point supplementing method

The invention discloses a laser LiDAR power line point cloud automatic point supplementing method. The method comprises the steps of 1 performing power line point cloud grading and coordinate conversion to obtain a power line point cloud set; 2 performing single-gear power line point cloud plane segmentation and gridding; and 3 performing point supplement calculation, namely performing point supplement on the power lines in the plane segmentation subsets. The technical problems of low laser LiDAR power line point cloud density and serious point cloud loss are solved, the workload of manual data processing is reduced, the point location precision of point supplement is improved, and data support is provided for subsequent functional applications such as power line reconstruction and dangerous point detection. 本发明公开了一种激光LiDAR电力线点云自动补点方法，它包括：步骤1、电力线点云分档以及坐标转换，得到电力线点云集合；步骤2、单档电力线点云平面分割以及网格化；步骤3、补点计算，对平面分割子集内的电力线进行补点；解决激光LiDAR电力线点云密度低、点云缺失严重的技术问题，降低人工数据处理工作量，提高补点的点位精度，为后续电力线重建、危险点检测等功能应用提供数据支持。
