基于无人机LiDAR的高压输电线路树障监测与分析OA
Monitoring and analysis of high-voltage transmission line tree barrier based on UAV-LiDAR
基于无人机LiDAR点云数据,利用LiDAR360软件对研究区域的点云数据进行点云平滑、重采样和去噪等预处理,随后采用克里金空间插值算法生成数字高程模型(DEM)和数字地表模型(DSM)并进行了精度检验,进而利用ArcGIS软件对DSM和DEM进行相减得到了冠层高度模型(Canopy Height Model,CHM),最后利用以焦点统计为主的一系列空间分析方法对CHM进行了单木树高和单木位置的提取.然后对研究区域内的高压输电线路沿线树木进行了排…查看全部>>
Based on the unmanned aerial vehicle LiDAR point cloud data,the LiDAR360 software was used to pre-process the point cloud data in the study area,including point cloud smoothing,resampling and denoising.Then the Kriging spatial interpolation algorithm was used to generate the digital elevation model(DEM)and digital surface model(DSM),and accuracy testing was conducted.Subsequently,the ArcGIS software was used to subtract the DSM and DEM to obtain the canopy h…查看全部>>
