无人机遥感技术制作DEM新方法

The New Method of UAV Remote Sensing Producing DEM

无人机遥感技术能够快速制作地表模型DSM,由于测区地物的存在,地表模型不能替代DEM,本文提出利用激光点云处理软件Terrasolid软件,通过高程分类算法对点云数据进行分类,通过人机互助快速提取出地面点制作DEM.

UAV remote sensing technology to rapidly produce surface model DSM,due to the existence of the survey area was surface features,surface model can not substitute DEM,this paper using a laser point cloud processing software terrasolid software,through the elevation point cloud classification algorithm for data classification,by people mutual fast machine to extract ground points make DEM
