机载LiDAR点云更新1∶1万DEM关键技术探讨

Review on DEM Key Technologies of Airborne LIDAR Point Cloud with the Scale of 1∶10000

摘要:

结合TerraSolid对机载激光雷达数据进行后处理的生产流程，重点分析利用LiDAR数据提取DEM的几个关键技术：滤波技术、航带拼接技术、特征线\特征点参与DEM构建技术以及点云人工编辑分类后航带间高差超限的补救性处理方法。

Abstract:

Combining with post processing of TerraSolid software to airborne LIDAR data, few key technologies of DEM extracted by using LIDAR datas have been analyzed, including filtering technology, aircraft belt splicing technology, feature lines and feature points involved in DEM extraction and the remedial treatment after manual classification with the height difference between flightlines.
