车载激光雷达在城乡道路带状地形图测绘中的应用

Application of Vehicle-borne LiDAR in Urban and Rural Road Strip Topographic Map Mapping

全野外人工进行1∶1000带状地形图测绘存在费时费力等问题,根据相关项目关于城乡道路带状地形图测绘的要求,本文提出一种利用车载三维激光扫描完成地形图测绘工作模式,对车载雷达数据的获取进行分析研究测试,并对车载激光雷达不同作业环境以及点云密度进行分析,通过精度检测和数据采集获取的效果以及数据获取效率进行验证。

1∶1000 strip topographic map mapping in the whole field by hand is time-consuming and laborious,according to the requirements of the corresponding projects for the mapping of urban and rural road strip topographic map,a work mode of using vehicle-borne 3D laser scanning to complete topographic map mapping is proposed.In this paper,the acquisition of vehicle-borne LiDAR data is analyzed and tested,and the different operational environments and point cloud density of vehicle-borne LiDAR are analyzed,through the precision detection and data acquisition results and data acquisition efficiency to verify.
