摘要: 在扫描过程中车载移动测量系统,主要获取道路两侧数据。受建筑物等的遮挡,获取的数据不完整,部分区域GNSS信号不好,造成数据精度下降,很难单独完成某一工程任务。无人机LiDAR数据精度高,空对地测量遮挡少,但其安全性、近地数据精细度不理想。基于车载移动测量与无人机LiDAR的优缺点及互补性,本文提出利用小型无人机LiDAR来完善车载点云数据,实现高精度快速数据采集方案。试验证明,该方案切实可行,能够大大提高车载移动测量系统的可用环境,值得推广应用。

Abstract: Vehicle-borne mobile mapping systems mainly obtain the data along both sides of the road in the scanning process.It will get incomplete data when it gets blocked,and the poor GNSS signal makes the data accuracy descend in partial area,so that it is difficult that vehicle-borne mobile mapping systems complete an engineering task separately.UAV laser radar has high precision data,and there are less covers when measuring in the sky,but the security and detail level of data near the ground are not ideal.Based on the merits,demerits and complementarity between vehicle-borne mobile mapping systems and UAV laser radar,this paper proposed a solution that achieves the high-precision and high-speed data acquisition by using small UAV laser radar to perfect the point clouds data of vehicle-borne mobile mapping systems.The experiment proved that the solution is feasible and can greatly improve the available environment of vehicle-borne mobile mapping systems,so it is good for popularization and applications.

Key words: vehicle-borne mobile mapping systems, unmaned aevial vehicle, laser radar, point clouds
