【摘要】 利用车载LiDAR技术，设计了一套从移动测量车数据采集、点云数据处理到高精道路地图制作的完整流程。以武汉市中心城区3 km~2实验区内的市政道路作为研究对象，开展了高精道路地图的研制生产实验，实验成果精度可满足L3以上级别自动驾驶及城市1∶500地形图修测更新的需求。该技术已在相关行业逐步推广应用，并为相关工作提供参考。更多还原

【Abstract】 Based on vehicle-borne LiDAR data, this paper designed a whole process from mobile mapping system data acquisition, point cloud data processing to high-precision road map production. Taking the municipal roads in the 3 km2study area of the central area of Wuhan as example, a test of the high-precision road map production was carried out. The results show that the accuracy can meet automatic driving(above L3)requirements and 1∶500 topographic map updating.更多还原
