Abstract: In order to meet the needs of high-precision spatial information acquisition, a new generation of mapping level vehicle mobile measurement system is developed based on the integration of high-end domestic LiDAR, inertial measurement unit and other sensors. This paper designs and optimizes the system communication bus, analyzes the factors that affect the system precision, puts forward the laser radar cone sweeping angle calibration method and the system whole calibration method, and puts forward the method of optimizing the POS data by using RTK. The accuracy of the system is the centimeter level. The system has been applied in the production of high-precision navigation map. It is proved that the system is easy to install, fast to collect and process, meets the needs of high-precision spatial data acquisition, and improves the efficiency and accuracy of high-precision spatial data acquisition.

Key words: vehicle mobile mapping system, system calibration, network RTK, point cloud, high-precision navigation map
