Paper Abstract

The coordinate systems related to the vehicle-based mobile laser scanning system and the relationships between them are firstly demonstrated in this paper, then the positioning principals of vehicle-based mobile laser scanning system are well established. Factors that influence the system positioning precision are analyzed briefly, including the misalignment angle and lever arm between Scanner Owned Coordinate System (SOCS) and IMU System. To calibrate the misalignment angle and lever arm between SOCS and IMU Coordinate System, a calibration field, which uses the building corners as reference points, is established. Based on the calibration field established, a calibration method is proposed and utilized in the calibration of our vehicle-based mobile laser scanning and urban panoramic imaging and surveying system, the verification experiment show that, under good GPS conditions and with the system well calibrated, the elevation accuracy is better than 4cm and the planimetric accuracy is better than 6cm.
