A Calibration Method of Mobile Laser System Without Control Points.

Mobile mapping technology can be used to acquire geospatial data efficiently, accurately and at low cost, it is one of the most advanced technologies for geospatial data acquisition. A precondition for acquiring high quality point clouds using mobile laser systems is that the mobile system be well calibrated. Ground control points are used in the common method to calibrate mobile laser systems, but these methods as inflexible and it is labor intensive to collect ground control points. In this paper a mobile laser system calibration method using no ground control points is proposed, an actual system was calibrated using the proposed method, and its precision evaluated.
