A Calibration Method of Mobile Laser System Without Control Points

Mobile mapping technology can be used to acquire geospatial data efficiently,accurately andat low cost,it is one of the most advanced technologies for geospatial data acquisition.A preconditionfor acquiring high quality point clouds using mobile laser systems is that the mobile system be wellcalibrated.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
