Abstract
A technique for performing calibration of a laser scanner efficiently is provided. Point cloud position data of a building 131 is obtained by a laser scanner 141 in which exterior orientation parameters are already known. On the other hand, the building 131 is scanned by a laser scanner 115 while a vehicle 100 travels, and point cloud position data of the building 131 measured by the laser scanner 115 is obtained based on a trajectory the vehicle 100 has traveled. Then, exterior orientation parameters of the laser scanner 115 are calculated based on a correspondence relationship between these two point cloud position data.
