摘要

PROBLEM TO BE SOLVED: To provide a technology capable of calibrating efficiently a laser scanner.SOLUTION: Point group position data of a building 131 are obtained by a laser scanner 141 having a known external orientation element. On the other hand, the building 131 is scanned by a laser scanner 115, while allowing a vehicle 100 to travel, and point group position data of the building 131 measured by the laser scanner 115 are obtained from a locus of the vehicle 100. Then, an external orientation element of the laser scanner 115 is calculated on the basis of correspondence between the two point group position data.SELECTED DRAWING: Figure 1
