PROBLEM TO BE SOLVED: To eliminate the need of a large scale device in the case of 2nd calibration of a stereo camera to which calibration has been made once. SOLUTION: An arithmetic section 6 calculates rotation conversion and parallel movement conversion information for a stereo camera 4 based on calibration data in a 1st state that the stereo camera 4 is configured with combination of a 1st camera and 2nd and 3rd cameras integrated with the 1st camera and on calibration data in a 2nd state that the stereo camera 4 is configured with combination of the 1st camera and the 2nd and 3rd cameras which are separated once and then of the 1st camera and the 2nd and 3rd cameras which are integrated again. Then the calibration data with respect to the stereo camera in the 2nd state are calculated by using the rotation conversion and parallel movement conversion information. |
