PROBLEM TO BE SOLVED: To easily adjust the conversion rule of an object camera for adjustment even when a calibration pattern is set in a range where the imaging range of the object camera for adjustment and the imaging range of a reference camera do not overlap.SOLUTION: By using a calibration sheet (31) having a pattern A and a pattern B, the pattern A is arranged in an imaging range SF of a front camera (5) as an object camera for adjustment, and the pattern B is arranged in an imaging range SL of a left camera (7) as a reference camera. Both patterns A and B are not arranged in an overlapping range SFL of both cameras (5, 7). In this case, the pattern A can be imaged by the front camera (5), and a positional relation between the pattern A and the pattern B is already known so that a pattern B' can be calculated from the pattern A. Therefore, it is possible to change the conversion rule of the front camera (5) such that the coordinates of the pattern B' match the coordinates of the pattern B. |
