Calibration pattern unit photographed by an imaging system to acquire an image for obtaining correction information
A calibration pattern unit which obtains correction information of an imaging system by imaging at the imaging system is formed by combining a plurality of three-dimensionally arranged planes. The calibration pattern unit comprises supporting members each of which has a predetermined surface corresponding to one of the planes, and a calibration pattern in which a predetermined pattern is formed on the predetermined surface of the supporting member. The supporting member can selectively set the calibration pattern unit to a first form for photographing when the correction information is obtained, and a second form for other purposes.
