Abstract
A first object and a second object arranged in an actual space with coordinates (Xn, Zn) and (Xn−D, Zn) are imaged, and respective coordinates xand xof the first object and the second object in the image are calculated. Then, a coordinate xof the first object in the image and a coordinate xof the second object in the image are calculated by equations:1=2=·()/where F is a design parameter of an imaging unit. An image distortion corrective value α to correct the design parameter F is calculated by equations:α·1*=1α·2*=2using a difference between the coordinates xand xand a difference between the coordinates xand x
