PROBLEM TO BE SOLVED: To provide a calibration method that highly accurately calibrates an absolute position deviation on image data due to effects of a transparent body.SOLUTION: A calibration method of an imaging device photographing a subject via a transparent body includes: a step S1 of photographing the subject not via the transparent body to acquire a first photograph image; a step S5 of photographing the subject via the transparent body to acquire a second photograph image; a step S8 of, on the basis of a coordinate of an image of the subject of the first photograph image and a coordinate of an image of the subject of the second photograph image, calculating an absolute position deviation indicative of a deviation of the coordinates of the images of the subjects arising from the transparent body; a step S9 of calculating a correction parameter calibrating the absolute position deviation; and a step S10 of storing the correction parameter in the imaging device. |
