PROBLEM TO BE SOLVED: To provide an imaging device calibration method or the like capable of calibrating a position and a posture of each camera without recognizing an accurate three-dimensional position of an object to be an imaging object, and uniformly correcting an error for the entire composite image.SOLUTION: The imaging device calibration method includes: a feature point setting step of setting a feature point by an object imaged in common by adjacent imaging devices with each other on respective image data of cameras 1-3 with each other, which are adjacent imaging devices; an initial position setting step of setting the relative position of another imaging device to the position of a specific imaging device among the plurality of imaging devices as an initial position expressed by using a rotary movement amount and a parallel movement amount; and an imaging device position correcting step of evaluating an error between the initial position and the actual position of each imaging device and correcting the position of each imaging device using the rotary movement amount, the parallel movement amount, and the coordinate value of the feature point. The initial position setting step includes a feature point distance setting step of using a rough distance to the object for setting the initial position. |
