Abstract
Simple calibration of a camera mounted on a mobile object is implemented. With a joint means, a target apparatus for calibration is physically fixed to the mobile object having a camera mounted thereon. The positional relation between the vehicle and the target apparatus is finely adjusted while visually confirming a target point on the vehicle through a scope means.

9. A method for calibrating a camera mounted on a mobile object, comprising the steps of:
-
preparing a target apparatus for calibration around the mobile object;
fixing a position of the target apparatus such that the target apparatus has a prescribed positional relation with the mobile object, by using a positioning means provided to at least one of the mobile object and the target apparatus; and
capturing a feature point of the target apparatus with the camera, wherein the camera is calibrated based on a relation between image coordinates of the feature point and real-world coordinates thereof.
