摘要： An object of the present invention is to simplify a calibration operation of a camera and to shorten a time necessary for calibration. A camera calibration device 10 is mounted on a predetermined position of a movable object 100 and includes a camera 11 configured to take an image including an index 41 provided outside the movable object 100, an image superimposing unit 122 configured to generate a superimposed image by superimposing a calibration object 42 having a position adjustment part and a rotation adjustment part on the image taken by the camera 11, and a calculation unit 124 configured to calculate, based on a position of the calibration object 42 after being shifted in the superimposed image such that an end or a center of the index 41 meets the position adjustment part and a part of the index other than the end or the center overlaps the rotation adjustment part, parameters relative to a pan angle, a tilt angle and a roll angle for calibration of the camera mounting position.
