Abstract
An object of the present invention is to simplify an operation for calibration of a camera and to shorten a time necessary for the calibration. A camera calibration deviceincludes: a cameraconfigured to take an image including an indexprovided outside a movable object; an image superimposing unitconfigured to generate a superimposed image by superimposing a calibration objecthaving a first adjustment partindicating a predetermined area and a second adjustment partindicating a predetermined rotation area; and a calculation unitconfigured to control the image superimposing unitto generate the superimposed image in which the calibration objectis shifted based on a shift instruction of the calibration objectand to calculate, based on a position of the calibration objectafter being shifted in the superimposed image such that an end of the indexis included in the area of the first adjustment partand the indexis positioned in the rotation area of the second adjustment part, parameters relative to a pan angle, a tilt angle and a roll angle for calibrating displacement of a mounting position of the camera
