Document Type and Number:

Japanese Patent JP6025365

Kind Code:

B2

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 device 10 includes: a camera 11 configured to take an image including a mark 41 provided outside a vehicle 100; an image superimposing unit 122 configured to generate a superimposed image by superimposing a calibration object 42 having a first adjustment part 421 indicating a predetermined area and a second adjustment part 422 indicating a predetermined rotation area; and a calculation unit 124 configured to control the image superimposing unit 122 to generate the superimposed image in which the calibration object 42 is shifted based on a shift instruction of the calibration object 42 and to calculate, based on a position of the calibration object 42 after being shifted in the superimposed image such that an end of the mark 41 is included in the area of the first adjustment part 421 and the mark 41 is positioned in the rotation area of the second adjustment part 422, parameters relative to a pan angle, a tilt angle and a roll angle for calibrating displacement of a mounting position of the camera 11.
