Abstract
An image processing device includes an image input section inputting images taken by a vehicle camera, a calibration target specifying section specifying a calibration target included both in a first image and in a second image, a vehicle information input section inputting information indicating travel distance and orientation change of the vehicle, a calculation section, and a storing control section. The calculation section converts the first and the second images to the first and second bird's-eye view images, respectively, arranges the first and the second birds-eye view images on common coordinate system with consideration of corresponding image taking positions and image taking orientations, and calculates at least one orientation parameter of the camera which minimizes position difference and rotation angle difference between the two calibration targets included in the first and second birds-eye view images. The storing control section stores the orientation parameter in storage.
