Abstract:
The purpose of the present invention is to easily and correctly confirm the results of calibration of a camera parameter used to generate an overhead view video. A vehicle-mounted device 16 includes: a video acquisition unit 21 for acquiring a video around a vehicle 1 from a camera 11; a light emission control unit 25 for controlling light emission of a light beam pattern by a light emission device 14 which irradiates, with the light beam pattern, the ground or a floor surface in a predetermined position with respect to the vehicle 1; an image processing unit 24 for generating an overhead view video including the light beam pattern, using the video acquired by the video acquisition unit 21; a superposed image generation unit 26 for generating a superposed image with respect to a position corresponding to the light beam pattern included in the overhead view video; and an image determination processing unit 27 for determining, by detecting an overlapping portion of a line and an image of the light beam pattern in the overhead view video on which the superposed image is superposed, whether a camera parameter for generating the overhead view video is correctly calibrated or not.
