A vehicle device is provided to easily and accurately check a calibration result of camera parameters used for generating an bird's-eye view video. A vehicle device includes a video acquisition unit 21 configured to acquire videos captured by cameras configured to capture surroundings of a vehicle 1; a light emission controller 25 configured to control light emission of a light beam pattern which is emitted by light emitting devices 14 and with which the ground or a floor surface is irradiated at certain positions with respect to the vehicle 1; an image processing unit 24 configured to generate, using the videos acquired by the video acquisition unit 21, a bird's-eye view video including the light beam pattern; a superimposing image generation unit 26 configured to generate a superimposing image at a position corresponding to the light beam pattern included in the bird's-eye view video; and an image determination processing unit 27 configured to detect, in the bird's-eye view video on which the superimposing image is superimposed, an overlapping portion of a line and an image of the light beam pattern and determine whether camera parameters for generating the bird's-eye view video are accurately calibrated.
