Abstract
A method for calibrating vehicle cameras is simplified by providing painted patterns on a road surface and by capturing those patterns by the cameras to be calibrated. According to a predefined positional relationship of the cameras with the painted patterns, captured images of the painted patterns are bird's-eye converted and matched with reference to calculate camera positions in a vehicle, thereby enabling an automatic calibration of camera directions and the like.
