Abstract
PURPOSE:To discriminate move complicated vehicle classifications by providing a vehicle classification code recognizing part and a plate color discriminating part besides a plate size discriminating part which discriminates the size of a plate. CONSTITUTION:A plate position discriminating part 16 which discriminates the position of a plate part in accordance with image information of an image memory 10 to take out plate information like a black-and-white histogram of the plate, a plate size discriminating part 17 which discriminates the size of the plate based on information of the plate position discriminating part 16, and a plate color discriminating part 18 which discriminate black or white of the plate based on information of the plate position discriminating part 16 are provided. A vehicle classification code recognizing part 19 which compares a binary pattern of the vehicle classification code obtained from the plate position discriminating part 16 with binary patterns stored in a recognition dictionary part 20 to recognize the vehicle classification code and an overall discriminating part 21 which synthesizes said discrimination results and sends them to a pass vender 15 are provided. Thus, the vehicle classification device is obtained which can be used for a pass issuing machine which issues a pass in accordance with the vehicle classification based on not only size discrimination.
