To enable minute discrimination of a vehicle type of a vehicle with a simple configuration without using a sensor other than a camera.SOLUTION: A vehicle type discrimination device 10 includes a vehicle type narrowing-down section 21 and a vehicle type discrimination section 22. The vehicle type narrowing-down section 21 narrows down a vehicle type of a vehicle from information such as a number indicated by a license plate of the vehicle and a combination of a background color with a character color on the license plate. The vehicle type discrimination section 22 minutely discriminates the vehicle type among the vehicle types narrowed-down by the narrowing-down section 21 with image data of the vehicle as an input.SELECTED DRAWING: Figure 1
【課題】カメラ以外の他のセンサを用いない簡便な構成により、車両の車型を細かく判別可能にする。【解決手段】車型判別装置10は、車型絞込部21と車型判別部22とを備える。車型絞込部21は、車両のナンバープレートが示すナンバーとナンバープレートの背景色及び文字色の組合せといった情報から車両の車型を絞り込む。車型判別部22は、車両の画像データを入力として、絞込部21によって絞り込まれた車型のうち、さらに細かくどの車型であるかを判別する。【選択図】図1
