PROBLEM TO BE SOLVED: To provide a vehicle model discrimination system capable of discriminating a vehicle model category in detail and being installed in a place in which a sufficient installation space cannot be preserved.SOLUTION: A vehicle model discrimination system 1A includes plural floodlight projectors S1 that project light rays, plural light receivers S2 that are arranged in association with the floodlight projectors S1 and can receive light rays P, an intercepted area acquisition unit 110 that receives input of a detection signal signifying whether the light receivers S2 have received the light rays P, and acquires an intercepted area, which is occupied by the light receiver S2 associated with the intercepted light ray P, from among areas in which the respective light receivers S2 are arranged, and a vehicle model discrimination unit 111 that acquires a vehicle body silhouette which is two-dimensional information obtained by juxtaposing on a time base plural intercepted areas acquired at different times, and discriminates a vehicle model category, to which the vehicle belongs, on the basis of the vehicle body silhouette and reference patterns classified into vehicle model categories.SELECTED DRAWING: Figure 2
【課題】十分な設置スペースを確保できない場所にも設置可能で、かつ、車種区分を詳細に判別可能な車種判別装置を提供する。【解決手段】車種判別装置1Aは、光線を投光する複数の投光部S1と、複数の投光部S1の各々と対応して配置され、光線Pを受光可能な複数の受光部S2と、複数の受光部S2における光線Pの受光の有無を示す検出信号の入力を受け付けて、複数の受光部S2が配置された領域のうち遮光されている光線Pに対応する受光部S2が占める遮光領域を取得する遮光領域取得部110と、異なる時刻に取得された複数の遮光領域を時間軸上に並べて得られる二次元情報である車体シルエットを取得し、当該車体シルエットと車種区分別に分類された参照パターンとに基づいて、車両が属する車種区分を判別する車種判別部111と、を備えている。【選択図】図2
