To identify a rail track on which a railway vehicle travels among a plurality of rail tracks when the plurality of rail tracks on which the railway vehicle may travel are detected from a photographic image that is obtained by photographing a region in a traveling direction of the railway vehicle.SOLUTION: In a vehicle system 100, a rail track detection device 2 includes an image acquisition unit 21 acquiring a photographic image that is obtained by photographing a region in a traveling direction of a railway vehicle during traveling, a rail track detection unit 23 detecting a rail track in the photographed image, a branch detection unit 24 detecting a branch of the rail track in the photographed image, and a traveling rail track identification unit 25 identifying a rail track on which the railway vehicle travels among a plurality of rail tracks ahead of the branch on which the railway vehicle may travel based on an image area including the branch in the photographic image.SELECTED DRAWING: Figure 2

    【課題】鉄道車両の進行方向の領域を撮影した撮影画像から鉄道車両が進行する可能性のある複数の線路を検出した場合に、その複数の線路のうち鉄道車両が進行する線路を識別する。【解決手段】車両システム100において、線路検出装置2は、走行中の鉄道車両の進行方向の領域を撮影することで得られる撮影画像を取得する画像取得部21と、前記撮影画像において線路を検出する線路検出部23と、前記撮影画像において前記線路の分岐を検出する分岐検出部24と、前記撮影画像における前記分岐を含む画像領域に基いて、前記分岐の先の前記鉄道車両が進行する可能性のある複数の線路のうち前記鉄道車両が進行する線路を識別する進行線路識別部25と、を備える。【選択図】図2
