To propose a technology capable of determining a train position from a photographed image without providing a special marker.SOLUTION: In a train position determination device 2, overhead cameras 21 and 23 are installed at overhead positions at which an end part of a linear shadow generated in an opening between a terminal vehicle being a head vehicle 11 or a rearmost vehicle 13 of a train 1 and a platform in the linear shadow generated in an opening between the train 1 and the platform is included in a photographic range when the train 1 stops at a home position of a station. On the other hand, a processing device 200 determines whether the linear shadow is included in a photographed images of the overhead cameras 21 and 23. Then, it determines a relative position of the train 1 with respect to the home position on the basis of the position of the end part of the linear shadow when the determination indicates an affirmative determination.SELECTED DRAWING: Figure 1
【課題】特別なマーカーを設けることなく撮影画像から列車位置を判定することを可能とする技術を提案すること。【解決手段】列車位置判定装置2において、俯瞰カメラ21,23は、駅の定位置に列車1が停止した場合に、列車1とプラットホームとの隙間に生じる線状陰影のうち、列車1の先頭車両11又は最後尾車両13である末端車両とプラットホームとの隙間に生じる当該線状陰影の末端部が撮影範囲に含まれる俯瞰位置に設置される。一方、処理装置200は、俯瞰カメラ21,23の撮影画像に線状陰影が含まれているか否かを判定する。そして、当該判定が肯定判定された場合に、その線状陰影の末端部の位置に基づいて、定位置に対する列車1の相対位置を判定する。【選択図】図1
