To propose a technology excelling in maintenance property without any danger of contact with a train as a technology regarding setting for photography such as calibration when determining a relative position of the train to a home position in a station using an image photographed by a camera.SOLUTION: A camera 20 is installed in a station for picturing a train stopping at a home position in the station from the side in a train position determination device. In addition, a processor 200 includes: an image processing unit 242 for carrying out image processing of converting a pictured image pictured by the camera 20 into a side view image viewing the train from the side containing distortion compensation; and a train position determination unit 243 for determining a relative position of the train to the home position by comparing the position with a prescribed portion of the train pictured in the side view image when the train is stopping at the home position and the position in the side view image of the prescribed portion pictured in the side view image which is image processed by the image processing unit 242.SELECTED DRAWING: Figure 6

    【課題】カメラで撮影した画像を用いて駅の定位置に対する列車の相対位置を判定する場合のキャリブレーション等の撮影用の設定に係る技術として、触車の危険性がなく、メンテナンス性に優れた技術を提案すること。【解決手段】列車位置判定装置において、カメラ20は、駅の定位置に停止する列車を側方から撮影するために当該駅に設置される。そして、処理装置200は、カメラ20が撮影した撮影画像について、歪み補正を含む当該列車を側面視した側面視画像に変換する画像処理を行う画像処理部242と、定位置に停止している列車を撮影した場合に当該列車の所定部位が側面視画像中に写る位置と、画像処理部242によって画像処理された側面視画像中に写っている所定部位の当該側面視画像中の位置とを比較して定位置に対する列車の相対位置を判定する列車位置判定部243と、を備える。【選択図】図6
