To provide a method which detects an operation of opening or closing the door of a railroad vehicle.SOLUTION: A device 100 to detect open or close state of a vehicle door is installed in a station to detect open or close state of a door 11 of a railroad vehicle 1 that stops at a prescribed position. In this device 100 to detect open or close state of a vehicle door, an imaging apparatus 20 images a door 11 which is in closed state of the railroad vehicle 1, that stops at the prescribed position and a recurrent reflector (a reference reflector and a door reflector) arranged at a vehicle body side wall part in a neighborhood of the door. And a processor 30 discriminates picture locations of the reference reflector and the door reflector in the picture imaged with imaging apparatus 20, depending on referencing a physical relationship of the reference reflector and the door reflector and detects open or close state of the vehicle door 11.SELECTED DRAWING: Figure 1
【課題】鉄道車両の車両扉の開扉動作及び閉扉動作を検知すること。【解決手段】車両扉開閉検知装置100は、所定位置に停止した鉄道車両1の車両扉11の開閉を検知するために駅に設置される。この車両扉開閉検知装置100において、撮影装置20は、所定位置に停止した閉扉状態の鉄道車両1の車両扉11及びその近傍の車体側壁部に設けられた再帰性反射体(基準反射体及び扉反射体)を撮影する。そして、処理装置30は、基準反射体及び扉反射体の位置関係を参照して撮影装置20による撮影画像中の基準反射体及び扉反射体の画像箇所を判別し、車両扉11の開閉を検知する。【選択図】図1
