DOOR OPENING/CLOSING DETECTION SYSTEM
To provide a structure capable of detecting an opening/closing state of a door of a moving body by using the presence/absence of change in the depth of an overlapped imaging range.SOLUTION: A plurality of cameras 30 (30a, 30b, 30c) respectively imaging a vehicle door 12 in a closed state of a railway vehicle 10, which is stopped at a target stop position, are respectively disposed such that a QR code 50 of the vehicle door 12 is included in the overlapped imaging ranges S1, S2 whose imaging visual fields are partly overlapped with each other. The control device 40 detects the opening/closing state of the vehicle door 12 based on the change in the depth in the overlapped imaging ranges S1, S2, which are obtained from the parallax D in captured images from the two cameras having captured the overlapped imaging ranges S1, S2 as imaging results of the respective cameras 30.SELECTED DRAWING: Figure 11
【課題】重複撮像範囲での奥行きの変化の有無を利用することで移動体の扉の開閉状態を検知可能な構成を提供する。【解決手段】目標停車位置に停止した鉄道車両１０の閉状態の車両ドア１２をそれぞれ撮像する複数のカメラ３０（３０ａ，３０ｂ，３０ｃ）は、一部の撮像視野が重なる重複撮像範囲Ｓ１，Ｓ２に車両ドア１２のＱＲコード５０が含まれるようにそれぞれ配置される。制御装置４０は、各カメラ３０の撮像結果として、重複撮像範囲Ｓ１，Ｓ２を撮像した２つのカメラの撮像画像での視差Ｄから求められる重複撮像範囲Ｓ１，Ｓ２での奥行き変化に基づいて、車両ドア１２の開閉状態を検知する。【選択図】図１１
