To provide a method by which an abnormality of a blockade machine is accurately detected by means of properly extracting a shutdown rod part from an image of a photographed shutdown rod.SOLUTION: An abnormality monitoring device 10 monitors an abnormality of a shutdown machine based on a shutdown rod image which is an image of the shutdown rod photographed by a camera 3 installed in a railroad crossing. The shutdown rod is constituted of a rod with distributed prescribed marker color bands accompanied by prescribed intervals along the longitudinal length. The abnormality monitoring device 10 has a detection picture image generation unit 141 to generate detection pictures with mask processing for masking parts other than marker color components from shutdown rod pictures, and an abnormality detection unit 143 to detect an abnormality of the shutdown machine based on picture parts corresponding to the marker color in the detection picture image.SELECTED DRAWING: Figure 9 【課題】遮断かんを撮影した画像から遮断かんの部分を適正に抽出して、遮断機の異常を精度よく検出すること。【解決手段】異常監視装置１０は、踏切に設置されたカメラ３によって撮影された遮断かんの画像である遮断かん画像に基づいて、遮断機の異常を監視する。遮断かんは、長手方向に沿って所定のマーカ色が所定の間隔で配色されて構成されている。異常監視装置１０は、遮断かん画像からマーカ色の色成分以外をマスクするマスク処理を行って検出用画像を生成する検出用画像生成部１４１と、検出用画像中のマーカ色に対応する画像部分に基づいて、遮断機の異常を検出する異常検出部１４３と、を備える。【選択図】図９
