To make it possible to detect abnormality and the like of route environment based on a camera image obtained by photographing a periphery of a train during the traveling of the train with the use of a camera installed for the purpose of detecting the pinching of a passenger or a stuff at a door.SOLUTION: A route environment monitoring system includes a camera 1 provided corresponding to a door for getting on/off of passengers of a train, an image analysis server 2 for detecting abnormality of route environment based on a camera image photographed by the camera and generating alarm information, and a notification device 3 and a monitoring terminal 6 acquiring the alarm information and notifying an attendant of an occurrence state of the abnormality in the route environment. The image analysis server detects the pinching of a passenger or a stuff at the door based on the camera image to generate alarm information about the pinching at the door in a first monitoring mode. The image analysis server detects the abnormality of the route environment based on the camera image to generate alarm information about the abnormality of the route environment in a second monitoring mode. The first monitoring mode and the second monitoring mode are switched by determining whether a train is in a stop state or a moving state.SELECTED DRAWING: Figure 1

    【課題】ドアの挟み込みを検知する用途で設置されたカメラを利用して、列車の走行中に列車の周辺を撮影して取得したカメラ画像に基づいて路線環境の異常等を検知できるようにする。【解決手段】列車における人物乗降用のドアに対応して設けられたカメラ1と、カメラにより撮影されたカメラ画像に基づいて路線環境の異常を検知して発報情報を生成する画像解析サーバ2と、発報情報を取得して、路線環境の異常の発生状況を係員に報知する報知装置3および監視端末6と、を備え、画像解析サーバは、第1の監視モードにおいて、カメラ画像に基づいてドアの挟み込みを検知して、ドアの挟み込みに関する発報情報を生成し、第2の監視モードにおいて、カメラ画像に基づいて路線環境の異常を検知して、路線環境の異常に関する発報情報を生成し、列車が停止状態か移動状態かを判別して第1の監視モードと第2の監視モードとを切り換える。【選択図】図1
