Provided are an apparatus and a method for monitoring a pantograph of an electric railway vehicle. According to the present invention, a pantograph image obtained by capturing a pantograph is collected, and is compared to a preset pantograph template image to detect a pantograph object for each image frame, and a tilt angle and displacement of a current collecting plate is measured from the detected pantograph objects to detect preset vibration characteristics. Also, the detected vibration characteristics are classified through a classifier which machine-learns the detected vibration characteristics of the pantograph image, and vibration characteristics are classified through the classifier which machine-learns the vibration characteristics of the pantograph image detected before identifying normal and abnormal states of a pantograph, thereby identifying the normal and abnormal states of the pantograph. Also, a pantograph search area of a next image frame is set based on a pantograph object detection result of a previous image frame when the pantograph object is detected.

    전기철도차량 팬터그래프 모니터링 장치 및 방법을 제공하며, 팬터그래프를 촬영한 팬터그래프 영상을 수집하고, 팬터그래프 영상을 기설정된 팬터그래프 템플릿 영상과 비교하여 영상 프레임 별로 팬터그래프 객체를 검출하고, 검출된 팬터그래프 객체들로부터 집전판의 경사 각도 및 변위를 측정하여 기설정된 진동 특성들을 검출하며, 이전에 검출된 팬터그래프 영상의 진동 특성들을 기계학습한 분류기를 통해 상기 검출된 진동 특성을 분류하여 팬터그래프의 정상 상태 및 비정상 상태를 식별이전에 검출된 팬터그래프 영상의 진동 특성들을 기계학습한 분류기를 통해 진동 특성들을 분류하여 팬터그래프의 정상 상태 및 비정상 상태를 식별하되, 팬터그래프 객체 검출 시 이전 영상 프레임의 팬터그래프 객체 검출 결과에 기초하여 다음 영상 프레임의 팬터그래프 탐색 영역을 설정한다.
