The present invention relates to a safe operation assistance device of a railway vehicle, and more particularly, to a safe operation assistance device of a railway vehicle configured to extract the number of frames of a forward recognition image, used in recognizing a sign located in the traveling direction of a railway vehicle, in proportion to the speed of the railway vehicle, thereby accurately recognizing the sign with a small calculation amount. The sign located in the traveling direction of the railway vehicle is configured to set a search area for searching the sign in a forward image according to a rule of the sign being located at an upper end or on a right side of the forward image, and accordingly can recognize the sign accurately and quickly even on a fast moving railway vehicle.

    본 발명은 철도 처량의 안전 운행 보조 장치에 관한 것으로, 보다 구체적으로 철도 차량의 진행 방향에 위치하는 표지판을 인식하는데 사용되는 전방 인식 이미지의 프레임 수를 철도 차량의 속도에 비례하여 추출함으로써 적은 연산량으로 정확하게 표지판을 인식할 수 있고, 철도 차량의 진행 방향에 위치하는 표지판은 전방 이미지의 상단 또는 우측에 위치한다는 규칙에 따라 전방 이미지에서 표지판을 탐색하는 탐색 영역을 설정함으로써 빠르게 이동하는 철도 차량에서도 정확하고 빠르게 표지판을 인식할 수 있는 철도 차량의 안전 운행 보조 장치에 관한 것이다.
