본 발명은 후측방 접근차량 경고 시스템 및 방법에 관한 것이다. 또한, 본 발명은 후방 카메라에서 촬영된 원본 영상 프레임에서 녹화 영상으로 저장할 영역을 제외한 주변 영역이 크로핑되면, 크로핑된 주변 영역의 영상을 블라인드 스팟 영상으로 수집하는 수집부와, 블라인드 스팟 영상에서 차량의 후측방에 대응하는 위치에 관심 영역을 설정하고, 해당 관심 영역 내에서 접근차량이 존재하는지 검출하며, 검출된 접근차량이 차지하는 면적의 비율에 따라 접근차량의 위험도를 분석하는 제어부와, 제어부의 제어하에 접근차량의 검출 여부와 위험도에 따른 경고 신호를 출력하는 경고 출력부를 구비함으로써, 후방 카메라의 원본 영상에서 크로핑되어 버려지는 블라인드 스팟 영상을 이용하여 후측방의 접근차량을 검출하고 위험도를 분석할 수 있다.

    The present invention relates to a rear side approaching vehicle warning system and method. According to the present invention, the rear side approaching vehicle warning system comprises: a collection unit collecting an image of a cropped surrounding area as a blind spot image when a surrounding area excluding an area to be saved as a recorded image is cropped in an original video frame captured by a rear camera; a control unit setting an area of interest corresponding to the rear side of a vehicle in the blind spot image, detecting whether an approaching vehicle exists within the area of interest, and analyzing the risk of the approaching vehicle according to the ratio of the area occupied by the detected approaching vehicle; and a warning output unit outputting a warning signal according to whether the approaching vehicle is detected and the level of risk under the control of the control unit. Accordingly, the rear side approaching vehicle warning system uses the blind spot image which is cropped and discarded from the original image of the rear camera to detect rear side approaching vehicles and analyze the degree of risk.
