The present invention relates to a rear collision alert system of a vehicle. More specifically, according to the present invention, the rear collision alert system of a vehicle comprises: an image detection unit which acquires a rear image of the vehicle; an image resolution correction unit which corrects a resolution of the rear image acquired by the image detection unit; a vehicle determination unit which determines if an object in the image acquired by the image detection unit is a vehicle on a rear side; a distance/speed calculation unit which, when the object is determined as a vehicle on a rear side by the vehicle determination unit, calculates the distance from the vehicle on a rear side and the speed of the vehicle on a rear side; and an output unit which outputs a certain warning to the driver. The image detection unit includes a stereo camera which acquires two or more images at the same time, thereby allowing the vehicle to drive safely.

    본 발명은 차량의 후방 추돌경보시스템에 관한 것으로서, 특히, 자기 차량의 후방 영상을 획득하는 영상 감지부와, 상기 영상 감지부에 의하여 획득된 상기 후방 영상의 화질을 보정하는 영상화질 보정부와, 상기 영상 감지부에 의하여 획득된 영상의 물체가 후방 차량인지 여부를 판정하는 차량 판단부와, 상기 차량 판단부에 의하여 상기 물체가 상기 후방 차량으로 판정된 경우 상기 후방 차량과 상기 자기 차량 사이의 거리 및 상기 후방 차량의 속도를 계산하는 거리/속도 연산부와, 상기 운전자에게 소정의 경고를 출력하는 출력부를 포함하고, 상기 영상 감지부는, 동시에 적어도 2개의 영상 이미지를 획득하는 스테레오 카메라로 구성됨으로써, 안전 주행이 가능하도록 하는 이점을 제공한다.
