The present invention relates to an apparatus for correcting a camera for a vehicle, including: an image processor processing a front image captured by a front camera; a light source tracker detecting a light source from the front image and collecting location information of the light source from each frame of the front image; and a vanishing point estimator determining the movement pattern of the light source based on the location information collected by the light source tracker, and tracking a vanishing point in accordance with the movement pattern. Accordingly, even though the physical location of the front camera can be changed, or the vanishing point is changed due to the front of the vehicle being lifted or descended by a passenger or freight, the present invention can precisely calculate a distance to an object captured in the front image.

    본 발명은 차량용 카메라 보정 장치에 관한 것으로서, 전방 카메라에서 촬영된 전방 영상을 처리하는 영상처리부; 전방 영상에서 광원을 검출하고, 전방 영상의 각 프레임에서 광원의 위치 정보를 수집하는 광원추적부; 광원추적부에서 수집한 위치 정보에 기초하여 광원의 이동 패턴을 파악하고, 이동 패턴에 따라 소실점을 추정하는 소실점 추정부;를 포함한다. 이에 의해, 전방 카메라의 물리적 위치가 변경되거나, 탑승자나 화물에 의해 차량의 전방이 들리거나 내려가서 소실점이 변경되더라도 전방 영상에 촬영된 물체와의 거리를 정확히 산출할 수 있다.
