An around view monitoring system and a camera tolerance correction method are disclosed. The around view monitoring system includes: a camera unit including a plurality of cameras mounted to photograph each of the front, the right, the left, and rear of a vehicle; a tolerance correction unit that determines whether there is a distortion according to a predetermined criterion in an individual top view image corresponding to the captured image photographed by each camera, and updates a conversion rule for converting the captured image into the individual top view image if the distortion exists; and an image synthesizer that generates an AVM image by using the updated conversion rule and a plurality of captured images captured by the camera unit.

    어라운드 뷰 모니터링 시스템 및 카메라 공차 보정 방법이 개시된다. 어라운드 뷰 모니터링 시스템은 차량의 전방, 우측면, 좌측면 및 후방 각각을 촬영하도록 장착된 복수의 카메라를 포함하는 카메라 유닛; 각 카메라에서 촬영된 촬영 영상에 상응하는 개별 탑뷰 영상에서 미리 지정된 기준에 따른 틀어짐이 존재하는지 여부를 판단하고, 틀어짐이 존재하면 촬영 영상을 개별 탑뷰 영상으로 변환하는 변환 규칙을 갱신하는 공차 보정 유닛; 및 상기 갱신된 변환 규칙과 상기 카메라 유닛에서 촬영된 복수의 촬영 영상을 이용하여 AVM 영상을 생성하는 영상 합성부를 포함한다.
