A method for calibrating a camera for a vehicle according to an embodiment comprises the steps of: acquiring attitude angle information of a vehicle by using a traveling direction of a vehicle, which is obtained on the basis of a satellite signal, and a vertical direction of the surface of the ground, which is obtained on the basis of a precise map; acquiring attitude angle information of a camera of the vehicle by matching the precise map to an image obtained by the camera; and acquiring coordinate system transformation information between the vehicle and the camera by using the attitude angle information of the vehicle and the attitude angle information of the camera.

    Un mode de réalisation de l'invention concerne un procédé d'étalonnage d'une caméra d'un véhicule consistant : à acquérir des informations d'angle d'attitude d'un véhicule à l'aide d'une direction de déplacement d'un véhicule, obtenue en fonction d'un signal satellite, et d'une direction verticale de la surface du sol, obtenue en fonction d'une carte précise ; à acquérir des informations d'angle d'attitude d'une caméra du véhicule par la mise en correspondance de la carte précise avec une image obtenue par la caméra ; et à acquérir des informations de transformation de système de coordonnées entre le véhicule et la caméra à l'aide des informations d'angle d'attitude du véhicule et des informations d'angle d'attitude de la caméra.

    일 실시예에 따른 차량용 카메라 캘리브레이션 방법은 위성 신호를 기초로 획득된 차량의 진행 방향과 정밀 지도를 기초로 획득된 지면의 수직 방향을 이용하여 차량의 자세각 정보를 획득하는 단계; 상기 차량의 카메라에 의해 획득된 영상에 상기 정밀 지도를 매칭하여 카메라의 자세각 정보를 획득하는 단계; 및 상기 차량의 자세각 정보 및 상기 카메라의 자세각 정보를 이용하여 상기 차량 및 상기 카메라 간 좌표계 변환 정보를 획득하는 단계를 포함한다.
