탑-뷰 영상 생성 장치 및 그 방법을 개시한다. 본 발명의 일 측면에 의하면, 차량에 설치된 전후좌우 카메라로부터 전후좌우 영상을 각각 획득하는 과정; 상기 전후좌우 영상으로부터 상기 차량의 좌측 차선과 우측 차선을 검출하는 과정; 상기 좌측 차선과 상기 우측 차선이 탑-뷰(Top view) 영상 좌표계에서 요구되는 기하학적 조건을 만족하도록 전후좌우 카메라 각각의 카메라 자세각을 추정하는 과정; 및 상기 카메라 자세각으로 구성된 회전행렬을 기반으로 상기 전후좌우 영상을 회전변환하여, 전후좌우 탑-뷰 영상을 생성하고, 생성된 전후좌우 탑-뷰 영상을 합성하여, 하나의 최종 탑-뷰 영상을 생성하는 과정을 포함하는 탑-뷰 영상 생성 방법을 제공한다.

    Disclosed are a top-view image generation device capable of compensating for camera tolerance while driving a vehicle to improve consistency of an around-view image and a method thereof. According to one aspect of the present invention, the method of the top-view image generation device comprises the processes of: acquiring front, rear, left, and right images respectively from front, rear, left, and right cameras installed in a vehicle; detecting left and right lanes of the vehicle from the front, rear, left, and right images; estimating a camera position angle of each of the front, rear, left, and right cameras so that the left lane and the right lane satisfy a geometrical condition required in a top view image coordinate system; and rotating the front, rear, left, and right images based on a rotation matrix composed of a camera position angle to generate front, rear, left, and right top-view images and synthesize the front, rear, left, and right top-view images to generate a final top-view image.
