The present invention relates to an apparatus to correct distortion of a top view image and a method thereof. For the same, the method to correct distortion as to the top view image generated through a camera mounted on a vehicle includes the steps of: acquiring a photographing image photographed through the camera; generating the top view image on the basis of the photographing image, and detecting a traffic lane in the top view image; obtaining height of the camera by calculating distance between the camera and a bottom floor; and converting a scale of the top view image, on the basis of a ratio between the height of the camera and reference height. The apparatus of the present invention can solve distortion of an image due to variation of vehicle height, when an around view or the top view is generated.
본 발명은 탑뷰 영상 왜곡 보정 장치 및 방법에 관한 것이다. 이를 위한 본 발명의 차량에 장착된 카메라를 통해 생성된 탑뷰 이미지에 대한 왜곡 보정 방법은 카메라를 통해 촬영된 촬영 이미지를 취득하는 단계; 촬영 이미지를 근거로 탑뷰 이미지를 생성하고, 탑뷰 이미지에서 차선을 검출하는 단계; 카메라와 바닥면 사이의 거리를 계산함으로써 카메라의 높이를 도출하는 단계; 및 카메라의 높이와 기준 높이의 비율을 근거로, 탑뷰 이미지의 스케일을 변환하는 단계를 포함하는 것을 특징으로 한다.
