The present invention relates to an apparatus and method for providing information about curvature of a road. The purpose of the present invention is to provide information about a curvature by determining the curvature through recognizing road signs deployed along a curved road. The apparatus according to the present invention includes: a template matching unit which extracts a template of a road sign stored in advance, and matches the template of the road sign to an image obtained from a camera for capturing an image for the curved road in front of a vehicle; a sign recognizing unit for recognizing, when a plurality of images matched to the template of the road sign are detected in the image, the road sign in front of the vehicle from the plurality of detected images; and a curvature determining unit which compares the sizes of a plurality of images corresponding to the road sign recognized from the image, and determines the curvature of the curved road depending on changes in the sizes of the plurality of images.

    본 발명은 도로 곡률 안내 장치 및 방법에 관한 것이다. 본 발명에 따른 장치는, 미리 저장된 도로표지판의 탬플릿을 추출하여 차량 전방의 곡선도로에 대한 영상을 촬영하는 카메라로부터 취득한 영상과 상기 도로표지판의 탬플릿을 매칭하는 탬플릿 매칭부, 상기 영상 내에서 상기 도로표지판의 탬플릿과 매칭되는 복수의 이미지가 검출되면, 상기 검출된 복수의 이미지로부터 차량 전방에 위치한 도로표지판을 인식하는 표지판 인식부, 및 상기 영상으로부터 인식된 도로표지판에 대응하는 복수의 이미지에 대한 크기를 비교하여 상기 복수의 이미지의 크기 변화에 따라 상기 곡선도로에 대한 곡률을 판단하는 곡률 판단부를 포함한다.
