The present invention provides a system for calibrating the slope of a road, comprising: a camera installed in a vehicle and taking a front image of the vehicle; a lane recognizing unit recognizing a lane on which the vehicle is driving and an expected road on which the vehicle is expected to drive from the front image taken by the camera; a slope estimation unit estimating the slope of the expected road on which the vehicle is expected to drive based on the lane of the driving road and the lane of the expected road recognized by the lane recognizing unit; an acceleration sensor detecting the slope of the vehicle; a slope input unit receiving the slope of the driving road from the acceleration sensor or the slope of the expected road from the outside; and a calibration unit adjusting a parameter for calibrating the front image taken by the camera based on the slope input from the slope input unit and the slope of the expected road estimated by the slope estimation unit. The present invention can definitely recognize the lane.

    본 발명에 따르면 차량에 설치되고, 차량의 전방 영상을 촬영하는 카메라; 카메라에서 촬영한 전방 영상으로부터 차량이 주행 중인 주행도로의 차선 및 주행이 예상되는 예상도로의 차선을 인식하는 차선인식부; 차선인식부에서 인식한 주행도로의 차선 및 예상도로의 차선을 기반으로 차량의 주행이 예상되는 예상도로의 경사도를 추정하는 경사도추정부; 차량의 기울기를 감지하는 가속도 센서; 가속도 센서로부터 주행도로의 경사도를 입력받거나 또는 외부로부터 예상도로의 경사도를 수신하는 경사도 입력부; 및 경사도 입력부에서 입력된 경사도 및 경사도추정부에서 추정한 예상도로의 경사도를 기반으로 카메라에서 촬영한 전방 영상을 보정하는 파라미터를 조정하는 캘리브레이션부;를 포함하는 도로의 경사도 보정 시스템이 소개된다.
