The present invention relates to an apparatus for correcting a GPS location signal of an autonomous vehicle by using road surface image information obtained during driving. According to the present invention, the autonomous vehicle corrects the GPS vehicle location signal which is inevitably affected by a slope of the driving road to be suitable for the position of the vehicle. Therefore, the vehicle location is accurately recognized during autonomous driving and an accident is prevented as the apparatus responses to surrounding environmental information without error. The location signal correction apparatus comprises a camera, a road surface slope measurement unit, and a GPS location signal correction unit.
본 발명은 주행 중 취득되는 노면의 영상정보를 이용하여 자율주행 차량의 GPS 위치 신호를 보정하는 장치이다. 본 발명에 따르면 자율주행 차량은 주행하는 노면의 경사각으로 인한 필연적으로 발생하는 GPS 차량 위치신호를 차량의 위치에 맞게 보정할 수 있다. 따라서, 자율 주행 시 보다 정확한 차량위치를 인지할 수 있어, 주변의 환경정보에 오류 없이 대응하여 사고 등을 예방할 수 있다.
