The present invention relates to a device for correcting a GPS position signal of an autonomous vehicle by using road surface image information acquired during driving. According to the present invention, an autonomous vehicle can correct a GPS vehicle position signal, which is inevitably generated due to an inclination angle of a road surface on which the vehicle drives, to be suitable for the position of the vehicle. Accordingly, it is possible to recognize a more accurate vehicle position during autonomous driving, and thus prevent an accident and the like by responding to surrounding environment information without an error.

    La présente invention concerne un dispositif pour corriger un signal de position de système mondial de localisation (GPS) d'un véhicule autonome en utilisant des informations d'image de surface de roulement acquises pendant la conduite. Selon la présente invention, un véhicule autonome peut corriger un signal de position de véhicule GPS, qui est inévitablement généré en raison d'un angle d'inclinaison d'une surface de roulement sur laquelle le véhicule roule, pour qu'il soit adapté à la position du véhicule. Par conséquent, il est possible de reconnaître une position de véhicule plus précise pendant la conduite autonome, et ainsi d'empêcher un accident et similaire en répondant à des informations de milieu environnant sans erreur.

    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.
