Abstract

An apparatus and method for visual localization of a visual camera system outputting real-time visual camera data and a graphics processing unit receiving the real-time visual camera data. The graphics processing unit accesses a database of prior map information and generates a synthetic image that is then compared to the real-time visual camera data to determine corrected position data. The graphics processing unit determines a camera position based on the corrected position data. A corrective system for applying navigation of the vehicle based on the determined camera position can be used in some embodiments.
