Abstract
A system and method are provided for navigation correction assistance. The method provides a vehicle with a camera and an autonomous navigation system comprising a navigation buoy database and a navigation application. The navigation application visually acquires a first navigation buoy with an identity marker and accesses the navigation buoy database, which cross-references the first navigation buoy identity marker to a first spatial position. A first direction marker on the first navigation buoy is also visually acquired. In response to visually acquiring the first direction marker, a first angle is determined between the camera and the first spatial position. A first distance may also be determined between the vehicle and the first navigation buoy using visual methods or auxiliary position or distance measurement devices. Then, in response to the first spatial position, the first angle, and the first distance, the spatial position of the vehicle can be calculated using trigonometry.
