System and method for navigation assistance
First Claim
1. A method for navigation correction assistance, the method comprising:
- providing a vehicle with a camera and an autonomous navigation system comprising a processor, a non-transitory memory, a visual navigation buoy database stored in the memory, and a navigation application enabled as a sequence of processor executable instructions stored in the memory for autonomously navigating;
the navigation application visually acquiring a first visual navigation buoy with an identity marker;
accessing the navigation buoy database to cross-reference the first navigation buoy identity marker to a first spatial position;
visually acquiring a first direction marker on the first navigation buoy; and
,in response to visually acquiring the first direction marker, determining a first angle between the camera and the first spatial position.

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.
