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.

Abstract: Feature detection may be performed on an image. After feature descriptors for each detected feature are computed, feature matching between feature descriptors for the current image and for a key image frame is performed. If a sufficient number of good matches are identified, key points associated with the feature correspondences may be projected from image coordinates to world coordinates. A distance, in the world coordinate frame, between each feature correspondence may he computed. When the computed distances indicate sufficient movement of the mobile agent to ensure accurate motion estimation, a motion estimate may he computed from the pairs of world coordinates associated with the feature correspondences. A current camera pose in a global coordinate frame may be generated. A motion trajectory may then be determined and feature descriptors for the key image may be updated to the feature descriptors for the current image frame.

A navigation application stores a vehicle pose (history of vehicle position). The application detects a plurality of matching feature points in a first matching image pair, and determines a plurality of corresponding object points in three-dimensional (3D) space from the first image pair. A plurality of feature points are tracked from the first image pair to a second image pair, and the plurality of corresponding object points in 3D space are determined from the second image pair. From this, a vehicle pose transformation is calculated using the object points from the first and second image pairs. The rotation angle and translation are determined from the vehicle pose transformation. If the rotation angle or translation exceed a minimum threshold, the stored vehicle pose is updated.
