VISUAL GUIDANCE METHOD FOR IMPROVING AUTONOMOUS NAVIGATION WITH ROW FOLLOWING CORRECTIONS IN STEREO CAMERA SYSTEMS

Systems and methods related to visual guidance for improving autonomous navigation with row following corrections in stereo camera systems are disclosed herein. A visual positioning system may implement a method for navigating a vehicle. The method may comprise: receiving navigation coordinates defining a route comprising a straight path; detecting detected lines that are parallel to the straight path based on images received from at least one camera on the vehicle; accessing ground truth data; deriving vehicle coordinates from the ground truth data; determining a centerline in vehicle coordinates based on the detected lines; determining corrected vehicle coordinates based on the centerline in vehicle coordinates and the vehicle coordinates from the ground truth data; and generating control signals to navigate the vehicle along the route using the corrected vehicle coordinates. The visual positioning system may maintain localization accuracy and provide drift correction in the presence of poor GPS or radio localization.
