Abstract
A method for autonomously maneuvering a tow vehicle. The method includes receiving images from one or more cameras positioned on a back portion of the tow vehicle and receiving sensor data from an inertial measurement unit supported by the tow vehicle. The method also includes determining a pixel-wise intensity difference between a current received image and a previous received image. The method includes determining a camera pose and a trailer pose with respect to a world coordinate system. The camera pose and the trailer pose are based on the images, the sensor data, and the pixel-wise intensity difference. The method includes determining a tow vehicle path based on the camera pose and the trailer pose. The method also includes instructing a drive system supported by the tow vehicle to autonomously maneuver along the tow vehicle path in a reverse direction causing the tow vehicle to hitch with the trailer.
