Abstract
A method for determining a location of a target positioned behind a tow vehicle is provided. The method includes receiving images from a camera positioned on a back portion of the tow vehicle. The images include the target. The method includes applying one or more filter banks to the images. The method also includes determining a region of interest within each image based on the applied filter banks. The region of interest includes the target. The method also includes identifying the target within the region of interest and determining a target location of the target including a location in a real-world coordinate system. The method also includes transmitting instructions to a drive system supported by the vehicle. The instructions cause the tow vehicle to autonomously maneuver towards the location in the real-world coordinate system.
