Zusammenfassung:A method of detecting and localizing a coupler of a trailer hitch associated with a trailer positioned behind a tow vehicle is provided. The method includes determining a region of interest within images from a rear camera. The region of interest includes a representation of the trailer hitch. The method includes determining a three-dimensional (3D) point cloud representing objects inside the region of interest. The method includes determining a camera plane based on the images. The method includes projecting the cloud points onto the camera plane and determining a coupler location based on the projected cloud points onto the camera plane. The method includes determining a path based on the coupler location. The path ending when the tow vehicle is attached to the trailer. The method also includes sending instructions to a drive system causing the tow vehicle to autonomously drive in a rearward direction along the path.
