Abstract: A system and method for locating a trailer coupler on a trailer to assist with the coupling of the trailer coupler to a vehicle hitch on a vehicle. The system includes a human-machine interface, a camera, a global positioning system, a remote computing system, a vehicle-to-infrastructure communication network, controllers, a memory, sensors, and a trailer coupler labeling application. The trailer coupler labeling application includes: sensing at least one of a hitched state and an unhitched state of the trailer coupler, capturing an optical data with the camera when the vehicle hitch is in the hitched and unhitched state, determining a distance of the trailer coupler relative to the camera when the vehicle hitch is in the hitched state, identifying the location of the trailer coupler on an image defined by the captured data and creating a label on the image of the trailer coupler.

Abstract: A method of detecting and utilizing a 3-dimensional (3D) position of a coupler of a trailer may include calculating a motion of a camera mounted to a vehicle; determining 2-dimensional (2D) positions of the coupler within input images captured by the camera; estimating 3D estimated positions of the coupler based on the 2D positions of the coupler and the motion of the camera; optimizing the 3D estimated positions of the coupler to generate adjusted 3D coupler positions; and filtering the adjusted 3D coupler positions to detect the 3D position of the coupler of the trailer.
