Template matching solution for locating trailer hitch point

摘要

A system for detecting a hitch angle between a vehicle and a trailer is provided herein. An imaging device is configured to capture images of the trailer and a controller is configured to process images captured by the imaging device. The controller derives a template image and rotates the template image relative to a search image about an imaged hitch point that is common to the template image and the search image. The location of the imaged hitch point corresponds to a selected one of a number of candidate hitch point locations. The hitch angle is determined based on an angle at which the template image is rotated relative to the search image to generate a match therebetween.
