Abstract
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 having a trailer contour and matches the template image to a search image. The hitch angle is determined based on a positional relationship between the template image and the search image.
