Abstract
A system and methods related to hitch assist are provided herein. An imager captures rear-vehicle images. A processor is configured to extract trailer and ground features from the captured images, compute vehicle motion displacement based on optical flow of the ground features, estimate a height of each trailer feature based on vehicle motion displacement and optical flow of the trailer features, and determine a trailer height based on the estimated heights of at least a portion of the trailer features.
