Abstract
Techniques are described for tracking a trailer, including obtaining a sequence of images from a camera positioned in rear of a vehicle, detecting the trailer and a tow-ball in the first image of the sequence of images using a trained learning model based on the first image and at least one scaled version of the first image, estimating an area of interest using a tracking algorithm and locations of the detected trailer and the tow-ball in the first image, estimating a distance between the vehicle and the trailer based on the detected location of the trailer in the first image, and upon determining that the distance between the vehicle and the trailer is less than a second threshold, continuously detecting locations of the trailer, tow-ball and a coupler in each image of the sequence of images using the learning model and the estimated area of interest, and updating the estimated area of interest to correspond to an area of interest in the following image, and actuating an action of the vehicle based on the detected locations of the trailer, tow-ball and the coupler.
