Patent attributes
A method and apparatus for trailer recognition are provided. The method includes detecting a face of a trailer in a first and second image, taken at first and second distances respectively, generating a bounding box around the face of the trailer in the first and second images, determining a first and second set of feature points in the bounding boxes of the first and second images, determining a correspondence between the first set of feature points and the second set of feature points and a correspondence between corners of the bounding boxes and estimating at least one dimension of the trailer by performing a least squares analysis to solve for three-dimensional real world coordinates of the first and second set of features points and the corners of the bounding boxes. The method may assist an operator of a vehicle in aligning the vehicle hitch with a trailer coupler.
