Abstract
The disclosure relates to an apparatus for determining an angle of a trailer with respect to a vehicle. A camera captures first, second, and third images when the trailer is at a first, second, third orientations respectively with respect to the vehicle. A processing unit determines at least one image location of at least one feature of the trailer in the first image, the second image, and the third image. The processing unit determines a rotational angle of the trailer about the tow ball for the trailer in the third orientation with respect to the first orientation comprising utilization of the at least one 3D location of the at least one feature of the trailer when the trailer was in the first orientation and the 3D location of the one feature of the trailer when the trailer was in the third orientation.
