Abstract
A system includes a processor configured to receive a trailer image. The processor is also configured to identify an axle in the trailer image and identify a tongue-end in the trailer image. Further, the processor is configured to receive a tire image, including a wheel diameter provided on a tire. The processor is additionally configured to retrieve the wheel diameter from the tire image. The processor is also configured to identify a wheel, having an indentified diameter corresponding to the wheel diameter, in the first image. Additionally, the processor is configured to calculate a distance from the axle to the tongue-end using the identified diameter.
