COMMERCIAL VEHICLE CAMERA MONITOR SYSTEM WITH TRAILER WHEEL BASE ESTIMATION

A method for determining wheel base for a trailer attached to a tractor includes a) identifying a two-dimensional trailer wheel location in an image, b) associating the two-dimensional trailer wheel location with a corresponding trailer angle, c) converting the two-dimensional trailer wheel location to a three-dimensional trailer wheel location, d) calculating a wheel base from the three-dimensional trailer wheel location, e) acquiring a new two-dimensional trailer wheel location, f) performing steps b)-d) for the new two-dimensional trailer wheel location, and g) calculating an average wheel base based upon a previous average wheel base and the new two-dimensional trailer wheel location.
