Camera monitor system for commercial vehicles including wheel position estimation

WEI Wenpeng, L Ma, Y Men, TO Cooprider - US Patent 12,115,917, 2024 - Google Patents
A method for estimating a trailer wheel position includes identifying a first set of wheel
locations in a first image. Each of the wheel locations in the first set of wheel locations is
associated with a corresponding trailer angle. The first set of wheel locations is clustered
and a primary cluster in the first set of wheel locations is identified. A best fit curve is applied
to the primary cluster. The best fit curve is a curve associating wheel position to trailer angle.
An estimated wheel position is determined by applying a determined trailer angle to the best …

A method for estimating a trailer wheel position includes identifying a first set of wheel
locations in at least a first image. Each of the wheel locations in the first set of wheel
locations is associated with a corresponding trailer angle. A subset of wheel locations is
identified in the first set of wheel locations as being false positives and the false positives are
removed from the first set of wheel locations. A quadratic regression is applied to the first set
of wheel locations and a parabola curve is determined relating ay position in the at least the …
