Abstract: 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 a y position in the at least the first image to an x position in the at least the first image. A trailer angle is determined. A current wheel location is estimated by applying the determined trailer angle to the parabola curve.

The method also includes determining an optical flow within the region of interest, and determining that a trailer is connected to the vehicle in response to the optical flow within the region of interest matching a predetermined pattern corresponding to a connected trailer. A camera monitoring system for a vehicle is also disclosed.
