Abstract
A method for detecting a trailer presence includes identifying a region of interest within a video feed from one or more cameras secured to a vehicle. The video feed depicts a scene having a first pixel area, and the region of interest corresponds to a portion of the scene having a second pixel area that is less than the first pixel area. 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.
