A method for determining features of a trailer being towed by a vehicle includes initiating a calibration drive of the vehicle and capturing frames of image data via a vehicle camera, and, via processing by an image processor of frames of captured image data, determining features of the trailer being towed by the vehicle during the calibration drive. The features of the trailer are determined by determining features that have similar changes between a current frame of captured image data and a previous frame of captured image data captured during the calibration drive. The features are tracked over multiple frames of captured image data for different angular positions of the trailer relative to the vehicle to determine trailer length from the hitch ball of the vehicle to an axle of the trailer. The trailer angle is determined based on the determined trailer length.
