A system for locating a coupler of a trailer includes at least one camera positioned on a rear portion of a tow vehicle. A coupler detector module is constructed and arranged 1) to receive images of the coupler from the at least one camera and 2) to determining a two-dimensional (2D) pixel position of the coupler. A camera motion estimator module is constructed and arranged 1) to receive images from the at least one camera and data regarding motion of the tow vehicle and 2) determine a pose of the camera including a three-dimensional (3D) position and heading of the at least one camera. A coupler estimator module is constructed and arranged 1) to receive the pose of the camera and the 2D pixel position of the coupler and based thereon, 2) to determine an estimated 3D position of the coupler in real world coordinates.
