This abstract first appeared for US patent application 18491262 titled 'METHOD TO DETECT A TRAILER COUPLER POSITION USING CAMERA-BASED TRIANGULATION, OPTIMIZATION AND FILTERING
Original Abstract Submitted
A method of detecting and utilizing a 3-dimensional (3D) position of a coupler of a trailer may include calculating a motion of a camera mounted to a vehicle; determining 2-dimensional (2D) positions of the coupler within input images captured by the camera; estimating 3D estimated positions of the coupler based on the 2D positions of the coupler and the motion of the camera; optimizing the 3D estimated positions of the coupler to generate adjusted 3D coupler positions; and filtering the adjusted 3D coupler positions to detect the 3D position of the coupler of the trailer.
