This abstract first appeared for US patent application 20250128553 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.
