1. A vehicular trailer hitching assist system, the vehicular trailer hitching assist system comprising:
a camera disposed at a rear portion of a vehicle equipped with the vehicular trailer hitching assist system, the camera viewing at least rearward of the vehicle, wherein the camera is operable to capture image data;
wherein, during a reversing maneuver of the vehicle toward a trailer that is spaced from the vehicle at a distance from the vehicle, the camera views at least a portion of a front profile of the trailer;
an electronic control unit (ECU) comprising electronic circuitry and associated software;
wherein the electronic circuitry comprises an image processor operable to process image data captured by the camera;
wherein the vehicular trailer hitching assist system, via image processing at the ECU of image data captured by the camera during the reversing maneuver of the vehicle toward the trailer, determines a plurality of landmarks corresponding to the front profile of the trailer; and
wherein, based at least in part on the determined plurality of landmarks, the vehicular trailer hitching assist system determines location of a trailer coupler of the trailer.
