1. A method for ascertaining an orientation of a trailer relative to a tractor vehicle, wherein the tractor vehicle comprises at least one detection device which detects a first object region on the trailer and a second object region on the trailer, comprising:
recording the first object region and the second object region by at least one detection device;
providing the recording detected by the at least one detection device to an evaluation device;
assigning a first information item to the first object region and a second information item to the second object region by the evaluation device; and
determining the orientation of the trailer relative to the tractor vehicle on the basis of the first information item and the second information item by the evaluation device;
wherein the evaluation device is configured for component recognition in the first object region and/or second object region;
wherein the component located inside the first object region and/or second object region comprises a supporting jack and/or a supporting jack base and/or a reinforcing cross and/or a connecting shaft; and
wherein the evaluation device carries out an object recognition, wherein the object recognition assigns the first object area and/or the second object area to the component via recorded contours, and wherein the first and/or second information represents relative position of the first object area relative to the second object area, and represents a size of the components and/or an orientation of the components in the first and/or second object area.
