Method for determining position of a trailer and device for determining position of a trailer

A device for determining position of a trailer, the device comprising:

• a processor;
• a camera mountable on a second vehicle coupled to a first vehicle, wherein one of the first vehicle and the second vehicle is a trailer, and wherein the other vehicle of the first vehicle and the second vehicle is a towing vehicle configured to tow the trailer,
• wherein in use, the camera is configured to, after the first vehicle is positioned at a known position relative to a second vehicle, generate a reference image of the first vehicle using the camera, wherein the reference image captures a feature of the first vehicle, and wherein the processor is configured to determine a pixel position of the feature in the reference image;
• wherein subsequently, the camera is configured to generate an input image of the first vehicle, the input image capturing the feature of the first vehicle, and
• wherein the processor configured to determine a pixel position of the feature in the input image, and wherein the processor is further configured to determine the position of the first vehicle relative to the second vehicle based upon comparing the pixel position of the feature in the reference image to the pixel position of the feature in the input image.

A vehicle for coupling to a further vehicle, the vehicle comprising:

• a camera configured to generate a reference image and subsequently an input image of a further vehicle when the further vehicle is coupled to the vehicle;
• and
• a processor configured to determine a pixel position of a feature in the reference image and subsequently determine a pixel position of the feature in the input image, and wherein the processor is further configured to determine the position of the vehicle relative to the further vehicle further based on comparing the pixel position of the feature in the reference image to the pixel position of the feature in the input image,
• wherein the vehicle is one of a trailer towable by the further vehicle, and a towing vehicle configured to tow the further vehicle.
