Abstract
A relative positioning system, an arrangement, and a method. A method for determining a position of a second vehicle relative to a first vehicle. At least an image of a field of view wherein the second vehicle is positioned within the field of view is recorded using an optical device mounted on the first. Image data is processed in a processor to determine a position of the second vehicle relative the first vehicle measuring at least one marker arranged on the second vehicle in the image.
