Abstract
A system for determining at least one pitch angle of a trailer relative to a towing vehicle, the system including a camera mounted on the towing vehicle and capable of acquiring images of the trailer in which lines of the trailer parallel to the axis of the trailer are visible, and a computer configured to perform the following steps: implementing a line-detection algorithm on at least one image of the trailer acquired by the camera, detecting in the image the lines of the trailer parallel to the trailer axis, corresponding to vanishing lines, and deducing from the vanishing lines a position of the vanishing point, and from the coordinates of the vanishing point, determining at least one pitch angle of the trailer with respect to the towing vehicle.
