Abstract
A method for calculating a tow hitch position of a trailer is presented. A first and a second image of the trailer is captured and a trailer rotation and translation relative to a known zero pose of the trailer based on the captured first and second images is calculated. The rotation axes of the trailer in the first and second image is calculated based on the calculated trailer rotations and translations. An intersection of the first and second rotation axis is calculated to determine a ray to the tow hitch position. The ray to the tow hitch position and a geometrical condition are used to calculate the tow hitch position.
