Abstract
An optical recognition based positioning method and a positioning system, which can replace or compensate conventional satellite-based GPS, is provided. A position is determined utilizing a digital image, which captured a set of optical marks of known geographic coordinates. The distances in pixel coordinates of the optical marks within the digital image are converted into an angle at the camera between the actual geographical coordinate of the optical marks. A first group of points having the same angle as the first and second optical marks are identified. A second group of points having the same angle as the second and third optical marks are identified. Also, a third group of points having the same angle as the first and third optical marks are identified. Then, a point that co-exist in the first, second and the third group is identified as the geographical location of the positioning module.
