Abstract: Disclosed are a system for identifying the position of mobile object, comprising a positioning module, a set of beacons and processor configured to determine the position of the positioning module based on the data gathered from the interaction between the positioning module and each one of the set of beacons. More specifically, the limited area positioning system utilizes signal emitted from the positioning module and the signals emitted from the each of the beacons in response to the signal from the positioning module. Using the signals transmitted from the positioning module and the beacons, at least three circles can be formed, and the limited area positioning system determines the intersecting point of those three circles as the position of the positioning module.

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.
