Accurate positioning system using attributes
A Position Identification Solution offers a way to determine the position of a Mobile Device by defining a set of known positions and an associated set of objects, shapes, or attributes. A Mobile Device determines its position by scanning an object, shape, or attribute using an included camera, and a Mobile Application running on the Mobile Device recognizes a specific object, shape, or attribute, and determines a corresponding position, which is used to compute the position of the Mobile Device. The Position Identification Solution may use shapes, colors, or combinations of shape and colors. The Position Identification Solution may be used together with other positioning systems in a Hybrid Positioning System to compute the position of the Mobile Device with increased accuracy.
