Accurate Positioning System Using Attributes

摘要

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.

1. A mobile device coupled to a position identification system comprising:
an operating system coupled to a camera; a scanning and image recognition unit coupled to the operating system; an attribute database coupled to the scanning and image recognition unit; an attribute-position database coupled to the scanning and image recognition unit; each of a plurality of descriptions in the attribute database describing a corresponding attribute; and each entry in the attribute-position database associating an attribute with a corresponding position, wherein an image obtained by the camera containing a first attribute is coupled to the scanning and image recognition unit which matches the description of the first attribute to one of the plurality of descriptions in the attribute database, wherein the matched description of one of the plurality of descriptions is entered to the attribute-position database to find a position of the first attribute.
