Accurate positioning system using attributes

A mobile device coupled to a position identification system, the mobile device comprising:

• a processor;
• and
• a memory storing one or more programs for execution by the processor, the one or more programs including instructions for:
• capturing an image using an image capture device;
• storing a plurality of descriptions, a plurality of attributes, and a plurality of positions in a database, each description in the database describing a respective attribute, and each attribute being associated with a respective position;
• supplying the image, captured by the image capture device, to an image recognition device;
• and
• matching a description of a first attribute of the image received by the image recognition device to one of the plurality of descriptions in the database, wherein a matched description is used to determine a position of the first attribute and a location of the image capture device such that the position of the first attribute is used as the location of the image capture device.

A non-transitory computer readable storage medium storing one or more programs configured to be executed by a processor, the one or more programs comprising instructions for:

• capturing an image using an image capture device;
• storing a plurality of descriptions, a plurality of attributes, and a plurality of positions in a database, each description in the database describing a respective attribute, and each attribute being associated with a respective position;
• supplying the image, captured by the image capture device, to an image recognition device;
• and
• matching a description of a first attribute of the image received by the image recognition device to one of the plurality of descriptions in the database, wherein a matched description is used to determine a position of the first attribute and a location of the image capture device such that the position of the first attribute is used as the location of the image capture device.
