Mashup of ap location and map information for wifi based indoor positioning

A mobile device for merging disjointed maps, the device comprising:

• means for receiving a digital file comprising a route map;
• means for receiving a transmitter map comprising identifiers for a plurality of transmitters;
• means for receiving a first trajectory plot, of a mobile device, relative to the transmitter map;
• means for setting a plurality of hypotheses each defining a unique translation between the transmitter map and the route map;
• means for computing a plurality of costs, wherein each cost of the plurality of costs comprises a cost of the first trajectory plot through the route map based on a respective one of the plurality of hypotheses;
• and
• means for selecting one hypothesis from the plurality of hypotheses, based on a minimum of the plurality of costs.

A device comprising a processor and a memory for merging disjointed maps, wherein the memory includes software instructions for:

• receiving a digital file comprising a route map;
• receiving transmitter map comprising identifiers for a plurality of transmitters;
• receiving a first trajectory plot, of a mobile device, relative to the transmitter map;
• setting a plurality of hypotheses each defining a unique translation between the transmitter map and the route map;
• computing a plurality of costs, wherein each cost of the plurality of costs comprises a cost of the first trajectory plot through the route map based on a respective one of the plurality of hypotheses;
• and
• selecting one hypothesis from the plurality of hypotheses, based on a minimum of the plurality of costs.

A computer-readable storage medium including program code stored thereon, comprising program code for:

• receiving a digital file comprising a route map;
• receiving a transmitter map comprising identifiers for a plurality of transmitters;
• receiving a first trajectory plot, of a mobile device, relative to the transmitter map;
• setting a plurality of hypotheses each defining a unique translation between the transmitter map and the route map;
• computing, in a processor, a plurality of costs, wherein each cost of the plurality of costs comprises a cost of the first trajectory plot through the route map based on a respective one of the plurality of hypotheses;
• and
• selecting one hypothesis from the plurality of hypotheses, based on a minimum of the plurality of costs.
