Abstract
A system is for mapping an interior of a building. The system may include a mobile device having a PDR circuit configured to generate PDR positions as a user moves within the interior of the building, and a ranging circuit configured to generate ranging mapping data of the interior of the building as the user moves within the interior of the building. The system also may include a server configured to map the interior of the building and generate a location of the mobile device within the interior of the building based upon the PDR positions and the ranging mapping data from the mobile device.
Claims23
A system for mapping an interior of a building, the system comprising:
- at least one mobile device comprising
- a pedestrian dead reckoning (PDR) circuit configured to generate a plurality of PDR positions as a user moves within the interior of the building, and
- a ranging circuit configured to generate ranging mapping data of the interior of the building as the user moves within the interior of the building and convert the ranging mapping data to graphics data;
- and
- a server configured to map the interior of the building and generate a location of said at least one mobile device within the interior of the building based upon the plurality of PDR positions and the graphics data from said at least one mobile device.
A method for operating a system for mapping an interior of a building, the method comprising:
- operating a pedestrian dead reckoning (PDR) circuit in at least one mobile device to generate a plurality of PDR positions as a user moves within the interior of the building;
- operating a ranging circuit in the at least one mobile device to generate ranging mapping data of the interior of the building as the user moves within the interior of the building and convert the ranging mapping data to graphics data;
- and
- operating a server in communication with the at least one mobile device to map the interior of the building and generate a location of the at least one mobile device within the interior of the building based upon the plurality of PDR positions and the graphics data from the at least one mobile device.
A server for mapping an interior of a building in cooperation with at least one mobile device comprising a pedestrian dead reckoning (PDR) circuit configured to generate a plurality of PDR positions as a user moves within the interior of the building, and a ranging circuit configured to generate ranging mapping data of the interior of the building as the user moves within the interior of the building and convert the ranging mapping data to graphics data, the server comprising:
- a processor and an associated memory configured to
- obtain the plurality of PDR positions and the graphics data from the at least one mobile device, and
- map the interior of the building and generate a location of the at least one mobile device within the interior of the building based upon the plurality of PDR positions and the graphics data from the at least one mobile device.
