Abstract

The method comprises performing said calculation by using data provided by an image recognition process which identifies at least one geo-referenced image of an object located in the surroundings of said personal device. The system is arranged for implementing the method of the present invention.

Claims

1-19. -19. (canceled)

20. A method for calculating the geo-location of a personal device that comprises:

performing said calculation by using data provided by an image recognition process which identifies at least one geo-referenced image of an object located in the surroundings of said personal device;

taking said image of an object located in the surroundings of said personal device with said personal device and matching said image with a dataset of indexed geo-referenced images;

wherein said calculation further comprises using the results of said image recognition fused with information provided by a GPS antenna available in said personal device; and

using the information of an accelerometer or a digital compass available in said personal device in order to perform said calculation, characterized in that the coordinates of said geo-location of said personal device are calculated according to the following formula;

21. A method as per claim 20, comprising employing said calculation to display geo-tagged Points of Interest (POI) on a graphical user interface of said personal device.

22. A method as per claim 20, comprising constraining said image recognition process to those geo-referenced images placed in a certain radius from said image of an object located in the surroundings of said personal device.

23. A system for calculating the geo-location of a personal device, the system performing said calculation by using data provided by a visual recognition module which identifies at least one geo-referenced image of an object located in the surroundings of said personal device.

24. A system as per claim 23, comprising implementing said system in a client-server framework where said calculation is performed on the server side.

25. A system as per claim 24, comprising using a service layer module which at least:

provides information of the geo-location to said personal device; and

forwards the information received from said personal device to said visual recognition module.

26. A system as per claim 24, wherein said visual recognition module employs GPS information provided by said personal device to restrain said identification to those images located in the surroundings of said object.

27. A system as per claim 25, wherein said service layer provides said personal device with a list of POIs.

28. A system as per claim 25, wherein said service layer provides said personal device with a map of POIs.

29. A system as per claim 27, wherein said list and/or map of POIs is displayed on a graphical user interface of said personal device.

30. A system as per claim 25, wherein said service layer provides said personal device with a view of Points of Interest (POIs) that are displayed superimposed to the image provided by a camera of said personal device on a graphical user interface of said personal device.

31. A system as per claim 27, wherein said list, map or view of Points of Interest (POIs) provided by said service layer to said personal device contains geo-tagged information of said POIs.

32. A system as per claim 24, comprising using a fusion of data module which provides an estimation of the geo-location of said personal device using at least the result of said visual recognition module.

33. A system as per claim 32, wherein said fusion of data module combines the result of said visual recognition module with GPS information provided by said personal device.

34. A system as per claim 33, wherein said fusion of data module further uses data provided by compass or accelerometers of said personal device when performing said combination.
