Abstract

Methods and systems for map generation for location and navigation with user sharing/social networking may comprise in connection with a crowd-sourced database that receives images and location data from a plurality of users of wireless communication devices (WCDs), and for at least one of said plurality of users: receiving a determined position of a WCD, wherein the position is determined based at least in part on: capture of one or more images of the surroundings of the WCD; and extraction of data associated with objects in the captured one or more images. The crowd-sourced database may be updated based on the determined position of the WCD and said extracted data. Data associated with objects in the surroundings of the WCD may be extracted from the captured images, positions of the objects may be determined, and the determined positions and the data may then update the premises-based crowd-sourced database.

Claims

1. A method for communication, the method comprising:

in connection with a core premises map and a crowd-sourced database that receives images and location data from a plurality of users of wireless communication devices, and for at least one of said plurality of users;

receiving a determined position of a wireless communication device, wherein the determined position is determined based at least in part on;

capture of one or more images of the surroundings of said wireless communication device; and

extraction of data from the captured one or more images, said data associated with objects in the captured one or more images and/or said core premises map; and

updating said crowd-sourced database based on said determined position of said wireless device and said extracted data.

2. The method according to claim 1, comprising determining said position of said wireless communication device utilizing camera imaging and structural and/or textual features compared to features in said crowd-sourced database.

3. The method according to claim 1, wherein said data associated with objects in the captured one or more images comprise structural features in a vicinity of said wireless communication device.

4. The method according to claim 1, wherein said data associated with objects in the captured one or more images comprise textual features in a vicinity of said wireless communication device.

5. The method according to claim 1, comprising determining said position of said wireless communication device utilizing one or more sensors in said wireless communication device to measure a distance from a last determined or known position.

6. The method according to claim 5, wherein said one or more sensors comprise one or more of:

a pedometer, an altimeter, a camera, multidimensional accelerometers, gyroscopes, and a multi-dimensional compass.

7. The method according to claim 1, comprising determining positions of said objects in the captured one or more images utilizing known optical characteristics of a camera in said wireless communication device.

8. The method according to claim 1, wherein said database comprises one or more of:

a plurality of images, abstractions of images, and locations.

9. The method according to claim 1, wherein said crowd-sourced database is stored on a server on a premises corresponding to the crowd-sourced database.

10. The method according to claim 1, wherein said wireless communication device comprises a device used by an owner and/or a proprietor of a premises corresponding to said crowd-sourced database.

11. The method according to claim 1, wherein said determined position is also determined based on a determination of positions of said objects in the captured one or more images, and wherein said updating said crowd-sourced database is also based on said determined positions of said objects.

12. A system for communication, the system comprising:

one or more circuits for use in connection with a core premises map and a crowd-sourced database that receives images and location data from a plurality of users of wireless communication devices, said one or more circuits being operable to, for at least one of said plurality of users;

receive a determined position of a wireless communication device, wherein the position is determined based at least in part on;

capture of one or more images of the surroundings of said wireless communication device; and

extraction of data from the captured one or more images, said data associated with objects in the captured one or more images and/or said core premises map; and

update said crowd-sourced database based on said determined position of said wireless device and said extracted data.

13. The system according to claim 12, wherein said one or more circuits are operable to determine said position of said wireless communication device utilizing camera imaging and structural and/or textual features compared to features in said crowd-sourced database.

14. The system according to claim 12, wherein said data associated with objects in the captured one or more images comprise structural features in a vicinity of said wireless communication device.

15. The system according to claim 12, wherein said data associated with objects in the captured one or more images comprise textual features in a vicinity of said wireless communication device.

16. The system according to claim 12, wherein said one or more circuits are operable to determine said position of said wireless communication device utilizing one or more sensors in said wireless communication device to measure a distance from a last determined or known position.

17. The system according to claim 16, wherein said one or more sensors comprise one or more of:

a pedometer, an altimeter, a camera, multidimensional accelerometers, gyroscopes, and a multi-dimensional compass.

18. The system according to claim 12, wherein positions of said objects in the captured one or more images are determined utilizing known optical characteristics of a camera in said wireless communication device.

19. The system according to claim 12, wherein said crowd-sourced database comprises one or more of:

a plurality of images, abstractions of images, and locations.

20. The system according to claim 12, wherein said crowd-sourced database is stored on a server on a premises corresponding to the crowd-sourced database.

21. The system according to claim 12, wherein said wireless communication device comprises a device used by an owner and/or a proprietor of a premises corresponding to said crowd-sourced database.

22. The system according to claim 12, wherein said determined position is also determined based on a determination of positions of said objects in the captured one or more images, and wherein said updating said crowd-sourced database is also based on said determined positions of said objects.

23. A system for communication, the system comprising:

one or more circuits for use in connection with a core premises map and a crowd-sourced database that receives images and location data from a plurality of users of wireless communication devices, said one or more circuits being operable to, for at least one of said plurality of users;

receive a determined position of a wireless communication device based on a distance traveled from a last determined or known position, wherein the determined position is determined based at least in part on;

capture of one or more images of the surroundings of said wireless communication device; and

extraction of data from the captured one or more images, said data associated with objects in the captured one or more images and/or said core premises map; and

update said crowd-sourced database based on said determined position of said wireless device and said extracted data.
