Abstract

Mobile terminals, methods and computer program products are provided for scanning and calibrating a map using a mobile terminal. A map is scanned into the mobile terminal using the mobile terminal as a scanner. Multiple reference coordinates associated with locations on the scanned map are received at the mobile terminal from a global positioning system (GPS) associated with the mobile terminal. The scanned map is calibrated in the mobile terminal based on the received multiple reference coordinates.

Claims

1. A mobile terminal, comprising:

a scanner module configured to scan a map into the mobile terminal; and

a calibration module, coupled to the scanner module, configured to receive multiple reference coordinates associated with locations on the scanned map from a global positioning system (GPS) associated with the mobile terminal and calibrate the scanned map in the mobile terminal based on the received multiple reference coordinates.

2. The mobile terminal of claim 1, wherein the calibration module is further configured to:

acquire additional reference coordinates associated with locations on the scanned map; and

recalibrate the scanned map upon acquisition of the additional reference coordinates.

3. The mobile terminal of claim 1, wherein the calibration module is configured to receive the multiple reference coordinates and calibrate the scanned map within the mobile terminal without communicating with an external communications device.

4. The mobile terminal of claim 1, wherein the multiple reference coordinates are associated with a current position of the user so as to allow calibration of the scanned map based on the current position.

5. The mobile terminal of claim 1, further comprising a camera module, wherein the scanner module is associated with the camera module and wherein the scanner module is configured to scan the map by taking a picture of the map.

6. The mobile terminal of claim 1, wherein the scanner module is further configured to:

scan the map in multiple segments; and

concatenate the multiple segments of the map into a single cohesive map.

7. The mobile terminal of claim 1, further comprising a GPS module integrated in the mobile terminal.

8. A method of scanning and calibrating a map using a mobile terminal, comprising:

scanning a map into the mobile terminal using the mobile terminal as a scanner;

receiving, at the mobile terminal, multiple reference coordinates associated with locations on the scanned map from a global positioning system (GPS) associated with the mobile terminal; and

calibrating the scanned map in the mobile terminal based on the received multiple reference coordinates.

9. The method of claim 8, further comprising:

determining if additional reference coordinates associated with locations on the scanned map have been acquired; and

recalibrating the scanned map in the mobile terminal if it is determined that additional reference coordinates have been acquired.

10. The method of claim 8, wherein receiving and calibrating further comprise receiving and calibrating without communicating with an external communications device.

11. The method of claim 8, wherein the multiple reference coordinates are associated with a current position of the user so as to allow calibration of the scanned map based on the current position.

12. The method of claim 8, wherein scanning a map comprises taking a picture of the map.

13. The method of claim 8, wherein scanning further comprises:

scanning the map in multiple segments; and

concatenating the multiple segments of the map into a single cohesive map.

14. The method of claim 8, wherein the GPS associated with the mobile terminal is integrated in the mobile terminal.

15. A computer program product for scanning and calibrating a map using a mobile terminal, the computer program product comprising:

a computer readable medium having computer readable program code embodied therein, the computer readable program code comprising;

computer readable program code configured to scan a map into a mobile terminal using the mobile terminal as a scanner;

computer readable program code configured to receive, at the mobile terminal, multiple reference coordinates associated with locations on the scanned map from a global positioning system (GPS) associated with the mobile terminal; and

computer readable program code configured to calibrate the scanned map in the mobile terminal based on the received multiple reference coordinates.

16. The computer program product of claim 15, further comprising:

computer readable program code configured determine if additional reference coordinates associated with locations on the scanned map have been acquired; and

computer readable program code configured to recalibrate the scanned map in the mobile terminal if it is determined that additional reference coordinates have been acquired.

17. The computer program product of claim 15, wherein the computer readable program code configured to receive and the computer readable program code configured to calibrate further comprise computer readable program configured to receive and calibrate without communicating with an external communications device.

18. The computer program product of claim 15, wherein the multiple reference coordinates are associated with a current position of the user so as to allow calibration of the scanned map based on the current position.

19. The computer program product of claim 15, wherein the computer readable program code configured to scan comprises computer readable program code configured to take a picture of the map.

20. The computer program product of claim 15, wherein the computer readable program code configured to scan further comprises:

computer readable program code configured to scan the map in multiple segments; and

computer readable program code configured to concatenate the multiple segments of the map into a single cohesive map.
