Abstract

The present invention provides a method, a computer program, and device for navigation assistance where the method and the computer program may include receiving location information related to the geographical location of a device for navigation assistance, continuously receiving visual information registered by a camera, displaying the visual information received, calculating the geographical coordinates of the device from the received location information related to the geographical location of the device and analyzing the visual information received and relating it to the calculated geographical location of the device.

Claims

1. A device for navigation assistance comprising at least one receiver for receiving location information related to the geographical location of the device, the device being arranged to continuously receive visual information registered by a camera, and a display for displaying the visual information received, the device further comprising a memory for storing location information related to the region or area through which the device is moving and a processing unit for continuously calculating the geographical coordinates of the device from the location information related to the geographical location of the device, wherein the processing unit is arranged to continuously analyze the visual information received from the camera and to relate it to the information indicative of the geographical location of the device.

2. The device of claim 1, wherein the device for navigation is built-in into a motor vehicle.

3. The device of claim 1, wherein the device for navigation comprises a mobile phone.

4. The device of claim 1, wherein the device additionally comprises a transmitter for communication with access points or base stations in a wireless communication network.

5. The device of claim 1, wherein the visual information registered by a camera comprises scenery in the direction of movement of the device.

6. The device of claim 1, wherein the camera is integrated with the device.

7. The device of claim 1, wherein the viewfinder is additionally arranged to display information comprising speed, geographical coordinates, distance to destination and geographical map of the area surrounding the geographical coordinates of the device.

8. The device of claim 1, wherein the device further comprises a user interface for permitting a user of the device to specify a geographical destination he intends to reach in the device.

9. The device of claim 1, wherein the processing unit is further arranged to distinguish primary objects, such as paths, streets, roads or freeways from other secondary objects, such as buildings, trees and the like in the visual information registered by a camera to extract these primary objects from the visual information.

10. The device of claim 1, wherein the memory is arranged to store geographical maps of the area or region of the geographical coordinates for the device.

11. The device of claim 9, wherein the processing unit is arranged to, using the calculated geographical coordinates for the device, map the extracted primary objects to a corresponding object of the geographical map.

12. The device of claim 1, wherein the processing unit is arranged to, based on the calculated geographical coordinates for the device and the geographical coordinates for the destination, calculate the next movement direction for the user and to indicate that direction by a direction indicator on the display of the device.

13. The device of claim 1, wherein the navigation is performed in a global satellite navigation system, such as satellite (Global Positioning System), Galileo or GLONASS (Global Navigation Satellite System).

14. The device of claim 1, wherein the navigation is performed in a wireless communication network, such as a GSM (Global System for Mobile telephony), UMTS (Universal Mobile Telephony System), IEEE 802.11 series (a, b, g, n) or some other wireless communication network capable of locating a mobile terminal.

15. A device for navigation assistance comprising at least one receiver for receiving location information related to the geographical location of the device, the device being arranged to intermittently receive visual information registered by a camera, and a display for displaying the visual information received, the device further comprising a memory for storing location information related to the region or area through which the device is moving and a processing unit for intermittently calculating the geographical coordinates of the device from the location information related to the geographical location of the device, wherein the processing unit is arranged to intermittently analyze the visual information received from the camera and to relate it to the information indicative of the geographical location of the device.

16. A system for navigation assistance comprising at least one receiver for receiving location information related to the geographical location of the receiver, a camera for registering visual information in the direction in front of the camera, a display in communication with the camera for displaying the visual information registered by the camera, the system further comprising a memory for storing location information related to the region or area through which the receiver is moving and a processing unit in communication with the memory for continuously calculating the geographical coordinates of the receiver from the location information related to the geographical location of the receiver,

wherein the processing unit is further in communication with the camera and arranged to continuously analyze the visual information received from the camera and to relate it to the information indicative of the geographical location of the receiver.

17. A method comprising:

a) receiving location information related to the geographical location of a device for navigation assistance;

b) continuously receiving visual information registered by a camera;

c) displaying the visual information received

d) calculating the geographical coordinates of the device from the received location information related to the geographical location of the device, wherein the method further comprises;

e) continuously analyzing the visual information received and relating it to the calculated geographical location of the device.

18. A computer program for navigation assistance comprising instruction sets for:

a) continuously receiving location information related to the geographical location of a device for navigation assistance;

b) receiving visual information registered by a camera;

c) displaying the visual information received

d) calculating the geographical coordinates of the device from the received location information related to the geographical location of the device, wherein the method further comprises;

e) continuously analyzing the visual information received and relating it to the calculated geographical location of the device.
