Abstract

A digitized image of a map is stored in a data memory. At least one point of the image of the map is selected as reference point. Space coordinates of the location which corresponds to the reference point are determined and allocated to the reference point. A supplementary calibration information item which enables the image of the map to be calibrated in space coordinates is determined. A mobile radio telephone has a navigation device which is set up for carrying out the method.

Claims

1-18. -18. (canceled)

19. A method for the computer-aided determination of a position on a map, comprising:

storing a digitized image of a map in a data memory;

selecting at least one point of the image of the map;

determining space coordinates of at least one location which corresponds to the at least one selected point of the image of the map, and allocating the at least one selected point of the image of the map; and

determining a supplementary calibration information item which enables the image of the map to be calibrated in space coordinates.

20. The method as claimed in claim 19, further comprising:

at least partially reading out the image of the map from the data memory; and

displaying the image to a user.

21. The method as claimed in claim 20, further comprising determining space coordinates of an instantaneous location of the user.

22. The method as claimed in claim 21, further comprising marking the instantaneous location of the user in the image displayed.

23. The method as claimed in claim 19, further comprising storing a photographic image of a map.

24. The method as claimed in claim 19, further comprising storing the image as pixel graphics.

25. The method as claimed in claim 20, further comprising:

marking a point in the image displayed; and

selecting the marked point as the at least one selected point.

26. The method as claimed in claim 19, further comprising determining the space coordinates of an instantaneous location of a user as space coordinates of the at least one location which corresponds to the at least one selected point of the image of the map.

27. The method as claimed in claim 19, further comprising determining the space coordinates of the at least one location which corresponds to the at least one selected point of the image of the map from a user input.

28. The method as claimed in claim 19, further comprising determining the space coordinates of the at least one location which corresponds to the at least one selected point of the image of the map from features of the map.

29. The method as claimed in claim 19, wherein the supplementary calibration information is determined by:

selecting at least one additional point of the image of the map; and

determining space coordinates of at least one additional location which corresponds to the at least one selected additional point of the image of the map and allocating the space coordinates to the at least one selected additional point of the image of the map.

30. The method as claimed in claim 19, wherein the supplementary calibration information is determined by determining the scale and the geographic orientation of the image of the map with reference to space coordinates.

31. The method as claimed in claim 30, further comprising determining the scale and/or the geographic orientation from features of the map.

32. The method as claimed in claim 30, further comprising determining the scale and/or the geographic orientation with the aid of a user input.

33. The method as claimed in claim 21, wherein the space coordinates of the instantaneous location of the user are determined by a position measurement.

34. A navigation device comprising:

a data memory which stores a digitized image of a map;

a control device which is coupled to the data memory and which selects at least one point of the image of the map and allocates space coordinates to the at least one selected point of the image of the map;

a space coordinate determining unit which is coupled to the control device and determines space coordinates of at least one location which corresponds to the at least one selected point of the image of the map; and

a supplementary calibration information determining unit which is coupled to the control device and determines a supplementary calibration information item which enables the image of the map to be calibrated in space coordinates.

35. The navigation device as claimed in claim 34, further comprising a display unit which is coupled to the control device and displays the image of the map at least partially to a user,

wherein the space coordinate determining unit determines space coordinates of the instantaneous location of the user, and

wherein the control device causes the image of the map to be read at least partially out of the data memory and to be transmitted to the display unit and the instantaneous location of the user to marked in the image displayed by the display unit.

36. A mobile radio telephone comprising a navigation device as claimed in claim 34.

37. A navigation device comprising:

a data memory which stores a digitized image of a map;

a control means, which is coupled to the data memory, for selecting at least one point of the image of the map and for allocating space coordinates to the at least one selected point of the image of the map;

a space coordinate determining means, which is coupled to the control means, for determining space coordinates of at least one location which corresponds to the at least one selected point of the image of the map; and

a supplementary calibration information determining means, which is coupled to the control means, for determining a supplementary calibration information item which enables the image of the map to be calibrated in space coordinates.
