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.
Claims22
A method for the computer-aided determination of a position of a mobile device on a photographic image of a map, comprising:
- obtaining a digitized photographic image of the map, wherein the map is a non-geo-referenced map;
- storing the digitized photographic image of the map in a data memory;
- calibrating, by a processor, the digitized photographic image of the map in space coordinates by selecting at least one point of the digitized image of the map and a supplementary calibration information based on information provided by the photographic image of the map which enables the digitized image of the map to be calibrated in space coordinates;
- determining the position of the mobile device in space coordinates;
- and
- determining the position of the mobile device on the digitized photographic image of the map by mapping the position of the mobile device in space coordinates to a position on the digitized photographic image of the map based on the calibration of the digitized photographic image of the map in space coordinates.
