Abstract
Abstract From navigation data of a vehicle there is formed an indication signal which is superposed on an image of the local environment which is generated by an image pick-up unit. The combination is displayed on a display unit.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
55 words
A method of displaying navigation data for a vehicle in an image of the local vehicle environment, characterized in that an image of the local vehicle environment is generated by an image pick-up unit, which image is displayed on a display unit, an indication signal formed from the navigation data being superposed on the image.
Claim 2
Independent Claim
55 words
A method of displaying navigation data for a vehicle in an image of the local vehicle environment, characterized in that an image of the local vehicle environment is generated by an image pick-up unit, which image is displayed on a display unit, an indication signal formed from the navigation data being superposed on the image.
Claim 3
Dependent Claim
61 words
A method as claimed in Claim 1 where the navigation data is generated by a navigation system on the basis of measurement data from sensors and/or topographic data from a data structure, characterized in that before formation of the indication signal, the navigation data is transformed in conformity with a position of the image pick-up unit with respect to the environment.
Claim 4
Dependent Claim
21 words
A method as claimed in Claim 2, characterized in that the navigation data is transformed by way of a perspective transformation.
Claim 5
Independent Claim
28 words
A method as claimed in any one of the Claims 1 to 3, characterized in that the display unit displays the navigation data so as to be distinct.
Claim 6
Independent Claim
76 words
A method as claimed in any one of the Claims 1 to 4, where the navigation data is generated by a navigation system on the basis of measurement data from sensors and topographic data from a data structure in which roads are represented by coordinates of their centre lines, characterized in that prior to the formation of the indication signal from the navigation data the representation of the roads is converted into a representation by polygons.
Claim 7
Dependent Claim
93 words
A navigation system suitable for performing a method as claimed in any one of the Claims 1 to 5, characterized in that the navigation system comprises an image pick-up unit which generates an image of the local environment, a transformation module for transforming navigation data generated by the navigation system, a video generator for generating an indication signal from the transformed navigation data, a combination module for combining the image of the environment and the indication signal so as to form a combined signal, and a display unit for displaying the combined signal.
Claim 8
Dependent Claim
11 words
A vehicle comprising a navigation system as claimed in Claim 6.
