Abstract

A method for displaying a virtual image of three dimensional objects in an area using stereo recordings of the area for storing a pixel and a height for each point of the area. A method is obtained of enabling displaying of vertical surfaces or even slightly downwards and inwards inclined surfaces. Stereo recordings from at least three different stereo recordings of different solid angles are used. For each different solid angle at least one data base including data about texture and height pixel point wise is established. Data for displaying the virtual image are combined from the different data bases in dependence of the direction in which the virtual image is to be displayed.
