Embodiment Construction

[0022] figure 1 and figure 2 A navigation system 1 is shown, which has a display 10 . Display screen 10 is arranged by way of example in projection view 11 of virtual camera 12 and is depicted in a schematic diagram as a component of navigation system 1 . The image visible to the viewer in the display screen 10 of the map display 13 corresponds to the projected viewing angle 11 from which the virtual camera 12 captures the image. If a viewer looks at display screen 10 , map display 13 is displayed with the same viewing angle as the virtual camera 12 captures the map display from projected viewing angle 11 . In this case, the projection angle of view 11 is only inclined at the indicated viewing angle α, wherein the virtual camera 12 is arranged centrally above the visually represented three-dimensional map display 13 .

[0023] If the display screen 10 of the navigation system 1 is arranged, for example, in the middle of the instrument panel of the vehicle, the driver or pa...

Abstract

The invention relates to a navigation system (1) and a method for operating the navigation system (1) with a display screen (10) via which a map display (13) is three-dimensionally presented. In order to provide a navigation system with an improved map display in the display screen of the navigation system so that the viewer perceives the three-dimensional map display better at an oblique angle to the display screen, it is provided that the map display (13) is based on The projection viewing angle (11) of the virtual camera (12), by which the map display (13) is presented as a virtual image, wherein the projection viewing angle (11) of the virtual camera (12) is adjusted to at least one of the display screens (10) The viewing angle (14) of the observer (15).

Description

technical field [0001] The invention relates to a navigation system and a method for operating a navigation system with a display screen, by means of which a map display can be represented in three dimensions. Background technique [0002] The navigation system can include a display, which presents a map display in three dimensions and is described as a dual-view display. For example, according to US 2009 / 0079680 A1, a dual-view display is known, in which the projection is based on a virtual camera arranged centrally in front of the display, which presents the projection perspective depending on its position. If the viewer looks obliquely at the display screen, the viewer's viewing angle which deviates from the central projection viewing angle is compensated in the display screen by means of hardware tools, however, this results in higher costs when constructing such a display screen. [0003] From US 2002 / 0097332 A1 a system is known for providing a visual correction of a ...
