Navigation device for a movable object and method for generating a display signal for a navigation device for a movable object
First Claim
1. A navigation device for a movable object, comprising:
- a data provider to provide data of a three-dimensional navigation map having one or more towering map objects; and
a processor to receive data of a three-dimensional navigation map from the data provider, the received data of an area surrounding an ascertained position of a movable object, and to generate a display signal of the three-dimensional navigation map for a display device;
wherein the processor generates the display signal so that the navigation map is displayed as if viewed from a view position that is located above the navigation map and is a function of the ascertained position of the movable object,wherein the processor dynamically alters a height of at least one towering map object in the navigation map as a function of a distance of the towering map object to the view position, wherein the altered height of the at least one towering map object decreases as the distance of the at least one towering map object to the view position decreases.

Abstract
A navigation device for a movable object includes a data provider and a processor that provides a three-dimensional navigation map having towering map objects. Based on an ascertained position of a movable object, the processor receives a three-dimensional navigation map having towering map objects of an area surrounding the movable object and provides navigation map to a display device so that the navigation map is reproducible by the display device in a manner viewed from a view position which is located above the navigation map and is a function of the ascertained position of the movable object. The processor dynamically alters a height of a towering map object in the navigation map as a function of a distance of the towering map object to the view position.

16. A method for generating a display signal for a navigation device for a movable object, the method comprising:
-
receiving data corresponding to a three-dimensional navigation map having at least one towering map object of an area surrounding a movable object based on an ascertained position of the movable object; and generating a display signal representing the navigation map, so that the navigation map is viewed from a view position that is located above the navigation map and is a function of the ascertained position of the movable object, and a height of at least one towering object in the navigation map is altered dynamically as a function of a distance of the towering object to the view position, wherein the altered height of the at least one towering map object decreases as the distance of the at least one towering map object to the view position decreases; and transmitting the display signal representing the navigation map to a display device for display of the navigation map.

17. A non-transitory computer readable medium including instructions which when executed on a programmable processor, induce the processor to carry out the steps of a method, the method comprising:
-
receiving data corresponding to a three-dimensional navigation map having at least one towering map object of an area surrounding a movable object based on an ascertained position of the movable object; and generating a display signal representing the navigation map, so that the navigation map is viewed from a view position that is located above the navigation map and is a function of the ascertained position of the movable object, and a height of at least one towering object in the navigation map is altered dynamically as a function of a distance of the towering object to the view position, wherein the altered height of the at least one towering map object decreases as the distance of the at least one towering map object to the view position decreases; and transmitting the display signal representing the navigation map to a display device for display of the navigation map.
