US 2014/0368496 A1 · 3-DIMENSIONAL MAP VIEW WITH BACKGROUND IMAGES

Abstract

Techniques for generating a 3-dimensional map view of a navigation system are disclosed. A position module determines a position of a user to which the 3-dimensional map view is to be displayed, a viewing direction and elevation for the user. A map viewer generates the 3-dimensional map view of the map data, wherein for objects located within a predefined distance to the position of the user the position and the representation of each object is calculated taking into account the viewing direction and the elevation, wherein for objects located outside the predefined distance at least one group of objects, to which the objects belong, is identified, and for each identified group the background image is selected and displayed in which the 3-dimensional objects of the identified group are shown from the determined viewing direction and elevation. A display device displays the generated map view.

Dependent claims

A method for generating a 3-dimensional map view of a navigation system, the method comprising:

determining a position, a viewing direction, and an elevation to which the 3-dimensional map view is to be displayed;
for each object in a plurality of objects:
determining whether the object is within a predefined distance relative to the position, and
if the object is within a predefined distance relative to the position, then calculating a representation of each object based at least in part on the viewing direction and the elevation, or
if the object is not within a predefined distance relative to the position, then
identifying an object group in a plurality of object groups to which the object belongs, and
selecting a background image from a plurality of background images associated with the object group based at least in part on the viewing direction and the elevation;
generating the 3-dimensional map view based on at least one calculated representation and at least one selected background image;
and
displaying the generated 3-dimensional map view.

A navigation system for generating a 3-dimensional map view, the navigation system comprising:

a database including geographic map data, the geographic map data further comprising a plurality of objects;
a positioning module that determines a position, a viewing direction, and an elevation to which the 3-dimensional map view is to be displayed;
a map viewer that, for each object in the plurality of objects:
determines whether the object is within a predefined distance relative to the position, and
if the object is within a predefined distance relative to the position, then calculates a representation of each object based at least in part on the viewing direction and the elevation, or
if the object is not within a predefined distance relative to the position, then
identifies an object group in a plurality of object groups to which the object belongs;
and
selects a background image from a plurality of background images associated with the object group based at least in part on the viewing direction and the elevation, and
generates the 3-dimensional map view based on at least one calculated representation and at least one background;
and
a display that displays the generated 3-dimensional map view.
