Abstract

A system and method of displaying a three-dimensional (3D) map based on road information. A display system, including: a culling area determination unit to determine a culling area based on road information; a data conversion unit to convert data of at least a portion of objects displayed on the culling area; and a display unit to display at least the portion of the objects based on the converted data.

Claims

1. A display system for a vehicle, comprising a processor configured to implement:

a culling area determination unit to determine a culling area based on a location of the vehicle;

a data conversion unit to convert data of at least a portion of objects displayed on the culling area;

a display unit to display at least the portion of the objects based on the converted data; and

an area division unit to divide the culling area into a plurality of culling areas,

a width determination unit to determine the width of the road;

a weight providing unit to provide the predetermined weight for the determined width;

wherein the culling area determination unit changes the culling area based on a change of the location of the vehicle and information about the width of the road and information about the predetermined weight for the determined width, and the data conversion unit differently converts data of an object depending on the divided culling area.

2. The display system of claim 1, wherein the culling area determination unit determines the culling area based on road information,

wherein the road information includes information about at least one of a width and a lane of a road, and

the width of the road increases or a number of lanes of the road increases, the culling area is determined to be larger.

3. The display system of claim 2, wherein the culling area determination unit determines an area corresponding to space figure capable of being generated as the culling area based on the road information.

4. The display system of claim 1, wherein the culling area determination unit comprises a width determination unit to determine a width of a road.

5. The display system of claim 4, wherein the culling area determination unit comprises a weight providing unit to provide a predetermined weight for the determined width.

6. The display system of claim 5, wherein the culling area determination unit determines a rectangular area as the culling area, the rectangular area having the weighted width as a side.

7. The display system of claim 5, wherein the culling area determination unit determines a circular area as the culling area, the circular area having the weighted width as a radius.

8. The display system of claim 1, wherein the culling area determination unit determines an area corresponding to a space figure as the culling area, the space figure comprises a 3D space figure.

9. The display system of claim 5, wherein the culling area determination unit determines an area corresponding to a space figure as the culling area, the space figure starts from ground level and is based on a circular figure having the weighted width as a radius.

10. The display system of claim 1, wherein the data conversion unit converts the data to enable at least a portion of each of at least the portion of the objects to be removed.

11. The display system of claim 1, wherein the data conversion unit converts the data to enable at least a portion of each of at least the portion of the objects to be blended.

12. The display system of claim 1, wherein the different conversion includes data conversion to remove at least a portion of objects and data conversion to blend at least the portion of the objects.

13. The display system of claim 1, wherein the culling area determination unit determines an area corresponding to a space figure as the culling area having a center corresponding to the location of the vehicle.

14. The display system of claim 1, wherein the area division unit divides the culling area based on a distance from the vehicle.

15. The display system of claim 1, wherein the culling area determination unit comprises the weight providing unit provides different weights to the divided culling areas.

16. A display method for a vehicle, comprising:

determining a culling area based on a location of the vehicle;

dividing the culling area into a plurality of culling areas;

differently converting data of at least a portion of objects displayed on the divided culling area depending on the divided culling area; and

displaying at least the portion of the objects based on the converted data,

determining the width of the road;

providing the predetermined weight for the determined width;

wherein the determining a culling area changes the culling area based on a change of the location of the vehicle and information about the width of the road and information about the predetermined weight for the determined width.

17. The display method of claim 16, wherein the determining a culling area determines the culling area based on road information,

wherein the road information includes information about at least one of a width and a lane of a road, and the width of the road increases or a number of lanes of the road increases, the culling area is determined to be larger.

18. The display method of claim 17, wherein the determining a culling area determines an area corresponding to a space figure capable of being generated as the culling area based on the road information.

19. The display method of claim 16, wherein the determining a culling area comprises:

determining a width of a road; and

providing a predetermined weight for the determined width.

20. The display method of claim 19, wherein the determining a culling area determines a rectangular area as the culling area, the rectangular area having the weighted width as a side.

21. The display method of claim 19, wherein the determining of the culling area determines a circular area as the culling area, the circular area having the weighted width as a radius.

22. The display method of claim 16, wherein the determining of the culling area determines an area corresponding to a space figure as the culling area, the space figure comprises a 3D space figure.

23. The display method of claim 16, prior to the differently converting data of at least a portion of objects, further comprising:

determining areas, each of the areas corresponding to a space figure, as the divided culling areas, each of the divided culling areas having a center corresponding to the location of the vehicle.
