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, comprising:

a culling area determination unit to determine a culling area based on road information;

a data conversion unit to convert data of a portion of each object displayed on the culling area; and

a display unit to display the portion of the each object based on the converted data;

wherein the culling area determination unit comprises;

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

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

wherein the road information includes information about the width of the road and information about the predetermined weight for the determined width,

wherein the culling area determination unit determines the culling area using both information about the width of the road and information about the predetermined weight for the determined width, and

wherein the data conversion unit converts the data to enable the portion of the each object to be blended or removed.

2. The display system of claim 1, wherein the road information includes information about at least one of a width and a lane of a road, and

wherein, as 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 1, wherein the culling area determination unit determines an area corresponding to a virtual 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 determines a rectangular area as the culling area, the rectangular area having a weighted width as a side, and

wherein the weighted width is generated by applying the predetermined weight to the determined width.

5. The display system of claim 1, wherein the culling area determination unit determines a circular area as the culling area, the circular area having a weighted width as a radius, and

wherein the weighted width is generated by applying the predetermined weight to the determined width.

6. 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 starting from ground level and having a weighted width as a side, and

wherein the weighted width is generated by applying the predetermined weight to the determined width.

7. 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 starting from ground level and being based on a circular figure having a weighted width as a radius, and

wherein the weighted width is generated by applying the predetermined weight to the determined width.

8. The display system of claim 1, wherein the culling area is determined based on the road information and a location of a vehicle, and the culling area determination unit changes the culling area based on a change of the location of the vehicle.

9. The display system of claim 1, further comprising:

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

wherein the data conversion unit differently converts data of the each object depending on the divided area.

10. The display system of claim 9, wherein the different conversion includes data conversion to remove a portion of the each object and data conversion to blend at least the portion of the each object.

11. A display method, comprising:

determining a culling area based on road information;

converting data of a portion of each object displayed on the culling area; and

displaying the portion of the each object based on the converted data;

wherein the determining comprises;

determining a width of a road; and

providing a predetermined weight for the determined width,

wherein the road information includes information about a width of the road and information about a predetermined weight for the determined width,

wherein the culling area is determined by using both information about the width of the road and information about the predetermined weight for the determined width, and

wherein the converting converts the data to enable the portion of the each object to be blended or removed.

12. The display method of claim 11, wherein the road information includes information about at least one of a width and a lane of a road, and

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

13. The display method of claim 11, wherein the determining determines an area corresponding to a generable virtual figure as the culling area based on the road information.

14. The display method of claim 11, wherein the determining of the culling area determines a rectangular area as the culling area, the rectangular area having a weighted width as a side, and

wherein the weighted width is generated by applying the predetermined weight to the determined width.

15. The display method of claim 11, wherein the determining of the culling area determines a circular area as the culling area, the circular area having a weighted width as a radius, and

wherein the weighted width is generated by applying the predetermined weight to the determined width.

16. The display method of claim 11, wherein the determining of the culling area determines an area corresponding to a space figure as the culling area, the space figure starting from ground level and having a weighted width as a side, and

wherein the weighted width is generated by applying the predetermined weight to the determined width.
