Abstract

Methods and apparatuses for sharing a virtual image. An apparatus includes a virtual image creating unit which creates a moving virtual image, a virtual image registration requesting unit which requests a virtual image sharing server to register the virtual image created by the virtual image creating unit, and a virtual image sharing unit which receives the virtual image having the moving coordinates, which corresponds to current position information of the terminal device, from the virtual image sharing server.

Claims

1. A terminal device sharing a virtual image, comprising:

a virtual image creating unit configured to create a virtual image;

a virtual image registration requesting unit configured to transmit a request to register the virtual image created by the virtual image creating unit; and

a virtual image sharing unit configured to receive the virtual image having moving coordinates which correspond to current position information of the terminal device.

2. The terminal device of claim 1, wherein the virtual image creating unit uses a virtual image creating tool to create the virtual image on a displayed image using an augmented reality method.

3. The terminal device of claim 2, wherein the virtual image creating unit comprises:

a virtual image creator configured to create the virtual image on the displayed image using the augmented reality method;

an initial speed unit configured to output an initial speed (V) of the virtual image created by the virtual image creator;

an initial direction unit configured to output an initial direction (X, Y, Z coordinates) of the virtual image created by the virtual image creator; and

a movement time unit configured to output movement time information (t) of the virtual image created by the virtual image creator.

4. The terminal device of claim 2, wherein the virtual image creating unit comprises:

a virtual image creator configured to create the virtual image on the actually displayed image using the augmented reality method; and

a movement route unit configured to output movement route of the virtual image created by the virtual image creator.

5. The terminal device of claim 1, wherein the virtual image registration requesting unit maps the virtual image created by the virtual image creating unit, movement information of the created virtual image, and current position information of the terminal device, and requests a virtual image sharing server to register the virtual image.

6. The terminal device of claim 5, wherein the movement information comprises initial speed information, initial direction information, and movement time information, or comprises movement route information and movement time information.

7. The terminal device of claim 5, wherein the virtual image sharing unit transmits the current position information of the terminal device to the virtual image sharing server, receives a virtual image having moving coordinates within a certain region from a current position of the terminal device, and shares the virtual image.

8. The terminal device of claim 7, wherein the virtual image sharing unit modifies or deletes the received virtual image, retransmits the virtual image to the virtual image sharing server, receives the modified virtual image from the virtual image sharing server, and shares the virtual image.

9. A virtual image sharing system comprising:

a virtual image registering unit configured to register a virtual image according to a virtual image registration request from a virtual image registration requesting unit;

a moving coordinates calculating unit configured to calculate moving coordinates of the virtual image received from the virtual image registration requesting unit; and

a virtual image sharing unit configured to transmit the virtual image to a terminal device based on the moving coordinates calculated by the moving coordinates calculating unit.

10. The virtual image sharing system of claim 9, wherein the virtual image registering unit receives the virtual image, movement information and current position information of the virtual image from the virtual image registration requesting unit, and registers the virtual image.

11. The virtual image sharing system of claim 10, wherein the moving coordinates calculating unit calculates the moving coordinates of the virtual image, based on the virtual image, the movement information and the current position information of the virtual image received from the virtual image registration requesting unit.

12. The virtual image sharing system of claim 9, wherein the virtual image sharing unit transmits the virtual image having moving coordinates within a certain region from current position of the terminal device according to a virtual image request from the terminal device by using the moving coordinates calculated by the moving coordinates calculating unit.

13. The virtual image sharing system of claim 12, wherein the virtual image sharing unit transmits a modified virtual image to the terminal device and shares the virtual image.

14. The virtual image sharing system of claim 13, wherein the virtual image sharing unit transmits multi-view virtual images and modified virtual images according to a direction of the terminal device and shares the virtual images.

15. The virtual image sharing system of claim 13, further comprising:

a virtual image processing unit configured to reflect modified contents of the virtual images received from the terminal device on the corresponding virtual images, and transmits the modified virtual images to the virtual image sharing unit.

16. A method for sharing virtual images in a terminal device, comprising:

creating a virtual image on an actually displayed image;

mapping the created virtual image, movement information of the created virtual image, and current position information of the terminal device, and requesting a virtual image sharing server to register the virtual image; and

receiving the virtual image having moving coordinates corresponding to the current position information of the terminal device from the virtual image sharing server.

17. The method of claim 16, further comprising:

modifying or deleting the received virtual image;

retransmitting the virtual image to the virtual image sharing server; and

receiving the modified virtual image from the virtual image sharing server and sharing the virtual image.

18. The method of claim 16, wherein the movement information comprises initial speed information, initial direction information, and movement time information, or comprises movement route information and movement time information.

19. A method for sharing virtual images in a virtual image sharing system, comprising:

receiving a virtual image and movement information and current position information of the virtual image, and registering the virtual image;

calculating moving coordinates of the virtual image, based on the received virtual image, the movement information and the current position information of the virtual image, and storing the calculated moving coordinates; and

transmitting a virtual image within a certain region from current positions of a terminal device to the terminal device based on the calculated moving coordinates.

20. The method of claim 19, further comprising:

reflecting modified contents of the virtual images received from the terminal device on the corresponding virtual image; and

transmits the modified virtual image to the terminal device.
