Abstract

Disclosed herein is a method of generating multi-projection images. The method of generating multi-projection images includes controlling a plurality of the same types of filming devices so that the filming devices are disposed in a plurality of viewpoint directions, sending synchronized control signals to the plurality of the same types of filming devices and driving the plurality of the same types of filming devices in a synchronization state, and controlling the plurality of the same types of filming devices so that the filming devices perform filming operations in the plurality of viewpoint directions.

Claims

1. A method of generating multi-projection images, comprising:

controlling a plurality of same types of filming devices so that the filming devices are disposed in a plurality of viewpoint directions;

sending synchronized control signals to the plurality of the same types of filming devices and driving the plurality of the same types of filming devices in a synchronization state; and

controlling the plurality of the same types of filming devices so that the filming devices perform filming operations in the plurality of viewpoint directions.

2. The method of claim 1, wherein in disposing the plurality of the same types of filming devices, the plurality of the same types of filming devices forms an angle of view of 270 degrees or more.

3. The method of claim 2, wherein the plurality of the same types of filming devices is disposed so that angles of view of adjacent filming devices are overlapped.

4. The method of claim 3, wherein an overlap region between the angles of view of the adjacent filming devices is 13% to 17% of a total angle of view of each of the filming devices.

5. The method of claim 1, wherein the plurality of different types of filming devices is installed in a plurality of sliding bases and disposed at the specific angles through relative motions between the plurality of sliding bases.

6. The method of claim 1, wherein the plurality of the same types of filming devices comprise:

a main filming device disposed at a center;

a left filming device disposed on a left side of the main filming device; and

a right filming device disposed on a right side of the main filming device.

7. The method of claim 6, wherein if a focal distance of the main filming device is increased, the plurality of the same types of filming devices is disposed again so that an included angle between the main filming device and the left filming device and an included angle between the main filming device and the right filming device are reduced.

8. The method of claim 6, wherein:

a focal distance of the main filming device is 24 mm, and

a focal distance of each of the left filming device and the right filming device is 16 mm.

9. The method of claim 1, further comprising mapping images captured by the plurality of the same types of filming devices to a spherical space or cylindrical space and generating images of respective planes.

10. A system for generating multi-projection images, comprising:

a plurality of same types of filming devices disposed in a plurality of viewpoint directions and configured to perform filming operations in the plurality of viewpoint directions in a state in which the same types of filming devices have been synchronized; and

a synchronization control device configured to synchronize the plurality of the same types of filming devices by sending synchronized control signals to the plurality of the same types of filming devices.

11. The system of claim 10, wherein:

adjacent filming devices of the plurality of the same types of filming devices are disposed to form a specific included angle, and

the plurality of the same types of filming devices implements an angle of view of 270 degrees or more.

12. The system of claim 10, further comprising:

a plurality of sliding bases configured to have the plurality of the same types of filming devices installed in the respective sliding bases; and

a rig configured to have the plurality of sliding bases rotatably movable in the rig,

wherein the plurality of the same types of filming devices is disposed in the plurality of viewpoint directions through relative motions between the plurality of sliding bases.

13. The system of claim 12, wherein the rig comprises:

a base plate configured to form a basic body; and

a plurality of punched units formed in the base plate and configured to have the plurality of sliding bases movable in the punched units.

14. The system of claim 10, wherein the plurality of the same types of filming devices comprises:

a main filming device disposed at a center;

a left filming device disposed on a left side of the main filming device; and

a right filming device disposed on a right side of the main filming device.

15. The system of claim 10, further comprising an image processing device configured to map images, captured by the plurality of the same types of filming devices, to a spherical space or cylindrical space and to generate images of respective planes.
