Abstract

Systems and methods are disclosed for performing three-dimensional video conferencing by capturing one or more registration marks; capturing a plurality of views of a scene; transmitting each view in a separate data stream to a remote location; receiving each data stream at the remote location and generating a plurality of images from the data streams; aligning one or more display planes in accordance with the one or more registration marks; and projecting the plurality of images onto one or more aligned display planes to show the 3D view of the scene at the remote location.

Claims

1. An apparatus for displaying three-dimensional images, comprising:

one or more cameras to capture one or more views of a scene and one or more registration marks;

a network to transmit each view in a separate data stream to a remote location;

a processor to receive each data stream at the remote location and generate from the data streams a plurality of images corresponding to the plurality of views; and

a display device coupled to the processor, the display device having one or more display planes aligned based on the registration marks, each display plane rendering an image generated by the processor.

2. The apparatus of claim 1, wherein the display device comprises a plurality of liquid crystal display (LCD) layer.

3. The apparatus of claim 1, wherein the display device comprises a plurality of retro-reflective layers.

4. The apparatus of claim 3, wherein the retro-reflective layers are angularly interspersed in a screen.

5. The apparatus of claim 1, wherein the display device projects the views onto air, mist or vapor.

6. The apparatus of claim 1, comprising a plurality of microphones to capture sounds.

7. The apparatus of claim 1, comprising a plurality of speakers at the remote location.

8. The apparatus of claim 1, wherein the display device comprises one or more projectors.

9. The apparatus of claim 8, comprising a motor coupled to each projector.

10. The apparatus of claim 1, comprising a motor to move each camera.

11. A method for performing three-dimensional video conferencing, comprising:

capturing one or more registration marks;

capturing a plurality of views of a scene;

transmitting each view in a separate data stream to a remote location;

receiving each data stream at the remote location and generating a plurality of images from the data streams;

aligning one or more display planes in accordance with the one or more registration marks; and

projecting the plurality of images onto one or more aligned display planes to show the 3D view of the scene at the remote location.

12. The method of claim 11, comprising:

projecting the views onto a plurality of liquid crystal display (LCD) layer.

13. The method of claim 11, comprising:

projecting the views onto a plurality of retro-reflective layers.

14. The method of claim 13, wherein the retro-reflective layers are interspersed in a screen.

15. The method of claim 11, comprising projecting the views onto air, mist or vapor.

16. The method of claim 11, comprising capturing sounds with a plurality of microphones.

17. The method of claim 16, wherein the microphones comprise a phased-array of microphones.

18. The method of claim 11, comprising playing sounds at the remote location with a plurality of speakers.

19. The method of claim 18, wherein the speakers comprise a phased-array of speakers.

20. The method of claim 11, wherein projecting the views comprises emitting light from a micro-mirror projector.
