Abstract

A video system employs three or four panoramic optical devices, fixedly mounted on a stationary support, to provide, without movement, a coherent, visually perceptible stereoscopic image of a common field of view.

Claims

1. A panoramic, semispherical, stereoscopic video system, comprising:

support means;

camera means, mounted by said support means, for collecting images and converting them to representative electrical signals;

a multiplicity of three or four optical devices, fixedly mounted at mutually spaced locations in a multilateral arrangement on said support means, for producing a said multiplicity of panoramic, semispherical images of a common field of view, said optical devices having mutually parallel panoramic axes and being optically connected to said camera means for delivering thereto the image viewed by said each optical device; and

electronic data processing means operatively connected to said camera means for receiving said representative electrical signals therefrom, and including programming means for converting said received electrical signals for the production of at least one coherent, visually perceptible, stereoscopic image of said common field of view.

2. The system of claim 1 wherein said camera means is also fixedly mounted by said support means.

3. The system of claim 1 wherein said camera means comprises a charge coupled device image sensor.

4. The system of claim 3 wherein said camera means comprises a multiplicity of charge coupled device cameras operatively connected to said electronic data processing means, one of said cameras being optically connected to each of said optical devices.

5. The system of claim 1 comprising three of said optical devices, so mounted in a triangular relationship to one another.

6. The system of claim 5 wherein said optical devices lie substantially on a common plane to which said panoramic axes are normal, and wherein said triangular relationship is substantially equilateral.

7. The system of claim 1 wherein said field-of-view image produced by each of said optical devices is a 360°

panorama.

8. The system of claim 1 wherein said field-of-view image produced by each of said optical devices encompasses at least about a 90°

view taken with reference to said panoramic axis thereof.

9. The system of claim 1 wherein said field-of-view image produced by each of said optical devices encompasses at least about a full hemisphere.

10. The system of claim 1 wherein each of said optical devices comprises a structure that includes a section of generally conic form and that provides an outer, image-transmitting surface portion.

11. The system of claim 10 wherein said outer surface portion of said each optical device is arcuately concave in planes parallel to said panoramic axis thereof.

12. The system of claim 10 wherein said section of generally conic form extends about the entire periphery of said structure.

13. The system of claim 10 wherein said section of generally conic form terminates in a vertex at one end of said structure and on said panoramic axis thereof.

14. The system of claim 13 wherein said vertex comprises an image-transmitting optical aperture, enabling said each optical device to produce at least a substantially hemispheric field-of-view image.

15. The system of claim 1 wherein each of said optical devices comprises a panoramic refracting optic.

16. The system of claim 1 wherein said programming means functions to select dynamically, from among said signals received from said camera means, signals that represent images produced, at any given time, by only two of said optical devices.

22. The system of claim 1 additionally including a robot having a fixedly disposed head member on which said support means is also fixedly disposed.

23. The system of claim 22 further including a remote monitor operatively connected to said electronic data processing means for viewing of said stereoscopic image of said common field of view.

24. The system of claim 23 wherein said remote monitor is movable for selectively controlling the visual scope of said common field of view without movement of said head member of said robot or said support means.

25. The system of claim 23 wherein said remote monitor is constructed to be worn on the head of a human operator.

17. A panoramic, semispherical, stereoscopic video system, comprising:

support means;

camera means, mounted by said support means, for collecting images and converting them to representative electrical signals;

a multiplicity of three or four optical devices, fixedly mounted at mutually spaced locations in a multilateral arrangement on said support means, for producing a said corresponding multiplicity of panoramic, semispherical images of a common field of view, each of said optical devices being optically connected to said camera means for delivering thereto the image viewed by said each optical device; and

electronic data processing means operatively connected to said camera means for receiving said representative electrical signals therefrom, and including programming means for converting said received electrical signals for the production of at least one coherent, visually perceptible, stereoscopic image of said common field of view, said programming means functioning to select dynamically, from among said signals received from said camera means, signals that represent images produced, at any given time, by only two of said optical devices.

18. The system of claim 17 wherein said camera means comprises a multiplicity of charge coupled device cameras operatively connected to said electronic data processing means, one of said cameras being optically connected to each of said optical devices.

19. The system of claim 17 wherein said optical devices lie substantially on a common plane, and said multilateral relationship is substantially equilateral.

20. The system of claim 17 wherein each of said optical devices comprises a structure that includes a section of generally conic form and that provides an outer, image-transmitting surface portion, and wherein said outer surface portion of said each optical device is arcuately concave in planes parallel to a panoramic axis of said each device about which said section of said structure extends.

21. The system of claim 17 wherein said section of generally conic form extends about the entire periphery of said structure, wherein said section of generally conic form terminates in a vertex at one end of said structure, comprising an image-transmitting optical aperture, and wherein each of said optical devices comprises a panoramic refracting optic.

26. The system of claim 17 additionally including a robot having a fixedly disposed head member on which said support means is also fixedly disposed.

27. The system of claim 26 further including a remote monitor operatively connected to said electronic data processing means for viewing of said stereoscopic image of said common field of view.

28. The system of claim 27 wherein said remote monitor is movable for selectively controlling the visual scope of said common field of view without movement of said head member of said robot or said support means.

29. The system of claim 27 wherein said remote monitor is constructed to be worn on the head of a human operator.
