Abstract

A solution for directing electromagnetic radiation, such as visible light, from multiple fields of view in differing directions to a single view point is provided. The radiation received from one or more fields of view is directed onto a first reflective surface, the radiation reflected off of the first reflective surface is then directed to a view point that comprises a transparent portion of the first reflective surface. In this manner, the invention enables the viewing and/or imaging of the radiation from any location in the full panorama at a single location.

Claims

1. A method of directing electromagnetic radiation from at least one of a plurality of fields of view to a view point, the method comprising:

providing a casing having a plurality of openings each having a shade to selectively allow electromagnetic radiation to pass therethrough, wherein each of the plurality of openings corresponds to one of the plurality of fields of view;

selectively opening one or more shades to pass electromagnetic radiation from a field of view through a corresponding opening;

directing electromagnetic radiation passing through each selected opening onto a first reflective surface; and

directing electromagnetic radiation reflected off of the first reflective surface to the view point, wherein the view point comprises a transparent portion of the first reflective surface.

2. The method of claim 1, wherein the selectively opening further includes opening a shade for an opening that corresponds to the selected at least one of the plurality of fields of view.

3. The method of claim 1, wherein the selectively opening further includes rotating a ring comprising at least one opening so that the at least one opening aligns with an opening of the casing that corresponds to the selected at least one of the plurality of fields of view.

4. The method of claim 1, further comprising adjusting a level of detail for the selected at least one of the plurality of fields of view.

5. The method of claim 1, further comprising directing the reflected electromagnetic radiation towards an imaging location having an imaging device.

6. The method of claim 5, further comprising projecting the reflected electromagnetic radiation onto the imaging device to form an image for each of the selected at least one of the plurality of fields of view.

7. The method of claim 6, further comprising combining each of the images generated from the selected at least one of the plurality of fields of view to generate a panoramic image.

8. A system for directing electromagnetic radiation from at least one of a plurality of fields of view to a view point, the system comprising:

a casing having a plurality of openings each having a shade to selectively allow electromagnetic radiation to pass therethrough, wherein each of the plurality of openings corresponds to one of the plurality of fields of view;

means for selectively opening one or more shades to pass electromagnetic radiation from a field of view through a corresponding opening;

means for directing electromagnetic radiation passing through each selected opening onto a concave reflective surface; and

a convex reflective surface for directing electromagnetic radiation reflected off of the concave reflective surface to the view point, wherein the view point comprises a transparent portion of the concave reflective surface.

9. The system of claim 8, wherein the shade comprises one of a cover, a shutter, or a liquid crystal panel.

10. The system of claim 8, wherein the casing comprises a rotatable ring.

11. The system of claim 8, wherein a combination of the plurality of fields of view comprises a panoramic field of view.

12. The system of claim 8, further comprising a system for adjusting a level of detail for the at least one of the plurality of fields of view.

13. A method of generating an image, the method comprising:

providing a casing having a plurality of openings each having a shade to selectively allow electromagnetic radiation to pass therethrough, wherein each of the plurality of openings corresponds to a plurality of fields of view;

selecting at least one of a plurality of fields of view to image;

selectively opening one or more shades of the plurality of openings that correspond to the selected at least one of a plurality of fields of view to image to pass electromagnetic radiation therethrough;

directing electromagnetic radiation passing through each selected orpening onto a first reflective surface;

directing electromagnetic radiation reflected off of the first reflective surface to a view point, wherein the view point comprises a transparent portion of the first reflective surface; and

generating the image based on the electromagnetic radiation received from each of the selected at least one of a plurality of fields of view.

14. The method of claim 13, further comprising adjusting a level of detail for the selected at least one of the plurality of fields of view.

15. The method of claim 13, further comprising repeating the directing for each of the selected at least one of the plurality of fields of view to generate the image.

16. The method of claim 13, wherein the generating of the panoramic image comprises combining each of the images generated from the selected at least one of the plurality of fields of view.

17. A panoramic imaging system comprising:

a casing having a plurality of openings each having a shade to selectively allow electromagnetic radiation to pass therethrough, wherein each of the plurality of openings corresponds to one of the plurality of fields of view;

means for selecting at least one of a plurality of fields of view to image;

means for selectively opening one or more shades to pass electromagnetic radiation from the selected fields of view through a corresponding opening;

means for directing electromagnetic radiation passing through each selected opening onto a first reflective surface;

a second reflective surface for directing electromagnetic radiation reflected reflected off of the first reflective surface to a view point, wherein the view point comprises a transparent portion of the first reflective surface; and

means for generating an image based on the electromagnetic radiation received from each of the selected at least one of a plurality of fields of view.

18. The system of claim 17, further comprising means for adjusting a level of detail for the selected at least one of the plurality of fields of view.

19. The system of claim 17, wherein the image generating means comprises means for combining each of the images generated from the selected at least one of the plurality of fields of view.
