Abstract

The systems and methods described herein include, among other things, a technique for real time image transmission from a remote sensor head having plural fields of view.

Claims

1. An imaging device comprising:

an outer housing,

an inner sensor body,

a plurality of image sensors disposed on the surface of the inner sensor body, each image sensor having a field of view and recording an image in a respective field of view, the image being combinable with one or more other images to form a scene, wherein the scene has a resolution, and

a processor for selectively adjusting the resolution of at least a portion of the scene.

2. The device of claim 1, further comprising a transceiver in connection with the processor, for transmitting image data to a remote location.

3. The device of claim 1, wherein the plurality of image sensors are positioned such that their fields of view overlap.

4. The device of claim 1, further comprising a memory containing a table mapping each of a plurality of image points from the scene to a pixel of at least one image sensor.

5. The device of claim 4, further comprising a display-driver, wherein the display-driver references the table to determine which pixel from which image sensor to use to display a selected section of the scene.

6. The device of claim 1, wherein the plurality of image sensors are positioned to capture at least a hemispherical region within the fields of view of the plurality of image sensors.

7. The device of claim 1, wherein the plurality of image sensors record an image at a high resolution.

8. The device of claim 1, wherein the processor decreases the resolution of the scene.

9. The device of claim 1, wherein the processor decreases the resolution of a portion of the scene.

10. The device of claim 9, wherein the processor selectively decreases the resolution of a portion of the scene that is substantially static.

11. The device of claim 9, wherein a user selects an area of the scene, and the processor decreases the resolution of the unselected portion of the scene.

12. The device of claim 1, further comprising an image multiplexer for receiving the images recorded by the image sensors.

13. The device of claim 12, wherein the image multiplexer merges the images and creates a scene.

14. The device of claim 12, further comprising a memory for storing the images received by the image multiplexer.

15. The device of claim 1, further comprising a memory for storing the images recorded by the sensors.

16. The device of claim 1, wherein the outer housing is robust, such that it remains intact upon impact with a hard surface.

17. The device of claim 1, wherein the processor selectively adjusts the resolution to allow for real-time transmission of image data.

18. The device according to claim 1, wherein the outer housing comprises a housing dimensionally adapted to fit within the hand of a person.

19. The device according to claim 1, further comprising a mount for mounting the housing to a structure.

20. The device of claim 8, wherein the processor includes means for decreasing the resolution of portions of the image to provide a user sufficient resolution for situational awareness.

21. The device of claim 1, further comprising a grid pattern disposed within the fields of view of at least two sensors for allowing said at least two sensors to capture an image of the grid pattern appearing in its respective field of view.

22. The device of claim 21, further comprising a calibration mechanism for processing said captured images to identify overlapping regions within the fields of view of a plurality of sensors and for generating a look up table correlating pixels in a panoramic image with pixels in the plurality of sensors.

23. An imaging device comprising:

an outer housing,

an inner sensor body,

at least one image sensor disposed on the surface of the inner sensor body, the image sensor having a field of view and recording an image in the field of view, wherein the image has a resolution, and

a processor for selectively adjusting the resolution of at least a portion of the image.

24. The device of claim 23, wherein the image sensor records an image at a high resolution.

25. The device of claim 23, wherein the processor decreases the resolution of the image.

26. The device of claim 23, wherein the processor decreases the resolution of a portion of the image.

27. The device of claim 26, wherein the processor selectively decreases the resolution of a portion of the image that is substantially static.

28. The device of claim 26, wherein a user selects an area of the image, and the processor decreases the resolution of the unselected portion of the image.

29. The device of claim 23, wherein the processor selectively adjusts the resolution to allow for real-time transmission of image data.

30. The device of claim 29, wherein the outer housing is robust, such that it remains intact upon impact with a hard surface.
