Abstract

A multiple position camera apparatus and method for a three-dimensional computer controlled telepresence camera system useful in surrogate travel type applications. In one embodiment, it enables a telepresence application provider to form multi-view application specific stored image sequences from up to six orthogonally positioned cameras. It furthermore enables a telepresence user to subsequently retrieve for remote viewing particular subsets of the available image sequences and/or groups of sequences via a monitoring and display system. A viewing procedure provides the user with the ability to proceed spatially and/or contiguously along any camera to camera direction. It further uses a wire cage to enable the definition and setting of the field of view of each camera.

Claims

1. A camera apparatus comprising:

a plurality of cameras,

each of said cameras having a camera input, and a camera output, and being positioned at a position to monitor a viewing portion of a total field of view, said viewing portion of each camera of said plurality of cameras being space-contiguous with the viewing portion of at least one other camera of said plurality of cameras;

a processing device having means for receiving, marking and storing said camera output of each of said cameras; and

a wire cage surrounding said cameras and having a plurality of wire faces, each of said wire faces being positioned opposite to said input of one of said cameras, wherein said cameras are movable with respect to and independent of said wire cage and each of said wire faces defines said viewing portion of said input of one of said plurality of cameras for making said camera output.

2. An apparatus as recited in claim 1 wherein said wire cage is formed with wire having a diameter of one eighth of an inch.

3. An apparatus as recited in claim 1 wherein said wire cage is formed with wire-like material having repeated color bands of red, blue and yellow.

4. An apparatus as recited in claim 3 wherein said processing device recognizes said repeated color bands from which it determines a desired viewing portion for each of said cameras.

5. A camera apparatus comprising:

a plurality of cameras,

each of said cameras having a camera input, and a camera output, and being positioned at a position to monitor a viewing portion of a total field of view, said viewing portion of each camera of said plurality of cameras being space-contiguous with the viewing portion of at least one other camera of said plurality of cameras; and

a processing device having means for receiving, marking and storing said camera output of each of said cameras, wherein said cameras are positioned to surround an object being viewed, and said input of each of said cameras is positioned to look inward towards said object, and

a wire cage surrounding said object and being surrounded by said cameras wherein said cameras are movable with respect to and independent of said wire cage, and said wire cage has a plurality of faces, with each of said faces being positioned essentially opposite to said input of one of said cameras, and wherein each of said faces defines said viewing portion of each of said cameras for marking said camera output.

6. An apparatus as recited in claim 5 wherein said wire cage has a wire periphery, said wire periphery including at least one image plate, said image plate being included in at least one of said viewing portions.

7. A view monitoring method employing a plurality of cameras having a total field of view, each of said cameras having a camera input, said method comprising the steps of:

positioning each of said cameras to monitor at said input a viewing portion of said total field of view such that each said viewing portion is space-contiguous with the viewing portion of at least one other of said cameras;

mounting said plurality of cameras such that in an XYZ rectangular coordinate system at least one said viewing portion is essentially facing an X-Y plane, a second viewing portion is essentially facing an X-Z plane, and a third viewing portion is essentially facing the Y-Z plane;

surrounding said cameras with a wire cage having a plurality of wire faces;

positioning one of said wire faces substantially opposite to said input of each of said cameras wherein said cameras are movable with respect to and independent of said wire cage and each of said wire faces identifies a different viewing portion; and

setting said viewing portion of said input of each of said cameras in correspondence with one of said wire faces for marking said camera input.

8. A view monitoring method employing a plurality of cameras having a total field of view, each of said cameras having a camera input, said method comprising the steps of:

positioning each of said cameras to monitor at said input a viewing portion of said total field of view such that each said viewing portion is space-contiguous with the viewing portion of at least one other of said cameras;

mounting said plurality of cameras such that in an XYZ rectangular coordinate system at least one said viewing portion is essentially facing an X-Y plane, a second viewing portion is essentially facing an X-Z plane, and a third viewing portion is essentially facing the Y-Z plane, in which said total field of view includes an object surrounded by said cameras, and said input of each of said cameras is positioned to look inward toward said object;

surrounding said object with a wire cage mounted between said object and said cameras, said wire cage having a plurality of faces;

positioning each of said faces opposite to said input of one of said plurality of cameras wherein said cameras are movable with respect to and independent of said wire cage; and

setting said viewing portion of said input of each of said cameras in correspondence with one of said faces for marking said camera input.

9. A method as recited in claim 8 wherein said wire cage has a wire periphery, said wire periphery including at least one image plate, said image plate being included in at least one of said viewing portions.
