Abstract

A motion capture system includes motion capture cameras positioned in various locations and orientations with respect to a motion capture volume. The motion capture system includes a host computing device that is operatively coupled with the motion capture cameras. The host computing device remotely controls operation of the motion capture cameras to record movement within the motion capture volume. At least one of the motion capture cameras includes a user-interface that is operable by a user to remotely initiate a control operation of the host computing device.

Claims

1. A motion capture system comprising:

a plurality of motion capture cameras positioned in various locations and orientations with respect to a motion capture volume;

a host computing device, operatively coupled with the plurality of motion capture cameras, to remotely control operation of the plurality of motion capture cameras to record movement within the motion capture volume; and

at least one of the plurality of motion capture cameras including a user-interface operable by a user to remotely initiate a control operation of the host computing device.

2. The system of claim 1, where the control operation includes displaying a view of the capture volume from the motion capture camera that initiated the control operation on a display device operatively coupled with the host computing device.

3. The system of claim 2, where the control operation prompts the host computing device to control the motion capture camera that initiated the control operation to provide a user-perceivable indication that the view from the motion capture camera is selected for display.

4. The system of claim 1, where a display device operatively coupled with the host computing device presents a view of the capture volume from each of the plurality of motion capture cameras, and the control operation includes enlarging the view of the capture volume from the motion capture camera that initiated the control operation relative to the views from the other motion capture cameras.

5. The system of claim 1, where the control operation prompts the host computing device to adjust a state of the motion capture camera that initiated the control operation.

6. The system of claim 5, where adjusting the state includes adjusting a focus of the motion capture camera that initiated the control operation.

7. The system of claim 5, where adjusting the state includes adjusting a frame rate of the motion capture camera that initiated the control operation.

8. The system of claim 5, where adjusting the state includes changing an operating mode of the motion capture camera that initiated the control operation.

9. The system of claim 8, where changing the operating mode includes physically interchanging an optical component positioned in a light path upstream of an image sensor of the motion capture camera that initiated the control operation.

10. The system of claim 8, where the control operation that prompts the host computing device to change the operating mode of the motion capture camera that initiated the control operation also prompts the host computing device to change an operating mode of the other motion capture cameras differently than the operating mode of the motion capture camera that initiated the control operation.

11. A motion capture camera apparatus comprising:

an image sensor configured to receive incident light from a capture volume and thereby generate an image of the capture volume;

a controller, operable to receive a control operation from a host computing device to record movement within the capture volume; and

a user interface operable by a user to remotely initiate a control operation of the host computing device.

12. The apparatus of claim 11, where the control operation prompts the host computing device to adjust a state of the motion capture camera apparatus.

13. The apparatus of claim 12, where adjusting the state includes at least one of adjusting a focus of the motion capture camera apparatus, adjusting a frame rate of the motion capture camera apparatus, and changing an operating mode of the motion capture camera apparatus.

14. The apparatus of claim 11, where the user interface include a multi-state actuator, the multi-state actuator adjustable to a first state to remotely initiate a first control operation of the host computing device and adjustable to a second state to remotely initiate a second control operation of the host computing device different from the first control operation.

15. The apparatus of claim 14, where the multi-state actuator includes a depressible button, where the first state includes a single tap of the depressible button, and where the second state includes a double tap of the depressible button.

16. The apparatus of claim 14, where the multi-state actuator includes a selector wheel, where the first state includes rotating the selector wheel to a first position, and where the second state includes rotating the selector wheel to a second position different from the first position.

17. A method for controlling a host computing device operatively coupled to a plurality of motion capture cameras, comprising:

receiving a first control operation remotely initiated by user input to a user interface of a first motion capture camera of the plurality of motion capture cameras; and

adjusting a state of the first motion capture camera in accordance with the first control operation.

18. The method of claim 17, further comprising:

receiving a second control operation remotely initiated by user input to a user interface of a second motion capture camera of the plurality of motion capture cameras; and

adjusting a state of the second motion capture camera in accordance with the second control operation differently than the state of the first motion camera.

19. The method of claim 18, where adjusting the state of the first motion capture camera includes placing the first motion capture camera in a tracking view mode and adjusting the state of the second motion capture camera includes placing the second motion capture camera in a scene mode.

20. The method of claim 17, further comprising:

receiving a second control operation remotely initiated by user input to the user interface of the first motion capture camera of the plurality of motion capture cameras; and

displaying a view of the capture volume from the first motion capture camera.
