Actor-mounted motion capture camera
The present invention relates to computer capture of object motion. More specifically, embodiments of the present invention relate to capturing of facial movement or performance of an actor. Embodiments of the present invention provide a head-mounted camera system that allows the movements of an actor's face to be captured separately from, but simultaneously with, the movements of the actor's body. In many embodiments, multiple cameras are provided mounted on a bracket for placement on the head of an actor. In some embodiments, the cameras record grayscale images of an actor's face, which has been marked with dots of makeup. In many embodiments, the cameras record images of an actor's face from at least two angles.
1. An external three-dimensional camera system configured to capture images, comprising:
a first plurality of head-mounted cameras configured to capture images of at least a portion of a first side of an actor's face from at least two different angles, and
a second plurality of head-mounted cameras configured to capture images of at least a portion of a second side of the actor's face from at least two different angles.
2. The external three-dimensional camera system of claim 1 , wherein the first plurality of head-mounted cameras are configured to be fixed in a first position.
3. The external three-dimensional camera system of claim 1 , further comprising a processor configured to process image data from the first plurality of head-mounted cameras and the second plurality of head-mounted cameras.
4. The external three-dimensional camera system of claim 1 , wherein the images include marker data.
5. The external three-dimensional camera system of claim 1 , wherein the first plurality of head-mounted cameras and the second plurality of head-mounted cameras are micro-cameras.
6. The external three-dimensional camera system of claim 1 , wherein the first plurality of head-mounted cameras and the second plurality of head-mounted cameras are configured to record grayscale images.
7. A motion capture camera system comprising:
a first plurality of micro-cameras, configured to capture images of at least a portion of a first side of an actor's face from at least two different angles;
a second plurality of micro-cameras configured to capture images of at least a portion of a second side of an actor's face from at least two different angles;
a helmet that is adapted to be positioned on an actor's head;
a first mounting bracket connected to the helmet, wherein the first plurality of micro-cameras are positioned on the first mounting bracket;
a second mounting bracket connected to the helmet, wherein the second plurality of micro-cameras are positioned on the second mounting bracket;
a processor connected to said micro-cameras; and
a transmitter connected to said processor.
8. The motion capture camera system of claim 7 , wherein the first plurality of micro-cameras are configured to be fixed in position with respect to the first mounting bracket and the second plurality of micro-cameras are configured to be fixed in position with respect to the second mounting bracket.
9. The motion capture camera system of claim 7 , wherein the transmitter is a wireless transmitter.
10. The motion capture camera system of claim 7 , wherein the processor is configured to process image data from the first plurality of micro-cameras and the second plurality of micro-cameras to produce three-dimensional image data of the actor's face.
11. The motion capture camera system of claim 10 , wherein the image data includes marker data.
12. The motion capture camera system of claim 10 , further comprising a plurality of surface-mounted cameras, wherein said surface-mounted cameras are configured to capture image data of an actor's body from at least two different angles.
13. The motion capture camera system of claim 12 , wherein the plurality of surface-mounted cameras are connected to the processor.
14. The motion capture camera system of claim 13 , wherein the processor is configured to process image data from the plurality of surface-mounted cameras to produce three-dimensional image data of the actor's body.
15. A method of motion capture of an actor's face comprising:
positioning a head-mounted camera system on the actor's head, wherein the head-mounted camera system comprises a first plurality of head-mounted cameras and a second plurality of head-mounted cameras;
configuring the first plurality of head-mounted cameras to capture image data of at least a portion of a first side of the actor's face from at least two different angles;
configuring the second plurality of head-mounted cameras to capture image data of at least a portion of a second side of the actor's face from at least two different angles;
acquiring images of the actor's face, wherein the actor's face is marked with marker dots;
transmitting the images to a processor; and
processing the images to obtain three-dimensional image data of the actor's face.
16. The method of motion capture of an actor's face of claim 15 , wherein the captured image data includes marker data.
