Asynchronous streaming of data for validation

摘要

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 some embodiments of the present invention, a method of motion capture of an actor's performance is provided. A self-contained system is provided for recording the data, which is free of tethers or other hard-wiring, is remotely operated by a motion-capture team, without any intervention by the actor wearing the device. Embodiments of the present invention also provide a method of validating that usable data is being acquired and recorded by the remote system.

1. A method of motion capture animation of an actor's performance comprising:
facilitating capturing of body motion and facial motion of the actor at substantially the same time, wherein the facilitating includes:
placing a first number of body markers on the actor's body;placing a second number of makeup facial markers on the actor's face, wherein the second number of makeup facial markers captures facial motion of the actor's face with a higher resolution than the first number of body markers captures body motion of the actor's body;mounting a head-mounted motion capture camera system onto the actor's head;acquiring body image data corresponding to the body markers during the actor's performance with a first set of fixed motion capture cameras; andacquiring facial image data corresponding to the makeup facial markers during the actor's performance with the head-mounted motion capture camera system; processing the captured body motion and facial motion separately, wherein the processing includes:
storing the body image data on a server;storing the facial image data on a data logger, wherein the facial image data comprises camera images of the actor's face; and validating whether usable facial image data is acquired by the head-mounted motion capture camera system and is stored on the data logger, wherein the validation includes:
selecting camera images of the actor's face at intervals from the facial image data from the data logger, wherein the selected camera images are fewer in number than the stored camera images;transmitting a low resolution stream of the selected camera images to a wireless receiver, wherein the stream includes data associated with the state of the data logger; andvalidating whether the low resolution selected camera images are valid; and if the selected camera images are determined to be valid, transmit the facial image data stored on the data logger to a server.
