摘要： A method for tracking objects within a three-dimensional capture zone includes placing at least four sensors around the capture zone. A stationery reference tag is placed within the capture zone. Tags are coupled to objects to be tracked in the capture zone. Signals are periodically transmitted from the reference and object tags. These signals are received and the identification code, and code phase and carrier phase measurements are extracted. The code phrase and carrier phase measurements are processed to determine the position of each object tag with respect to the reference tag at each sampling instant.

摘要： A system and method for animating facial motion comprises an animation processor adapted to generate three-dimensional graphical images and having a user interface and a facial performance processing system operative with the animation processor to generate a three-dimensional digital model of an actor's face and overlay a virtual muscle structure onto the digital model. The virtual muscle structure includes plural muscle vectors that each respectively define a plurality of vertices along a surface of the digital model in a direction corresponding to actual facial muscles. The facial performance processing system is responsive to an input reflecting selective actuation of at least one of the plural muscle vectors to thereby reposition corresponding ones of the plurality of vertices and re-generate the digital model in a manner that simulates facial motion. The muscle vectors further include an origin point defining a rigid connection of the muscle vector with an underlying structure corresponding to actual cranial tissue, an insertion point defining a connection of the muscle vector with an overlying surface corresponding to actual skin, and interconnection points with other ones of the plural muscle vectors.

摘要： Small radio frequency tags for use in a motion capture system include a power source, circuitry for generating radio frequency identification signals, an antenna for transmitting the signals, and means for automatically activating the tags so that the tags begin transmitting the signals including a tag identification code when a cover is removed. The activation means may include a release strip that, when removed, opens or closes an electrical circuit that activates the tag and also exposes an adhesive covered surface of the tag so that the tag can then be adhered to a clothed or unclothed human body or other object to be tracked. The activation means can also include an optical sensor, an oxygen sensor, or other sensors. The battery and the antenna may be printed or constructed of film, thus allowing the tag to be small, thin, and flexible.

摘要： A radio frequency (RF) motion capture system includes stationary sensor receivers, one or more transmitter marker tags on one or more objects to be tracked within a capture zone, at least one stationary reference tag transmitter, and a processing system for processing the received signals. The individual tags transmit burst of spread-spectrum RF signals. The transmitted signals include a common sync code, and a tag identification code that is unique to each tag. By computing double differences of pseudoranges, clock terms are cancelled out allowing the processing system to precisely determine the location of each tag as it moves through the capture zone without the need to synchronize clocks between sensors and tags. The system can be used for RF match moving.
