The
Firefly by Cybernet Systems Corporation / Cybernet Interactive
is a high-speed real-time optical tracking system designed for full
body motion capture. The system consists of a factory calibrated
camera array that tracks the position of active tags. The tags are
infrared light emitting diodes (LEDs) that are wired to a small
controller that can be worn by the user. The controller itself does
not need to be tethered to the camera array allowing the user to
feel unencubmered and free. Each tag controller is capable of hosting
up to 32 tags, and multiple controllers can be slaved to handle
up to 256 tags.
Synchronization between the tag controllers and camera arrays is
accomplished using proprietary optical syn-chronization techniques.
The Firefly system uses line scan camera technology to track the
tags accurately and quickly. With a scan rate of 900 tags per second,
a user tracked body with 30 tags can be tracked at a rate of 30
scans per second. When fewer tags are tracked, the scan rate can
be increased (e.g. 10 tags at a rate of 90 Hz.)
Since this motion capture system is optical, it retains its accuracy
when operating near metal objects and structures or noisy machinery.
The system was developed to operate in ordinary office, studio and
labora-tory settings without having to observe special lighting
precautions. The factory calibrated Firefly system is quick and
easy to set up, providing the accuracy of an optical system with
the real-time speed of other tracking technologies at a reasonable
cost. High speed data processing yields 3D motion data not only
in real time (no post processing required!) but with only a few
milliseconds delay.
This makes the Firefly system ideal for an in-house motion capture
capability for any game developer, animator, virtual reality environment
creator, or researcher.
