The V120:Trio tracking system offers the power of multiple-camera, 6DoF object tracking in a single, plug-and-play package. Each tracking bar is self-contained and pre-calibrated prior to shipment—meaning that no user calibration is required—for out of the box motion tracking that is simple to use, but still offers the leading accuracy and flexibility of optical tracking technology.
Plug-and-play multi-camera motion tracking
Enjoy many of the same benefits as large scale, multi-camera tracking—such as enhanced accuracy, larger capture volumes, and tracking of multiple, customizable objects—distilled down to a single hardware unit and simple I/O.
Super portable, desktop friendly capture
At less than two feet in total length, the V120:Trio packs comprehensive tracking capabilities into a portable form factor—enabling easy transport and rapid deployment of the entire system.
Bundled engineering-grade software
Every purchase of Duo or Trio hardware includes a free license of Tracking Tools, OptiTrack's engineering-grade rigid body and marker tracking application. Features include:
6DoF object tracking
Quickly create custom rigid bodies to track position and orientation in all six degrees of freedom. Custom marker arrangements enable you to track a variety of object shapes with either passive or active markers. Additionally, high level tracking filters and constraints can be implemented to further tune when markers and rigid bodies are tracked.
Real-time data streaming
Built-in support for industry standard VRPN and trackd protocols makes integrating real time tracking data with your applications a snap. Stream to or from your application using the included network transport for convenient cross-platform communication. For a wider range of data streaming types, use OptiTrack's NatNet SDK.
Data recording, playback, and export
Tracking data can be recorded within Tracking Tools for playback or repeated reconstruction with new point cloud parameters. Export recorded data in both C3D and CSV formats for motion capture and analysis.
Proven camera architecture
The Trio is built on OptiTrack's custom image processing platform, which offers professional motion tracking capabilities at unparalleled pricing.
On-camera image processing
A variety of pre-processed image types are supported on-camera, resulting in decreased bandwidth and CPU load and more efficient motion tracking. Image processing types include:
- Precision Grayscale
- Segment
- Object
- MJPEG-compressed grayscale
- Raw grayscale
Camera control
Access a variety of camera settings with the Tracking Tools Application and API for greater control over what your cameras capture and report to the PC for processing. Available settings include:
- Image processing type
- Frame rate
- Exposure
- Threshold
- Illumination
- Filter switching
- And more...
Grayscale video with MPEG compression
When operating any of the Trio's cameras in grayscale, on-camera MJPEG compression is available for reduced USB bandwidth and CPU usage. MJPEG compression consumes 1/10th the bandwidth of uncompressed video while still enabling real-time grayscale video at full frame rate and full resolution.
Precise, efficient motion tracking
The Trio is capable of capturing fast moving objects with its global shutter imager and 120 FPS capture speed. Using advanced image processing to maximize resolution from its three 640 × 480 VGA sensors, the Trio can also track markers down to sub-millimeter movements with repeatable accuracy.
Enhanced scene video with FS technology
Each camera inside a Trio can operate in grayscale mode for high-speed, full-frame reference video. Additionally, the middle camera is equipped with Filter Switcher technology, for visible-spectrum imaging that offers enhanced image quality and more flexible illumination options.
External synchronization
External sync in/out is supported with the included I/O-X sync box, for seamless compatibility with shutter glasses and other hardware devices.
Compatible with Insight VCS virtual camera plugins
Create a complete desktop virtual camera system for just over $3k with a V120:Trio, VCS:Mini, and a VCS plugin to MotionBuilder or Maya. The Trio can be fully integrated into an Insight VCS pipeline, out of the box, via the bundled Tracking Tools software.
OEM integration
Incorporate the Trio into your own applications for seamless OEM integration via the Tracking Tools API, which is included free with every Trio purchase. This API provides software development access to the full tracking and streaming capabilities of the Trio.
