The V120:Duo 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 one foot in total length, the V120:Duo 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 Motive:Tracker, 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 Motive:Tracker for playback and post-processing. Export recorded data in both C3D and CSV formats for motion capture and analysis.
Proven camera architecture
The Duo 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
- MJPEG-compressed grayscale
- Raw grayscale
Access a variety of camera settings with the Motive:Tracker 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
- Filter switching
- And more...
Precise, efficient motion tracking
The Duo 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 two 640 × 480 VGA sensors, the Duo can also track markers down to sub-millimeter movements with repeatable accuracy.
External sync in/out is supported with the included I/O-X sync box, for seamless compatibility with shutter glasses and other hardware devices.
Incorporate the Duo into your own applications for seamless OEM integration via the Motive:Tracker API, which is included free with every Duo purchase. This API provides software development access to the full tracking and streaming capabilities of the Duo.
