V120:Duo - Out of the box motion tracking

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.

V120:Duo - Plug-and-play motion tracking

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.

Motive:Tracker - Rigid Body Tracking Software

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 passive markers and active LEDs. 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
Segment
MJPEG-compressed grayscale
Raw grayscale

Camera control

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
Exposure
Threshold
Illumination
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 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.

OEM integration

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.

Feature Comparison

	V120:Duo/Trio	Full Multi-Camera Systems
Pre-calibrated for Plug and Play motion tracking OptiTrack’s tracking bars are pre-calibrated at the factory, prior to shipment—meaning that no user calibration is required. Full multi-camera systems built with multiple cameras require camera arrangement, cabling, and calibration by the user prior to tracking.	•
6DoF tracking with a single device A single tracking bar device can track rigid bodies in 6DoF out of the box, while OptiTrack motion capture cameras require multiple (3+) calibrated cameras to capture 6DoF object data.	•
Highly portable Each tracking bar is a self-contained system, offering engineering-grade 6DoF tracking in a highly portable form factor. While full motion capture systems can provide superior scalability and performance, they cannot be transported or deployed nearly as quickly as a tracking bar.	•
Includes free motion tracking software Each tracking bar is bundled with a free license of Motive:Tracker, OptiTrack’s engineering-grade rigid body and marker tracking application. Multi-camera systems require the additional purchase of Motive:Tracker, Motive:Body, or Expression software for motion capture capabilities.	•
Expandable camera counts and volume sizes Our multi-camera systems can be customized with additional cameras, while tracking bars must be used as stand-alone devices. Adding more cameras enables: 360° camera arrays for reduced occlusion and increased tracking accuracy Larger and more complex capture volumes More camera redundancy for improved coverage throughout volume Expandable systems for enhancing tracking capabilities over time		•
Multiple camera positions Cameras tracking from multiple locations improves redundancy, range of motion and coverage. Markers blocked from one camera's view can remain visible to cameras at other positions which allows tracking to continue seamlessly.		•
