OptiTrack for Movement Sciences

OptiTrack systems offer the world’s leading blend of measurement accuracy and simple, easy-to-use workflows which provide researchers and biomechanists with ideal 3D tracking data for their studies.

Native, plug-and-play support for all major digital force plates, EMGs, and analog devices gives researchers the tools they need most for display and analysis in Visual3D, The MotionMonitor, MATLAB, and other third party biomechanics packages.

Precision Graph

The most accurate measurement system in the world.

OptiTrack systems typically produce less than 0.2 mm of measurement error, even across large tracking areas—even of those 10,000 sq ft or more. In smaller measurement areas, OptiTrack systems regularly produce errors of 0.1 mm or less.

Each part of every OptiTrack system has been designed with measurement accuracy as the principal goal. And now, with OptiTrack’s self calibrating systems, these levels of accuracy are maintained throughout the day, every day, just through the use of the system.

Higher density markersets, even in large volumes.

OptiTrack’s world leading range to marker, which is typically 2× of other optical motion capture systems, means that higher density marker sets can be measured alongside traditional full-body tracking. In fact, OptiTrack delivered the world’s largest, high marker density measurement system where over 100 markers—3 mm in size—are tracked in less than a cubic foot over a tracking area of 1000 sq ft.

Outdoor capture, out of the box.

Featuring ultra-powerful strobes and custom-engineered band-pass filters, Prime Series cameras track reflective markers outside—in full sunlight—with no need for special add-ons or hardware modifications.

Maximize tracking areas.

Our specially-designed wide FOV, low distortion lenses provide for tracking areas as big as the setup area. There are no design compromises that are common with other systems, where the range falls off as the marker moves away from sensor center.

OptiTrack delivers true edge-to-edge coverage that is ideal for tracking every inch of compact areas like gait labs.

Force Plate Support

OptiTrack offers native plug-and-play support for all leading force plate manufacturers. When used with OptiTrack cameras and an eSync 2, Motive’s plug-and-play force plate support integrates all force plates and precisely synchronizes them with the kinematic data, as well as offering real-time streaming, capture, and export of all ground reaction force components. Using OptiTrack’s CS-400 calibration square users can now position force plates into the tracking volume through the one-click positioning feature. Best of all, this means no need to enter the calibration matrices or multiple analog cables.

National Instruments DAQ Device

DAQ support for EMGs and other analog devices.

Motive’s native support for National Instruments USB DAQ devices enables motion capture data and analog data to be synchronized within +/-5 µs per camera exposure, with support for input frequencies up to 50 kHz via the eSync 2. This allows for acquisition from any general analog device, including triggers, EMGs, force places, accelerometers, and force transducers.

Validated Biomechanics Markersets

Motive supports numerous biomechanics marker sets, with a focus on scientific and anatomically-valid options. Whether your analysis takes place in Visual3D, The MotionMonitor, MATLAB, or another third-party tool, these markersets provide robust marker tracking with real-time labeling.

Prefer a more detailed markerset for multi-segment studies? Motive’s standard markersets can be augmented with additional markers for capturing more verbose datasets.

Extensive native support for Visual3D & The MotionMonitor.

Motive focuses on what OptiTrack does best—providing a simple path to capturing the highest quality 3D data in the industry. For the most advanced biomechanics analysis and reporting on the market, we recommend Visual3D or The MotionMonitor—now with enhanced support from Motive.

V3D and TMM-Friendly Markersets

Motive’s biomechanics markersets use naming conventions that are compatible with pre-built V3D and TMM models, providing a simple pathway between labeling and analysis.

Enhanced C3D Export

Combine tracking data, subject variables, device specs, force vector data, and analog device data into a single file—all following C3D formatting standards.

Real-Time Streaming

Stream live, labeled marker reconstruction data to native TMM, or to V3D via plugin to the Visual3D Real-time Server—ideal for real-time analysis, biofeedback, and verification.

The industry's most open optical tracking architecture.

Our free developer tools provide access to camera images, centroids, reconstructed 3D points, skeletal data, and nearly everything in between. This means that OptiTrack can fit into a range of existing workflows, without modifying your existing tools. Visit our Developer Hub to find the right SDK for your application.

Easy to Use

The day-to-day use of OptiTrack systems reduces or eliminates redundant efforts to which lab engineers and operators are often accustomed. No more daily wand wave, and no more placement of the L-frame at force plate corners. In fact, individual force plate location was more accurately defined on installation using actual measurement rather than dimensional offsets.

Each camera can be used as reference video, synchronised and calibrated for overlay. This is a software selection, allowing users to change the reference view with each trial if desired.

NatNet SDK

Deep Toolsets for the Expert User

For the expert user with highly specialized technical requirements, OptiTrack’s open SDK enables development of customized workflows, system operation and data analysis. OptiTrack even offers a headless version with which other software can manage and operate the tracking system via your own wrapper. Well documented workflows and sample codes make custom integrations fast and easy.

Data Management Tools

Easily manage complex capture sessions by creating a list of trials in a spreadsheet and dragging them into Motive, or building the list directly in Motive’s project interface. Once a trial list has been created, Motive will automatically progress through it from one recording to the next, with options for revising lists and trials on the fly.

Batch processing

Large batches of trials can be processed and exported quickly and automatically via customizable scripts, using the Motive Batch Processor.
