OptiTrack Prime 41 Volume

Incredible Range. 100’ passive camera-to-marker range and over 150’ with Signature Pulse Active3, all with discrete infrared wavelengths. This provides up to 290,000 cu ft/camera for tracking passive markers and over 1,000,000 cu ft/camera for tracking of active markers.

OptiTrack Primex equals precision.
Shot with Primex 41

Primex equals precision. In-house designed low distortion lenses and true 10-bit grayscale depth reduces quantization noise and improves precision—resulting in perfectly crisp and beautiful images, better centroids and better 3D accuracy.

Megapixels matter, but image quality matters more.

Intuitive & elegant design. In designing the Primex series, we considered the complete lifetime of a motion capture camera—from unboxing to setup, capture, and teardown. Each process is elegantly accommodated with a nod to simplicity and usability.

Tracks Passive and Active Markers with positional errors less than +/-0.10mm and rotational errors less than 0.5 degrees. For some tracking applications, customers find benefit in using a combination of active and passive markers.

Mix and match cameras. Any camera in the Prime and Primex family can be used together to create the optimal configuration for any use case. That is 11 different cameras that can be chosen to deliver the highest 3D accuracy in any environment.

“Fast glass” 12mm lens. We custom design our own super low distortion, “fast glass” lenses for optimal marker tracking. The Primex 41’s standard 12mm lens is treated with a wide band anti-reflective coating, which dramatically increases light transmission to the imager, yielding larger volumes and more precise 3D data.

Powerful on-board image processing. All OptiTrack cameras feature integrated image processing. The algorithms which identify markers and marker centers, and the sequence of data delivery are important steps to achieve both world leading accuracy and low latency.

On-camera status indicator. Your OptiTrack system will let you know what it’s up to with the user definable color LED indicator surrounding the lens. Recording a performance? Everyone on set knows the system is recording. Select a camera? It instantly changes color. Have your own idea? Simple software controls help you make it so.

New, higher output strobe. Ultra high power LEDs provide improved range for any given shutter setting. The world’s longest range motion capture camera just got even better.

Full resolution grayscale reference video. All Primex cameras can be used as a reference video source – with synchronized, calibrated 3D overlay. Deliver and/or record full resolution, full frame rate video with 3D overlay of markers, rigid bodies, skeletons, etc.

Outdoor capture out-of-the-box. Primex 41 extends its world record setting range to marker, for outdoor capture as well. For passive markers, the outdoor (bright sunlight, midday) range is about 50’ (16m). For Signature Pulse Active technology the range is > 70’ (21m).

Easy set-up. Aim assist and easily accessed lens controls make the Primex 41 fast and easy to set up.

External sync in/out, Genlock, and Time Code. Synchronize any Prime and Primex cameras to any signal or source with the eSync 2 with all the functionality and flexibility you’d expect with a professional tracking system. Cameras sync to dozens of sources including a professional cameras’ Genlock signal, where record and other event triggering can be managed from general purpose inputs and software commands.

Use the sync output signal as a master or to trigger force plates, EMGs and National Instrument DAQs for flexible yet precise hardware synchronization. Highly accurate frame timing can also be achieved with SMTPE Time Code for ease in editing and logging. OptiTrack’s free and open SDK allows for further customization within the timing protocols.

Expert system configuration for any space. OptiTrack has built over 10,000 tracking systems in areas of all shapes and sizes. Our experts can help guide you on the most economical and suitable tracking system for your needs—for today and the future.

Before Continuous Calibration
After Continuous Calibration

It’s more than just cameras. In addition to the essentials to which you’ve grown accustomed, you’ll also discover several new software features that will make you wonder how you ever got along without them. Enjoy innovations like our Continuous Calibration, where a wand wave is required on first installation only, then calibrates automatically just by using the system. No longer does the calibration degrade over time, temperature change, or after cameras are bumped

OEM & computer vision integration. Incorporate Primex 41 cameras into OEM tracking or computer vision applications via the free SDK, a C/C++ interface for control of and access to raw camera frames, image processing modes, camera settings, 2D object data, camera synchronization and all 3D data.

1. 3D accuracy referenced is typical for a 30’×30′ (9m×9m) tracking area. Passive range is estimated using a 14mm marker.
Frame rateResolutionFOV (standard 12.5mm lens)
180 fps2048×204851°×51°
250 fps2048×144051°×35°
3. Signature Pulse Active markers provide their own unique ID, resulting in 100% error free labels. When introduced into the tracking area, the LED markers are acquired in < 0.1 seconds. Unique marker placements based on spatial separation, normally required for passive marker tracking, are not required for distinguishing multiple rigid bodies.
