Flex 3
Flex 3
A small volume motion capture camera that’s surprisingly affordable.
Compact design for low profile integration.
Flex 3 cameras can be discreetly integrated into small installations, or allow you to optimize desktop capture volumes for tracking different types of objects.
Start Small and Grow Over Time
OptiTrack systems are modular, reducing your initial investment in motion tracking technology. Start with a 6 camera bundle for under $7k, and as your tracking needs or budget expands, add more cameras or new software applications to increase the capabilities of your system.
Processing Types
Precision
Similar to Object processing, but sends selective grayscale images of markers to the PC for calculation of object data. Provides the most verbose marker information, but requires more CPU resources than Object processing.
MJPEG-Compressed Grayscale
Full resolution grayscale frames, compressed on-camera for highly scalable scene video capabilities.
Object
Performs on-camera detection of marker location, size, and roundness using our most precise grayscale processing methods. Provides excellent precision with the smallest CPU footprint.
Raw Grayscale
Full resolution, uncompressed grayscale.
Full Resolution Grayscale Reference Video
All Flex 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.
Zero Drift. Pure Precision.
Motive calibrates automatically and continuously with data collected during normal use of the system. No longer does your calibration degrade over time with changing temperatures or challenging building movement—it is always a “fresh” calibration.
Fast, precise, and efficient capture
The Flex 3 is capable of capturing fast moving objects with its global shutter imager and 100 FPS capture speed. By maximizing its 640 × 480 VGA resolution through advanced image processing algorithms, the Flex 3 can track markers with repeatable accuracy.
100 FPS
Interchangeable M12 lenses
The Flex 3 can be optimized for a variety of applications with custom-designed, interchangeable M12 lenses. Choose between 3.5mm and 4.5mm EFL lenses to adapt your cameras to your ideal capture volume. Both feature a special spring focus assist, very low distortion, and fast F#1.6 apertures for increased tracking distance. Typical applications utilize 3.5mm for capture volumes in smaller spaces, 4.5mm for larger capture volumes and camera counts.
Unobtrusive infrared light
Flex 13 cameras emit 850nm IR light, which is nearly invisible, for inconspicuous illumination that prevents the vision fatigue and unwanted attention to your capture rig caused by cameras that emit visible spectrum light.
Motive is behind every seamless workflow
OptiTrack’s Motive software delivers speed, precision, and ease of use, streamlining everything from calibration to real-time streaming, while tools like Aim Assist and auto-masking make even large system setups simple for one person.
- 3D accuracy referenced is typical for a 30’×30′ (9m×9m) tracking area. Range is estimated using a 14 mm marker with cameras at an exposure of 800, gain of 6, and the lowest f-stop. ↩︎
