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.
On-Camera
Image Processing
The Flex 3 can send a variety of pre-processed image types to the PC, resulting in more efficient imaging and system scaling. Image processing types include:
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.
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.
Raw Grayscale
Full resolution, uncompressed grayscale.
MJPEG compression
Unique to OptiTrack cameras, on-camera MJPEG compression consumes 1/10th the bandwidth of uncompressed video while still enabling real-time grayscale video at full resolution and full frame rate.
Compact, high-quality grayscale video enables image preview with multiple cameras, simultaneously—an indispensable tool for camera aiming and focusing during rig setup and 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
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.
100FPS
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.
