The Slim 3U is a board level camera designed for OEM integration in computer vision, multi-touch screens/surfaces, and custom tracking applications. It is fully customizable, with a variety of optional components and features. Software support includes the free Camera SDK, which provides complete control and access to camera settings.
Six Slim 3U cameras were used in making the Reality Touch Theatre at the University of Groningen.
The Slim 3U is capable of capturing fast moving objects with its global shutter imager and 120 FPS capture speed. By maximizing its 640 × 480 VGA resolution through advanced image processing algorithms, the Slim 3U can also track objects down to sub-millimeter movements with repeatable accuracy.
Build your SLIM piece by piece, optimizing it as you see fit. Custom building your camera gives you the flexibility to create a hardware solution that is tailored for your own application, satisfies your unique spec, and maximizes cost-efficiency. Optional components include:
With OptiTrack’s Camera SDK you can access a variety of Slim 3U settings for greater control over what your cameras capture and what information they report to the software application. Available settings include:
Precision Grayscale | Segment | Object
Precision Grayscale (orange) vs. Segment (green)
In addition to providing raw and MJPEG grayscale video, SLIM cameras can process and threshold data on-board, creating a variety of video modes deliverable to your PC, including:
Transmit MJPEG-compressed grayscale video at full frame rate and full resolution with 1/10th of the USB bandwidth of uncompressed video. MJPEG compression enables multiple cameras to stream video to the same PC, offering scalability superior to raw grayscale video.
Improve power regulation, camera syncing, tracking distance, and more.
Up to 24 SLIM cameras per PC can synchronize their shutters to expose at exactly the same time. Each synced camera can operate in different video modes with individually customized camera settings. Utilize OptiHubs in your sync chain to enable external syncing capabilities.
Upgrade any Slim 3U camera with the same Filter Switcher technology found in Flex 3 cameras, enabling visible spectrum video in addition to standard IR imaging. FS-enabled cameras are equipped with a solenoid that can be controlled in-software to extend or retract the infrared lens filter. OptiTrack's user-changeable, polychromatic M12 lenses are specially designed to remain in focus in both the visible and infrared spectrums.
Incorporate Slim 3U cameras into OEM tracking or computer vision applications via the free Camera SDK.
