A board level camera designed for integration in computer vision, multi-touch, and custom tracking applications.
Reality Touch Theatre
Slim 3U cameras are placed behind the screen so that when someone touches the screen, infrared light is reflected back to see the tip of the finger.
On-Camera Image Processing
On-Camera Image Processing
The Slim 3U can send a variety of pre-processed image types to the PC, resulting in more efficient imaging and system scaling. Image processing types include:


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.

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.

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.

Components a la carte. Build your Slim 3U 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:
- Aluminum case - with CS lens mount and 1/4"-20 tripod thread
- Filter options - 800nm pass filter, Filter Switcher, empty filter plug
- Lens mount adapter - CS to M12, CS to C—only available with SLIM case
- M12 lens - 3.5mm, 4.5mm, 5.5mm
- Input/output - Sync break-out cable, Micro 9-pin connector

Fast, precise, and efficient capture. 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.
OEM & computer vision Integration. Incorporate Slim 3U cameras into OEM tracking or computer vision applications via the free , 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.
