The STOC performs stereo processing on the camera instead of on the PC, faster, with lower power (just 2 watts), and in a compact package.
Pre-calibrated so it is plug-and-play. Global shutter to capture scenes with motion. For applications with limited computational resources.
Standard FireWire interface delivers video and disparity (range) information over a single cable.
6, 9, 15, and 30 cm baselines. Offload the stereo computation from your PC, freeing up resources for your own application.

Features

Color and monochrome versions
Global shutter: all pixels exposed at the same time
Maximum resolution: 640H x 480V pixels
Baseline options: 6, 9, 15, and 30 cm
Single-cable FireWire interface for power, data, and control
Uses miniature 12 mm diameter lenses
Stereo computation on the chip reduces PC computation
Factory calibrated and field upgradeable using standard SVS™ calibration procedure
Simultaneous exposure and readout
Direct digital information from the imagers, bypasses analog noise and frame grabber jitter
Synced imagers expose corresponding pixels at exactly the same time
External synchronization: all STOC devices on the same IEEE 1394 bus are synchronized to capture images simultaneously
Subsampling modes (binning and subwindow) for smaller frame sizes, faster frame rates, lower noise
Electronic gain and exposure
Fully under user control via the IEEE 1394 bus
Conforms to Digital Camera Specification version 1.30
Milled solid aluminum alloy body for extreme rigidity
Seamless interface to SVS™ stereo analysis software

Camera Kit

STOC stereo head, color or monochrome
3.0 mm miniature 12 mm diameter lenses standard; optional C/CS-mount lenses for 9cm baseline
Small Vision System stereo analysis software (one license for either MS Windows 2000 / XP / Vista* or Linux 2.4 / 2.6)
2 meter IEEE 1394 6-pin to 6-pin cable
Tripod for 6 cm and 9 cm models
Hardware and Software Manuals (download)

Requirements

Pentium-compatible PC (Pentium PIII/clone or better) running MS Windows 2000 / XP / Vista* or Linux 2.4 / 2.6 kernel
IEEE 1394 PCI or PCMCIA card. IEEE 1394 card must supply 1.5W of power through the 6-pin cable. Most PCI cards do this; PCMCIA cards must have a separate transformer power input. Interface cards are available from Videre Design, see Accessories

* Vista compatible for all cameras sold after 12/01/08.
