STH-DCSG

The STH-DCSG is a revolutionary stereo camera with a global shutter specially designed for machine vision tasks of scenes with motion: Pre-calibrated, so it's plug-and-play. Global shutter, low-noise, high-sensitivity CMOS imager. Color or monochrome. Uncompressed video at VGA resolution (30 fps). Simple IEEE 1394 FireWire interface. 6, 9, 15, and 30 cm baseline options. Includes miniature lenses and SRI Small Vision System software for real-time stereo analysis. Offering high performance and low power with motion capture in a compact package.

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
All cameras with miniature lenses are pre-calibrated
Single-cable FireWire interface for power, data, and control
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 STH-DCSG devices on the same IEEE 1394 bus are synchronized to capture images at the same time
Subsampling modes (binning and subwindow) for smaller frame sizes, faster frame rates, lower noise
Electronic gain and exposure
All modes 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

STH-DCSG stereo head, color or monochrome
3.0 mm miniature 12 mm diameter lenses standard; other lenses available as options
Small Vision System stereo analysis software (one licese for either MS Windows 2000 / XP / Vista* or Linux 2.4 / 2.6)
Tripod for 6 cm, 9 cm, and 15 cm models

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.
