STH-DCSG-VARX

The STH-DCSG-VARX holds two global shutter cameras on a wide variable baseline rig for large-baseline applications for scenes with motion: Global shutter, low-noise, high-sensitivity CMOS imager. Color or monochrome.  Uncompressed video at VGA resolution (30 fps). Full synchronization of the cameras. Simple IEEE 1394 FireWire interface.  Variable baseline from 18 to 60 cm. Extremely rigid aluminum alloy bracket. Includes C/CS-mount lenses and SRI Small Vision System software for real-time stereo analysis. Offering high performance and low power with motion capture in a flexible package.

Features

  • Color and monochrome versions
  • Global shutter: all pixels exposed at the same time
  • Maximum resolution: 640H x 480V pixels
  • Variable baseline: 18 - 60 cm (7.1 - 23.6 in)
  • Dual-cable FireWire interface for power, data, and control
  • Accepts standard C/CS-mount lenses
  • Simultaneous exposure and readout
  • Direct digital information from the imagers, bypasses analog noise and frame grabber jitter
  • External synchronization: all STH-DCSG-VARX 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, milled aluminum bars for rigid camera mounting
  • Seamless interface to SVS™ stereo analysis software

Camera Kit

  • STH-DCSG-VARX stereo head, color or monochrome
  • 60 cm variable baseline rig
  • 4.5 mm C-mount locking lenses standard; other lenses available as options
  • Small Vision System stereo analysis software (one license for either MS Windows 2000 / XP / Vista* or Linux 2.4 / 2.6)
  • Two 2 meter IEEE 1394 6-pin to 6-pin cables
  • 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.
