STH-DCAM USER’S MANUAL 2001 VIDERE DESIGN
1 Introduction
The STH-DCAM (Dual-DCAM) is a compact, low-power digital stereo
head with an IEEE 1394 digital interface. It consists of two VGA
(640x480), progressive scan CCD imagers and associated IEEE 1394
electronics, mounted in a rigid, milled Delrin frame.
The CCD imagers are Sony HAD ¼” devices, with square pixels and
progressive scan output. They have 648 H by 484 V pixels, and are
colorized using a standard Bayer pattern. These imagers have excellent
dynamic range, sensitivity, anti-blooming, and noise characteristics. They
are fully controllable via the IEEE 1394 interface, in both manual and
automatic modes. The user can set exposure, gain, binning, etc., or have
the stereo head electronics do it automatically.
The STH-DCAM uses standard 12 x 0.5 mm miniature lenses for user-
changeable optics. Wide-angle to telephoto options are available,
depending on the application.
There are software drivers for the STH-DCAM for MS Windows
98/2000/XP, and for Linux 2.4.x kernels.
SRI’s Small Vision System (SVS) software has an interface to the STH-
DCAM. You can simply and automatically calibrate the stereo head,
perform stereo correlation, and view the results as a 3D set. The SVS
software includes all of the capture software described in this document.
