STH-MD1 USER’S MANUAL ?2001 VIDERE DESIGN

1 Introduction
The STH-MD1 is a compact, low-power digital stereo head with an IEEE
1394 digital interface. It consists of two 1.3 megapixel, progressive scan
CMOS imagers mounted in a rigid body, and a 1394 peripheral interface
module, joined in an integral unit.
The CMOS imagers are from PixelCam (now a part of Zoran Corporation).
They have 1288 H by 1032 V pixels, and come in either monochrome
(STH-MD1) or colorized (STH-MD1-C) versions. These imagers have
excellent dynamic range, sensitivity, anti-blooming, and noise
characteristics. They are fully controllable via the 1394 interface: the user
can set exposure, gain, subwindow, decimation, etc. They can be used
interchangeably with the same interface module.
The STH-MD1/-C uses standard C-mount lenses for user-changeable
optics. Wide-angle to telephoto options are available, depending on the
application.
The wide baseline version of the STH-MD1/-C has exactly the same
characteristics as the STH-MD1/-C, with the exception of range resolution
and mounting diagrams.
There are software drivers for the STH-MD1/-C 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-
MD1/-C. 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.
