STH-MDCS USER’S MANUAL 2001 VIDERE DESIGN

1 Introduction
The STH-MDCS 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 ½” format, with a resolution of 1280 H by 1024 V
pixels, and come in either monochrome (STH-MDCS) or colorized (STH-
MDCS-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,
decimation, etc. They can be used interchangeably with the same interface
module.
The STH-MDCS/-C uses standard C-mount lenses for user-changeable
optics. Wide-angle to telephoto options are available, depending on the
application.
The variable baseline version of the STH-MDCS/-C uses the same imagers,
but has a separate IEEE 1394 interface for each imager. It has similar
characteristics to the STH-MDCS/-C; please see the STH-MDCS-VAR/-C
manual for more information.
There are software drivers for the STH-MDCS/-C for MS Windows
98SE/ME/2000/XP, and for Linux 2.4.x kernels.
SRI’s Small Vision System (SVS) software has an interface to the STH-
MDCS/-C, and is included with each stereo head. 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.
