STH-DCAM USER’S MANUAL
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.
