STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 3 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.
STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 4 2 Quick Start The STH - MD1/ - C comes assembled, the interface module mounted to the imager module. The module comes without mounted lenses. To set up and test the STH - MD1/ - C, you will need the following: 1.

STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 8 4 Lenses The STH - MD1/ - C uses standard C - mount lenses. Good - quality, fixed - focus lenses with low distortion and high light - gathering capability are best. Lenses are characterized optically by imager size, F number, and focal length.
STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 9 chooses the focal length based on the narrowest field of view acceptable for an application, and then takes whatever range resolution comes with it. 4.6 Range Resolution Range resolution is the minimum distance the st ereo system can distinguish.
STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 10 5 1394 Interface Digit al image information is transferred from the STH - MD1/ - C to the host PC via a 1394 cable. The cable sends a video stream from the imagers to the PC, and sends commands from the PC to the stereo head to control exposure, subsampling, etc.
STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 11 6 User Controls The CMOS imagers are fully controllable via the 1394 interface. User programs may input color images (STH - MD1 - C only), set video digitizat ion parameters (exposure, gain, red and blue balance), subsampling modes, and region - of - interest (subwindowing).

You can add gamma correction to the displayed image by choosing an appropriate gamma value in the slider under the right display window ( Figure 6 - 2 ).
STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 13 Figure 6 - 2 shows the frame size and subsampli ng controls on the video capture application. Any x2 or x4 subsampling is allowed, including combined binning and decimation. 6.5 Subwindowing Often the area of interest in an image will be a small portion of the whole image.
STH - MD1 U SER ’ S M ANUAL ? 2001 V IDERE D ESIGN 14 The ve rgence control is on the Video Parameters dialog ( Figure 6 - 1 ). 6.8 Frame Rates Frame rates from the STH - MD1/ - C depend on two factors: decimation and the number of image lines in a subwindow.
