Scripts that we wrote to acquire the images.

The first way we thought about is to use the Matlab image acquisition tool box. (use imaqtool to call the toolbox)

It provides pretty good results for a single camera. But our demand is to get two images from the two cameras at the same time.
So I write a simple script to capture the images synchronously.
// Get the videoinput object:
cam1 = videoinput('dcam', 1, 'Y422_800x600');
cam2 = videoinput('dcam', 2, 'Y422_800x600');
// Change the camera property:
src = getselectedsource(cam1);
set(src, 'AutoExposure', 80);
// ... a lot of properties adjustments here...


// start capturing:
preview(cam1);

preview(cam2);
index = 1;
while 1
    key = input('x = exit acquisition, enter = acquire a pair of frame', 's');
    if key == 'x'
        break;
    else
       im1 = getsnapshot(cam1);
       im2 = getsnapshot(cam2);
       im1 = ycbcr2rgb(im1);
       im2 = ycbcr2rgb(im2);
       img_pair = {im1, im2};
       img_pairs{index} = img_pair;
       index = index + 1;
    end
end
stoppreview(cam1);
stoppreview(cam2);
closepreview(cam1);
closepreview(cam2);

this code get the keyboard as input, it gets every frame once I clicked enter end exits when I hit 'x'.
If I want get continues frames as videos, I can simply comment the "keyboard input" line and let it acquire images every frame.
