hello!
I'm studying in stereo vision using 2 webcams.
Now, I have some questions.
I want real depth(from webcams to object). So, I calibrated my webcams, then, I got disparity maps.
I use a formula that is depth = baseline * focal length / disparity
However, I got wrong depths.
So, here are some questions.
First, I think depth(cm) = baseline(cm)*focal length(pixel) / disparity(pixel) is right. I'm not quite sure that measure of disparity is pixel. I calibrate my webcams using by 1-inch chessboard(point to point = 1-inch). Then, the result of disparity is pixel or inch??
Next, I set a min disparity(4). It means that originally min disparity was increased. right? I think it can be affected to real depth. If so I would do not touch min disparity ...?
