So i am working on my stereo vision using 2 live feed usb cameras.
As we know, disparity is the difference between corresponding points on a plane(we assume we rectified it perfectly) or denoted as d = x(left image) - x(right image).
BUT WHY DISPARITY in a LIVE VIDEO FEED FLUCTUATES OR CHANGES????? My object does not change position though. What the reason? Can u give me literature about it?
