Stereo vision? Distortions? This one seem somewhat difficult to integrate.

I've been pondering, why would stereo vision be difficult? Is it due to the improbability of connecting two cameras to the D-Link or is it due to the difficulty in simply using the two cameras?
Stereo vision has a couple of steps. First is positioning the 2 cameras just right and get a very accurate measurement of the distance between the 2. Secondly, numerous algorithms that's entirely non-trivial will be needed to locate "things" in the 2 images and compare their location in the 2 images to get the distance of those objects

Even though it doesn't sound difficult, it is very tough to do in practise.
