I have a friend who's using two of these Logitech[^] cameras on his robot. He has stereo image capture working with OpenCV running on a Beagle Board[^] under Linux. They're not the cheapest webcam but a lot cheaper than trying to buy a commercial stereo camera rig.

You didn't mention what OS you'll be using. The OpenCV frame caputure routines in the HighGUI library have some problems on Vista but are fine under XP. The simple streaming cam routines based on DirectShow work on Vista, however. I'm investigating a fix I found and am looking into other capture routines.

Yes, it is. I've been going for two years now. There's a quite diverse crowd and some of them are very active in robots and even a couple who manage to make a living at it. One of the members is a 17 year old kid who currently has an internship at Willow Garage.[^]

BTW, you do know about the OpenCV group on Yahoo?
