That looks pretty cool, and it would be perfect for a standalone unit that handles the camera and video display, but I've actually got everything already set up with a standard PC. I suppose I could network the pi, but I fear that might add unnecessary latency/sync issues. A USB camera seems like it would be ideal, but I might still tinker with this.

Hey guys, I'm pondering a "laser shooting gallery" type project where I have a projector screen displaying moving targets, a "laser gun" that briefly emits laser beam when the trigger is pulled, and a camera that monitors the screen to determine where the laser hit.

I stumbled across OpenCV, and it sounded ideal for this type of thing. I just have a couple questions to start with:

1) Has somebody already done something like this (and can save me a bunch of work? :)

2) Any suggestions for cameras? I've noticed most webcams seem to have severe latency, but I'm not sure if that's the camera or software (hopefully OpenCV will reduce latency on the software side). I'm thinking that a higher framerate (60+ fps, ideally 100+) would be more important than high resolution.
