so what are those conditions? 
what are you trying to achieve, constraints, etc. 
I agree that infrared is the way to go so you don't interfere with projection lights, but haven't done this myself.

I'd get an infrared camera[1], make a simple threshold test, and get whatever is higher than the threshold to be white and the rest black and then go on from there...
