I just read the FRC PDF on the 2012 vision tracking system. It talks about different lighting techniques that I found useful, however I had a question that is open for talking through. Instead of using regular LED's around the camera for the retro reflective tape, why not use IR LED's? Digital cameras easily pick it up, however that does bring up the question of "making the camera blind" so it can only see IR waves. I think was wondering if this were possible since it would cut down on a ton of processing power for an image. What does every one else think?

PS: If you're wondering about edge detection in a language other than LV look up using a high-pass filter and a sobel gradient filter. These are used for the core of edge detection.
