Here is the setup I threw together with 850nm leds I already had and how it works.

Here you see the IR first test on a ceiling QR code at 7ft 4 inches away and the code way crooked , wrinkled and my dog tore a edge off and it consistently read it. The IR light us invisible to the naked eye and mostly invisible to modern cameras due to IR filters. After popping my EZ cam filter out the QR code is now read even better than when I illuminated it with a 1 watt led. It was even able to read the smaller Qr code at that distance so I see that IR illumination is much more effective than white light. I was pretty "geeked out" when I saw it literally worked better that using visible lighting. The camera also did not need to constantly adjust to the white balance like when I was using the super bright white led. Now I just need to figure out how to read the orientation of the QR code when read and that will always tell the robot which direction it is facing.
