Re: Field lighting interference with camera tracking

I'm curious if any other teams are having this problem and how they are solving it. I'm on electrical on my team, so I don't know much about programming. I have heard that this has been mainly a programming issue, but I am curious if there are any types of LEDs that are effective, or any other tips with camera placement that could resolve this problem. Also, if anyone has programming tips, I can pass those on to our team's programmers.
Did you configure your camera using the tips in the vision white paper? Shining a bright light (we used an eWatt bulb at about 18") into your camera and then resetting the brightness makes the color of the ultra bright green LEDs that many people are using really pop. Without doing so, you get too much saturation.
