Vision Problems Under Regional Lights[GRIP]

This is what we ended up doing... They kept changing the lighting on us. When they turned the spotlights on, it was too bright.

I mentioned this problem to someone with a differential signalling background and his first suggestion is one I hadn't thought of. He said, why don't you look at the target with the ring light on and then off, and then subtract out the noise?

I can't promise it would work, but it's an intriguing idea...

We also use GRIP to process the image produced by our Axis M1011 camera. In order to filter out the bright lights, we use a negative photographic film (covering the camera lense completely). Depending on how developed the film is, you may have to add multiple layers of negative film.

If you are looking for high goal calibration or auto, consider using infrared - it works really well with GRIP. (Initially I tried using a Microsoft Lifecam HD-3000 with IR, but it did not produce promising results on GRIP. After further research, I found out that the Webcam itself had an infrared filter, thus leading to our team using an Axis camera instead).
