Vision systems always have issues with lighting. My co-workers still struggle with things like:
* Power fluctuations causing light intensity modulation.
* Skylights in factories that let in light at the wrong angle for 1 hour a day.
* Random people using flashlights/lasers/camera flashes at the wrong time.

You will have to have controls right on your dashboard to manipulate various settings. It shouldn't be difficult, but it will take some time. If you can get some practice rounds in, before/during the competitions on the actual field, this is ideal. You will also require a method of switching between settings. (Eg. An enum: [arena|practice|shop|other random place|...]) The more practice you have setting up the controls for your vision system, the faster you will be able to get it right. With enough practice, you may even come up with a algorithm that does the same thing in varying light conditions.
Good luck! I look forward to any examples that you guys post.
