This is the main concern. Those lights can be extremely bright, especially when there is more than 1 ring.

From what i can recall alliance members cant call fouls so whats the deal when ir happens my plan was post match notifying a ref to keep eyes on a tam. Our team wants to run leds on our robot for non decorative purposes but im concerned it might mess with other teams. Does anybody have experience with that.

Re: Vision Processing - How Bright is Too Bright?

The way my team has our camera mounted, a ring led won't fit around it so we cut strips of LEDs about 5 inches long, and stacked 3 of them over each other to put on each side. We haven't tried it out with vision tracking yet but when you put the LEDs next to each other and look inbetween (like if the camera was there) it completely lights up the tape on the tower and makes it look completely green. We may have to dial it down a little bit.

Re: Vision Processing - How Bright is Too Bright?

Since our initial testing at Zebravision Labs showed that the tape on the goals is not in fact retro-reflective to a pumped x-ray laser source* (talk about false advertising), we decided to go with the approach of one of the smaller rings per camera. Still seems a bit bright at close range but it is workable for now for our planned shooting distances.

The trouble with trying to fine tune this so it is just bright but not too bright is a lack of access to to an actual field with realistic lighting conditions. You can (relatively) easily build a goal, but guessing how much interference you'll have from other lights is tough. Better to be safe and a little overpowered than right on the edge and have it fail in a match if your guess is wrong. Hopefully the refs will be a bit lenient and understand that challenge. Plus think of all the money they're saving on spray tans.
