Dealing with bright lighting at competitions and vision

[mabster314]

We use a green ring light and a single HSV filter, then use GRIP to find contours, filter out ones that are too small, and publish a report to a NetworkTable. The system has worked really well everywhere but Iowa, where the light was just too bright for our camera.

At Iowa, we were having similar problems. There were very large windows on either side of the field, and pointing a camera at the goals from our low bot was impossible without getting them into frame. Even with minimum exposure settings on the Axis camera, the windows were always the light it set the exposure based off of. We share a shop with 3130, who use the LifeCam, and they were having similar problems.

At North Star, we had no problems, and neither did 3130. We both used green ring lights, and they were bright enough to get a very good picture back from the camera. If you want, I can get you in touch with a member from 3130, as I'm not sure what they did with the LifeCam to set it up.
