Summary

Some webcam controls in the SDK could potentially improve TFOD recognitions. Exposure, gain and other values could be pre-programmed in team autonomous OpModes. It’s also possible to manually enter such values before a match begins, based on anticipated lighting, starting position and other game-time factors.

You are encouraged to submit other webcam reports and examples that worked for you.
