One of the nice features of the Limelight that we would love to see for Photon is the ability to use a photo or video from the computer to set tuning constants on the Raspberry pi.
At events, we have never been able to take advantage of the limited time teams are given to calibrate vision on the field. This is mostly due to the fact that we are a small team, and those who are able to perform that task are busy getting the robot ready for competition in other ways.
So, the prospect of recording through either photon or even shuffleboard during our first match, and then calibrate using that footage could be incredibly helpful.
Now that I think of it, it could be helpful to do this even if we manage to get time to calibrate before the qualifiers begin.
