Re: Turrets and cameras

At the DC Regional, there was an opportunity during lunch break on Thursday to calibrate cameras on the field. Greg McKaskle from NI (many of you might recognize his name from Chief Delphi) was there to help, but I only saw two teams (including us) actually out on the field. The first thing Greg said to do was to log in to the camera (192.168.0.90) and lower the brightness level to 0. After that, we tweaked our HSL values a little bit, showed them to Greg, and he approved.

During the matches, our camera seemed to work fine. The only problem was that we had written our code to rely almost completely on the camera, and we only tested our code on stationary targets. When our robot and the target robots were moving, our shooter would miss the target. The camera by itself, though, worked better for us than most people here seem to describe.
