Re: Two Color Tracking Demo

If the red and green masks look good, and your holding the target in the correct orientation, the next things I'd do is to watch the Tracking State indicator. When the camera doesn't see the target, it should search. When it acquires some pink and green that make up a foe, it uses the proportional constants to move the camera so that the target is closer to center. You may want to check the sign of the constants to see if the servos are moving in the wrong direction.

If you don't stumble on the issue soon, one thing that will help with debugging will be to put the target in frame, but off center. Position the servos with the FP knob and slider if you need to. Then put a break point after the FindTwoColor and follow it into the Servo Track VI to determine which of these is the issue.
