Vision Sensor To Line Up

Hey,

I was just wondering if many teams were using the V5 vision sensor to line up to the flags and shoot. If so, what ways do you guys use the vision sensor to line up especially when the flags are flipped partly. And what flags do you guys aim your vision sensor at? Thanks

We originally started the season doing this by looking for red or blue color codes near green and making it so the robot will turn until the geometric center of the flag is at the center of the camera view. Overtime, we found it to not be as usefully once we became more used to driving the robot.
