Camera Tracking help please

[2472Programer]

This year, my team has for the first time decided to actually use the camera instead of it just being a place holder on the robot. The only problem with this is that I don't know how to program the camera to track the reflective targets on the field. I, so far, have gotten as far as getting the camera to take a picture and filter it down to the green box it is going to track. Now I need to get the robot it react and change its position accordingly. Any help is appreciated. A copy of my code is attached if anyone wants to check if i already messed something up.
