help with labview camera target tracking with turret needed

[badger3.14]

We are using a webcam to track the rectangles around the hoops, and our program can pick up the rectangles but we cannot figure out how to lock on to the rectangles and have the program automatically stay aimed at the rectangle. We are using a PID but are having a hard time trying to figure it out.

I know other teams are doing this with their camera so if you know how, team 2512 will greatly appreciate your help.
