There is an example in Program Files/National Instruments/LabVIEW 2011/Examples/FRC/Vision called Servo Camera Example. It detected the pink and green fabric and aimed the servo at it. It is a bit difficult to setup, runs on the cRIO, but includes most of the code you are looking for provided you are only aiming the camera and hobby servos will work. If you are rotating a heavier mass, you will need a motor with more torque and you'll need an encoder or other sensor that gives feedback.
