Code for making a AR drone 2.0 fly above a red circle all by itself using openCV and python 2.7
NOTE: I modded the AR-Drone by getting the front camera of the AR-Drone and taped it to the bottom center of the drone. If you do it correctly the existing flex cable is just long enough! This is because the normal AR-Drone bottom camera is very low resolution. If you want to run this code also make sure to do this mod!
NOTE 2: You might have to help the drone a little bit at takeoff. This is because the AR-Drone drifts a lot at takeoff and because of that it could lose sight of the Circle. Just push the drone into the direction of the circle when it takes off.
