In this course Pat Ryan demonstrates two powerful concepts using OpenCV with Tello. The first is called "point n click" flying. This feature is very similar to the popular "TapFly" feature available in many of DJI's drones. You will learn how to capture the coordinates of a mouse click in the video window and command Tello to fly to this location.

You will also learn how to detect ArUco markers using the OpenCV contrib module. ArUco markers are similar to QR codes that allow algorithms to quickly decode information stored in the marker. In this course you will learn how to detect the marker ID, draw boundaries around the marker, determine the center, and have Tello track (or follow) the marker.

Please make sure you have gone through Pat's introductory course that shows how to setup your development environment. All code for this course is located in the following GitHub repository:
