Shreyas and Marcus recently started learning about computer vision in a robotics class, and had learned how to recognise faces and objects using OpenCV. They were looking for ways to use this knowledge when Shreyas discovered that the Tello's actually had capability to use the onboard cameras for image recognition. He quickly wrote a program to use this capability, and it was a great success. Students learned about computer vision in the Week 7 class and were able to have the drone land when it recognised a red marker.
Shreyas and Marcus plan to further develop this concept by using OpenCV and the DJI SDK to detect objects, then accordingly move the drone into the right coordinate on a 3x3 grid to have the object be in the center of the image.
