Experience real-time object detection and person tracking with your little DJI Ryze Tello Drone.
"Tello Vision 1D" allows 1D person tracking making Tello rotate as the detected person moves. It can even rotate to search for persons than follow them.
If more than one person is detected it follows persons' horizontal positions barycenter.
It records 960x720 video at 30 fps in mp4 format (without detection boxes overlay).
With "Tello Vision 1D" test your smartphone capabilities in real-time object detection. Inference time must be less than 100 ms and won't work properly on older smartphones.
Have fun!!!
