tello-test's Introduction

DJI Tello test

This repo was created to do some PoCs to place all toghrther: Go, DJI Tello drone, gobot and gocv

/facetracking

This is a simple program that just let the Tello drone detect a face and follow it automatically. You can also control the Tello drone from the keyboard Stack:

OpenCV (via gocv) and caffe (for face detection)
https://gobot.io/documentation/platforms/keyboard/
https://gobot.io/documentation/platforms/tello/
ffmpeg for video compression

Set up

Before starting, you must have installed:

ffmpeg
OpenCV: it can be installed by installing gocv https://gocv.io/getting-started/

How to run it?

First, connect to the drone's Wi-Fi network from your computer. It will be named something like "TELLO-XXXXXX". Then, run the program: go run ./facetracking/facetracking.go

How it works?

Once program is started it, opens a window where video from the Tello drone will be streamed.

It is also listening for any key pressed on the console to control the drone:

Key	Action
1	take off
2	take off by throwing it up
Q	land
⬅	rotate left
➡	rotate right
⬇	go down
⬆︎️	go up
W	forward
S	Backward
A	Left
D	Right
T	Start / Stop face tracking
B	Battery indicator
X	Stats (flight data)
Spacebar	Hover
ESC	Quit Program

So, you need to:

run the program
then take off (1 or 2)
put your face in front of the Tello camera (you should see a rectangle in the video window)
then start tracking (T)
Move yourself so the drone can follow you (consider slow movements as this program is not optimized yet to support very fast movements)
Once you are done, then press T again to let the drone stop tracking
