Toy drone with autopilot barcode reader
Appendix
I confirmed that a software normary move on Ubuntu 19.10 on Oracle VirtualBox VM. but, You should care network probrem about Python to Tello connection. If you see a blackscreen on this applications camera moniter and can control Tello, You should try change setup VirtualBox network tab. It change to type of "NAT" to "Bridge", then has possibile success a camera moniter.

Environmental configuration
The code is based on python2.7. and many import packages. (You will little struggle to reproduce the environment.) I wrote memorandum in ENVIRONMENT.TXT. (If you reference on it, you can reproduce.)
About "libh264decoder.so".
The "libh264decoder.so" is commited with binary. but, It couldn't runnning on environment, frequently. so, If you have trouble about "libh264decoder.so" with function call python. You need build to "libh264decoder.so" of H.264 vide decoder. There source is repositorie of below place, in "Tello-Python/Tello_Video/h264decoder/" dir. https://github.com/dji-sdk/Tello-Python You can build it, follow "Tello-Python/Tello_Video/h264decoder/CMakeLists.txt"
Print out the AR marker and bigger barcode.
I prepared pdf file to print out with common A4 paper, in "BarCodesAndMarkers_PrintSample.zip". Stick it on the wall, please devise.
