I want to do https://www.youtube.com/watch?v=bbCi5LN8Usw23
As I knew this question had been asked before as following
"Those demonstration uses custom firmwares, and all drones are completely autonomous during the demonstration.
Such firmwares uses components not available in the official firmware (such as 3d positionning using the square patterns on the ground and image processing from the bottom facing camera), so you won't be able to do the same with the official firmware.
However, the BIG QUESTION is: How I can get or buy that custom firmware that allow me to do image processing and perform such show?
Can I start with this? https://github.com/Parrot-Developers/mambo-opensource
As I knew somebody tried to do that before but got some problem as mentioned in this post
