#Coding4Fun – How to control your #drone with 20 lines of code! (9/N)

Hi! Let’s take some Frames Per Second measurements on the UDP and OpenCV connection. It seems that working with simple movements, the values moves between 30 and 60 FPS. Just added a couple of lines in the main While, to calculate the FPS. As a final note, just need to mention that I make some — read more
