Hi everybody,
I am a student from University of L'Aquila I am writing because I am doing an analysis of flowdeck's drivers for a crazyflie 2.0 project. I am analyzing flowdeck.c in the crazyflie firmware. I think that I have understood how deltax and deltay variables are computed (by pixel accumulation from the initial position).
But I do not understand how pixel measurements of deltax and deltay are converted into meters and where this conversion is computed in the code.
Could someone help me?
Hi,Anastasia

Hi,
The pixels moves are converted in meter in the kalman filter: https://github.com/bitcraze/crazyflie-f ... an.c#L1002. The different parameters where found by doing test and measurements with an actual sensor.
