MAVs have a lower performance than the Odroid processor.  We decided to use the quadcopter \emph{Parrot Bebop Drone}  as prototype for all our tests. This UAV In general, quadcopters  allow for navigating in arbitrary directions without changing its their  yaw angle. Additionally, several models show stable flight behavior, resulting in noise-free  images. It The \emph{Parrot Bebop Drone}  is equipped with a lithium-ion polymer battery  that allows for approximately 11 minutes flying time. The UAV's dimensions are $28 \times 32 \times 3.6$\,cm and it weighs 400\,g. The UAV is equipped with two cameras: a front camera and a downward-looking bottom camera. The proposed approach makes use of the  bottom camera only. This camera has a resolution of $640 \times 480$  pixels with a frequency of 30 frames per second. The UAV's processor
