Vision positioning system
This positioning system consists of the visible light camera and the ultrasonic module. The former
is used to obtain the position information of the flight to provide reference for the horizontal
direction of the aircraft. And the latter will judge the current flight height to provide reference for
the height from the ground to maintain the flight at a certain height.
This system is adaptable to the environment in which the height is lower than 6 meters, where
there is no GPS signal or the GPS signal is not good enough. It is particularly suitable for indoor
flight.
