Abstract
This method, applicable in particular to radio-controlled toys comprises the operations consisting in: fitting the drone with a telemeter and a video camera; acquiring the altitude of the drone relative to the ground by means of a telemeter; acquiring the horizontal speed of the drone; and automatically stabilizing the drone in hovering by: servo-controlling the vertical thrust force of the drone so as to stabilize the altitude acquired by the telemeter; and servo-controlling the horizontal thrust force of the drone so as to obtain zero horizontal speed. The video camera is a front-sight camera pointing towards the front of the drone; and the horizontal speed of the drone is acquired from a plurality of video images captured by said front-sight camera.
