METHOD OF PILOTING A ROTARY-WING DRONE WITH AUTOMATIC STABILIZATION OF HOVERING FLIGHT
First Claim
1. A method of piloting a rotary-wing drone with automatic stabilization of hovering, the method comprising the steps 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 method being characterized in that;
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.

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.
