Sistema per la rappresentazione di una immagine grafica su una superficie di un supporto per mezzo di aeromobili a volo autonomo

A system for representing a graphic image on a surface of a support by painting surface (S) areas or drawing signs, of a predetermined shape and position, is described, characterised in that it comprises: at least one autonomous flight aircraft (200) adapted to hover in one semi-space in front of the surface (S) and equipped with a spraying device (250) arranged to selectively apply at least one coating substance on at least one portion of the surface (S); a system (300) for positioning the aircraft with respect to a predetermined reference system associated with the surface (S); a processing system (100) arranged to calculate at least one spatial flight trajectory of the aircraft (200) so that the projection thereof on the surface includes a predetermined path of application of the coating substance on the surface (S) adapted to create at least one representation area of the image; and a system (220, 240) for driving the aircraft (200), adapted to receive the aforesaid flight trajectory of the aircraft (200) and arranged to control the movement of the aircraft (200) along the flight trajectory together with the selective action of the spraying device according to the instantaneous position of the aircraft (200) by comparison with a predetermined path of application of the coating substance on the surface (S).
