Definitions
- the present invention relates to a guidance system for guiding an aircraft, in particular an autonomous aircraft, along at least one portion of an air route.
- Remote controlled drones are thus known by means of a remote control device or a mobile tablet on which adapted software is executed, the ground pilot receiving the images taken by an on-board camera, in real time, for piloting of the drone.
- the control signals necessary for driving this drone are typically sent by radiofrequency (RF) link.
- RF radiofrequency
- drones equipped with an autopilot system allowing them, outside, to follow a predefined path and eventually return to their initial GPS position.
- GPS satellite signal receivers for these drones to determine their position have a greater or lesser reliability.
- the drone can thus land several meters from its starting point or drift in static flight which forces the pilot to pay particular attention.
- the line of sight of the satellites necessary for the reception of a signal is at least partially masked so that the GPS signals are strongly attenuated, or even null.
- drones can not maintain their position and quickly hit the first obstacle, such as a wall.
- the impossibility of determining the position of a drone is incompatible with a flight in complete autonomy.
- interference with the presence of electrical devices in the building can interfere with the reception or transmission of the RF signals necessary for driving the drone.
- drones are equipped for the internal flight of an on-board camera, which is oriented downwards for the acquisition of ground reference points.
- obstacles outside the field of the camera can damage the drone or even drop it when one or more of its propellers are hit.
- the fall of a drone can not only cause irreversible damage to the drone, but can also injure one or more people placed at the point of impact on the ground.
- the blades of a rotary wing drone are sharp elements at high speed.
- the present invention relates to a system for guiding an aircraft, such as an autonomous aircraft, along at least a portion of an air route, simple in its design and in its operating mode, economical and reliable, to facilitate the navigation of this aircraft.

- RTH return to home
- the engine or engines of this aircraft can be enslaved in position so that it follows a path that has been determined by one or more air guide lines and optionally one or more light beams.

- the tracking means of the aircraft comprises, on the one hand, a mechanical detection device by contact making it possible to follow this line 20 of aerial guidance, which is, for example, placed under the fuselage of the aircraft and secondly , an on-board image sensor capable of taking a sequence of images of an observation zone to enable the detection and identification of a light beam 21.
- the tracking means also includes a calculating unit for individually controlling the mechanical detection device and the image sensor and switching from one to the other depending on the nature, physical line or light beam, the portion of the air route followed at any given time.
- the calculation unit advantageously comprises a processor and software instructions which, when executed by this processor, enable the steps of an image processing method to be used to identify the light beam 21 on the images taken by the sensor. image.
- the calculation unit is able to determine in real time the relative position of the aircraft with respect to this marker.
- the tracking means of the aircraft could be limited to only one set comprising the image sensor and the computing unit, the aircraft then being guided along the portion of the air route by detection on the acquired images.
