  • Publication number: 20180048827
    Abstract: The invention relates to a method for capturing a video using a camera on board a fixed-wing drone, the camera comprising an image sensor, the drone having, during flight, a drift angle between the longitudinal axis of the drone and a flight direction of the drone. This method comprises: determining the drift angle of the drone; and obtaining video by image acquisition corresponding to a zone with reduced dimensions relative to those of the image sensor, the position of the zone being determined as a function of the drift angle of the drone.

  • Publication number: 20180048828
    Abstract: The invention relates to a method for capturing a video using a camera on board a fixed-wing drone, the camera comprising an image sensor, the fixed-wing drone comprising an inertial unit configured to measure the roll angle, the pitch angle and/or the yaw angle of the fixed-wing drone 57858. This method comprises obtaining one or more images corresponding to a zone of the sensor with reduced dimensions relative to those of the sensor and associated with a shot reference, the position of the zone being determined from the orientation of the shot reference obtained as a function of the roll angle, the pitch angle and/or the yaw angle of the fixed-wing drone.

  • Publication number: 20180039272
    Abstract: A module for a drone that integrates an electronic circuit and one or more sensors for the attitude, altitude, speed, orientation and/or position of the drone in the same one-piece housing. The module also integrates an electronic power circuit that receives set command values prepared by the processor of the electronic circuit on the basis of the data provided by the integrated sensors and provides, as an output, corresponding signals for directly supplying current or voltage to the propulsion means of the drone and to the control surfaces.

  • Publication number: 20180039271
    Abstract: A drone that includes an automatic piloting system that receives internal and/or external piloting instructions, as well as data of instantaneous attitude (?*, ?*), altitude (z*) and speed (V*) delivered by sensors. Set point calculation circuits calculate, as a function of a model of the aerodynamic behaviour of the drone in flight, roll (?) and/or pitch (?) set points and/or speed set points (V) and/or altitude set points (z) corresponding to the internal and/or external piloting instructions received. Correction and control circuits control the propulsion system and the drone control surface servomechanisms. A system further allows generating internally piloting instructions for autonomous flight modes such as automatic take-off or automatic landing.

  • Publication number: 20170267372
    Abstract: Disclosed are embodiments of a drone with a flattened tubular part protrudingly mounted on a module located on the fuselage of the drone, where the free distal end of the drone may also include a Pitot tube dynamic pressure front air intake. An internal duct may further connect the air intake to a pressure sensor mounted on the module. The tubular part may be mobile with respect to the module and may further include a means or mechanism for the mechanical coupling to a contractor mounted on the module. The tubular part may further include a light guide in light communication with a luminescent element mounted in the vicinity or at the level of the proximal end thereof. The tubular part may also include two sectionalized portions that are nested and in continuation of each other, where the base portion may be permanently linked to the module and a removable protruding portion may be located at the top base portion, which may include a front air intake and an internal duct.
