摘要:
A UAV is provided to cancel background noise from audio data collected by the UAV. The UAV is provided with one or more background microphones in a proximity of one or more background noise-producing components. The UAV is also provided with one or more audio source collecting microphones. The audio data collected by the background microphones may be used to reduce or cancel interfering background noise from the audio signal detected by the audio source collecting microphone. The target audio may be captured or recorded with little or no background noise.

The present invention discloses an unmanned helicopter, and belongs to the technical field of unmanned aerial vehicles. The unmanned helicopter includes an air inlet system, an exhaust system, a cooling system and a dynamic balance system. The air inlet system is fixed on a second side; the exhaust system is fixed on a third side; and the cooling system is fixed on a first side, and the dynamic balance system is fixed on a tail. The airflow at the outside of the unmanned helicopter flows into the air inlet system smoothly, quickly and efficiently under the action of its own flow velocity relative to the unmanned helicopter, therefore the technical problem in the prior art that the air entering the fuselage with a unit volume is burnt insufficiently, which generates adverse effects on the normal flight of the unmanned helicopter, is solved.

An unmanned aerial vehicle (UAV) copter for consumer photography or videography can be launched by a user throwing the UAV copter into mid-air. The UAV copter can detect that the UAV copter has been thrown upward while propeller drivers of the UAV copter are inert. In response to detecting that the UAV copter has been thrown upward, the UAV copter can compute power adjustments for propeller drivers of the UAV copter to have the UAV copter reach a predetermined elevation above an operator device. The UAV copter can then supply power to the propeller drivers in accordance with the computed power adjustments.

The invention relates to a method for optically detecting a wind turbine (1) for testing purposes using an aircraft, in particular a manned or unmanned rotorcraft (9) equipped with at least one camera. The wind turbine comprises multiple rotor blades (2), the surface of which is scanned as part of the method, said scan being carried out optically. The method has the following method steps: aligning a first rotor blade (2 1 ) in a vertical position, then departing and scanning a first face (5) of the first rotor blade (2 1 ) in the vertical direction, then departing and scanning a second face (6) of the first rotor blade (2 1 ) in the vertical direction, then aligning a second rotor blade (2 2 ) in a vertical position, then departing and scanning a first face (5) of the second rotor blade (2 2 ) in the vertical direction, and then departing and scanning a second face (6) of the second rotor blade (2 2 ) in the vertical direction.
