Embodiment 1

[0027] An embodiment of the present invention provides a method for controlling the landing of a UAV, which can be applied to the landing and recovery of a fixed-wing UAV. The method for controlling the UAV landing provided by the present invention improves the accuracy of the UAV recovery through corresponding control operations during the UAV recovery process.

[0028] Such as figure 1 As shown, the control method of the UAV landing provided by the embodiment of the present invention includes:

[0029] S101. The drone acquires a recovery instruction, and determines a designated landing point according to the recovery instruction.

[0030] In an implementation manner, the UAV acquires the recovery instruction, which specifically includes: acquiring a ground image within a preset range below the UAV, and identifying a coded label in the ground image.

[0031] Wherein, the coding label is set at the position of the designated landing point.

[0032] Exemplarily, a high-defin...

Embodiment 2

[0070] Based on the above method for controlling the landing of a drone, an embodiment of the present invention provides a drone 30 . Such as image 3 As shown, the UAV 30 includes: a navigation module 301, a distance detection module 302, a flight control module 303, and a judgment module 304, wherein:

[0071] A navigation module 301, configured to obtain a recovery instruction, and determine a designated landing point according to the recovery instruction;

[0072] A distance detection module 302, configured to detect the horizontal distance between the UAV and the designated landing point;

[0073] The flight control module 303 is also used to perform a deceleration operation after determining that the horizontal distance between the UAV and the designated landing point satisfies a preset condition;

[0074] The flight control module 303 is also used to control the reverse rotation of the engine of the UAV to provide reverse thrust to the UAV when it is determined that t...

Abstract

The invention provides a control method for UAV landing and a UAV, relating to the control field of UAVs. The embodiment of the invention can realize automatic recovery of the UAV, and can improve therecovery precision through carrying out corresponding control operations in the recovery process of the UAV. The method comprises the steps of: acquiring a recovery instruction by means of the UAV, and determining a designated landing point according to the recovery instruction; detecting a horizontal distance between the UAV and the designated landing point; performing a deceleration operation after determining that the horizontal distance between the UAV and the designated landing point meets a preset condition; controlling an engine of the UAV to rotate reversely when determining that a flight speed of the UAV is reduced to be within a preset speed range, so as to provide the UAV with reaction thrust; determining whether flight parameters of the UAV meet recovery requirements after theUAV enters a preset region; and executing a landing operation after determining that the flight parameters of the UAV meet the recovery requirements. The control method is used for controlling the UAV.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle control, in particular to a method for controlling the landing of an unmanned aerial vehicle and the unmanned aerial vehicle. Background technique [0002] Compared with take-off, drone recovery is a more complex and more prone to failure stage. Whether it can land safely has become an important indicator for evaluating the performance of drones. At present, the recovery methods of drones mainly include parachute recovery, net impact recovery, landing gear pulley landing, and aerial hooking. [0003] Among them, the UAV collision net recovery method is an ideal precise point recovery method, which is especially suitable for small fixed-wing UAVs to be used in narrow recovery sites, for example, this method is often used on ships. [0004] However, the inventor found that in the current prior art, the UAV lacks an accurate and efficient deceleration method, and the recovery control distance ...
