Abstract

The invention provides a return flight control method and device of an unmanned aerial vehicle, a storage medium and electronic equipment. The return flight control method of the unmanned aerial vehicle comprises the following steps: in response to a return flight instruction, reducing the flight speed of the unmanned aerial vehicle to below a preset threshold at a preset acceleration; and controlling the unmanned aerial vehicle to fly to a specified position and vertically land from the specified position. After the unmanned aerial vehicle is switched to a return mode, the speed of the unmanned aerial vehicle is uniformly reduced at the preset acceleration, and the return is performed after the speed of the unmanned aerial vehicle is reduced, so that the unmanned aerial vehicle can stablycomplete the switching of the working mode, and the problem that the attitude change amplitude of the unmanned aerial vehicle is too large due to the sudden change of the speed after the return modeis switched is avoided.

Description

technical field [0001] The present invention generally relates to a UAV technology, and specifically relates to a UAV return control method and device, a storage medium, and electronic equipment. Background technique [0002] With the development of drone technology and the gradual maturity of control systems, more and more rotor drones are used in logistics, security, plant protection, inspection and other fields. Taking the logistics UAV as an example, when the UAV is performing autonomous tasks, when it encounters special circumstances such as bad weather, it needs to return to ensure that the UAV returns to the ground safely. [0003] At present, the pilot (UAV operator) generally takes over the UAV and controls the UAV to land at the designated location. When the pilot takes over the UAV, it is prone to flight instability caused by a sudden change in speed; in addition, the effective control distance of the manual return is limited by the communication distance of the ...
