Method and device for controlling movable object, and UAV (unmanned aerial vehicle)

Abstract

A method and device for controlling a movable object, a storage medium, and a UAV (unmanned aerial vehicle) are provided. The method includes obtaining a signal strength (202) of a remote control signal transmitted to a movable object, obtaining a motion path (204) of the movable object corresponding to a signal strength less than a predetermined intensity threshold, indicating that the movable object is entering an original return mode , The moveable object returns along the motion path (206) in the return path return mode; and in response to the signal strength being greater than the intensity threshold, indicates that the movable object exits the return path return mode (208). As a result, a movable object, such as an UAV, can be re-searched for a remote control signal if the remote control signal is weak or lost, and collision of the movable object can be avoided to improve safety.

The copyright owner has no objection to the reproduction by anyone of the patent document or the patent disclosure as it exists in the official records and files of the Patent and Trademark Office. technical field [0003] Embodiments of the present invention generally relate to control technology, and in particular, relate to a method for controlling a movable object, a device for controlling a movable object, a storage medium, and an unmanned aerial vehicle. Background technique [0004] Existing movable objects are usually controlled wirelessly by an operator using a remote control. Taking an unmanned aerial vehicle (Unmanned Aerial Vehicle, UAV) as an example, when the remote control signal is good, the safety of the unmanned aerial vehicle is the responsibility of the operator. However, since the ...

AI Technical Summary

Problems solved by technology

However, since the remote control signal usually uses open frequency bands such as 2.4 / 5.8GHz, the power of the remote control signal is limited and is susceptible to interference

For example, when the remote control signal is blocked by obstacles such as hills and buildings, it is easy to be interrupted, and the interruption of the remote control signal will affect the safety of the UAV, and even cause the UAV to crash
