Embodiment 1

[0054] The first aspect of the embodiments of the present invention provides a method for controlling the flight of a drone. Please refer to figure 1 , Is a flowchart of a method for controlling the flight of a drone in an embodiment of the present invention. The method includes:

[0055] First, step S101 is performed: according to the primary navigation signal of the target object, the drone is controlled to fly to the position indicated by the primary navigation signal.

[0056] It should be noted that the "primary navigation signal" here refers to the navigation signal of the target object acquired for the first time. The basic target object mentioned in the following refers to the real target object that has not yet been determined whether it is the real target object that needs to be followed, and the standard target object is the real target object that has been determined to be the real target object that needs to be followed. In order to accurately track the target object ...

Embodiment 2

[0093] Based on the same inventive concept as the method for controlling drone flight in the aforementioned first aspect, the second embodiment of the present invention also provides a control device for drone following, such as figure 2 Shown, including:

[0094] The control module 201 is used to control the drone to fly to the position indicated by the navigation signal according to a navigation signal of the target object;

[0095] The acquiring module 202 is configured to acquire an image of a preset range corresponding to the indicated position;

[0096] The determining module 203 is configured to determine whether the target object is included in the image, and if so, obtain the current display position of the target object in the image;

[0097] The adjustment module 204 is configured to, when there is a difference between the current display position and the preset display position, obtain the relative position information between the current display position and the preset di...

Embodiment 3

[0107] Based on the same inventive concept as the method for controlling the flight of a drone in the first embodiment, the third embodiment of the present invention also provides a computer-readable storage medium, such as image 3 As shown, a computer program is stored thereon, and the following steps are implemented when the program is executed by the processor:

[0108] According to a navigation signal of the target object, control the drone to fly to the position indicated by the navigation signal;

[0109] Acquiring an image of a preset range corresponding to the indicated position;

[0110] Determine whether the target object is included in the image, and if so, obtain the current display position of the target object in the image;

[0111] When there is a difference between the current display position and the preset display position, the relative position information between the current display position and the preset display position is acquired, and the control parameters of...

Abstract

The embodiment of the invention provides a method and device for controlling flight of an unmanned aerial vehicle. The control method comprises the steps that according to a primary navigation signalof a target object, the unmanned aerial vehicle is controlled to fly to the position indicated by the navigation signal; an image of a preset range corresponding to the indicated position is acquired;whether or not the target object is contained in the image is judged, and if yes, the current display position of the target object in the image is acquired; and when the current display position isdifferent from the preset display position, control parameters of the unmanned aerial vehicle are adjusted according to relative position information of the current display position and the preset display position to enable the display position of the target object to keep at the preset display position. According to the method and device, the technical advantage of precisely following the targetobject is achieved.

Description

Technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to a method, a device and an unmanned aerial vehicle for controlling the flight of an unmanned aerial vehicle. Background technique [0002] With the development of UAV technology, UAVs are widely used in military reconnaissance, disaster area rescue, address exploration and other fields. In the above application fields, target tracking has become a research hotspot of UAV technology. [0003] In the prior art, a GPS (Global Positioning System) module is usually set on the following target to obtain the position information of the target, and then adjust the flying state of the drone accordingly to follow the target. However, due to the positioning accuracy of GPS Limited, it is impossible to accurately obtain the position information of the target, which leads to the problem that the target disappears or cannot be followed during the following process. [0004] It ...
