Embodiment 1

[0050] The first aspect of the embodiment of the present invention provides a method for controlling UAV following, please refer to figure 1 , is a flow chart of the method for controlling the following of the drone in the embodiment of the present invention. The method includes:

[0051] First, step S101 is executed: 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.

[0052] It should be noted that the "one navigation signal" here refers to the navigation signal of the target object acquired for the first time. The basic target object described below refers to the real target object that has not been determined whether it needs to be followed, and the standard target object refers to the real target object that has been determined to be followed. In order to accurately track the target object and exclude the influence of other non-true target objects (interfering object...

Embodiment 2

[0089] Based on the same inventive concept as the method for controlling UAV following in the aforementioned first aspect, Embodiment 2 of the present invention also provides a control device for UAV following, such as figure 2 shown, including:

[0090] The control module 201 is used to control the UAV to fly to the position indicated by the navigation signal according to a navigation signal of the target object;

[0091] An acquisition module 202, configured to acquire images in a preset range corresponding to the indicated position;

[0092] A judging module 203, configured to judge whether the target object is included in the image, and if so, obtain the current display position of the target object in the image;

[0093] An adjustment module 204, configured to acquire relative position information between the current display position and the preset display position when there is a difference between the current display position and the preset display position, and adjus...

Embodiment 3

[0103] Based on the same inventive concept as the method for controlling UAV following in the first embodiment, the third embodiment of the present invention also provides a computer-readable storage medium, such as image 3 As shown, there is stored thereon a computer program which, when executed by a processor, implements the following steps:

[0104] According to a navigation signal of the target object, the unmanned aerial vehicle is controlled to fly to the position indicated by the navigation signal;

[0105] acquiring an image of a preset range corresponding to the indicated position;

[0106] judging whether the image contains the target object, and if so, obtaining the current display position of the target object in the image;

[0107] When there is a difference between the current display position and the preset display position, the relative position information of the current display position and the preset display position is obtained, and the control parameters...

Abstract

The embodiment of the invention provides a method and device for controlling follow of an unmanned aerial vehicle. The control method comprises the steps that basic category information of a basic target object is acquired; whether or not the target object is a standard target object needing to be followed is judged; if yes, the basic target object is marked as the standard target object, and according to a primary navigation signal of the standard 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 is different from the preset display position, control parameters of the unmanned aerial vehicle are adjusted according to relative position information ofthe 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 target object is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and device for controlling the following of an unmanned aerial vehicle and 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 following has become a research hotspot of UAV technology. [0003] In the prior art, a GPS (Global Positioning System) module is usually installed on the following target to obtain the position information of the target, and then adjust the flight status of the UAV accordingly to follow the target. However, due to the positioning accuracy of GPS Limited, the location information of the target cannot be obtained accurately, resulting in the problem that the target disappears or cannot be followed during the following process. [0004] It...
