Embodiment 1

[0052] The first aspect of the embodiment of the present invention provides a control method for drones to follow, please refer to figure 1 , is a flow chart of the control method for the drone to follow in the embodiment of the present invention. The method includes:

[0053] 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.

[0054]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 objects) feedback p...

Embodiment 2

[0091] Based on the same inventive concept as the control method for 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:

[0092] 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;

[0093] An acquisition module 202, configured to acquire images in a preset range corresponding to the indicated position;

[0094] 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;

[0095] 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 adjust th...

Embodiment 3

[0105] Based on the same inventive concept as the control method followed by the UAV 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:

[0106] 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;

[0107] acquiring an image of a preset range corresponding to the indicated position;

[0108] judging whether the image contains the target object, and if so, obtaining the current display position of the target object in the image;

[0109] 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 o...

Abstract

An embodiment of the invention provides a UAV following control method and device. The control method comprises that according to a primary navigation signal of a target object, a UAV is controlled tofly to a position indicated by the navigation signal; an image of a preset range corresponding to the indicated position is obtained; whether the image includes the target object is determined, and if YES, a present display position of the target object in the image is obtained; and when the present display position is different from the preset display position, a control parameter of the UAV isadjusted according to relative position information of the present and preset display positions, so that the display position of the target object is kept in the preset display position. The target object is followed accurately.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a control method and device for following the unmanned aerial vehicle and the 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 can be s...
