Embodiment 1

[0058] figure 1 A schematic flow chart showing the implementation of the tracking control method provided by Embodiment 1 of the present invention is shown. The execution subject of the embodiment of the present invention is a mobile terminal. like figure 1 As shown, the tracking control method may specifically include the following steps:

[0059] Step S101: Communicating with at least three drones that are not on the same straight line.

[0060] Among them, the fact that the UAVs are not on the same straight line is to meet the conditions of the three-point positioning principle. The mobile terminal communicates with the UAV separately, such as figure 2 As shown, the way of communication connection is not limited here.

[0061] Step S102: Obtain the first distance between each UAV and the tracked target.

[0062] Optionally, as a preferred embodiment of the embodiment of the present invention, such as image 3 As shown, the acquisition of the first distance between e...

Embodiment 2

[0084] Please refer to Figure 7 , which shows a structural block diagram of the tracking control device provided by Embodiment 2 of the present invention. The tracking control device 70 includes: a communication module 71 , a first acquisition module 72 , a first calculation module 73 , a second calculation module 74 , a second acquisition module 57 and a control module 77 . Among them, the specific functions of each module are as follows:

[0085] A communication module 71, configured to communicate with at least three unmanned aerial vehicles that are not on the same straight line;

[0086] The first acquiring module 72 is used to acquire the first distance between each drone and the tracked target;

[0087] The first calculation module 73 is used to obtain the position information of each drone, and obtain the vertical projection point of the drone to the plane where the tracked target is located based on the position information, and calculate the The second distance f...

Embodiment 3

[0102] Figure 8 It is a schematic diagram of the mobile terminal provided by Embodiment 3 of the present invention. like Figure 8As shown, the mobile terminal 8 of this embodiment includes: a processor 80, a memory 81, and a computer program 82 stored in the memory 81 and operable on the processor 80, such as a tracking control method program. When the processor 80 executes the computer program 82, it realizes the steps in the above embodiments of the tracking control method, for example figure 1 Steps S101 to S106 are shown. Alternatively, when the processor 80 executes the computer program 82, the functions of the modules in the above-mentioned device embodiments are realized, for example Figure 7 The functions of modules 71 to 76 are shown.

[0103] Exemplarily, the computer program 82 can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 81 and executed by the processor 80 to complete this invention. The one or m...

Abstract

The invention, which is applicable to the technical field of tracking, provides a tracking control method and device and a mobile terminal. The method includes: carrying out communication connection with at least three unmanned aerial vehicles arranged at different straight lines; acquiring a first distance between each unmanned aerial vehicle and a tracked target; acquiring location information of each unmanned aerial vehicle, acquiring a vertical projection point of each unmanned aerial vehicle on the plane on which the tracked target is located based on the location information, and calculating a second distance from the unmanned aerial vehicle to the vertical projection point; according to the first distance and the second distance, calculating third distances between the vertical projection points and the tracked target based on the Pythagorean theorem; according to the at least three third distances, acquiring the position information of the tracked target according to a three-point positioning algorithm; and controlling the unmanned aerial vehicles to track the tracked target based on the position information of the tracked target. Therefore, the moving tracked target can belocated accurately. The implementation process is simple; the algorithm is simple; and the practicability and usability are high.

Description

technical field [0001] The invention belongs to the technical field of tracking, and in particular relates to a tracking control method, device and mobile terminal. Background technique [0002] With the development of tracking technology, the tracking device has a greater application in the field of target tracking. The technology for tracking the target by existing tracking devices generally adopts a three-point positioning algorithm, which has the following problems: [0003] Realize three-point positioning based on the same plane to obtain the coordinates of unknown points. If one point is not on the same plane, the calculation result will be inaccurate, and the three-point positioning algorithm is only suitable for positioning unknown positions based on fixed positions, and for moving objects. Objects are positioned with low accuracy. [0004] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. Contents of the invent...
