Problems solved by technology

[0004] At present, in the search and positioning of unmanned aerial vehicles in the prior art, some use single-machine search and positioning, but there are errors in the attitude sensor, GPS positioning system, etc., so that the single-machine positioning accuracy is not high.
[0005] In some occasions, multi-machine search is used, which has disadvantages such as high cost and waste of resources.
[0006] In the process of using visual positioning in multi-machine search, the image data is two-dimensional data and cannot effectively establish an accurate viewing angle, which brings difficulties for precise target positioning

Embodiment 1

[0021] Such as figure 1 As shown, the UAV search and positioning method for targets in the wilderness: two search UAVs (1a, 1b) are used to search for target information in the wilderness, and wirelessly transmit to the receiving base station (2), and the receiving base station (2) performs target Positioning iterative calculation, quickly and accurately obtain target positioning information.

Embodiment 2

[0023] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0024] see figure 2 , the search drone (1a, 1b) includes a drone flight mechanism (101), a strapdown inertial navigation sensing system (102), a high-definition camera (103), a height sensor (104), a GPS positioning system (105), a central controller (106) and a wireless communication system (107), the central controller (106) is respectively connected with the strapdown inertial navigation sensor system (102), high-definition camera (103 ), an altitude sensor (104), a GPS positioning system (105), a central controller (106) and a wireless communication system (107) are connected and installed together on the drone flight mechanism (101).

[0025] see image 3 , the specific operation steps of the positioning iterative calculation method are as follows:

[0026] Assume that the target in the three-dimensional coordinate map is point T, and the starting points of the t...

Abstract

The invention discloses an unmanned aerial vehicle searching and positioning method for a field target. According to the method, two searching unmanned aerial vehicles are used for searching the target in the field, and visual images can be transmitted through wireless systems of the two searching unmanned aerial vehicles. When the target is determined, positioning iterative computations are carried out to obtain specific positioning information of the field target through multiple-point visual point switching of the unmanned aerial vehicles according to gesture information, height information and GPS positioning information of the unmanned aerial vehicles. The searching and positioning method can be widely applied to target positioning in unmanned aerial vehicle target searching.

Description

technical field [0001] The invention relates to the field of robot search, in particular to an unmanned aerial vehicle search and positioning method for wilderness targets. Background technique [0002] With the promotion of drone applications, wilderness target search has gradually become a hot application. [0003] In wilderness target search, the speed and accuracy of target positioning are important evaluation indicators for target search and positioning. [0004] At present, in the search and positioning of unmanned aerial vehicles in the prior art, some use single-machine search and positioning, but there are errors in the attitude sensor, GPS positioning system, etc., so that the single-machine positioning accuracy is not high. [0005] In some occasions, multi-machine search is used, which has disadvantages such as high cost and waste of resources. [0006] In the process of using visual positioning in multi-machine search, the image data is two-dimensional data an...
