Example Embodiment

[0030] A node deployment and positioning method for drone inspection in ecological environment includes:

[0031] 1. The UAV 110 navigates through the navigation system, and airdrops multiple node sensors 120 to corresponding preset airdrop areas.

[0032] 2. Using the quadrilateral measurement method, the UAV 110 itself is used as the anchor node to locate each node sensor 120 of the airdrop:

[0033] 1. The UAV navigates through the navigation system and flies to four different positions as four anchor nodes. The four anchor nodes are not coplanar, and the coordinates of the four are A respectively. a (x a ,y a ,z a ), A b (x b ,y b ,z b ), A c (x c ,y c ,z c ) And A d (x d ,y d ,z d ), see figure 2 , O in the figure represents the node sensor, and the coordinates of the anchor node are provided by the Beidou positioning system;

[0034] 2. Detect the distance d between the anchor node and the node sensor 120 a ,d b ,d c And d d , The traditional TOA algorithm has relatively high re...

Abstract

The invention relates to a node deployment and positioning method for patrol inspection of an unmanned aerial vehicle (UAV) in an ecological environment, which comprises the following steps: airdropping a plurality of node sensors to a corresponding preset airdrop area respectively by the unmanned aerial vehicle through navigation system navigation; and positioning each node sensor which is airdropped through using the unmanned aerial vehicle as an anchor node. The method has high positioning accuracy, and the formed wireless sensor network does not require to re-set the anchor node and carryout positioning, thus saving cost and power consumption.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle inspection, and in particular relates to a node deployment and positioning method for ecological environment unmanned aerial vehicle inspection. Background technique [0002] UAV is a powered, controllable, unmanned aerial vehicle that can carry multiple mission equipment, perform multiple tasks, and can be reused. It has many advantages such as low cost, low loss, reusability and low risk. ,with broadly application foreground. In recent years, the application of UAVs in environmental monitoring is generally divided into three categories. The first category uses drones for low-altitude remote sensing to perceive environmental changes, the second category directly installs special sensors on drones to realize environmental perception, and the third category uses drones to airdrop measurement equipment. [0003] There are already many algorithms for the above three types of researc...
