Abstract

The invention discloses a method for generating a wheat field strange circle, which comprises the steps of firstly arranging an RTK differential fixed base station on the ground, then arranging an RTK differential mobile base station on an unmanned aerial vehicle, reducing the positioning error between the unmanned aerial vehicle and the ground to +/-10 cm by using an RTK differential positioning technology, converting a pattern or character of the wheat field strange circle to be formed into a dotted XY position coordinate through a software module, converting the dotted XY coordinate into a longitude and latitude coordinate by combining longitude and latitude information of a field to be sprayed, transmitting the longitude and latitude coordinate to the unmanned aerial vehicle, and finally automatically spraying a high-concentration herbicide by the unmanned aerial vehicle according to the longitude and latitude coordinate to change the color of the sprayed field, thereby forming the wheat field strange circle.

Description

Method for generating wheat field strange circle

Technical Field

The invention relates to the technical field of unmanned aircrafts, in particular to a method for generating a wheat field strange circle.

Background

Currently, more and more advertising media and advertising means are introduced into life, but the phenomenon of the monster circle of the wheat field is gradually noticed by people as a novel advertising mode, and the advertising means of the monster circle of the wheat field is introduced by enterprises which have been on holidays or need advertising promotion. The current method for generating the wheat field odd circle is mainly generated by people walking on the wheat field, and the method is time-consuming, labor-consuming and not attractive, so that an automatic and convenient method for generating the wheat field odd circle is urgently needed to solve the problem.

Disclosure of Invention

The invention aims to provide a method for generating a wheat field strange circle, which comprises the steps of arranging an RTK differential fixed base station on the ground, arranging an RTK differential mobile base station on an unmanned aerial vehicle, reducing the positioning error between the unmanned aerial vehicle and the ground to +/-10 cm by using an RTK differential positioning technology, converting a pattern or character of the wheat field strange circle to be formed into a dotted XY position coordinate through a software module, converting the dotted XY coordinate into a longitude and latitude coordinate by combining longitude and latitude information of a field to be sprayed, transmitting the longitude and latitude coordinate to the unmanned aerial vehicle, and finally automatically spraying a high-concentration herbicide by the unmanned aerial vehicle according to the longitude and latitude coordinate to change the color of the sprayed field, thereby forming the wheat field strange circle.

In order to achieve the purpose, the invention adopts the following technical scheme: a method for generating a wheat field strange circle comprises the steps of arranging an RTK differential fixed base station on the ground, installing an RTK differential mobile base station on an unmanned aerial vehicle, reducing the positioning error between the unmanned aerial vehicle and the ground to +/-10 cm by using an RTK differential positioning technology, converting a pattern or characters of the wheat field strange circle to be formed into a dot-shaped XY position coordinate through a software module, converting the dot-shaped XY coordinate into a longitude and latitude coordinate by combining longitude and latitude information of a field to be sprayed, transmitting the longitude and latitude coordinate to the unmanned aerial vehicle, and finally automatically spraying a high-concentration herbicide by the unmanned aerial vehicle according to the longitude and latitude coordinate to change the color of the sprayed field, so that the wheat field strange circle is formed.

Compared with the prior art, the invention has the following beneficial effects:

the existing method for generating the wheat field strange circle is mainly generated by walking on a wheat field by people, and is time-consuming, labor-consuming and unattractive.

The method comprises the steps of firstly arranging an RTK differential fixed base station on the ground, then installing an RTK differential mobile base station on an unmanned aerial vehicle, reducing the positioning error between the unmanned aerial vehicle and the ground to +/-10 cm by using an RTK differential positioning technology, converting the patterns or characters of a wheat field strange circle to be formed into punctiform XY position coordinates through a software module, converting the punctiform XY coordinates into longitude and latitude coordinates by combining longitude and latitude information of a field to be sprayed, transmitting the longitude and latitude coordinates to the unmanned aerial vehicle, and finally automatically spraying high-concentration herbicide by the unmanned aerial vehicle according to the longitude and latitude coordinates to change the color of the sprayed field, so that the wheat field strange circle is formed.
