Boundary modeling method of polygonal farmland operation area

Abstract

The invention discloses a boundary modeling method of a polygonal farmland operation area. The method comprises the steps that n peaks of the boundary of the polygonal farmland operation area are collected; the n peaks are put at a first quadrant of a rectangular coordinate system; the peak with the biggest X-coordinate value and the peak with the smallest X-coordinate value are determined; an upper boundary function model and a lower boundary function model are established, and boundary modeling is completed. According to the method, the boundary of the linear polygonal farmland operation area and the peaks of obstacles in the farmland operation area can be recorded and drawn precisely, so that the accurate farmland operation area is provided for an operator of an agricultural plant protection machine, and a reliable basis is provided for the path and track planning of the agricultural plan protection machine and the calculation of farmland operation area.

Description

technical field [0001] The invention relates to a polygonal farmland operation area boundary modeling method. Background technique [0002] With the continuous development of science and technology, the use of modern machinery to replace manual labor has become a popular trend in all walks of life. As a traditional large agricultural country, our country has a very large area of ​​arable land. However, at present, traditional manual methods are still used in domestic farmland operations. Among them, pesticide spraying adopts the method of artificial spraying, which is not only inefficient, but also has great physical and mental harm to the workers. Therefore, advanced technology is urgently needed to change this phenomenon. Agricultural plant protection machines have emerged as the times require. However, all plant protection machines today are operated manually, and the spraying area and boundary of the farmland are judged entirely by the operator's eyes, which inevitably ...

AI Technical Summary

Problems solved by technology

When this farmland outline map is used for the path and track planning of agricultural plant protection machine spraying pesticides, there will be excessive spraying in non-operation areas, which will waste pesticides; The calculation is inaccurate; the existing method does not establish a mathematical model for the boundary of the farmland area, so it cannot provide a reliable basis for the path and track planning of the farmland operation area; the vertices of obstacles that may exist in the farmland operation area (such as utility poles, Trees, signal towers, etc.), when the farmland outline map is used for agricultural plant protection aircraft spraying pesticide paths and track planning, it may cause the agricultural plant protection aircraft to collide or crash.
