Irregular small-sized land area measuring method based on photoelectric measuring technology

Abstract

The invention discloses an irregular small-sized land area measuring method based on a photoelectric measuring technology. The irregular small-sized land area measuring method is characterized by comprising the following steps: 1) determining a positioning base point in a land central area; 2) building laser beams which are vertical to one another on the basis of the positioning base point in order to partition a land into four areas; 3) erecting a measuring cable along an outer edge of each area, wherein photoelectric measuring instrument modules are distributed on the measuring cable at equal intervals; 4) acquiring distances between the photoelectric measuring instrument modules and the positioning base point, and transmitting the distances to a control terminal; 5) calculating a land graph and an area according to data acquired through the distances among photoelectric measuring instruments through the control terminal. By adopting the irregular small-sized land area measuring method based on the photoelectric measuring technology, distance information acquired by the photoelectric measuring instruments which are arranged along the edges of the land is utilized in conjunction with equal-interval arrangement of adjacent photoelectric measuring instruments, so that a coordinate graph of the land edges can be drawn, and high boundary annotation accuracy and high size control accuracy are realized; the method is easy and convenient to operate, and contributes to proceeding of outdoor operation.

Description

technical field [0001] The invention relates to a measurement method for irregular small-scale land area based on photoelectric measurement technology. Background technique [0002] Rational planning and utilization of rural land is an important step in the development of my country's agricultural economy. Therefore, the arrangement of land resources must first start with the measurement of land area. GPS area measuring instrument is based on GPS technology to realize the measurement and recording of farmland land area, which provides help for agricultural production and land rational planning and utilization. Finding out the quantity, distribution and utilization status of land resources, and giving a scientific evaluation of its utilization structure, in order to better develop and utilize land resources rationally, and provide scientific basis for agricultural division and land use planning, has become a very important task. Task. Over the past few years, we have traine...
