Agricultural machinery operation area calculation method based on path point analysis

Abstract

An agricultural machinery operation area calculation method based on path point analysis comprises the steps that a GPS data acquisition device is installed in the center of the top of agricultural machinery, longitude and latitude data of agricultural machinery driving and operation path points are acquired and recorded in real time, and longitude and latitude coordinates of the path points are converted into a rectangular plane coordinate system through Gaussian projection positive calculation; a driving path point and an operation path point are distinguished by utilizing spatial data clustering division to acquire agricultural machinery operation fields by utilizing a distance threshold, a scatter diagram is drawn for an agricultural machinery operation path in each agricultural machinery operation field, and a scatter diagram contour is calculated by applying a scatter diagram boundary extraction algorithm, and area calculation is made on a polygon formed by the outline of the scatter diagram of the operation field by adopting triangulation and numerical integration algorithms so as to obtain the area of each agricultural machinery operation field.

Description

technical field [0001] The invention relates to the technical field of measuring the working area of ​​agricultural machinery, in particular to a method for measuring the working area of ​​agricultural machinery based on path point analysis. Background technique [0002] In actual production, counting the area of ​​agricultural machinery operating fields can, on the one hand, provide farmland operation information for both sides of the agricultural machinery supply and demand side, avoid disputes between the two parties due to the operating area, and on the other hand, facilitate the supervision of agricultural machinery by relevant agricultural machinery supervision departments. Since the civilian use of GPS (Global Positioning System) technology, it has penetrated into many areas of the national economy and promoted the development of precision agricultural technology systems. Based on GPS technology, the operating position data of agricultural machinery can be obtained to...

Problems solved by technology

In recent years, there have been many studies on the judgment of agricultural machinery operation status and area measurement algorithms, but there are few studies on the identification of agricultural machinery operation areas, which have failed to solve the problem of agricultural machinery vehicle-mounted GPS recording and measurement areas, and are difficult to meet the actual needs of GPS agricultural machinery operation area measurement.
