Method for performing statistics of agricultural machinery working area based on geometric mode

Abstract

The invention provides a method for performing statistics of agricultural machinery working area based on a geometric mode. The method comprises the steps that positioning point data uploaded by the agricultural machinery are filtered, and the points reserved after filtering are connected in turn so as to form multiple continuous straight line segments; a quadrangle is formed by each line segment of the multiple simplified continuous line segments according to the working width W of the agricultural machinery, the two opposite sides a and b of each quadrangle are parallel to the corresponding line segment, and the sides of the quadrangle of the start point and the end point of the reserved points are respectively perpendicular to the line segment formed by the start point and the second point and the line segment formed by the end point and the penultimate point; logical operation is performed on the acquired multiple quadrangles so as to acquire a quadrangle n; and the area Sn of the quadrangle n is calculated. Statistics of the agricultural machinery working area is performed by the geometric mode so that the problem of low accuracy caused by excessively large message in the mesh mode and the problems of high number and complicated calculation caused by excessively small mesh can be avoided, and the calculation time and the memory space can be saved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for counting the working area of ​​agricultural machinery based on a geometric method. Background technique [0002] At present, the proportion of automation in agricultural work is getting higher and higher, and there are more and more kinds of agricultural machinery. When the agricultural machinery is working in the field, the land it really works on is the most concerned content of farmers, such as whether If there is a leak on the floor, it will have a great impact on the work. Because the width covered by the agricultural machinery is fixed, the actual working area of ​​the agricultural machinery can be calculated in principle based on the track traveled by the agricultural machinery. Some existing calculation methods are based on the grid method, that is, the field is divided into grids of 1 meter or several meters square, and when the agricultural machinery...

Problems solved by technology

Because the accuracy of the gridded statistical method depends entirely on the accuracy of the grid, if the grid is too large, the accuracy requirement cannot be met; if the grid is too small, the accuracy can be guaranteed, but the number of grids will increase in series. The way of growth, it seems powerless to deal with such a large amount of data on ordinary portable devices
