Parcel area calculating method based on line path

Abstract

The invention discloses a method for calculating the land area based on a line path. Firstly, the target land is determined, and a GPS terminal is installed on the agricultural machine for operation, and the latitude and longitude data are collected in real time during operation, and the latitude and longitude coordinates are GPS point data in rows or columns The form is distributed on the plot of work; then, arrange the GPS point data in time order to form a continuous or discontinuous line path, based on the line path, expand a certain radius along the two sides of the line path to form The polygon becomes the buffer zone; the sector search method is used to optimize the endpoints of the line path to form a buffer area along the endpoint; the convex arc method is used to optimize the buffer area of ​​the polyline part of the line path to form the final line path polyline Part of the optimized buffer zone; finally, the area of ​​the optimized buffer zone is calculated by the vector triangle accumulation method to obtain the final area of ​​the polyhedral plot.

Description

technical field [0001] The invention belongs to the technical field of intelligent agriculture, and in particular relates to a calculation method for plot area based on a line path. Background technique [0002] Agricultural users often need to count the land area as a basis for billing or other statistical considerations; due to the complexity of the terrain of agricultural operations, the area of ​​many land plots cannot be calculated accurately, resulting in the inability to obtain the relevant interests of farmers and government departments. Statistically accurate land area affects decision-making and management. [0003] The existing plot calculation methods are generally estimation method and GPS measurement method, and the traditional estimation method obviously cannot meet the requirements of modern agriculture for accurate acquisition of plot area data; and the GPS measurement method, due to the irregularity of the terrain and the use of When harvesting agricultura...

[0002] Agricultural users often need to make statistics on the area of ​​plots as a basis for billing or other statistical considerations; due to the complexity of the terrain of agricultural operations, the area of ​​many plots cannot be calculated accurately, resulting in the inability to obtain the relevant benefits of farmers and government departments. Statistically accurate land area affects decision-making and management

[0003] The existing plot calculation methods are generally estimation method and GPS measurement method, and the traditional estimation method obviously cannot meet the requirements of modern agriculture for accurate acquisition of plot area data; and the GPS measurement method, due to the irregularity of the terrain and the use of When harvesting agricultural machinery obtains GPS measurement points, the track of the harvester is a Z-shaped circular harvest, or a back-shaped circular harvest. This track is different from the measurement method of the conventional acre meter. The GPS points used can easily cause calculation confusion or double calculation, resulting in a large error between the measured area and the actual area
