Abstract

The invention discloses a precision agriculture-oriented weighted spatial fuzzy clustering method and device. The method comprises the following steps that 1) according to data of various input indexes, weight coefficients of all the indexes are calculated by using the analytic hierarchy process so as to obtain a general goal weight matrix; 2) according to an input original data matrix, the general goal weight matrix is used for building fuzzy equivalent matrixes, and according to different classification threshold values, the fuzzy equivalent matrixes are classified so as to obtain dynamic clustering views; 3) by means of F-statistics, the optimal classification threshold value and the optimal number of categories are calculated, and the dynamic clustering views are classified so as to obtain dynamic clustering results.

Description

technical field [0001] The invention relates to information data processing technology, in particular to a precision agriculture-oriented weighted space fuzzy clustering method and equipment. Background technique [0002] Precision agriculture refers to a field management method based on variation. It is a system that implements a complete set of modern agricultural operation techniques and management in a fixed, fixed, and quantitative manner based on spatial variation supported by information technology. Precision agriculture is through the comprehensive application of GPS, RS, GIS and other technologies and automation technology, according to the specific conditions of each operating unit in the crop growth field, correspondingly adjust the input of materials such as seeds, chemical fertilizers, pesticides, etc., to reduce input, increase income, protect agro-ecological purposes. [0003] In the implementation process of precision agriculture, due to the adoption of "3S"...
