摘要
为对作物进行田间数量化管理以及长势监测,从数字图像监测作物长势的基本原理、数字图像获取方法、图像分析处理技术以及数字图像在作物长势监测方面的应用4个方面进行概述,简要归纳了数字图像基本原理、获取及分析方法,总结出可以利用数字图像实现作物覆盖度、叶面积指数、生物量、氮素营养诊断进行监测,认为对于数字图像的获取应明确获取标准,要根据具体情况选取分析方法,同时在今后可以利用专家模型,多角度评判作物长势,以期为实现作物的精确管理提供参考。
In order to carry out the quantitative management and the growth monitoring of the crop in field,this paper discussed the methods of digital image acquisition,digital image analysis and processing,and digital image crop growth index monitoring,summarized the basic principles,the acquisition and method of digital image,and concluded that the digital image could be used to monitor the crop coverage,leaf area index,biomass and nitrogen nutrition.It is suggested that the acquisition standard of digital image should be clear,the analysis method should be selected according to the specific situation,and at the same time,expert system should be used to evaluate crop growth from multiple perspectives in the future,so as to achieve the precise management of the crops.
