摘要
近年来,随着信息技术的迅猛发展,高光谱遥感作为一种快速监测手段已经被广泛应用于农业病虫害监测中,高光谱遥感在农业中主要的应用领域之一。通过分析近5年来高光谱技术在农作物病虫害研究情况,阐述了应用高光谱遥感技术进行农作物病虫害监测的原理,主要从原始光谱的导数变换及对数变换、光谱位置和面积的特征参数提取、光谱吸收特征参数提取、基于连续同去除的特征参数提取4种方法回顾了国内外应用高光谱进行农作物病虫害监测的研究进展,在此基础上,总结了高光谱遥感技术应用于农作物病虫害监测亟待解决的问题及相应的解决途径。
With the advances in electronic and information technologies,Hyperspectral remote sensing have been developed for crop diseases and pest detecting around the world. Hyperspectral remote sensing for crop diseases and pest detection included two aspects which were canopy spectral detection and Hyperspeetral image. This paper describes the principle of the application of hyperspectral in monitoring crop diseases and pest in detail, then summarizes the research progresses at home and abroad area ,including spectral derivation, feature parameter extraction based on spectral areas and wavelengths＇ position, spectral absorption feature parameters extraction, and feature parameter extraction based on continuum removal four aspects.At the end, some of the problems and solutions on the use of hyperspectral remote sensing for crop diseases and pest dectecting are also discussed .
