无人机多光谱遥感对棉花化学打顶的生物量监测研究
Research on biomass monitoring of cotton chemical topping using UAV multispectral remote sensing
摘要
Abstract
Changes in the biomass of cotton fields after being sprayed with chemical topping agents of different concentrations by UAV were monitored using UAV multispectral images.Key indicators such as the optimal bands,band combinations,and vegetation indices for identifying cotton fields after topping were screened out.A variety of classification models were used to classify two types of images:those based on original images and those based on comprehensive images.The results showed that the maximum likelihood classification model achieved the best performance,with an overall classification accuracy of 84.54%and a Kappa coefficient of 81.73%.UAV multispectral images can monitor changes in cotton biomass after the application of chemical topping agents of different concentrations via UAV and accurately classify the biomass,providing theoretical guidance for the precise evaluation of cotton growth and development after the application of chemical topping agents.关键词
