摘要
本文基于无人机高光谱技术,对松材线虫病的高效、准确监测进行了研究。以山东省威海市河东村为试验区域进行了高光谱数据采集,分析了松树不同染病时期的光谱曲线,并基于此提取了松材线虫病疑似树木。通过对提取结果进行实地检核,发现利用高光谱技术进行松材线虫病疫木提取的精度可达90%,说明利用无人机高光谱技术进行松材线虫病监测是可行的。
The efficient and accurate monitoring of pine wood nematode disease was studied in this paper based on UAV hyperspectral technology.The hyperspectral data were collected in Hedong Village,Weihai City,Shandong Province,the spectral curves of pine in different infection periods were analyzed,and the suspected trees with pine wood nematode disease were extracted.It is concluded that the extrac⁃tion accuracy of pine wood nematode diseased wood by hyperspectral technology can be up to 90%from the field inspection,which verified the feasibility of using UAV hyperspectral technology to monitor pine wood nematode disease.
