摘要
测量不同生育阶段小麦冠层反射光谱,并使用傅立叶滤波及导数法信号处理技术对反射光谱进行处理,找出能最有效区分作物不同生育阶段的波长和波段,用这些波长和波段对应的反射率为指标,用模糊聚类(FCA)的方法对不同生育阶段小麦进行区分。
Measure canopies reflectance spectroscopy of wheat,using Fourier filtering and derivative to select wavelengths which can distinguish different developmental periods of wheat.Different developmental periods of wheat is distinguished by using fuzzy cluster analysis(FCA) with the reflectance rate of the selected wavelengths.
