油菜氮素的高光谱特征补偿和组合模型研究
Analysis for High - spectral Features Compensation and Composite Pattern of Rape Nitrogen
摘要
Abstract
[Objective] The aim of this research was to explore the decoupling method of interaction of water and nitrogen on the spectral analysis of rape nitrogen. [Method] The analysis method of reflectance features compensation and composite pattern was put forward,which can compen-sate nitrogen detection influenced by water factor. And the spectral analysis models for nitrogen content were respectively established. [Result] The results showed that the correlation coefficient (A) of nitrogen diagnosis modets corrected by above-mentioned method was 0.89 and 0.91, and the root mean square error (RMSE) was 2.94 and 1.47. [Conclusion] The interaction of water and nitrogen can be effectively decoupled by the analysis method of composite pattern,which was preferable to the quantitative analysis of rape nitrogen.关键词
