摘要:
利用高光谱参数预测烤烟叶片中的烟碱含量,选取大田试验条件下不同光照强度处理的烟株测定光谱反射率。选择18个高光谱参数与烟碱含量进行相关性分析并构建回归方程,进而建立烤烟叶片烟碱含量的高光谱参数预测模型,并对模型进行均方根误差和相对误差检验。结果表明:烟碱含量与选取的高光谱参数之间的相关系数均达到极显著水平,最高为0.83。选取其中相关性最好的8个高光谱参数并建立多种函数的回归模型发现,抛物线的拟合精度r2在各方程中为最优,达到0.773。结合误差检验得出:选取的8个参数中误差检验与预测模型的精度相符合,说明预测模型稳定性良好,能够进行烟碱含量的快速、简便、准确的预测,尤其以NDSI导数、RSI导数、SASI导数的抛物线预测模型为最佳。
