| 摘 要： | 利用顾及敏感性分析的PROSAIL模型和植被指数模型,以青岛地区玉米作物为研究对象,对无人机多光谱影像的叶面积指数反演进行研究.反演结果显示顾及敏感性分析PROSAIL模型的R2为0.79,GNDVI植被指数反演结果的R2为0.82.实验表明利用无人机多光谱数据可进行玉米叶面积指数的反演,且效果较好.

| Abstract: | Taking corn in the Qingdao area as research object,we used PROSAIL model and vegetation index model to study the method of leaf area index inversion from UAV multi-spectral images.The inversion results show that R2of PROSAIL model is 0.79,and R2of GNDVI model is 0.82.The experiment shows that UAV multi-spectral images can be used to invert corn leaf area index,and the effect is good. |
