| 摘 要： | 利用自主研发的面阵扫描成像光谱仪Pushbroom Imaging Spectrometer(PIS112)对冬小麦不同生育期的长势进行监测,获取了冬小麦关键生育期图谱合一的光谱影像。通过对获取的高光谱数据进行分析,对单叶氮素含量、水分含量和叶绿素含量进行了初步的建模探索。研究结果表明:叶色值(SPAD)、叶片含水量和叶片含氮量的相关系数均在0.9以上。因成像高光谱具有图谱合一的特性,所以为利用航天和航空影像大面积监测作物长势和品质、防控病虫害发生,研究作物精细信息提供了又一有利手段。

| Abstract: | Using the self-development line-array Pushbroom Imaging Spectrometer（PIS112）to monitor winter wheat growth information in different growth periods,we obtained the wheat combination images with spectrum in the key period.Through analyzing hyperspectral data,the nitrogen content,moisture content,chlorophyll content and single leaf spectral value were studied by modeling.Results showed that the correlation coefficients of SPAD,moisture content, and nitrogen content are more than 0.9.With the integration of leaf spectrum and clear images,the Pushbroom Imaging Spectrometer provides a powerful means for using spatial and aerial images to monitor large-scale crop growth and quality and to control pests and diseases,as well as to research crop precise information. |
