| 摘 要： | 利用光谱微分分析方法,对原始光谱数据进行处理,分析不同等级盐渍土的光谱一阶微分曲线图和二阶微分曲线图。然后,与原始光谱进行对比,提取其中差异比较大的波段。最后,用欧式距离的方法对所选的特征波段进行盐渍土分类检验。检验结果表明,选择的特征波段能有效地区分不同的盐渍土等级。 |
| 关 键 词： | 盐渍土 高光谱 光谱微分 欧氏距离 |

| Abstract: | The original spectral data were dealt with the method of spectrum differential analysis,and the first derivative reflectance graph and the second derivative reflectance graph of different grades of saline soils were analyzed.Then the wave band which was the most different from the original spectrum was extracted.At last,the Euclidean distance method was used for the saline soil classification,which was conducted by using the selected characteristic wave band.The testing results showed that the selected char... |
