| 摘 要： | 研究了面向土地沙化的基于波段组合的遥感图像彩色合成问题。通过计算陆地卫星TM(Thematicmapper,TM)数据波段间的协方差、相关系数矩阵和主要统计特征参量,获取TM波段组合的基础数据;然后采用信息量分析法确定土地沙化研究的优劣波段,通过波段间的相关性分析筛选适合于土地沙化分析的波段集,基于该波段集,采用最佳指数法给出优化波段组合,在优化波段组合与彩色图像合成基础上进行遥感图像预处理。以河北省沽源县的TM数据为例,对河北省沽源县TM各波段及监督分类中沙化样本各波段信息进行了处理,结果表明TM4、7、1为该区域土地沙化研究的最佳波段组合。

| Abstract: | Color composition of remote sensing image based on spectral combination for land desertification is studied. Basic data is given via calculating covariance,correlative coefficient and main statistical parameters between different bands.Optimal spectral combination is given by exponential method based on spectral sets derived from analysis of correlation and information quantity.Remote sensing image are determined by the optimal spectral combination.Image enhancement of remote sensing is developed through the optimal spectral combination and color composition,too.Results derived from processing of TM spectra and spectral information of land desertification samples in supervised classification for Guyuan county,indicate that the spectral combination,TM4,7,1 is the optimal spectral combination. |
