摘　　要：针对环境一号卫星(HJ-1)CCD数据缨帽变换参数的提取问题,提出了传统的缨帽参数提取方法与光谱分析技术、施密特正交化算法相结合的HJ-1CCD数据的缨帽变换参数提取算法,利用该方法对山西省全区2009-2013年间处于植被生长季节的HJ-1CCD数据进行实验验证。结果表明,利用提取得到的缨帽参数对研究区的上述数据进行缨帽变换处理后,图像特征得到显著增强,亮度分量、绿度分量以及湿度分量对于地表特征的表达更为合理与清晰。该方法为区域条件下地表特征的识别与表达提供有效的技术途径。On the basis of traditional method of extraction of Tasselled Cap transformation parameters,this research put forward the extraction of Tasselled Cap transformation parameters for HJ-1A/B CCD data by combining the technology of spectral analysis based on category and the means of Schmidt orthogonalization.This method was used to extract the Tasselled Cap transformation parameters and verify the accuracy of the HJ-1CCD date during the vegetation growing season from 2009-2013 in Shanxi.The results show that after transforming the study area of HJ-1A/B CCD data with the Tasselled Cap transformation parameters,the feature of the image has been significantly enhanced,and the luminance component,greenness component and humidity component for expression of the surface characteristics are more reasonable and clearer.The extracted information has no much difference between the south and the north,so its Tasselled Cap transformation parameters can apply to the whole Shanxi Province during the vegetation growing season.It provides an effective way to identify and express the surface features in the regional conditions.
