| 摘 要： | 提出遥感信源色彩信号的提取及复现理论,给出了可操作的技术路线,设计了提取与复现程序,用MODIS(中等分辨率航天成像光谱仪)数据提取并复现了色彩信号,生成了色彩信号图像。未进行大气校正的色彩信号图像等效于太空对地摄影,从图像可看出,地物被笼罩在瑞利散射形成的蓝色“云雾”下。经瑞利散射纠正后的色彩信号图像接近于地面真彩色摄影,非专业人员能根据地物颜色及阴影判读出常见地物。理论可用于遥感信源地面真彩色图像重建、色彩信号不完整信源彩色仿真、航天对地真彩色摄影、信源质量评价。

| Abstract: | The theory of extraction and reapparition of color signal in remote sensing information source is provided, the operable technique route is given, the program of extraction and reapparition is designed, color signal has been extracted and reappeared through using MODIS (Moderate Resolution Imaging Spectroradiometer) data, and color signal images are maked. The color signal images which did not carry on correcting the atmosphere are equal to the space photographs to the ground, the ground objects are covered with blue mist which is formed by Rayleigh Scattering . The color signal images corrected by Rayleigh Scattering are close to true color photography in ground., laypeople can judge usual ground objects based on color and shadow of ground objects. In theory ,this can be used for reconstructing ground true color images of remote sensing information source, clearly imitating color of color signal of unintact information source , aerospace true color photograghs to the ground, and information quality evaluation. |
