| 摘 要： | 文章简要介绍了航天清华一号 (HT - 1)微小卫星及其图像质量状况 ,并以HT - 1扬州景图像为例 ,用ENVI软件对图像进行噪声消除、波段间错位纠正与假彩色合成、地面分辨率求算 ,探讨了其在国土资源调查中的应用。结果表明 :HT - 1图像信息量丰富 ,但噪声明显 ,可通过中值滤波基本消除 ;各波段图像间像元错位较大 ,仍可以通过波段配准来消除 ;地面分辨率为 :4 1 6 989m ,基本达到了设计的要求 ;能满足中比例尺的国土资源调查领域的应用要求

| Abstract: | In this paper, the quality of the image of HT-1 Micro-Satellite was analyzed. For instance, the image in Yangzhou area was processed by noise removal, geometric correction and artificial color composing etc. And the important indexes of the image quality such as image resolving, the quantity of information, and the application in the survey of land resource were analyzed. The result shows:The image of HT-1 has much information and much noise which can be removed by median filter. The same site on the image of each band is mis-located but it can be corrected. The size of image resolving is 41.6989 meters which are amount to the design objection. The image of HT-1can be applied in the survey of land resource by median scale. |
