摘要
文章在简要介绍遥感器在轨MTF评测值在遥感图像处理中的意义基础上,分析了中分辨率遥感卫星成像过程MTF在轨测试的各种方法的适用性、算法和具体指标要求,提出了适合于中分辨率遥感卫星成像过程MTF的在轨评价方法,并剖析了遥感卫星成像过程中影响MTF的多种因素;最终以CBERS-02星CCD图像为对象进行了试验,并有效运用于图像恢复。
In the paper,the importance of in - flight MTF estimation value in the field of image processing is firstly introduced. And then several estimation methods and their character, applicability, arithmetic and their specific indexes are analyzed. Based on that, the most easily - operated methods are presented. Subsequently we use the image of CBERS - 02 CCD as the test object, and deduce several influence factors. Lastly, we try using the test result for image restoration and get image with more detailed information.
