【摘要】 中国科学院空间中心自行设计搭建了带有大口径望远镜的星载FPI原理样机获取了干涉条纹图像。条纹图像滤波和分割自动化处理已经完成。条纹图像的细化对反演计算中高层大气风场信息的精度至关重要。深入探讨细化概念和细化算法,进行细化条纹滤波修整。采用VC++进行实现,应用效果明显,得到验证。最后,依据原理样机实际情况,探讨中高层大气风速的反演算法,说明其可行性。更多还原

【Abstract】 Center for Space Science and Application Research of CAS have designed and constructed a spaceborne FPI prototype with a large diameter telescope.As a consequence,image of interference fringe was acquired.Visual C++ was adopted to develop the FPI interference fringe image process software and filtering and segmentation algorithms were implemented.As thinning is essential for the accuracy of inverting middle and upper atmosphere wind,thinning is discussed in details.Moreover,thinning algorithms are negotiated,put into practice and compared.The stripe repairs and maintains are also needed and realized.All the auto-process methods mentioned above have a good experiment result in practice.At last,the feasible inversion principle and algorithm are also interpreted here.更多还原
