| 摘 要： | 针对自主研制的星载法布里一珀罗干涉仪（Fabry—Perot Interferometer，FPI）样机，介绍了Fabry—Perot（F—P）的测风原理和风速反演算法，阐述了F—P测风干涉数据的自动化处理方法，包括干涉条纹图像滤波、分割、细化和特征数据的提取．滤波包括中值滤波和背景补偿，分割采用区域平均灰度值阈值法，借助数学形态学计算填充和消除二值化条纹的断裂点和毛刺．最后，按照骨架提取思想细化成干涉条纹线条，提取其特征数据．应用VC＋＋编程语言开发软件平台，对上述F—P测风仪数据自动化处理方法进行了验证，结果表明其可行性高、适应性强．

| Abstract: | Fabry-Perot Interferometer(FPI) is one of the best detectors to explore the middle and upper atmosphere wind.A spaceborne FPI prototype with a large diameter telescope was designed and constructed and the image of interference fringe was acquired.This paper introduces the principle of FPI and a feasible inversion algorithm of the wind velocity in the middle and upper atmosphere. A technique for F-P interference fringe auto-processing is developed.The technique includes filtering, segmentation,thinning,and e... |
