摘要
分析了相位解缠的原理及干涉条纹数据的特点 ,提出了一种基于中值自适应滤波、区域分割和编码的解缠方法。
This paper describes an unwrapping phase method based on region_segmentation and coding.The algorithm can easily unwrap noisy interferograms,but it will meet some problems when the phase contains aliasing.In addition,in order to perform the calculation easily when finishing region_segmentation,a method of encoding has been proposed.The main steps are:① Pretreatment with the medium and gradient_based adaptive filter in order that the segmentation can be carried out correctly;② The region_segmentation with the familiar algorithm;③ Encoding the regions from the previous step;④ Calculating the unwrapped phase by easy account. To verify the proposed algorithm,the algorithm has been tested with simulative data and actual data.
