摘　　要：干涉条纹分析是光学干涉计量的重要分析方法,本文提出基于改进Yangtagai求极值点法与改进Hilditch细化法相结合的干涉条纹中心线提取与细化方法,该方法具有条纹断点少、抗噪声能力强以及处理速度快的特点。通过实验证实了本文提出方法的有效性。Interferometric fringe analyzing is an important processing method in optical interference measurement. In this paper, a new method based on modified Yangtagai extremum extracting algorithm and modified Hilditch thinning algorithm is proposed for fringe skeletonizing and thinning. It has the characteristics of little breaking, little impacted by noise and processing fast. The experiments show the proposed method is efficient.
