摘要

条纹中心线法是一种重要的电子散斑干涉条纹解调方法, 其前提条件是获得高准确度的条纹中心线.本文在分析载波电子散斑干涉条纹自身特征的基础上, 提出了一种基于载波条纹调制方向提取条纹中心线的方法.该方法首先通过同态滤波有效滤除高频乘性散斑噪音, 提取出载波条纹;然后应用基于调制方向提取中心线算法确定载波条纹灰度极值点并做二值化处理;再采用基于中心线拟合或者基于条纹间距的边沿中心线补偿法, 获得完整的条纹中心线图.实验结果表明:该方法简单、可靠, 能快速、准确地提取出连续的中心线.

Abstract

Fringe center method is an important demodulation method for electronic speckle pattern interferometry fringe. The precondition of this method is to obtain fringe skeletons with high precision. Based on the analysis of carrierwave electronic interferometry fringe characteristics, a fringe skeletons extracting method based on modulation direction was proposed. Firstly, a homomorphic filtering was used to filter the high frequency multiplicative speckle pattern noise effectively and pick out carrierwave fringes. Then a fringe skeletons extracting algorithm based on modulation direction was applied to confirm the dots of gray scale extremum and make binarization processing. In order to get whole fringe skeletons map, the mending methods based on skeletons curve fitting or based on the fringe separation were adopted to compensate the edge fringe skeletons. Experimental results show that this method is simple and reliable. It can extract the consecutive fringe skeletons quickly and accurately.
