摘　　要：云纹法是一种重要的实验应力分析方法,在科学研究和工程中的应用变得越来越成熟和广泛。实验直接得到的是一些模糊的较粗的条纹,而计算所需要的是条纹的中心线。以前很多时候需要自己动手编程来处理图像,所用的语言有C、C++、VB等,语句一般很长,很容易出现语法错误,研究者把大部分时间都用在编程上。因此寻找一种方便、快捷的方法来处理云纹图像是很有必要的。而MATLAB强大的图像处理功能无疑是较好的选择。本文利用MATLAB对实验得到的云纹图像进行处理,如图像的剪切、噪声处理、二值化以及细化处理等,最终提取云纹的中心线。The Moire method is an important experimental stress analytical method which application has become more and more mature and widespread in scientific research and engineering application. We often obtain Moire of blur as well as coarseness. Actually we need the central line of Moire to calculate the displacement and stress, Before people need to program with software C＋, C＋＋ and VB by themselves to process images. Because of long sentences, mistakes are easily made. So many researches had to spend many time on programming. So a method which is convenience and shortcut to process the Moire image need to be found. Out of question MATLAB with strong image processing function is a good choice. In this paper, MATLAB is used to process the Moire image obtained from experiment, such as image＇s shearing, noise processing, binary image and thinning process, finally the central line of Moire is extracted.
