摘要： 散斑互相关法是位移测试的一种光学方法，采集模型表面变形前后的散斑场,利用数字图像处理技术求出全场位移。通过可视化程序设计，操作者能够任意选择搜索区域、搜索窗口；能够控制输出点的间隔距离；实现像素与实际长度单位的转化；实现Y轴的反转；位移结果保存在dat文件中，可以方便打开；能够处理局部散斑场遭受破坏情况。

Abstract: The speckle correlation method is an optical method measuring the displacement. The initial and the deformed speckles of the model surface are taken，and the displacement can be obtained by the digital image process technology. The software is designed for the ease of operation throughout the visualization. The user can easily choose the target areas and different searching windows. The intervals of the output points can be easily adjusted. The graphical pixels can be converted into the actual length and the Y axis can be changed to opposite direction. Displacement results are preserved in text format, and documents can be easily opened.

Key words: Speckle Correlation Method, Software Design, Displacement Measurement, Image Proces
