通过对散斑特性的研究与分析，提出了一种快速、准确的散斑相关搜寻法。同时还提出一种“逐步更新"的测量方法，它克服了由于大的位移而导致相关系数偏低的缺点。实验证明，这种测量方法是一种快速、准确的大范围面内位移测量方法。

A rapid and accurate method of speckle correlation displacement measurement is presented based on study and analysis on speckle characteristics.A “progressive updating”method of large-scale displacement measurement is proposed to avoid the defect of low correlation coefficient caused by large-scale displacement.The experimental results prove the method is rapid and accurate for large-scale dynamic displacement measurement.
