摘　　要：根据数字散斑相关理论及计算机视觉理论，提出物体大变位时散斑场的相关性恢复方法，以寻求在大变位情形下从图象数据中提取变形量的途径。文中通过讨论数字散斑相关方法，物体刚体位移的确定方法，引入相关性恢复的概念，并对其精度与实际应用方面作了探讨，最后给出了实例数据。ased on speckle digital interrelation (SDI) method and computer vision theory,thispaper proposes the principle of resuming correlation of the speckle field images to measure defotmation when an object's position is changed. After the SDI some methods in computer vision areintroduced, the concept of resuming the correlation is presented,and its precision and applicationare discussed. The data of an example is given in the end.
