摘　　要：本文提出根据白光散斑图像数据模拟刚体位移复位的相关性恢复方法。Based on the speckle digital interrelation (SDI) method and computer vision theory,the principle of resuming correlation in the speckle field images is proposed to measure defovmation of displaced object.After the SDI and some methods in computer vision are introduced,the concept about correlation resuming is presented,and its precision and application are discussed.An example is given at the end.
