Analysis of the Error in Measurements Obtained Using Digital-image Correlation Method with a New Displacement Mold in Subset

本文对数字图象相关测量方法的测量误差进行了系统的理论分析和实验研究 ,分析了各项测量误差的产生原因及实验现象 。

All measuring errors of digital image correlation method (DICM) and their origins were analyzed theoretically in detail and the relevant experimental studies were carried out. Some methods to eliminate these errors are proposed.
