摘要
针对传统接触式应变测量的局限性,探讨了基于数字图像处理技术的非接触式应变测量方法——数字散斑相关方法(Digital Speckles Correlation Method,DSCM),并用单向拉伸实验对该方法进行了验证,结果表明,该方法是一种实用快速、高精度的变形测量方法。
To solve the limitations of traditional contact strain measurement, a non-contact measurement method called Digital Speckle Correlation Method （DSCM） based on digital image processing is introduced, and simple extension test is provided to verify the reliability of DSCM. Experimental results show that this method is a fast,precise way for displacement and strain measurements.
