摘要
基于相关理论,提出了一种非接触式测量面内位移的数字标记点识别方法.该方法能应用于物体变形前后标记点的识别.相对于其它光学测量方法而言,该技术实验过程简单,能够应用于小变形、大变形等不同的变形范围.本文还将这一方法应用于高分子薄膜材料的时间特性实验测试,结果表明,此方法可有效用于柔度较大材料的变形测量.
A marker recognition method, which can be used to recognize a digital marker before and after deformation, is presented. The experiment procedure is simplified and the application field is broadened. This method is also used to test the time dependence behavior of macromolecule film material. Results show that the method can be efficiently used to measure larger deformation of material.
