本研究开发了一种新型的基于图像分析的非接触式结构构件变形测量系统。对几个材料试件进行了加载试验，以验证所提出的测量系统的有效性。试验测量结果的比较表明，虽然该系统存在测量精度问题，但非接触式测量系统与常规式测量方法的测量结果基本吻合。测量结果表明，该测量系统具有测量构件大变形的潜力。

In this study, a new non-contact type measurement system using image analysis for the deformation of structural members is developed. Loading tests of several material specimens are conducted to confirm the validity of the proposed measurement system. The comparisons of test measuring results show that although the proposed system has left a number of problems of measuring precision, the measuring results of both a non-contact type measurement system and usual type measurement method corresponded mostly well. Furthermore, the measuring results show that the proposed measurement system has the potential of measuring large deformations of structural members.
