摘要
数字散斑相关方法(DSCM)是一种全场、无接触、高自动化和高精度的光学变形测量方法,与其它变形测量技术相比数字散斑相关方法有其独到的优越性能。经各研究学者不断的研究改进,数字散斑相关方法的理论逐渐完善,作为一种固体材料表面变形测量方法,在固体力学的实验中广泛应用,同时在土木工程变形测量中得到较快的发展。本文对该方法的基本原理、模型及决定测量精度的因素进行了简单介绍,同时对其在土木工程中的应用进行了概述。
As a non-contact,high automation and high precision optical deformation measurement method,Digital speckle correlation method（DSCM）is more outstanding than convention deformation measuring technology. After constantly improvement, the theory is becoming increasing sophisticated.As a solid material surface deformation measurement method,DSCM was widely used in solid mechanics experiment,and gets quickly development in the civil engineering deformation measurement.DSCM and its applications in civil engineering are illustrated in this article.
