岩石材料基于天然散斑场的变形观测方法研究
DEFORMATION MEASUREMENT METHOD FOR ROCK MATERIALS BASED ON NATURAL SPECKLE PATTERN
【摘要】 许多类岩石材料由于其成分的原因在表面形成良好的散斑结构,用DSCM方法对这些岩石材料进行变形观测时可直接拍摄表面得到散斑图。基于这种天然散斑场的变形观测方法,进行了岩石材料变形的观测实验,验证了方法的可行性和优越性。
【Abstract】 Many kinds of rock materials bear random speckle pattern on their surface due to the componential reason. This speckle structure can be captured and saved as speckle images for DSCM method when doing deformation measurement. DSCM method based on the natural speckle pattern is studied. Some rock material experiments are completed and the results of experiments prove the feasibility and advantage of the method.
