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.
