METHOD FOR STANDARDIZING AND GENERATING SPECKLE PATTERN IN DIGITAL IMAGE CORRELATION FOR MONITORING OF DEFORMATION/STRAIN DURING EXPERIMENTAL INVESTIGATION.

摘要

The present invention discloses a method for generating speckle pattern on surface of an object comprising measuring the object size and corresponding required size in pixels of image of the object, generating a simulated speckle image pattern based on analytic dependency between total number of speckle to be in the image, random peak intensity of each speckle at random position and size of the speckle, providing the simulated speckle image pattern onto a pattern impression transferable medium and then transferring the speckle image pattern form the pattern impression transferable medium to the object surface by placing the pattern impression transferable medium on the object surface to make a bonding between the speckle image pattern applied to said object surface.
