Presentation title: Evaluation of random patterns using frequency analysis for digital image correlation method
Content: The digital image correlation method is an image-based measurement technique used to measure the deformation of an object. Although it is known that the random patterns applied to an object’s surface have a significant impact on measurement accuracy, a method for pre-evaluating this effect has yet to be established. This research proposes a method for predicting measurement accuracy in the digital image correlation method using information obtained from the fast Fourier transform of random pattern images.
