抄録

We investigated a method to measure displacement disiribution in the full view field of a CCD camera using digital image correlation (DIC) technique. This method intends to measure displacement field on a surface by comparing two images before and after deformation taken with a CCD camera. In this method, accuracy of the search of corresponding points on the two images influences largely on the accuracy of the measured result. This method takes time to calculate template matching with high accuracy at many observing points. In this paper, we investigated a template matching with high efficiency and also used a parallel processing using multi-core CPUs. The result shows that parallel processing is very effective for template matching in the DIC techmque.
