This study deals with the visualization of deformation during wood drying by Digital Image Correlation method using an Optical Measurement System. By this measurement, localized deformation by drying stress can be observed in naked eye. Estimation of displacement maps of willow tree disks and Oregon oak planks provided the strain distribution during drying of wood. And the stress concentration in the Oregon oak plank was successfully visualized. It is considered that the use of a DIC system in wood drying can more accurately visualize strain changes of wood surface and using of DIC may provide more appropriate drying schedule preparation for unknown species or refractory wood species.
