Technically, the DIC technique refers to a non-contact strain measurement method that mathematically compares the grey intensity changes of the images captured at two different states: before and after deformation. The measurement can be performed by numerically calculating the displacement of speckles which are deposited on the top of object’s surface. In this paper, the Two-Dimensional Digital Image Correlation (2D-DIC) is presented and its fundamental concepts are discussed. Next, the development of the 2D-DIC algorithms in the past 33 years is reviewed systematically. The improvement of 2DDIC algorithms is presented with respect to two distinct aspects: their computation efficiency and measurement accuracy. Furthermore, analysis of the 2D-DIC accuracy is included, followed by a review of the DIC applications for two-dimensional measurements.}, type={Artykuły / Articles}, title={A Review of Surface Deformation and Strain Measurement Using Two-Dimensional Digital Image Correlation}, URL={http://journals.pan.pl/Content/106333/PDF/10.15.15mms-2016-0028%20paper%2013.pdf}, doi={10.1515/mms-2016-0028}, keywords={surface deformation, strain measurement, two-dimensional digital image correlation}, }
