“…Accordingly, the past two decades have resulted in the development of a number of DIC techniques in order to improve on this sub-pixel accuracy. Some DIC algorithms rely on the intensity interpolation [6][7][8], others on Newton-Raphson iteration [9,10], curve-fitting or interpolation of the correlation coefficients [11,12], optical flow method [13,14], complex spectrum [15], genetic and neural network methods [16,17] or the center of mass estimation of the correlation peak [3].…”

“…In 2009, Paepegem et al [31] further optimized the peak-finding approach in their study on the deformation characteristics of window security film. In their work, the centre of mass of the correlation peak was calculated and then the local deformation with the sub-pixel accuracy was determined.…”

Among the full-field optical measurement methods, the Digital Image Correlation (DIC) is one of the techniques which has been given particular attention. 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 2D-DIC 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.

“…As an optical-numerical full-field measurement method, digital image correlation (DIC) has proven to be an ideal tool for a wide range of applications, including the identification of the mechanical material behavior through inverse modeling (Cooreman et al 2007(Cooreman et al , 2008, structural health monitoring (Sas et al 2012) and the study of the deformation characteristics of a wide range of materials (Ivanov et al 2009;Van Paepegem et al 2009;Srikar et al 2016). During the testing of specimens B103-B109, the stereo-vision digital image correlation technique (3D-DIC) has been adopted to assess the displacements and deformations during the loading procedure.…”

This paper investigates on the use of advanced optical measurement methods, i.e. 3D coordinate measurement machines (3D CMM) and stereo-vision digital image correlation (3D DIC), for the mechanical analysis of shear deficient prestressed concrete members. Firstly, the experimental program is elaborated. Secondly, the working principle, experimental setup and corresponding accuracy and precision of the considered optical measurement techniques are reported. A novel way to apply synthesised strain sensor patterns for DIC is introduced. Thirdly, the experimental results are reported and an analysis is made of the structural behaviour based on the gathered experimental data. Both techniques yielded useful and complete data in comparison to traditional mechanical measurement techniques and allowed for the assessment of the mechanical behaviour of the reported test specimens. The identified structural behaviour presented in this paper can be used to optimize design procedure for shear-critical structural concrete members.
