Digital image correlation for structural measurements

Proceedings of the Institution of Civil Engineers - Civil Engineering, 2012
Digital image correlation is an optical imaging technique that compares images taken of a structure and is well established for laboratory measurements. By processing pairs of images under different loading conditions, the full-field deformation of the structure can be measured.

Augmented Lagrangian Digital Image Correlation

Experimental Mechanics, 2018
Digital image correlation (DIC) is a powerful experimental technique for measuring full-field displacement and strain. The basic idea of the method is to compare images of an object decorated with a speckle pattern before and after deformation, and thereby to compute the displacement and strain fields.

Recent Progress in Digital Image Correlation

Experimental Mechanics, 2010
In this paper, we report the following important progress recently made in the basic theory and implementation of digital image correlation (DIC) for deformation and shape measurement. First, we answer a basic but confusing question to the users of DIC: what is a good speckle pattern for DIC?

Digital Image Correlation and Color Cameras

Experimental Mechanics, 2017
Digital Image Correlation (DIC) is a well-known experimental technique. It works by constructing a (surjective) mapping of pixel intensity from reference to target image, where the mapping parameters are identified using a Least Squares approach.

Digital Image Correlation

\textbf{La Corrélation d’Images Numériques (CIN)} est une technique de mesure optique permettant de capturer des champs de déplacement d’un matériau, d’un composant ou d’une structure soumis à une sollicitation. Développée au début des années 1980 \cite{sutton83}, la méthode visait initialement la mesure de champs de déplacement 2D sur des objets plans
