Abstract

We propose a standardization effort on digital-image correlation, to collect and document the available methods for assessing image quality, for analyzing the images to derive displacement and strain values, and for determining the measurement uncertainties. These quantitative measurement methods are needed too guide the practitioners in decisions regarding specimen surface treatment, apparatus and procedures for acquiring images, analysis methods, and presentation of results. The purpose of this presentation is to notify researchers and practitioners in the field of this standardization effort and to invite participation. This presentation also briefly describes the scope of this standardization effort factors affecting image quality, digital-image correlation, evaluation of results derived from digital-image correlation procedures, and reporting suggestions.
