Abstract

Digital image correlation (DIC), also known as particle image velocimetry (PIV), has become a well-established approach for the calculation of field displacements in geotechnical engineering. However, commercial and opensource DIC/PIV software is often used without full realisation of the implications of various parameters on accuracy and efficiency. In this paper, a critical evaluation of the various methods and components of DIC relevant to geotechnical applications is presented. In addition, new algorithms are presented to address some specific problems encountered when using DIC techniques in geotechnical research. Examples and comparisons are presented to support the proposed guidelines, and thus demonstrate the effectiveness of the newly developed techniques.
