Abstract

Digital Image Correlation (DIC) is a widely used image based technique for measurements of displacements, strains and shape of different kind of objects. The method was at first used in the field of experimental mechanics, but features of the method, such as full-field, non-contact measurement, 3D data or scalable accuracy, attract the attention of industry. However, the scale of industrial installations as well as requirements connected with DIC setup and object preparation hinder adaptation of DIC to industrial practice. In the paper we present DIC technique designed for mobile devices, that enables DIC measurements with cameras that are built-in the smartphones, tablets or smart cameras. The application provides instant access to deformation and shape measurement results for non-qualified staff in industries. In order to attune functionality to industrial requirements, the mobile version of DIC integrates procedures for merging of DIC data distributed in time and a single-camera 3D shape measurement technique. The simplified measurement process as well as initial accuracy assessment are discussed in the paper.
