摘要：

A multi-camera Digital Image Correlation (DIC) systems have been developed to match the specific requirements for measurements posed by building and petrochemical industries. The two most important issues are connected with considerable dimensions of objects and a time line of the measurements. Although DIC provides capabilities of scaling a field-of-view (FOV), dimensions of industrial installations in many cases are too big to be measured with DIC based on a single camera pair. In this paper we present two strategies that can be used for spatial stitching of the data obtained with multi-camera DIC systems, namely a strategy for the case when there are overlapping FOVs of 3D DIC setups and a strategy for the case when 3D DIC setups are distributed and not necessarily have overlapping FOVs. Two practical applications of the multi-camera DIC system are described in order to show its feasibility in industry. (C) 2015 Published by Elsevier Ltd.
