Computer vision methods using digital image correlation for image matching, with emphasis on stereovision systems for three-dimensional shape and displacement measurements, are described. Basic theoretical developments and details regarding a recent application of the methodology to quantify deformations in structural components are presented. Results indicate that vision-based methods can be used successfully to quantify shape and deformation in a wide range of structural and component configurations.
