Abstract

Digital image correlation is used for the deflection measurement of a simple beam model in this study. The deflection distributions are obtained from images that are recorded using a digital camera with a shift lens. The experimental results show that the use of a shift lens is effective for the case of situations where direct view of the object is obscured. In addition, it is found that the deflection distribution of the relatively large structures can be measured using digital image correlation even if the random pattern is not painted on the object surface. The deflection measurement of bridges using digital image correlation for safety inspection is expected in the near future.
