Nowadays, non-contact measurement systems have found application in the Structural Health Monitoring of civil engineering structures for the detection, localization and assessment of damage. In the field of static deflection measurement, the vision based techniques have become more popular. The deflection curve obtained by image processing and analysis methods can be analyzed in order to detect and localize the change of the curvature, which implies the appearance of a crack. In this paper, the vision based deflection measurement system is discussed. The deflection of beam-like structures is computed by means of digital image correlation. The damage detection and localization is based on the irregularity detection by means of analyzing the deflection curve. A new approach and some selected methods for damage detection and localization will be highlighted and their results obtained in the laboratory setup will be presented and discussed.
