| Abstract | Deformation checking is an important procedure for measuring the structural health of complete civil engineering structures. Most classical methods for measuring deformation or deflection taking place in structures need periodic access for the particular area being monitored properly. Like remote sensing techniques, photogrammetry does not need any connection with the objects of interest, and this can be a great benefit when it comes to the deformation monitoring of inaccessible structures or simply large structures. This paper shows a cost-effective setup of digital cameras used for photogrammetry for calculating deformation monitoring of structural materials. The setup was tested in two experiments, in which concrete beams were deformed at different loading conditions by a hydraulic actuator. The methodology necessary to measure the deflections or deformations consisted of: (1) Image processing and extraction of co-ordinates. (2) Measurement of deflection and comparison by terrestrial methods. |
