A Novel Framework for the Dynamic Characterization of Civil Structures Using 3D Terrestrial Laser Sructures of interest need to be accessed for instrumentation, which is not always feasible due to complex site conditions; (2) the reliability of the results is highly dependent on the locations and the limited number of sensors mounted on the structure. To overcome these challenges, there is a crit

Full-field approaches that make use of direct methods such as optical flow have the added attractive quality that they have demonstrated an ability to detect small damage on account of the high spatial density of pixels associated with imager measurements. For the case of

Video-based SHM techniques are advantageous due to the lower installation/maintenance costs, analysis in high-spatial resolution, and its non-contact monitoring features. Both digital

Dynamic Mode Decomposition for Resonant Frequency Identification of Oscillating Structures,as edges, are prime candidates for motion estimation; however, their rapid motion can pose problems for computer vision techniques. Most vibration seen in video is unperceivable to the naked eye, which can make sub-pixel displacement extraction more complex. Phase-based motion magnification (PMM) is
