Summary:Dynamic testing of large infrastructure has been an active research topic in the field of vibration measurement. The use of cameras has proven to be instrumental in active structural health monitoring (SHM) due to the cumbersome task of hand instrumenting structures. Although these approaches are non-invasive, some methods require: a large amount of data collection, structure preparation, and high spatial resolution of captured images. In this approach, phase-based motion extraction (PME) is compared to a template matching and particle filter (TMPF) hybrid approach for magnification and frequency extraction. In addition, the methods are also tested on a pedestrian bridge to monitor changes in dynamics given a variation of loading scenarios.
