Monitoring Transportation Structure Integrity Loss and Risk with Structure-From-Motion

This report describes methods that allow for assessing structural integrity using a direct porting of imaging methods captured by both hand-held and uncrewed aircraft system (UAS)-assisted photography into computational analysis tools to monitor structural degradation of transportation structures. Of primary interest is the level of accuracy of cracked structures and their evolution over time using structure from motion (SfM). Imaging methods using light detection and ranging (LiDAR) scanning and the modeling of particle flow are also explored, with the focus of these two techniques being longer, more slender structures and the effects of debris flow on transportation infrastructure. Imaging techniques show great promise, with cracks being detected down to the centimeter scale, while finite element and discrete element models also show potential in these image-to-model simulations.
