Abstract:Dynamic displacement of bridges under moving vehicle loads is a critical safety indicator for bridges, yet directly measuring these displacements poses practical challenges. Although computer vision-based techniques for measuring displacements have gained application, they are influenced by environmental conditions. Alternatively, indirect estimation of bridge displacements has attracted great attention. Currently, some deep learning methods have been developed to estimate displacements at positions deployed w… Show more
