In this paper a framework for the rapid seismic risk assessment of bridges using aerial surveys using Unmanned Aerial Systems is presented. The acquisition process to obtain data for the photogrammetric 3d reconstruction and the procedure for the automatic extraction of the visible variables using computer vision are described. The extracted features are combined with standardized structural information to obtain the structure’s capacity model and perform a seismic risk assessment. A case study of a highway simple supported bridge is presented to validate the 3d model reconstruction and the results of the structural analysis.

Abstract
In this paper a framework for the rapid seismic risk assessment of bridges using aerial surveys using Unmanned Aerial Systems is presented. The acquisition process to obtain data for the photogrammetric 3d reconstruction and the procedure for the automatic extraction of the visible variables using computer vision are described. The extracted features are combined with standardized structural information to obtain the structure’s capacity model and perform a seismic risk assessment. A case study of a highway simple supported bridge is presented to validate the 3d model reconstruction and the results of the structural analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
