Damage Signature Generation of Revetment Surface along Urban Rivers Using UAV-Based Mapping

Damage Signature Generation of Revetment Surface along Urban Rivers Using UAV-Based Mapping

The all-embracing inspection of geometry structures of revetments along urban rivers using the conventional field visual inspection is technically complex and time-consuming. In this study, an approach using dense point clouds derived from low-cost unmanned aerial vehicle (UAV) photogrammetry is pro...
