UAV-Based Photogrammetry and Integrated Technologies for Architectural Applications—Methodological Strategies for the After-Quake Survey of Vertical Structures in Mantua (Italy)

A novel approach using UAV-based photogrammetry demonstrates high precision and efficiency for post-seismic surveys of complex vertical structures, such as the Santa Barbara Bell tower in Mantua, Italy. This methodology integrates unmanned aerial vehicle (UAV) systems with traditional techniques like TLS and topographic acquisition to achieve rapid, cost-effective, and secure data collection. The study compares results from laser scanners, metric cameras, and amateur reflex cameras, showcasing the superiority of image-based methods for capturing intricate architectural details. The resulting 3D database enables comprehensive analysis and intervention planning, proving UAV photogrammetry's applicability in emergency contexts where accessibility is challenging.
