Bridge post-disaster rapid inspection using 3D point cloud
1. Introduction With the rise in traffic volume globally, vehicle-bridge collisions have become increasingly common, posing severe safety risks and operational challenges for transportation infrastructure. These incidents demand prompt and accurate assessment of bridge damage to ensure structural integrity and guide emergency recovery operations. Traditional inspection methods are limited in their spatial resolution and efficiency, making it difficult to assess complex three-dimensional damage. This study proposes an innovative emergency inspection approach utilizing 3D laser scanning technology for rapid and accurate assessment following vehicle-bridge collisions. 2. Limitations of Traditional Damage Assessment Techniques Conventional bridge inspection techniques, such as visual assessments or point-based measurements, fall short in capturing detailed 3D geometrical data of both the overall structure and localized damage. These limitations hinder a comprehensive understanding...
