Railway bridge condition assessment based on state-of-the-art reality capture technologies: application to a case study

Structural visual inspection documentation is essential for monitoring, maintaining, rehabilitating, and reinforcing structures. Close-Range Photogrammetry (CRP) Terrestrial Laser Scanners (TLS) are cutting-edge technologies that commonly used in surveying. In this article, these were integrated to capture a railway bridge. The lower deck lateral surfaces captured using TLS, while the upper deck, track laterals of CRP-UAV photogrammetry. Post-processing techniques allowed fusion TLS CRP models produce precise 3D model entire bridge deck.
