Summary: Previous studies mainly focused on cracks and leaks in tunnel damage measurement methods, with little research on siltation at the bottom of water conveyance tunnels. This paper proposes a 3D measurement framework based on image 3D reconstruction technology for accurate measurement and intuitive understanding of underwater siltation. The method utilizes structure from motion (SfM) and multi-view stereo (MVS) algorithms to generate 3D point clouds of siltation, which are further processed to obtain accurate measurements of siltation thickness and area.
