Bridge over 30 years account for 35% of all Bridges, because of rapid economic development and urbanization. The structure can’t maintain its original shape due to natural disasters and loads, and deformation occurs. The accidents caused by the deformation of the structure have become a common news in the surroundings. In this study, vertical deflection deformation was measured using a terrestrial laser scanning equipment to measure deformation of the structure. The point cloud data was matched using the ICP algorithm and the vertical deflection value was estimated by the Hausdorff distance. Therefore, this study proposes a noncontact shape management monitoring method that can check structures and detect deformation.
