In this study, the creation of a 3D digital model of a bridge structure by applying computer vision technology to LiDAR point cloud data acquired through laser scanning is proposed for determining structural damage. This method first identifies and labels the individual components of a bridge and then creates a detailed 3D digital model of its structure. An octree data structure is used to efficiently store and process the point cloud data to create the digital model.
A static loading test on an actual bridge structure demonstrated the effectiveness of the proposed method in identifying individual components and analyzing the structural deformation. Based on the results, a 3D digital model can be used to identify structural damage to bridges during bridge inspection, monitoring, and maintenance.
