The group applies laser scanning technology as a displacement measurement technique for infrastructure. A three-dimensional point cloud can be collected by the laser scanning and allow for the analysis of displacements of the entire infrastructure. Laser scanning has a low accuracy in the range of millimeters, but the group is improving accuracy by CANUPO, a machine learning method, P2P-TA, etc. as well as via conventional point cloud analysis methods.
