Change detection and deformation analysis using Terrestrial Laser Scanning: Case study of the metro tunnel at Rotterdam central station

A Terrestrial Laser Scanner (TLS) is a powerful tool for surveying. Tens of millions of points are acquired with a high accuracy and within a short time. The resulting point clouds can be used to find changes and deformations. For this project, four point clouds of the metro station and tunnel at Rotterdam central station are available. The...
