One of the most vital duties for engineers is to preserve life and nature by utilizing safe designs that take into account environmental standards and monitoring the performance of structures against design criteria. Furthermore, monitoring can be used to determine any required maintenance of an important structure following a catastrophic event. Numerous different techniques and instruments can be used for this purpose. These methods have different requirements and produce different results. For instance, some techniques need to embed sensors inside the building, such as geotechnical Sensors. Other methods can offer high accuracy, but with a low density of points and requiring fixed stations and targets, like total stations. Interestingly, a lot of researches are focusing on using terrestrial laser scanning (TLS) for monitoring owing to many outstanding performances it offers. However, there are two challenges of using TLS in monitoring: the first one is the noise associated with TLS data; the second one is the difficulty to compare images between two epochs because the observations of TLS are not repeatable. In spite of the fact that numerous researchers have investigated and developed different techniques to determine deformation from TLS data, it still needs more investigation. The aim of this research is to develop a new approach to detect deformation from TLS measurements. This approach is based on the Generalised Procrustes Analysis Technique (GPA). Through this technique, it is possible to determine and detect deformation not just between two epochs, but for a sequence of epochs. This can provide more a precise deformation model. Validation process has shown that the optimistic results could be achieved where millimeter deformation can be detected by the proposed technique.
