To monitor the deformation of a civil engineering structure is getting more and more important. For example, a plant, a tunnel, an oil tank or a building is necessary to monitor its deformation for safety. Usually, a surveying instrument such as a total station, a level or a GPS receiver is applied to complete the monitoring work. This project aims to integrate the surveying instruments, the physical measuring instruments and the 3D laser scanner to promote the precision of the deformation data. The conventional monitoring method usually applied spirit levelling and GPS surveying to analyze the deformation of a structure. In this project, the surveying instruments, the 3D laser scanner and the physical measuring instruments are integrated to complete the monitoring work. Therefore, not only the 3D coordinates' deformation can be analyzed but also the physical situation of a structure can be estimated. Consequently, the deformation of a structure can be future understood and controlled.
