Using IATS and digital levelling staffs for the determination of dynamic displacements and natural oscillation frequencies of civil engineering structures

Image Assisted Total Stations (IATS) unify geodetic precision of total stations with image and video capturing. An appropriate system calibration provided, these images and video frames are accurately geo-referenced at any time. They are particularly suitable for deformation monitoring of civil engineering structures and geo-risk areas, which are very hard to approach. It is also possible to use the additional vision technology for levelling applications by reading and analysing digital levelling staff code patterns. This paper presents the use of IATS, i.e. IATS prototype which consists of RTS Leica TPS1201 and GoPro5 Hero camera. The focus of the paper is determination of simulated dynamic displacements and natural oscillation frequencies by the prototype. For the simulations, we used multi-purpose universal testing machine intended for static and dynamic testing of mechanical properties of building materials and construction in laboratory. The experiments will cover the dynamic displacements from 0.1 to 5.0 mm at the frequency of 2 Hz.
