After an earthquake, many resources are spent to evaluate the level of damage suffered by buildings and infrastructure. To improve the efficiency and reduce the subjectivity of such assessments, a robotic total station (RTS) can be a useful support. This work aims evaluates the performance of a RTS for use in emergency conditions. Furthermore, the analysis of reduced configurations of the monitoring points highlights interesting aspects for defining a standardized, simplified procedure.

A method for amplitude–phase calibration of tri-axial accelerometers in the low-frequency range is proposed, based on a linear slide, used to excite all the axes of the accelerometer at the same time, and a laser Doppler vibrometer (LDV) as a reference. Results show that the phase is a critical aspect to consider in calibration, more than the amplitude, and the comparison with the theoretical model is useful to verify the hypotheses. Different behaviours result, depending on the measuring chain.

Low-frequency vibration measurements are of great interest in many fields like energy production, structural health monitoring (SHM) of buildings, geotechnical applications, human vibration and bio-dynamics, mainly because of the increasing development of MEMS embedded in mobile devices and in applications in the field of the Internet of Things (IoT). We investigated the effectiveness and efficaciousness of some available calibration techniques to promote their aware, widespread, use.
