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.

A comparison among three methods for the calibration of tri-axial MEMS accelerometers is presented, paying attention to the uncertainty assessment of each method. The first method is performed according to the ISO 16063 standards. Two innovative methods are analysed, both suitable for in-field application. For each method, the main contributions to the measurement uncertainty have been identified and evaluated, in order to define their most suitable field of application.
