The approach proposed in this paper has been developed to support the stereo-vision based monitoring of building structures or natural formations focusing on the oscillation measurement. First of all the setup of the measurement system together with the related problems such as the camera synchronization, calibration are shown. The results obtained by the performed experiments point out that the proposed measurement approach considering the achieved frequency and accuracy is suitable to effectively monitor civil engineering and natural structures in a non-contact manner.

TIn this paper a stereo-camera based approach was proposed for the measurement of oscillating and rotating targets. To verify the suitability of the proposed approach for measuring fast moving targets two experiments have been performed. In the first one the trajectories of circular markers attached to a vibrating plate have been measured. The frequency of vibration was about 10Hz. In the second experiment the location of a rotating target has been measured. In both cases the results show that the achieved measurement accuracy and frequency is suitable for structural monitoring of targets in non-contact manner.
