摘要: SUMMARY Structural monitoring and structural health could take advantage from different devices to record the static or dynamic response of a structure. A positioning system provides displacement information on location moving objects, which is assumed be basic support calibrate any mechanics model. The global provide satisfactory accuracy in absolute measurements. But requirements an open area position for antennas roofed room its data storage power supply limit flexibility applications. Several efforts are done extend field application. alternative local system. Non-contact sensors can easily installed existing infrastructure locations without changing their properties: several technological approaches have been exploited: laser-based, radar-based, vision-based, etc. In this paper, number options, together with performances, reviewed.
