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