Radar multi-input multi-output E sistemi di computer VISion per il mONitoraggio degli spostamenti di infrastrutture
Project The research project aims at exploring new technologies to improve the efficiency and to reduce the costs of infrastructure health monitoring systems. In particular, the project involves the use of a multi-input multi-output (MIMO) ground radar and approaches based on video image processing for the direct assessment of displacements, within the context of the digital transition of civil engineering. The monitoring technologies proposed in the project are different from conventional systems, usually based on accelerometers, offering a potentially more efficient and convenient alternative, thanks to their ability to operate in contactless mode, thus eliminating the costly wiring and installation of sensors. The MIMO radar stands out for its ability to simultaneously monitor numerous points of the structure with great accuracy in all environmental and lighting conditions. On the other hand, image processing techniques allow measuring structural movements with less accuracy but at very low costs. The project involves: a) the development of algorithms for the management and processing of radar data and video images; b) testing of the two proposed technologies on laboratory prototypes and on real infrastructures; c) the use of data-fusion techniques based on the Kalman filter to integrate the information acquired from different types of sensors.
