Abstract
A system for localizing an object of interest in a monitored space includes a plurality of capacitive sensors for sensing changes in the status of a space, adapted to electrically interact in a contactless way with a ground surface so as to provide a capacitance varying on the basis of such changes, and adapted to detect at least a time evolution of the capacitance and to produce a capacitance-depending signal, a filtering unit configured for reducing the noise level in the time evolution of such capacitance by filtering the capacitance-depending signal provided by the capacitive sensors, so that corresponding filtered signals are produced, and a central device in signal communication with the capacitive sensors. The central device is configured for acquiring the filtered signals of each capacitive sensor, and for determining the position of the object of interest inside the space by inferring at least a distance of the object on the basis of the filtered signals acquired from at least one of the sensors detecting the object, and by combining the at least a distance with positional data defining the positions of the plurality of capacitive sensors in the monitored space.
