Abstract: Matching procedure for the digital modelling of objects by means of stereoscopic images comprising at least the steps of acquiring a pair of stereoscopic images of an object to be reconstructed, of discretizing the object space according to an elevation direction (Z) and for each primitive, of identifying a better elevation coordinate by means of the application of a similarity criterion to the stereoscopic images acquired.

Abstract: System for measuring coseismic movements or vibrations of structures based on measurements of phase observations performed on at least four sources simultaneously, between GNSS satellites and/or pseudolites, for couples of consecutive timepoints (t,t+1) temporally separated by not more than one second.

Abstract: Lever device for double-action remote-control, i.e. of rigid tie rods and/or flexible cables, consisting of a lever (12) rotatable in respect of a base element (13), connectable (in 14) to a carrying structure external to an operating machine in which the device (11) is contained into bellows (10) connected-to the base element (13) while the lever (12) is connected to a mobile component (15) from which the elements to fasten the ends of two cables (22) for remote transmission extend and the base element is coupled to two reaction sheaths (21) of the two transmission cables (22), three ball elements (16, 16'), placed at 90.degree.
