Title: Three-dimensional television (cinematographic, photographic) filming system in which the parallax and shooting angle are variable according to the physiological characteristics of the stereoscopic vision of the human eye, and are calibrated instantaneously by precise information provided by a special binocular viewfinder.
Inventor: GREGORIO ELENA
IPC: G03C/
Filed: 1991-02-18
Granted: 1995-02-23
Abstract: The three-dimensional television (cinematographic, photographic) filming system essentially differs from those used up to the present time in that it provides perfect stereoscopic viewing for any person. This is made possible because the two adjacent television cameras (cine cameras, etc.) do not remain fixed (with their optical axes parallel) but can be moved and rotated, according to the various filming requirements, behaving in exactly the same way as the human eyes when they view image. These movements and rotations can be carried out either manually or automatically with great precision, because the data concerned are supplied by a special opto- electronic binocular viewfinder. <IMAGE>

Abstract: Viene descritto un sistema basato sull'abbinamento di una telecamera (10) ad una macchina di misura (5) in modo da fornire una completa libertà di posizionamento della telecamera all'interno del volume di misura della macchina, sostituendo la presa di punti manuale e la definizione delle traiettorie dei sistemi di misura tradizionali, utilizzanti palpatori, con una semplice inquadratura della porzione di superficie da misurare, dotata di linee a forte contrasto rispetto alla superficie stessa. Il sistema comprende un elaboratore di immagini (16) che controlla l'acquisizione di due differenti immagini della superficie, per localizzare le linee a forte contrasto. Un elaboratore stereo (17) provvede quindi a correlare fra loro i punti delle due immagini, a calcolare le coordinale tridimensionali di lati punti e le equazioni delle curve e delle superfici passanti per tali punti.Figura 2.
