Electronic Photo-Optical System For Surveying, Digitalizing And Reproducing The External Surface Of A Three-Dimensional Object, Either Virtually Or In Plastic, Composite Or Papery Material

An electronic photo-optical system for surveying, digitalizing and reproducing the external surface of a three-dimensional object, virtually or in plastic, composite or papery material, comprising an integrated module for calculating and managing informatics data, a scanner module and a reproduction module, characterized in that said integrated calculation module (VT-DataII) describes the mathematical logic utilized in the hardware in the scanner module (VT-MSII) and the reproduction module (VT-MFII) and carries out the operations of:

• i) surveying, by means of a digital photo camera or a digital image survey and acquisition system, an image sequence of the object to be acquired associated with a consecutive and synchronized sequential projection, positioned and moved in predetermined steps, of a linear light beam projected parallel to the plane (x,y) on which the object is placed and striking the surface of the object to be surveyed;
• ii) processing the information acquired as in i) above and reproducing the mathematics that describe the geometry of the external surface of the acquired object taken as model, generating the space coordinates of said object in accordance with a Cartesian reference system with three axes (x,y,z) as logic of the integrated calculation model (VT-DataII);
• iii) transferring the mathematical data acquired as in i) and ii) above to a PC for a virtual reproduction of the acquired object;
• rendering it available by means of specific software to the CAD 3D systems in order to be able to carry out modification interventions;
• iv) transferring to a remote station the mathematical data acquired as in i), ii) and iii) above in order to reproduce there by means of reproduction module (VT-MFII) a copy in plastic, composite or papery material of the external surface of the object acquired by the scanner module (VT-MSII) or the external surface of a PC-generated virtual object transferred by means of specific software from a CAD 3D file to a 3Dr, 3Drrt and 3Dc-type data file, in accordance with the logic indicated by the integrated calculation module (VT-DataII);
• v) colour printing the external surface of the object to be reproduced in plastic, composite or papery material by using the 3Dc-type data file format, in accordance with the logic indicated by the integrated calculation module (VT-DataII).
