CAD-BASED METHODS APPLIED TO THE RECONSTRUCTION OF ARCHAEOLOGICAL REMAINS

By means of a three-dimensional laser system, archeological remains resultant of excavations in a castro of Galicia were scanned, being obtained in the first place different loose parts of the external surface of every piece. Next, methods were applied to generate the integral surface of each piece from the different loose parts or patches. As main objective, it was developed and implemented two methods for virtual reconstruction of incomplete archaeological remains. These methods are based on the integration of traditional methods of archaeological drawing with CAD (Computer Aided Design). Moreover, from the superficial model of each piece, methods were studied for the generation of a complete solid model of each one, thus being able to keep internal information (material, density, etc.) of the objects, with the possibility of making cuts of all type.
