Sistema RestArt per la ricomposizione ad alta precisione di opere d'arte lapidee frammentarie

The RestArt method is an innovative mechatronic-based procedure, developed by the architect Nardelli, for high-precision reassembly of stone fragments intended to improve the restoration of ancient statues and architectural elements. The procedure comprises high-accuracy 3D laser scanning of two fragments positioned on the RestArt machine. After virtual reconstruction through best-fitting algorithms, the machine guides the drilling system for high-precision rods insertion and moves one fragment to match the other one. The mechanical resistance of stone specimens reassembled by the RestArt and the traditional methods was tested by strong motion vibration experiments on shaking table.
