In this paper a 3D Laser scanner based on the operation principle of Continuous-Wave Frequency Modulated (CWFM) radar is applied to the acquisition of a digital three dimensional model of the worldwide famous ”David” by Donatello. The steps of the acquisition procedure and the related technical solutions are reported. The scientific focus was on the processing pipeline simplification due to the new acquisition methodology. Detailed results are presented, demonstrating how the use of this type of sensor allows to digitize artworks made of materials that are normally very difficult to acquire, and to improve the overall level of modeling accuracy.

Abstract
In this paper a 3D Laser scanner based on the operation principle of Continuous-Wave Frequency Modulated (CWFM) radar is applied to the acquisition of a digital three dimensional model of the worldwide famous ”David” by Donatello. The steps of the acquisition procedure and the related technical solutions are reported. The scientific focus was on the processing pipeline simplification due to the new acquisition methodology. Detailed results are presented, demonstrating how the use of this type of sensor allows to digitize artworks made of materials that are normally very difficult to acquire, and to improve the overall level of modeling accuracy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
