Image and Range-Based 3D Acquisition and Modeling of Popular Musical Instruments

This article aims to illustrate the importance of the contribution of 3D survey and modeling techniques in the framework of movable heritage and museum collection documentation and cataloguing. The work reported in this study focuses on digitalization and 3D modeling of some popular music instruments (belonging to the collection of Museo del Paesaggio Sonoro in Italy) in the framework of the SAMIC project (Sound Archives & Musical Instruments Collection). Different sensors and strategies have been applied during this research in order to obtain high-resolution digital replicas of the objects (a LiDAR system and a photogrammetric approach have been tested). The digital datasets modeled with the different techniques were compared in order to evaluate the quality of the models and their metric accuracy.
