A suite of tools for the management of 3D scanned data
Rocchini C., Cignoni P., Montani C., Pingi P., Scopigno R.
In this paper we describe a 3D scanning software suite which gives support to most of the processing phases of a complex 3D scanning project. In particular, our tools support: range maps alignment, range maps merge, mesh editing and mesh simplification. The software suite has been implemented by scratch and encompasses both up-to-date solutions (alignment, editing) and some original methods (merging, simplification, and, in part, alignment). The architecture of the software suite is described and an evaluation of its use in the framework of a complex acquisition in the Cultural Heritage domain (3D scanning of a bronze statue) is reportedSource: Italy-Canada workshop on 3D digital imaging and modeling, Padua, Italy, 2001

Restoring David using 3D
Callieri M., Cignoni P., Ganovelli F., Montani C., Impoco G., Pingi P., Ponchio F., Scopigno R.
Refurbishing Michelangelo's David has produced several useful restoration guidelines. These guidelines can help restorers select the proper procedures for the task and, objectively, assess the results. The work also has helped us develop innovative ways to process and visualize 3D data in cultural heritage projects. The David restoration was an ideal test bed. We try various methodologies to support restorers and scientists with visualization tools based on 3D digital models. 3D digital models can be a tool for undertaking specific investigations, or as supporting media for archiving and integrating the restoration-related information.Source: IEEE potentials 23 (2005): 4–7. doi:10.1109/MP.2005.1368908

A machine vision system controlling the cutting of animal hide
Fantini E., Ganovelli F., Pingi P.
Based on the integration of image acquisition techniques and real-time systems, an innovative system for cutting raw hides has been developed at ISTI-CNR. The aim is to partly automate the cutting process, so that minimal human intervention is needed. The current procedure for cutting animal hide is completely manual. The hide is spread out on a bench and expert operators decide the best cutting lines on the basis of the location of specific features. The hide is then manually cut using ad hoc knives and the parts are removed from the bench. The work of cutting the hide is the most time consuming step, and requires three or four workers.Source: ERCIM news 55 (2003): 32–33.

The Marching Intersections algorithm for merging range images
Rocchini C., Cignoni P., Ganovelli F., Montani C., Pingi P., Scopigno R.
A new algorithm for the integration of partially overlapping range images into a triangular mesh is presented. The algorithm consists of three main steps: it locates the intersections between the range surfaces and a reference grid chosen by the user, then merges all nearly coincident and redundant intersections according to a proximity criterion, and, finally, reconstructs the merged surface(s) from the filtered intersection set. Compared with previous methods, which adopt a volumetric approach, our algorithm shows lower computational costs and improves the accuracy of the surfaces produced. It takes into account the quality of the input measurements and is able to patch small holes corresponding to the parts of the 3D scanned object that were not observed by the acquisition device. The algorithm has been tested on several datasets of range maps; graphical and numeric results are reported.Source: The visual computer 20 (2004): 149–164. doi:10.1007/s00371-003-0237-8

Visualization and 3D data processing in the David restoration
Callieri M., Cignoni P., Ganovelli F., Impoco G., Montani C., Pingi P., Ponchio F., Scopigno R.
The program of scienti?c investigations planned in the framework of the restoration of Michelangelo's David produced several useful guidelines for de?ning and developing innovative ways to process and visualize 3D data in cultural heritage applications. Our ultimate goal was to include 3D graphics among the tools which can help restorers select the proper restoration procedures for the task at hand and objectively assess restoration results. For this, the David restoration was an ideal test bed to demonstrate the usefulness of digital 3D models and visualization tools in a restoration project. The scientific analysis program began in Florence, Italy, in 2002, under the direction of Mauro Matteini and Franca Falletti. Because a complex set of scientific investigations was planned before and after the restoration intervention, we could try various methodologies to support restorers and scientists with visualization tools based on 3D digital models. In particular, a 3D digital model can support restoration either as a tool for undertaking speci?c investigations or as a supporting media for archiving and integrating the restoration-related information, gathered with the different studies and analyses performed on the artwork.Source: IEEE computer graphics and applications 24 (2004): 16–21. doi:10.1109/MCG.2004.1274056

A low cost 3D scanner based on structured light
Rocchini C., Cignoni P., Montani C., Pingi P., Scopigno R.
Automatic 3D acquisition devices (often called 3D scanners) allow to build highly accurate models of real 3D objects in a cost- and time-effective manner. We have experimented this technology in a particular application context: the acquisition of Cultural Heritage artefacts. Specific needs of this domain are: medium-high accuracy, easy of use, affordable cost of the scanning device, self-registered acquisition of shape and color data, and finally operational safety for both the operator and the scanned artefacts. According to these requirements, we designed a low-cost 3D scanner based on structured light which adopts a new, versatile colored stripe pattern approach. We present the scanner architecture, the software technologies adopted, and the first results of its use in a project regarding the 3D acquisition of an archeological statueSource: Computer graphics forum (Print) 20 (2001): 299–308. doi:10.1111/1467-8659.00522

Il modello digitale 3D del David e il suo uso nel progetto di restauro
Scopigno R., Callieri M., Cignoni P., Ganovelli F., Montani C., Pingi P.
Le moderne tecnologie di scansione digitale tridimensionale permettono di ricostruire, in maniera semi automatica, rappresentazioni digitali di oggetti reali caratterizzate da un alto grado di accuratezza e di ricchezza di dettaglio. Un accurato modello digitale del David di Michelangelo e' stato creato nell'ambito del progetto Digital Michelangelo. La disponibilità della rappresentazione digitale apre ampie possibilita' di utilizzo da parte degli addetti ai lavori (restauratori, archivisti, studiosi) od anche di semplici visitatori (virtuali e non). L'integrazione tra grafica 3D e tool di supporto al restauro e' un campo di ricerca aperto ed il progetto di restauro del David ha fornito numerosi spunti per la definizione e lo sviluppo di soluzioni innovative. L'attivita' del nostro gruppo si e' indirizzata su problematiche proposte direttamente dell'equipe di restauro e qui brevemente descritte. Il modello digitale e' stato usato in due accezioni diverse ma complementari: come strumento con cui eseguire indagini specifiche, o come supporto per l'indicizzazione e l'integrazione dei risultati di altre campagne di indagine.Source: Kermes (Firenze) 16 (2003): 45–49.

Derma: monitoring the evolution of skin lesions with a 3D system
Callieri M., Cignoni P., Pingi P., Scopigno R., Coluccia M., Gaggio G., Romanelli M.
We present a new integrated tool, DERMA, which allows to measure and assess the time evolution of chronic wounds. A laser triangulation 3D scanner is used to acquire the wound geometry with high precision and to capture an RGB image aligned to the geometry. DERMA provides a single and uniform interface to: manage patient data, 3D scanning of the lesion region, and to perform different kinds of measurements and comparisons: geometric (on the 3D model) and colorimetric (on the image). All acquired data (3D geometries and images) as well as the measures calculated are stored in a database for monitoring the evolution of the skin lesion over time. The tool, developed in collaboration with dermatologists, is now under field evaluation in two dermatological clinics monitoring the evolution of wounds due to different types of skin diseases.Source: 8th International Fall Workshop on Vision, Modeling, and Visualization 2003, pp. 167–174, Muenchen, 19-21/11/2003

DERMA provides a single and uniform interface to: manage patient data, 3D scanning of the lesion region, and to perform different kinds of measurements and comparisons: geometric (on the 3D model) and colorimetric (on the image). All acquired data (3D geometries and images) as well as the measures calculated are stored in a database for monitoring the evolution of the skin lesion over time. The tool, developed in collaboration with dermatologists, is now under field evaluation in two dermatological clinics monitoring the evolution of wounds due to different types of skin diseases.Source: 8th International Fall Workshop on Vision, Modeling, and Visualization 2003, pp. 167–174, Muenchen, 19-21/11/2003

VCLab's Tools for 3D range data processing
Callieri M., Cignoni P., Ganovelli F., Montani C., Pingi P., Scopigno R
Post-processing of 3D scanned data is still the bottleneck for a wider diffusion of this technology. In this paper we describe our second generation tools for processing 3D scanned data. In particular, our tools support: range maps alignment, range maps merge (or fusion), mesh simplification and color attribute management. This software package has been implemented by scratch and encompasses both up-to-date solutions and some original methods (merging, simplification, color management and, in part, alignment). The paper presents the architecture of the tools, the features supported and algorithms used; finally, an evaluation of its use in the framework of a complex acquisition in the Cultural Heritage domain (3D scanning of a bronze statue) is reported.Source: 4th International Symposium on Virtual Reality, Archaeology and Intelligent Cultural Heritage (VAST2003) and First EuroGraphics Workshop on Graphics and Cultural Heritage, pp. 1–10, Brighton, 5-7 November 2003

Digital reconstruction of the Arrigo VII funerary complex
Baracchini C., Brogi A., Callieri M., Capitani L., Cignoni P., Fasano A., Montani C., Nenci C., Novello R. P., Pingi P., Ponchio F., Scopigno R.
The results of a project aimed to the study, reconstruction and presentation to the public of a monument disassembled and dispersed, the mausoleum of the emperor Arrigo VII, are presented here. We used modern 3D graphics for the acquisition of accurate digital models of all the elements of the funerary complex, to draw hypothesis on its original architecture, and finally to present all this knowledge to the museum public. Issues emerged during 3D scanning are discussed. The multimedia museum presentation was implemented with an interactive visualization system, which was extended to manage standard multimedia data together with 3D geometry.Source: VAST 2004 - The 5th International Symposium on Virtual Reality, Archaeology and Intelligent Cultural Heritage, pp. 145–154, Bruxelles, Belgium, 7-10 December
