Title : Digitalisating and visualising scientific and technical Cultural Heritage artefacts thanks to 3D imaging techniques: a critical review and possibilities of matching techniques versus artefacts

Project Lead : Romain Jeanneret From : Haute cole de conservation-restauration Arc (None)

Dates : from 2014-02-10 18:03:15 to 2015-01-31 00:43:08

Description :

Motivation and objectives :
The objective will be to get an overview of the different 3D imaging techniques that can be used on ST Cultural Heritage objects and to see which technique fits the best to the artefact under consideration as regards the shape and the surface rendering. Eventually techniques that are the most accessible to end-users (conservation professionals) will be further investigated to precise the conditions of a complete survey of a series of artefacts that are representative of those usually found in our domain of expertise. Techniques that will be considered: 3D scanning, SLM (Structure from motion /photogrammetry), reverse-engineering, virtual representation and immersive simulations

Teams :
Romain Jeanneret (RJE) is a conservator specialised in the conservation of historical scientific and technical (ST) objects as well as a drafter trained in the use of mechanical CAD software. In addition he is teaching computer graphics to the Master students at the HE-Arc CR.He has participated to the EU COST Action COSCH training school in Warsaw last autumn which has convinced him to further develop his skills in the use of the most appropriate 3D imaging techniques to document ST artefacts. RJE will participate from March 2014 onwards to the 2-years Swiss national project - SCHEMA-TEC- dedicated to the use of the most appropriate imaging methods to document ST artefacts. Therefore this Trans National Access should be an additional step to the inclusion of 3D imaging techniques in the whole documentation process of these artefacts. Christian Degrigny (CDE) is professor at HE-Arc CR. He will be the coordinator of the SCHEMA-TEC project. Furthermore he is the Swiss delegate of the EU COST Action COSCH. CDE and FLA are collaborating within COSCH in WG4: Analysis and restoration of CH surfaces and objects. Florent Laroche (FLA) is assistant-professor at Ecole Centrale de Nantes (France) and member of IRCCyN (Research Institute for Communication and Cybernetics of Nantes, France - UMR CNRS 6597) specialised in virtual reality technologies applied to digital heritage such as 3D visualisation of industrial artefacts and site. FLA has worked extensively on the translation of knowledge of the past in contemporary knowledge, readable and understandable in the present socio-technical system. One objective of this research is to reuse the technical heritage as a basis for innovation. His research topics are KM, PLM, information system modelling, interoperability, enterprise modelling, virtual engineering, reverse engineering.

Conclusions :
Results / work achieve Previous stay have been discussed and finished; work had resulted in constraints that must be taken into account in the methodology. However, formalizing the methodology is so complex. Work have began but is not net finish. Perspectives / Work to be done in the future As explained before, thanks to this TNA, a strong collaboration had been established. The collaboration allow to create common vocabularies and exchange best practices. A new project called Schema-Tec had been accepted and will be hosted by Romain Jeanneret team during two years. Romain Jeanneret will apply for a project about 3D scanning of technical cultural heritage beginning autumn 2015. It will be introduce to an internal University of applied science of Western Switzerland (HES-SO) funds. A collaboration with IRCCyN is planned. Scientific valorization possibilities thanks to the TNA A scientific paper is in preparation. Both point of view will be developed and the communication published in both reviews: for mechanical engineering and also for cultural heritage.
