National audience; Technical imaging has always been an essential tool in conservation science. Thanks to today’s digital photography and its quantitative and qualitative tridimensional aspects, this imaging has become an autonomous and vital nondestructive instrument that complements classic physical and chemical analyses. It is also an essential tool for documentation purposes. Results coming from different techniques of analysis can now be synthesized by means of new developments in technical imaging and their insertion into collaborative 3D semantic annotation platforms. Technical imaging can modify the infield approach of conservation professionals and will help lead to better interprofessional dialogue in the future. Conservation professionals will have the assurance of better consistency in their observations, which can cover different time frames for restoration projects and historical data and conclusions drawn from analyses made at different scales. In the long term and after integration of environmental data, these platforms will become monitoring tools dedicated to following the state of conservation of cultural heritage objects and a tool for transmitting knowledge about these objects to a wider audience.; L’imagerie scientifique est un outil incontournable des sciences de la conservation-restauration. La modification du support de la photographie, devenu numérique, le développement du rendu tridimensionnel qualitatif et quantitatif de l’image ont transformé la photographie technique en un outil d’investigation non destructif à part entière, indispensable et complémentaire des approches physiques et physico-chimiques classiques et en un outil-support de documentation. L’ensemble des développements et travaux menés en imagerie scientifique et sur l’intégration dans des plateformes collaboratives d’annotation sémantique 3D permet, outre une production plus facile de documents, de mettre en synergie les résultats provenant de différentes techniques d’analyse. Elle va modifier, dans un futur proche, l’approche sur le terrain des acteurs de la conservation et conduire à une meilleure synergie interprofessionnelle. Ils auront ainsi la possibilité de mieux mettre en cohérence leurs observations, leurs conclusions quant aux analyses faites à différentes échelles, dans une dynamique temporelle qui intègre les données de la restauration, de son histoire passée. À terme, et par l’intégration des données environnementales, ces plateformes seront un outil de suivi de l’évolution de l’état matériel du bien culturel et aussi de transmission des connaissances vers un public large.

Le plafond à la française de l’ancienne maison du viguier à Puisserguier (Hérault) montre d’intéressants restes de polychromies datant du tout début du XVIe siècle. L’état de dégradation avancé de la matière picturale est cependant à l’origine de certaines modifications chromatiques qui ont pu être mises en évidence par le biais d’analyses physico-chimiques et de l’imagerie scientifique. Nous verrons comment ces outils technologiques ont permis la compréhension des processus d’altération de la matière mais aussi comment ils ont joué un rôle fondamental dans la connaissance du décor original et des modifications qu’il a subi depuis sa création jusqu’à nos jours. The French-style ceiling of the former house of the medieval judge in Puisserguier (Hérault) has interesting remains of paintings from the early 16th century. However, advanced ageing of the pictorials is causing chromatic changes which were highlighted by means of physicochemical analysis and technical imaging. We will see how these techniques have constituted a very useful tool for the understanding of material degradation processes and helped to figure out how the original decoration was without the climate modifications it has been subjected to since its creation.

Private nurses have an important role to play in the healthcare system, notably within the framework of outpatient surgery. They are often underestimated, but they are on the front lines when it comes to informing patients, reassuring them and caring for them. They must therefore master the processes of outpatient surgery and those of enhanced recovery after surgery. Their skills need to be upgraded.

In the field of wall paintings studies different imaging techniques are commonly used for the documentation and the decision making in term of conservation and restoration. There is nowadays some challenging issues to merge scientific imaging techniques in a multimodal context (i.e. multi-sensors, multi-dimensions, multi-spectral and multi-temporal approaches). For decades those CH objects has been widely documented with Technical Photography (TP) which gives precious information to understand or retrieve the painting layouts and history. More recently there is an increasing demand of the use of digital photogrammetry in order to provide, as one of the possible output, an orthophotomosaic which brings a possibility for metrical quantification of conservators/restorators observations and actions planning. This paper presents some ongoing experimentations of the LabCom MAP-CICRP relying on the assumption that those techniques can be merged through a common pipeline to share their own benefits and create a more complete documentation.

The present paper presents the results of petrographic and physico-chemical analyses carried out on small Archaic limestone aedicula – some of which were painted – discovered in Marseille in the 19th century. This interdisciplinary, collaborative project was set up within the framework of an archaeological study., Le présent article expose les résultats des analyses pétrographiques et physico-chimiques menées sur les petits édicules archaïques en calcaire, pour certains peints, découverts au xixe siècle à Marseille, grâce à une collaboration interdisciplinaire mise en place dans le cadre d’une étude archéologique.

International audience; When documenting and analyzing cultural heritage, the monument states can be described by multitemporal data sets, which however present a complication for the elaboration and examination process. This difficulty leads to the necessity to improve the analyze process in order to expand the documentation process and help experts to enrich and share information about the historical buildings. Therefore an approach of change measurement, which supports the chronical comprehension of a building by visualizing and quantifying the dimensional temporal effects was elaborated, where the analyze process of a multitemporal data set was based on the interpretation of depth map images. These maps were obtained by generating ortho images of an object that was created on purpose by setting up an experimentation to acquire a multitemporal data set. This approach is the first step of a wider ongoing research about change detection processes on multitemporal data sets. Index Terms-Change measurements, multitemporal data set, depth map, ortho image, evolution of deterioration patterns.

International audience; One of the main issues in the conservation of wall paintings is to understand the origin of the degradation and to detect the deterioration patterns before any loss of material occurs. A toolbox of Non Destructive Techniques (NDT) has been developed. It aims to establish a precise conservation diagnosis according to two approaches: a campaign in the field using multianalytical techniques and data compilation in a multidimensional database. Several NDT techniques were used to analyze Giovannetti's wall paintings in La Chartreuse (Villeneuve-lesAvignon, France) in an experimental mission. Some of the techniques give information about the inner and the outer surfaces of the mural and wall while others inform on structural aspects which mainly concern the mortar. Thus, LIBS, digital images of material fluorescence under UV light, photogrammetric results and maps of deterioration patterns have been created from analysis of the painted surface. Investigations on the inner defects and surfaces included stimulated IR to provide additional information to aid conservation strategies. In a second step, all the information was compared including old images and documents from previous restoration campaigns. Finally, all the documentation is inserted in a specific database which allows the superposition and comparison of images arising from different origins. The paper discusses the choice of appropriate NDT tools and the importance of being able to cross-reference the data from a conservation perspective by using of a multidimensional database. This combination of a NDT toolbox with a specific database enables enhanced interpretation of the degradation mechanisms, essential to understand outdoor masonry or the impact of past restoration acts on the wall painting. In addition, it is able to show the evolution of these deterioration

International audience; Matteo Giovannetti's frescoes (1355-1356) which decorate the Innocent VI chapel of La Chartreuse du Val des Bénédictins (Villeneuve-lez-Avignon, France) are very sensitive to the alteration. They need a new restoration campaign. Because of the geometrical complexity of the place, the environment and the involved degradation mechanisms, a good conservation management of these murals is essential. Therefore, an interactive 3- dimensional spatial database, including dated data was developped. Architectural measurements, digital scientific documentation were gathered. A historical documentation including restoration acts, used restoration products has been collected. Last, the paintings degradations, up-to-date deterioration patterns description and conservation state diagnosis of these wall paintings including a deterioration mapping are monitored. Results of the physical and chemical analyses of painting, restoration techniques and deterioration products are also integrated. The entire collected and interactive database will be available for conservation managers and researchers within the next three years.
