Francesca SOLINAS | Luca ALBERGONI (Dipartimento di Architettura Florence University, Firenze, Italy) Keywords: Florence 3DLaserScanner 3DPhotogrammetry VirtualTour360° Abstract: The Bellini Family has been one of the most prestigious Florentine antique collectors and since the seventeenth century to the present time. Their gallery is aimed to preserving the collections in the wake of the great Florentine Case Gallerie antiquarie (galleries and auction houses) that arose between the 19th and the 20th centuries therefore witnesses the Florentine historical legacy. Located in Lungarno Soderini the museum overlooks Ponte alla Carraia. In modern times it has undergone various reworkings before adopting the current configuration through the work of the architect A. Coppedé. The analysis of the building moves from a historical and cartographic research on archive sources and it relies on bibliographies. It has been articulated in two survey campaigns which involved the use of the 3D photogrammetry and 3D Lasers Scanner. Following a specific request by prof. Bellini, a subsequent campaign was furthermore carried out using a 360 ° panoramic video-photography of the galleries on the two levels of the building, At a later stage the collected data have been processed to obtain a three-dimensional texturized reconstruction of the main elevation, and the cloud of points of the entire building. This has been followed by the restitution of the high resolution orthophoto of the façade and of the geometric survey of the structure, with the identification of its material characteristics and critical situations. In the final phase of the project hypotheses of intervention are proposed to respond to regulatory requirements, maintaining and enhancing the two current functions of the building: the contemporary art gallery and the antique...

It was located at the Spitalfields suburb, (Spital Yard), actually Bishops Square, E1 6AD London (UK). The site is located below the street level, in a new area that has been completely restructured. Through a public staircase it is possible to access a wall of glass that allows to see a side of the medieval building, although access to the interior remains closed to the public. It can only be visited in groups and upon a booking to Historic England, entity in charge of its management, custody and maintenance. Through this glass it is possible to observe a part of the site. The ruins has been surveyed and documented using photogrammetry solutions to create a base for further virtual 3D reconstruction. A set of references from proper manuals about gothic and neogothic architecture has been the base for this digital modeling. The poster presented here has been made to be placed on the site; It has been arranged inside the glass, suspended from the roof, so that its texts can be read, as well as its images and the QR codes taking to digital 3D models of the site and its hypothetical reconstruction. Also, traceries, jambstones, ribstones that have been used to make the reconstruction and that are in the storage of the MOLA (Archaeological Museum of London) are...

Iulia DANA NEGULA | Cristian MOISE | Radu Claudiu FIERASCU | Irina FIERASCU | Constantin Ioan INEL | Ioana POPITIU (Romanian Space Agency, Bucharest, Romania) Keywords: remote sensing, nanotechnology for conservation and restoration, digital reconstruction Abstract: Cultural Heritage has a major significance for the local community. The bond between heritage and community represents a bridge that connects the past and the present and it symbolizes the legacy that will be passed on to future generations. Recent studies show that the link between heritage and community “generates values like identity, tradition, the feeling of belonging, social cohesion”. Moreover, the local communities acknowledge the benefits of heritage that primarily reside in tourist development followed by the safeguarding of the local identity and traditions and knowing of the past. Likewise, cultural heritage has a critical value in building and cultivating the local identity. The undeniable process of climate change increases the vulnerability of the natural and cultural heritage sites. Considering the long-lasting efforts carried out to protect and preserve the cultural and natural properties, a special emphasis is put on heritage management and sustainability and also on the implementation of the digital heritage concept. In this context, the knowledge of the current state of conservation is essential. Suitable for both cultural and natural heritage, satellite data enables the generation of custom-made monitoring products, such as land use and land cover maps, multi-temporal analysis and change detection, digital elevation models, displacement maps, etc. The RO-CHER project (“Multidisciplinary complex project for the monitoring, conservation, protection and promotion of the Romanian cultural heritage”) proposes a multidisciplinary innovative approach for safeguarding the cultural heritage. It aims at monitoring the cultural heritage objectives with the support of space technologies, developing materials and innovative techniques based on soft nanomaterials, recommending an integrated management system (conservation, restauration, protection), and promoting cultural heritage by using state-of-the-art technologies of digital reconstruction. The results of the project will support the national and local authorities responsible for the protection of the cultural...

Ambra COLACIONE | Paolo FORMAGLINI | Filippo GIANSANTI | Alessandro GIACOMELLI (Dipartimento di Architettura, DIDA UNIFI, Florence University , Italy, Florence, Italy) Keywords: Photogrammetry, Structure from Motion, Maddalena ’s Bridge, Data comparison Abstract: How can we make the heritage built around us available through the new digital survey technologies? The Maddalena bridge, in Borgo a Mozzano (LU) Italy, called “Devil’s Bridge”, is a monument of particular historical interest and it has been analyzed here with the aim to identify new way about how to use the data of a survey campaign through using different technological methodologies (laser-scan and photogrammetry) and new SFM software. The use of both data allows a greater knowledge of detail and better management of the survey campaign timing. Some buildings, such as a bridge, located in particular topographical conditions may present some difficulties with survey ’s technologies. In this case, the water affected the normal return of the data through the laser scan; also the photogrammetric survey sessions obviously present physical barriers such as in our case the river, not navigable at the time of the survey campaign. Therefore, the combined use of both laser-scan and the photogrammetric survey was indispensable in order to provide better detail accuracy. The new survey made in 2018 and its graphic restitution of Maddalena ’s Bridge, wants to offer itself as a usable basis to benefit from a comparison with a previous survey carried out in 2006, allowing us to analyze and compare the status of the current fact with the previous one and thus allowing to hypothesize possible consolidation and redevelopment interventions if necessary. It was thus possible to highlight the changes offered by the new technological solutions that we now have available (the evolution of the Laser-scan, optical devices and cameras, software and digital components) that allow us to implement the knowledge of the survey. Thanks to the survey itself, it was possible to create a 3D digital model available for complete use of the monument for tourism...

Marco TANGANELLI | Giorgio VERDIANI | Federica PAOLUCCI (Dipartimento di Architettura, Florence University, Florence, Italy) Keywords: Photogrammetry, Statues, Bargello Museum, Seismic Vulnerability, Resilience Abstract: In recent years, more and more attention has been paid to creating safeguards measures in protecting masterpieces, art items, large statues, from the uncontrollable event of an earthquake. In the poster presented here a specific research about this subject will be brought to the attention of the conference participants: It will be shown how, from a set of significant statues from the Bargello Museum in Florence, Italy, it is possible to define a working model for simulating the effects of an earthquake and understand the real state of safety of these artworks. While the correct definition of the shape of the elements is fundamental in this processing, a particular attention will be given to the phase of digital survey, here operated using photogrammetry based on Structure from Motion procedures. All the steps of the workflow will be analyzed and described in its main issues, lessons learned, new procedures. A set of different procedures will be compared, a speditive method based on a smartphone camera and quick and simple modeling to one based on a 50 Mp resolution camera with high quality optic and highly accurate modeling. The result of the two procedures will be matched to the results of the simulation analysis, suggesting affordable approaches for any similar conditions about the interpretation of the state of safety of this important cultural...
