The Technologies of Architectural Survey: A New Comparison Based on the Tower of Sotillo de la Ribera, Burgos
The paper offers an original research about the analysis and the comparison of different techniques of survey concerning the architectural field – image-based and range-based – throughout the development of the theory of errors in order to evaluate reliability and precision of the results. In particular, this analysis will be focused on the tower of the parochial Church of Santa Águeda, a building located in the small village of Sotillo de la Ribera, within the province of Burgos (Spain). The first part of this work, therefore, has been submitted to the implementation of different methodologies, from the direct survey used as a basis, to the procedure to represent graphically the results (e…
THE SCENOGRAPHY OF SERPOTTA STUCCOES REVISITED - MATERIAL AND FORM
The material that lies beneath the smooth shining surface of the stuccoes of the Serpotta family who used to work in Sicily from 1670 to 1730, has been thoroughly studied in previous papers, disclosing the deep, albeit empirical, knowledge of materials science that guided the artists in creating their masterpieces. In this work, attention is focused on the solid perspective and on the scenographic sculpture by Giacomo Serpotta, who is acknowledged as the leading exponent of the School. The study deals with some particular works of the artist, the “small-scaled plastic theatres”, so-called “teatrini”, which he made for the San Lorenzo Oratory in Palermo. On the basis of archival documents an…
Documentación gráfica de la Iglesia de Santa Águeda en Sotillo de la Ribera (España)
The parochial church of Santa Águeda in Sotillo de la Ribera, located in the province of Burgos, Spain is the object of the works of graphical documentation using different methods of survey, which provide a material with different levels of precision, here analysed and confronted. The value of documentation of buildings never surveyed before, enables a much more thorough formal analysis and offers the possibility of contrasting cases with similar features within the territory. The supplementary value added by the knowledge of measures of ancient architectures means a useful tool for their study and, along with formal and historic studies supplies enough elements to obtain a revalorization …
SHINING 3D EINSCAN-PRO, application and validation in the field of Cultural Heritage, from the Chillida-Leku Museum to the Archaeological Museum of Sarno
Abstract. The following contribution focuses on the low-cost Shining 3D EinScan-Pro scanner, above all the analysis of its precision and accuracy. The need to prove the functioning of this instrumentation in practical cases (the sculptures by Eduardo Chillida preserved in the Chillida-Leku Museum and along with some artefacts collected in the Archaeological Museum of Sarno), has led to the comparison and validation of the instrument through a methodology necessarily diversified from the guideline VDI/VDE 2634, part 2 and part 3, characteristics to the test the optical 3D measuring systems with planar measurement, which works according to the triangulation principle. In particular, two types…
Fotogrammetria e tecnologia IR per un rilievo digitale low-cost della scultura “Torso”, di Eduardo Chillida
The paper focuses on the analysis of ‘innovative’ technologies for low-cost survey: downstream test metrology and precise coding methodology, which could be of great support in the documen- tation, virtualization and dissemination of the sculptural heritage. The transposition of the museum works in 3D allows the return of models that can be used by remote –for studies, measurements, restorations, etc.–, no needing a physical contact with the piece, so in a non-invasive way. The virtual museum also offers the pos- sibility to organize exhibitions accessible to a wider audience.
ARCHITECTURAL SURVEY TECHNIQUES FOR DEGRADATION DIAGNOSTICS. AN APPLICATION FOR THE CULTURAL HERITAGE
Abstract. The great technological development in recent years in the field of architectural survey has made possible increasingly expeditious and less invasive investigations with the aim of acquiring a series of data related to the asset and fundamental for the protection of cultural heritage. In addition, the synergy between the various techniques represents an added value able, not only, to fill possible gaps and lacks arising from application limits of the instruments, but also to enhance the peculiarities of the same. This paper presents an integrated survey activity (range-based, image-based and IR thermography techniques) aimed at applying the combination and collaboration of multipl…
La Torre della Marina di Vietri sulla Costa d’Amalfi: test statistico-predittivi di dati fotogrammetrici
The Tower of Marina di Vietri on Amalfi Coast: a statistical-predictive test of photogrammetric dataThe focus of the work is on close-range photogrammetry and mainly on the low-cost technologies, experimented in the survey of Tower of Marina di Vietri, a historical building erected in the sixteenth century at Vietri sul Mare in the Province of Salerno. The general objective is to codify a methodology for objectifying the comparisons of the results; hence, the research starts from an original analysis conducted on the returned orthophotos by several photogrammetric paradigms. To estimate its reliability and precision, we proceeded, at first, with the extension and application of an error pro…
As-built graphic documentation of the Monumento a la Tolerancia. Validation of low-cost survey techniques
[EN] The Monumento a la Tolerancia is an emblematic sculpture realized by Eduardo Chillida, a perfect example for the documentation of sculptures with uniform textures, non-reflective colours and with poorly elaborated shapes through the implementation of various photogrammetric tools, as well as using different applications for processing phase. The basic data are photos taken quickly and without an accurate previous study, which is why the implementation of any target was not foreseen. In order to prove the results different kind of analysis were conducted. The first type was carried out analysing the results obtained from different software, with the use of the same instrument. The secon…
