Crowdsourcing Cultural Heritage: From 3D Modeling to the Engagement of Young Generations

Monitoring, digitizing and archiving museum artworks represent an important socio-cultural accomplishment and an overcoming in digital preservation today. Cultural heritage is constantly under threat of terrorist attacks and natural disaster. The high costs related to documentation task have prevented a constantly and massive survey activity. The low cost 3D image based acquisition and elaboration techniques of an object, allow to carry out a 3D photorealistic model in a short time. Therefore, a lot of museum adopted these techniques for the artworks archiving. Crowdsourcing activities can significantly speed up survey and elaboration procedures. If, on the one hand, these initiatives can have a positive impact, on the other hand involve the online user with a marginal role. In this paper we demonstrate how it is appropriate thinking the museum visitor as “museum operator/maker” of the digital model overstepping the outcomes achieved so far.

Low cost handheld 3D scanning for architectural elements acquisition

3D scanning has gone a long way since its first appearance in cultural heritage digitization and modeling. In the recent years some new low cost, fast, accurate emerging technologies are flooding the market. Envisioning the massive use of these cheap and easy to use devices in the next years, it is crucial to explore the possible fields of application and to test their effectiveness in terms of easiness of 3D data collection, processing, mesh resolution and metric accuracy against the size and features of the objects. In this study we focus the attention on one emerging technology, the Structure Sensor device, in order to verify a 3D pipeline acquisition on an architectural element and its details. The methodological approach is thought to define a pipeline of 3D acquisition exploiting low cost and open source technologies and foresees the assessment of this procedure in comparison with data obtained by a Time of Flight device.

Environmentally Assessing Buildings Characterized by Complex Shape and Innovative Materials

This paper addresses the emerging problem consisting in a correct energy and environmental evaluation of buildings belonging to the new architectural tendency. In fact, innovative buildings are often characterized by new materials that, not rarely, are not contemplated in current environmental databases. Moreover, unconventional shapes of these buildings could require further manufacturing processes that involve additional energy consumption not included in the commercial environmental database. Through the work a spotlighting of the problem is presented with reference to a real innovative building.

Architectural perspectives in the cathedral of Palermo : image-based modeling for cultural heritage understanding and enhancement

Palermo offers a repertoire of both artistic and architectural solid perspective of great beauty and in large quantity. This paper addresses the problem of the 3D survey of these works and their related study through the use of image-based modelling (IBM) techniques. We propose, as case studies, the use of IBM techniques inside the Cathedral of Palermo. Indeed, the church houses a huge and rich sculptural repertoire, dating back to 16 century, which constitutes a valid field of IBM techniques application. The aim of this study is to demonstrate the effectiveness and potentiality of these techniques for geometric analysis of sculptured works. Indeed, usually the survey of these artworks is very difficult due the geometric complexity, typical of sculptured elements. In this study, we analysed cylindrical and planar geometries as well as carrying out an application of perspective return.
