Il rilievo delle sculture con tecniche laser scanner: uno strumento di conoscenza tra realtà virtuale e rigore scientifico

The evolution of Computer Technology has enabled rapid development and refinement of techniques for detection of solid objects, opening up interesting perspectives for applications in various fields. In recent years, mainly to satisfy certain requirements of the industrial sector have been introduced into the market laser scanner for object recognition. This type of instrument can detect millions of points in a few minutes with an accuracy satisfactory for many applications. The speed of data acquisition applied to cultural heritage can bring to the knowledge of heritage and its preservation with a considerable saving of time and costs, ensuring quality results. The current trend indicates that the laser scanner technology for mapping, modelling and 3D visualization is increasingly used in the field of cultural heritage. The scientific results of the survey and documentation of the collection, with the help of these techniques for the conservation, restoration and valorisation of cultural heritage, it is becoming increasingly sophisticated. On the other hand, reconstruction and virtual reality are increasingly seen as an effective tool for knowledge and heritage. The reconstruction and virtual reality provides an insight into the world through a kind of learning is direct rather than symbolic kind, through the mediation of writing and in some cases, may help further interaction even more depth. These technologies allow you to show a cultural object under all possible angles, rotate, manipulate, highlight details, etc.. Where is the limit in the documentation for the preservation and valorisation of cultural heritage between scientific rigor and stage effects? In this work, through some examples, developed in collaboration with various Public Institutions, we will analyze these two aspects in all their implications on some sculptures.
