Laser Scanner 3D per la catalogazione dell’Architettura Medioevale: la chiesa di Santa Croce in Bergamo

The improvement of new active optical sensors has revolutionized the survey method for cultural heritage. The conservation and enhancement of heritage require an extensive documentation both in terms of shape, color and geometry and of more properly historical-artistic features and the incessant development of scientific research today provides new possibilities and tools which is essential to know and use, in the framework of a responsible and conscious research experimentation. In the field of archeology, the automatic 3D survey is now recognized as an "added value" compared to traditional practices and the active contribution that this technology can provide to the interpretative phase, cataloguing and promotion of archeological assets, even through the web, is becoming increasingly clear. On the other hand, even considering the speed of the procedure and the measurement accuracy, there have been calls for reflection on the role that laser scanning can play in the world of archeology. Role that it is appropriate to clarify and positively consolidate even by conducting new studies and experiments, such as the one here presented and concerning the Church of Santa Croce in Bergamo, а small octagonal Romanesque chapel built іn the fіrst half оf the 11th century.
