Three-Dimensional Virtual Models for Better Comprehension of Architectural Heritage Construction Techniques and Its Maintenance over Time

摘要

The paper discusses the use of innovative surveying technologies and modelling techniques not only in terms of digitalization and documentation of cultural architectonic heritage but in function of management and monitoring of buildings and their behaviour over time. The final aim is to identify elements that can contribute to elaborate a shared methodology for 3D content model generation. High precision survey (Terrestrial Laser Scanner, Photogrammetry, Multispectral data integration) was used for the investigation of several vault structures in order to carry out maintenance and structural stability analysis, in support to the comprehension of the behaviour of architectural elements within the whole building organism. Object Content Model and the logic of Building Information Models (BIM) have opened interesting scenarios to be investigated, with a possible large contribution of virtual models to the monitoring and to the life cycle management within the overall framework of planned conservation for architectural heritage.
