Abstract

Historical and architectural heritage assets are continuously exposed to a high risk of damage caused not only by natural events but also by poor maintenance or neglect. In order to preserve these structures, it is necessary to carry out a series of multi-level studies that provide a high level of support to all professionals working in this field. The use of appropriate geomatic techniques and instrumentation based on digital acquisition allow for the elaboration of accurate and high-performance 3D models in the various fields of study. This manuscript illustrates a methodology that, starting from the TLS survey of an architectural structure in a Romanian village, has allowed the elaboration of an accurate 3D model which was optimised and transformed into a polygonal mesh model (quad-mesh). This model representing an accurate input data in the subsequent H-FEM (Heritage Finite Element Model) analysis process.
