A reliable survey of the building geometry is a basic tool for the knowledge of the structure and the correct setting of numerical computational models. An accurate procedure of the method was applied to the build of the 3D model of church of San Nicola Montedoro in Martina Franca (Italy).

In this way, it was possible to obtain an accurate and detailed geometric point cloud of the object. Subsequently, the 3D mesh model was generated from the point clouds. An adequate procedure of simplification and regularization of the meshes allowed to export and subsequently to import them into BIM (Building Information Modeling) software and structural analysis.

Abstract
A reliable survey of the building geometry is a basic tool for the knowledge of the structure and the correct setting of numerical computational models. An accurate procedure of the method was applied to the build of the 3D model of church of San Nicola Montedoro in Martina Franca (Italy). In this case study, the survey of the church was performed using integrated geomatics techniques: TLS (Terrestrial Laser Scanner), terrestrial and UAV (Unmanned Aerial Vehicle) photogrammetry. In this way, it was possible to obtain an accurate and detailed geometric point cloud of the object. Subsequently, the 3D mesh model was generated from the point clouds. An adequate procedure of simplification and regularization of the meshes allowed to export and subsequently to import them into BIM (Building Information Modeling) software and structural analysis. In addition, a suitable procedure was implemented to produce a model based on Finite Element Method from a simplified model of polysurface mesh, which allowed quantifying the distortions of the building, through the knowledge of the details of each element, becoming the basis for subsequent analysis of the same.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
