Laser Scanning Methodology for the Structural Modelling

Laser scanning methodology which has been used in different sectors, allow surveying an object by means of very dense and accurate point clouds acquisitions. The alignment and co-registration in a defined reference system allow generating a 3D model of the object, with the possibility to associate the radiometric information useful in many applications. In this paper, the operations in order to develop the three-dimensional models of the medieval town-walls of Padua and Cittadella (Padua) are described and analyzed. The accurate geometric information extracted was used in the structural analysis with the aim of the restoration: has been considered the just weight of the walls and the wind action to evaluate the planimetric distribution of structural tensions and to characterize the more critical areas.
