Abstract
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
