Over the last few decades a significant effort has been put on the development of detailed numerical models to predict the mechanical behavior of historical masonry. However, an issue faced in the numerical modelling of historic and damaged masonry structures is the development of accurate models to represent their real geometries. This paper presents the first stage of a research program which aims to develop an automatic approach which uses point clouds to generate the detailed geometry of masonry. Such geometry can then be inputted into micro-models for the structural analysis of masonry structures. In the proposed approach, point clouds generated using the Structure-from-Motion (SfM) pipeline were converted into watertight meshes and then voxelized. Models were represented as a sum of cuboid-blocks jointed by zero thickness interfaces. The developed methodology was applied to derive geometries of two small scale masonry specimens constructed in the laboratory and a full-scale masonry arch bridge.
