On January 26th, 2018, Sara Gonizzi Barsanti finalized her Ph.D. in Mechanical Engineering at Politecnico di Milano, in the framework of the JPI CHT2 project. The methodology developed aims at optimizing procedures for 3D capturing ancient structures and objects with Computer Vision methods, to obtain 3D models with a level of complexity suitable for simulations with structural analysis. This allows analyzing structures that have been modified in time, whose addition can be more easily identified for their different mechanical properties. Such data, in addition to the reading of the wall surfaces, allows generating information useful for the diachronic evaluation of an object or a structure, finalized to its 4D modeling (3D + time).

Spanish-Italian meeting in Milan

During October a meeting between the Italian and Spanish partners took place at Politecnico di Milano to share experiences and results regarding the completion of their case studies. Several research lines and transfer of technology were discussed, being the critical issues:
(i) different alternatives of image-based modeling and multi-data fusion procedures;
(ii) mesh simplification and optimization to improve the results exportation, either for visualization or analysis purposes, as the stability of the CH asset;
(iii) reverse modeling techniques to give an added value to the final diachronic 3D models, taking into account object’s complexity and non-parametric modeling limitations;
(iv) the current state of advancement of the project deliverables.

The Italian partner has published findings on the Milan Roman Circus reconstruction in a special issue of Geosciences journal on “Remote sensing and geosciences for archaeology”. Entitled “Accurate Reconstruction of the Roman Circus in Milan by Georeferencing Heterogeneous Data Sources with GIS”, the paper can be viewed directly in Geosciences.
