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).
The Hadrian’s Wall case study took a step forward today when the British weather finally allowed the UK team to undertake an UAV survey at Beckfoot, Cumbria. A Quest300 fixed-wing UAV (pictured), owned by Newcastle University, was used for the survey. With a maximum 15-minute flight time, the Beckfoot area was divided into two overlapping parts (north and south) and surveyed under two separate sorties. Supporting ground operations took place simultaneously and the survey data will be augmented by archaeological excavations and geophysical survey, including gradiometry and resistivity, surveys previously conducted in June.
