Photogrammetry allows the three-dimensional reconstruction (3D) of an item, for example a place, a building, or an object like a statue, for purposes of inventory, monitoring, tracking, analyzing … all this from photographs. In the field of heritage and archeology, availability of imagery makes possible the restoration works of art or historical buildings in an digital format accessible everywhere by everyone. The resulting data is a source of information of great value because it makes the analysis, measurement and visualization possible while preserving the object from any manipulation that may cause damage.
Augmented reality allows us to go even further in the exploitation of this technology by immersing us in a world virtually reconstructed. Thus you can walk among medieval ruins, tablet in hand, and watch in real time the hall of an ancient castle, rebuilt from images, historical documents and plans.
