Use of photogrammetric techniques for virtual modeling of historical heritage. Application: Santa Bárbara Bridge (Almería, Spain).

Abstract

Photogrammetry using images from unmanned aerial vehicles (UAV) has revolutionized the conservation and dissemination of heritage, being increasingly used to document and preserve buildings of historical and cultural value, allowing a moment in time to be preserved for posterity. The aim of this study is the virtual reconstruction of the Santa Bárbara Bridge (Huércal Overa, Almería). For this purpose, two techniques was combined: on the one hand, photogrammetric techniques to carry out a survey of the current state, and on the other hand, architectural modeling software to reproduce the original state of the bridge. Complementarily, it has been essential to collect historical information that allows us to adjust to the reality built in its day.
