Medieval towers in Tarragona
Photogrammetric techniques are very useful for three-dimensional modelling or for obtaining graphical scale mapping. For the project we carried out for the University of Barcelona, we used techniques to catalogue and study the various medieval structures.
These structures are various medieval watch towers. Due to the complexity and size, we used a photogrammetric drone capture system. By means of its calibrated cameras and specialised software, very complete information of the geometry and the current state of the towers is obtained, allowing historians to determine the construction phases during various centenaries.
