UAV archaeological reconstruction: The study case of Chamartin Hillfort (Avila, Spain)

Photogrammetry from unmanned aerial vehicles (UAV) is a common technique for 3D modelling in a low-cost way. This technique is becoming essential to analyse the cultural heritage, e.g. historical buildings, monuments and archaeological remains in order not only to preserve them, but for disseminate accurate graphic information. The study case of Chamartin hillfort (Avila, Spain) provided us the opportunity to apply automation techniques to generate geomatic products with high metric quality. A novel photogrammetric software tool was used with the aim to achieve high resolution orthophoto and 3D models of complex sites. This tool allows a flexible way for heritage documentation, since it incorporates robust algorithms to cope with a wide range of studies cases and shooting configurations.
