Aplicación de tecnologías 3D en sitios arqueológicos del valle de Ongamira, Córdoba, Argentina. Fotogrametría en excavaciones y morteros arqueológicos

Abstract

A contribution is presented for the application of new digital technologies within archaeological studies. In order to achieve this, virtual models were generated of mortars located in different places and on stratigraphic excavations in open air sites and rockshelters from surveying data collected in the Ongamira valley. Using the technique of photogrammetry, the record of 3 rock shelters with evidence of occupation was carried out, along with 8 excavation units and 5 mortars, of which 4 were mobile and one was in the base rock. The application of this technique requires taking pictures systematically at different angles. After photographing the entire object or feature, a digital model was made using the VisualSFM and Meshlab programs. The result of this was a three-dimensional virtual model in which it allowed us to understand the structure of the original object and its characteristics. With the use of these tools we hope to contribute to the development of digital techniques for the revaluation, record, conservation and dissemination of places with evidence of human activities in the past.
