La tridimensionalidad del registro arqueológico. Uso de técnicas Structure From Motion (SfM) en el proyecto MEMOLA

You are here


Ever since the project design to the site of El Jarafi (Lanteira, Granada – Spain) was laid out, the photogrammetry 3D was defined as the method of registration, followed by the methodology established within the project MEMOLA. This dynamic affected both the fieldwork as the processing of data in the laboratory, as well as overcoming completely the photogrammetry 2D. The results obtained with the use of these tools also enabled their combination with the SIG, creating databases in which the alphanumeric and the geometric information appear related. These kinds of techniques provide a reduction of the economic cost, along with minimizing the time spent in the large-scale data acquisition, greatly reducing the space used for this type of work when applying traditional techniques. In relation to these procedures emerge a series of new issues. In this sense, the synchronization of the alphanumeric and the 3D geometric information remain one of the principal problems to be solved, although one of the goals of the experience with this site is to settle these kinds of frictions by refining the process. Likewise, the great volume of data recovered requires an additional effort of monitoring and selecting the information that we will ultimately work with. This process is not limited to an exclusively scientific documentation, but in addition, has great potential within diffusion, offering a more intuitive presentation; an aspect of great relevance when democratizing the results of a research.
