The photogrammetric technique is also used in similar fields, such as paleontology or geoarchaeology. Over the last few years, numerous approaches have been based on the use of photogrammetry for the acquisition of artifacts and architectural structures both with field applications, as in the case of Catalhoyuk, and through the use of drones for overall environmental acquisitions. The objective of this contribution is the presentation of an acquisition methodology in the field of cultural heritage that is independent of the use of specific tools or software and compliant with the methods adopted by researchers in humanities and computer science. A long-term aim is a methodological approach for different endeavors of cultural heritage. As a proof of concept, we show how a preliminary release of the workflow has been applied in the context of the BeArchaeo project, for the acquisition, processing, export, modeling, archiving, and indexing of 3D models, resulting from photogrammetric surveys. We describe the general functions and processes and how they can be implemented in a practical workflow. The general approach relies on the digital data curation framework for cultural heritage and encompasses several specialized tasks. This paper aims at proposing an approach for a shared 3D survey workflow for photogrammetry in archaeology. To date, we still lack a shared method for a photogrammetric survey that derives from the specific design and techniques/contexts.
In most cases, the pipeline is the result of empirical experimentation and is designed to act within the specific context of the project.
Each project has developed its work pipeline for raw data acquisition and the elaboration of models and their archiving and dissemination. Consequently, archaeological datasets have been enriched with 3D models of archaeological finds and structures. The technological advancement of software and hardware and the lowering of the prices of instrumentation has made photogrammetry the preferred instrument for surveying activities in archaeological projects.
