Amphorae modeling.



Amphorae Typology


Amphorae classification in archaeological work very strictly relies on dimension information for specific features of the object; for instance, the neck or belly. In providing a theoretical model for a specific amphora class, it makes sense to measure these features directly on available archaeological finds. In the case of amphorae, four measurable zones have been defined: heigth, width, rims, handle, belly and bottom. A series of simple geometric primitives are used to approximate these morphological characteristics and to act as an interface between the photogrammetric measurement and the underlying model.

Amphorae modeling methodology


This work made by Carlo Palmieri and Eleonora Simone is based on three-dimensional modeling, using appropriate software, of a series of amphorae found in the site of Malta under the supervision of Jean-Christophe Sourisseau for the archaeological context and Pierre Drap for the intergration in the photogrammetric measurment process.


amphora amphora

Our approach for the realization of the virtual models of amphora was based on three fundamental steps: the first step concerns the study of the photographic survey of the amphorae. From these photographs were extrapolated data for the recognition of amphorae, this recognition is tied to a an archive in which there is a list of amphorae found in various sites of the world with a detailed description; es: type of apoda, body, mouth, handle and trim . The purpose of the first step was to associate the amphora in the photo with the amphora in archive.


Analysis on the sur photos

Identified the object, in the second step, we proceeded with a virtual reconstruction; the object in archive is characterized by geometric features. On the basis of these values we virtually reconstructed the object with the software.




Three-dimensional modeling

The last step concerns a verification of congruence between the object created and the real object in the site. This check up is not always easy because we have some partial images of the object. The final model although these difficulties is qualitatively valid.
