Abstract

The most recent computer technologies of 3D geometrical modelling provide a great quantity of tools for archaeological investigation. This paper presents an application of the 3D laser scanner to study the metric and morphometric parameters of a Chalcolithic pottery vessel based on a 3D meshed triangular model. This model is referenced geometrically by high-precision fitting to the real object, enabling the study of some of the most important archaeological characteristics with great accuracy (texture, damage, profiles, etc.) as well as a reconstruction of those damaged parts. The computerized model has been used to study the metric and geometric parameters of the vessel, applying different statistical tests to analyse the width of vessel and the variability of some constructive parameters. These analyses allow us to compute any measurement, such as the surface area of vessel, the center of masses, the volume, and the regularly spaced contour levels of the interior and exterior. The results indicate the skill of the potters of the Copper Age and their knowledge of some elementary mathematical concepts of geometry and metric.
