Motivation

As part of this research project, the Great Mainz Jupiter Column is to be digitised in 3D in its condition after complete restoration. The Institute for Media Design will then digitally reconstruct the gaps in the figure decoration.

Based on the 3D data, haptic 3D models are to be created in various scales for different purposes, for example as tactile models for the blind and visually impaired in the exhibition of the State Museum or small models for sale in the museum shop.

The task of the i3mainz is the 3D data capture of the Jupiter column, which today still has a total height of 9.2 metres (the column was originally higher) and consists of eleven individual parts. The individual parts are not currently in the exhibition, but are stored in a museum magazine. Due to the environmental conditions with limited space and less than optimal lighting conditions, the measurement concept had to be adapted.

Activities

The eleven objects were evenly illuminated with four softboxes and photogrammetrically captured with the Nikon Z7II system camera. An image composite was recorded for each object, from which a textured 3D model was generated using the structure from motion method.

The 3D data will be completed in 2024 and visualised in a web viewer.
