Photogrammetry and macro photography. The experience of the MUSINT II Project in the 3D digitizing process of small size archaeological artifacts

Main Article Content
Abstract
The MUSINT II project was created to publicize and promote the Minoan glyptic, a little-known archaeological heritage. Its contents were designed to involve both specialists and a general public (adults and children).
The project focuses on the 3D digitalization of seventeen very small (about 15mm diameter) seals, stored in the archives of the National Archaeological Museum of Florence.
The digitalization of these artifacts required a high-quality resolution technique capable of capturing their morphology and decorative motives and, at the same time, appeal to the educational targets.
For this reason, the Structure from Motion (SfM) Photogrammetry was chosen. This technology makes it possible to obtain three-dimensional reproductions from random photographs made by non-dedicated devices, but the tiny-object survey required specific instruments and skills.
A macrophotography technique was applied together with a specific workflow to obtain high quality photogrammetric models and to save time in acquiring and processing images. With this methodology, 3D models of high metric precision mesh and maximum color fidelity textures were obtained. This process delivers results of high level detail for low capital costs and minimal acquisition and processing time.Downloads
