Multiband photogrammetry for multispectral 3D reconstruction of statuary
Year: 2025
Type: article
Abstract: The aim of this work is to present an advancement in the technical protocol to obtain multi-spectral 3D reconstructions of ancient statuary by photogrammetric acquisition of different input data as visible, ultraviolet induced luminescence and visible induced luminescence images. An acquisition workflow tailored for multiband photogrammetry was developed and tested on the Bikini Venus (INV 152798), belonging to MANN collection. The Bikini Venus statue preserves rich remnants of the original polychromy, and in particular gilding on the strophyon (a sort of swimming suit) and on the sandals and pink traces on the tree trunk support and the draped cloak. The workflow, in comparison to others, is designed to generate multi-spectral 3D reconstructions while remaining flexible and adaptable for use in various conditions, imaging technologies, and with complex objects. The generated RGB, Visible-induced Luminescence (VIL) and Ultraviolet-induced Visible Luminescence (UVL) 3D models of the artifact make it possible, through the use of a visualizer, to simultaneously explore morphological characteristics on the entire sculpture at high resolution, combining detailed information on those properties not visible to the naked eye, but revealed by the multi-band acquisitions The extrapolated observations relate mainly to the presence on the surface of conservative intervention, or peculiar pigments and pattern decoration that can be highlighted.
