Abstract

The aim of this work is to present an advancement in the technical protocol to obtain multiband 3D reconstructions of ancient statuary by photogrammetric acquisition of different input data as Visible (VIS), Ultraviolet Induced Visible Luminescence (UVL), and Visible Induced Luminescence (VIL). An acquisition workflow tailored for multiband photogrammetry was developed and tested on the Venus in a Bikini (INV 152798), belonging to MANN collection. The Bikini 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 multiband 3D reconstructions while remaining flexible and applicable in diverse operational scenarios.

The final multispectral 3D model, integrated into a Web3D framework (ATON), allows for interactive visualization, facilitating both scientific research and digital dissemination. It allows 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 multiband 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.

雕像多光谱三维重建的多波段摄影测量

这项工作的目的是通过摄影测量获取不同的输入数据，如可见光（VIS），紫外线诱导可见发光（UVL）和可见诱导发光（VIL），来获得古代雕像的多波段三维重建技术方案的进展。为多波段摄影测量量身定制的采集工作流程在MANN系列的维纳斯比基尼号（INV 152798）上进行了开发和测试。比基尼雕像保留了原始多色的丰富遗迹，特别是在strophyon（一种泳衣）和凉鞋上的镀金，以及树干支撑和披风上的粉红色痕迹。与其他工作流程相比，该工作流程旨在生成多波段3D重建，同时保持灵活性，适用于各种操作场景。最终的多光谱3D模型集成到Web3D框架（ATON）中，允许交互式可视化，促进科学研究和数字传播。它允许以高分辨率同时探索整个雕塑的形态特征，结合那些肉眼不可见但由多波段采集揭示的属性的详细信息。外推的观察结果主要涉及保守干预表面的存在，或者可以突出的特殊颜料和图案装饰。
