Abstract

The objective of this work is to present a new practical approach to digital photogrammetry in artistic diagnosis and virtual restoration. The study has been applied to an anatomical model of polychrome wax, dated from the 18th century. In the photographic record, the combination of light sources (visible and ultraviolet) has been used to obtain 3D models that serve as documentation tools to accurately map the state of conservation and to project the virtual restoration. The stages of the photogrammetric process are described along with the lighting strategy and colour management used to solve the problem of virtual registration on surfaces of objects with very bright finishes. The results obtained are promising, because they make it possible to obtain a 3D model with optimal record of the morphology of the sculpture to project virtual solutions within the decision-making model.

光源在摄影测量模型中的应用，用于多色蜡中物体的诊断和虚拟恢复

本工作的目的是为数字摄影测量在艺术诊断和虚拟修复中提供一种新的实用方法。这项研究已应用于一个可追溯到18世纪的多色蜡解剖模型。在摄影记录中，光源（可见光和紫外线）的组合被用于获得3D模型，这些模型作为文件工具，可以准确地绘制保护状态图，并投影虚拟修复。描述了摄影测量过程的各个阶段，以及用于解决具有非常明亮饰面的物体表面虚拟配准问题的照明策略和颜色管理。所获得的结果是有希望的，因为它们使获得具有雕塑形态最佳记录的3D模型成为可能，从而在决策模型中投影虚拟解决方案。

期刊介绍： Conservar Património is a journal, published three times a year, that intends to create a space for the diffusion of conservator-restorers’ studies and activities. However, at a time when Conservation-Restoration pretends to develop further through collaboration with other areas of knowledge, such as History of Art, Archaeology, Museum Studies, Chemistry, Physics, Biology and other related disciplines from the fields of the natural and social sciences, the journal also receives contributions from any other provenance as long as directed towards the multiple dimensions of the works that integrate our Cultural Heritage. Theoretical issues on the conservation activity may also be submitted.
