摘要

高光谱成像技术在文物调查领域的应用正在迅速发展。在这项研究中，短波长红外高光谱成像(960-2500 nm)已被探索作为一种潜在的非侵入性技术，用于青铜雕塑腐蚀产物的原位测绘。研究人员考虑了两种腐蚀产物，常在室外青铜纪念碑表面发现的铁榴石和铁榴石。在奥斯陆奥古斯特·罗丹的青铜雕塑《拿钥匙的人》的表面上研究了它们的空间分布。结果表明，结合图像分析算法的高光谱成像可以显示出两种腐蚀产物在雕塑不同区域(未遮挡和部分遮挡)的分布。

Can hyperspectral imaging be used to map corrosion products on outdoor bronze sculptures?

The application of hyperspectral imaging in the field of cultural heritage investigation is growing rapidly. In this study, short wavelength infrared hyperspectral imaging (960–2500 nm) has been explored as a potential non-invasive technique for in situ mapping of corrosion products on bronze sculptures. Two corrosion products, brochantite and antlerite, commonly found on the surfaces of outdoor bronze monuments, were considered. Their spatial distribution was investigated on the surface of the bronze sculpture The Man with the Key by Auguste Rodin in Oslo. The results demonstrate that hyperspectral imaging combined with image analysis algorithms can display the distribution of the two corrosion products in different areas (unsheltered and partially sheltered) of the sculpture.

期刊介绍： JSI—Journal of Spectral Imaging is the first journal to bring together current research from the diverse research areas of spectral, hyperspectral and chemical imaging as well as related areas such as remote sensing, chemometrics, data mining and data handling for spectral image data. We believe all those working in Spectral Imaging can benefit from the knowledge of others even in widely different fields. We welcome original research papers, letters, review articles, tutorial papers, short communications and technical notes.
