高光谱成像技术在故宫书画文物保护中的应用

为探讨对故宫书画文物进行整体分析、保护的方法,本研究利用研发的高光谱成像系统,对故宫博物院的部分馆藏书画文物进行分析。分析发现,高光谱成像技术在文字信息增强、隐藏信息提取、底稿线提取、颜料分析等方面有独特的优势。将高光谱成像技术用于书画文物的保护,不仅能够深度了解文物病害程度,为绘画工艺研究提供帮助,更重要的是能够为书画文物的保护修复材料选择和修复效果评估提供参考,使保护修复更加全面和科学化,同时能缩短病害调查和科学分析的时间,加快保护修复工作的进度。

Hyperspectral imaging to Chinese paintings at the Palace Museum

Hyperspectral imaging technology is an efficient and nondestructive technique to study ancient Chinese paintings. The method is not affected by test objects and environment. A hyperspectral imaging system to scan and analyze some paintings in the Palace Museum was developed. It is found that this method has unique advantages in studies of text information enhancement, extraction of hidden information,extraction of line features from drawings, and that it benefits identification of colors and classification of paintings. The number of ancient paintings is very large in the Palace Museum.These paintings need to be well conserved and restored. Hyperspectral imaging technology can be applied in Chinese paintings conservation. It provides a safe and effective approach for scientific analysis and conservation.
