多光谱摄影技术在印绘纺织品文物信息提取中的应用——以正德八年诰命为例

The use of multispectral photography technology to extract information from printed textiles——analysis of a piece of an imperial edict dated to the eighth year of the Ming Emperor,Zheng De

为了探讨多光谱摄影技术在纺织品文物信息无损提取中的实用性,利用多光谱成像系统和微型光谱仪对正德八年诰命中破损的纹理组织、模糊的墨书字迹进行识别。在对诰命的图像信息提取后发现,多光谱的红外光波段对纺织品文物上的墨书字迹具有较好的识别作用;在颜色复杂或肉眼无法识别细微纹理的情况下,结合提取对象的反射光谱,可以较好获取织物颜色和纹理信息,完善和补充纺织品文物的相关信息。多光谱摄影技术在纺织品文物信息无损分析方面具有较好的实用性。

Multispectral photography technology can be used as a nondestructive method to extract information from textiles. A multispectral imaging system and a micro spectrometer were used to identify and record the damaged textures and blurred ink writings on a piece of an imperial edict dated to eighth year of the Zheng De Emperor （Ming dynasty, 1513 AD）.It is found that the multiple wavelengthIR spectrum is very useful for identifying the ink writings. In combination with spectral analysis, the method could extract both textile color and texture information, especially when the textile colors are complicated and unidentifiable by the naked eye. The information soobtained could be used to complete and supplement the information on the textile relic. Multispectral photography is a practical and nondestructive method to extract information from ancient textiles.
