摘　　要：古代壁画作为中国众多文化遗产中重要的一部分,经过时间的洗礼,出现了褪色、脱落、空鼓等各种安全问题,亟须对其进行保护修复。壁画的颜料成分组成是修复的重要因素,之前学者们对壁画颜料的技术手段主要停留在采样分析或者局部分析上,不能保证文物的安全及信息的完整性。本文采用非接触无损的高光谱技术,以云冈石窟第5窟壁画为研究对象,分别获取并分析壁画的点状光谱与高光谱成像数据,完成了整幅壁画表面颜料种类的识别和空间分布的可视化,实现了颜料信息的数字化存档,充实了中国清代壁画的颜料库,为壁画的修复和色彩复原提供了科学依据。As an important part of many cultural heritages in China,the ancient frescoes have appeared various safety problems such as fading,falling off,and empty drum after the baptism of time,which is in urgent need of protection and restoration.The pigment composition of mural paintings is an important factor in the restoration of mural paintings.Before,the technical means of scholars mainly stayed in sampling analysis or local analysis,which could not guarantee the safety of cultural relics and the integrity of information.This paper adopts non-contact and non-destructive hyperspectral technology,takes the mural paintings in Cave 5 of Yungang Grottoes as the research object,obtains and analyzes the dot spectrum and hyperspectral imaging data of the mural paintings respectively,completes the identification of pigment types on the surface of the whole mural and visualizes the spatial distribution,realizes the digital archiving of pigment information,and enriches the pigment library of Chinese mural paintings in Qing Dynasty.It provides scientific basis for restoration and color restoration of mural paintings.
