摘　　要：提出了一种敦煌壁画颜料颜色数据库的构建方法:首先建立一套敦煌壁画的基础色标体系,对色标体系中每一个颜料色样的光谱、颜色、颗粒、物质属性进行量化标定,建立敦煌壁画色标体系基础数据库;然后结合"数字敦煌"项目的研究成果,针对已经数字化洞窟的影像数据进行精细分区编目,针对每个精细分区进行非接触式无损测量标定,获得每个精细分区的颜色、物理、化学属性等数据;最后建立每个精细分区和敦煌壁画色标体系基础数据库色样的映射关系,完成敦煌壁画颜料颜色数据的构建。This paper proposes a method for establishing a scientific pigment color database for the murals of Dunhuang consisting primarily of the following procedures： 1 ） To build a basic color system for pigments used at Dunhuang and to quantitatively and nondestructively calibrate each color sample of the color system, includ- ing spectra, color, particle size, and chemical constitution. 2） Based on the research results of the ＂Digital Dun- huang＂ project, to precisely segment and catalogue the image data of already digitized caves, and to nondestruc- tively calibrate each segment so as to obtain the data of each space, including color and physical and chemical properties. 3） To map out the relationship between each segment of the caves and the color samples from the basic color system database, thus connecting the first and second elements of this method to provide a clear picture of the location and color of pigments used in the murals of Dunhuang.
