摘　　要：敦煌壁画高保真数字化采集是其数字保护工作的重要基础。依据前期研究及自主研制的敦煌壁画色卡,对敦煌壁画高保真复制品数字采集工作中图像的色彩管理性能进行了研究,并与标准色卡Macbeth ColorChecker的色彩管理效果进行了主观对比评价。研究结果表明,相同拍摄条件下,自主研制的敦煌壁画色卡的色彩管理主观视觉评价结果优于标准色卡,且对于不同类型照明光源和不同偏色设定条件,自主研制的敦煌壁画色卡可以对偏色图像颜色进行有效校正。High-fidelity imaging is a key technique for digital protection of Dunhuang murals. Based on previous studies, we developed color charts and studied color management of digital imaging for Dunhuang murals. In terms of visual effects, our results show that the Dunhuang mural color charts we developed are superior to the standard Macbeth ColorChecker color charts based on subjective comparative evaluation under the same photo-shooting conditions. In addition, other results also show that the Dunhuang mural color charts can function well in color calibration under different illumination or color-bias conditions.
