摘　　要：墓葬壁画是重要的文化遗产,在墓葬现场干预之前,通过数字化方式第一时间将壁画颜色信息准确而有效地记录下来是十分迫切和必要的,然而图像颜色的高保真再现问题一直是制约墓葬壁画精确数字档案建立的关键问题。本研究以西安交通大学西汉壁画墓为例,对全封闭墓葬壁画在单一光源下所采集的壁画图像在颜色校正过程中的难点和关键技术进行了分析,针对墓葬壁画采集条件限制,采集图像质量不高等导致的壁画图像颜色校正精度低的问题,提出了基于三维查找表算法的完整颜色校正解决方案,试验证明本研究提出的方法提升了颜色校正的精度,有效地避免主观及环境因素对于墓葬壁画颜色数据的干扰,对墓葬壁画等文化遗产的保存、保护、研究、利用都具有重要的理论意义和实际应用价值,并对文物数字化普遍存在的颜色问题具有一定的借鉴意义。Tomb murals are an important part of cultural heritage in China.It is very urgent and necessary to record the color information of murals accurately and effectively by digital measures in the first place before the intervention of a tomb site.However,due to the deviation of the output frequency(color)of the light source and the characteristics of the photosensitive elements(CCD camera,etc.)used in the image acquisition system,the problem of high-fidelity reproduction of image colors has always been a key factor restricting the establishment of accurate digital archives of tomb murals.With the aim of solving this problem,the Western Han mural tomb at Xi’an Jiaotong University was used as an example to discuss the difficulties and key technologies in the process of color correction of the mural images collected from the fully enclosed tomb murals under a single light source.In view of the low accuracy of color correction of mural images caused by the limited collection conditions of tomb murals and the low quality of collected images,a complete color correction solution based on the 3D-look-up table algorithm is proposed.The trials show that the method improved the accuracy of color correction.This study duplicated the original features of murals with a high-resolution and high-fidelity result,which makes sense to the conservation,sharing,research and utilization of tomb murals and other cultural heritage objects.
