摘要
随着"数字敦煌"的实施和推进,图像数字技术飞速发展,洞窟图像数字信息完整性进一步拓展。第254窟的狭小空间制约了立体面摄影采集,依据摄影数字技术和积累的经验,采用焦点堆栈技术有效解决了部分立体面摄影采集景深问题。焦点堆栈所采集的图像数据拼接完成后,需结合定位测量技术进行定位与纠正,最终实现符合数字敦煌档案的高品质数字图像。
With the implementation and advancement of ＂Digital Dunhuang,＂ the digital technology of the image has been developed rapidly and the complete digital information of the caves has been further enhanced. However, the narrow space of Cave 254 limits the photographic image acquisition of the 3D-Face. Drawing on digital photography technologies and our experience, applying focus stacking technology can effectively resolve the perspectives of photographical images of some 3D-Faces. After montaging the images collected by focus-stacking technology, it is necessary to use positioning measurement technology to fix and correct them so as to finally obtain high-quality digital images good enough for digital Dunhuang archives.
