Abstract隨著"數字敦煌"的實施和推進,圖像數字技術飛速發展,洞窟圖像數字信息完整性進一步拓展。第254窟的狹小空間制約了立體面攝影采集,依據攝影數字技術和積累的經驗,采用焦點堆棧技術有效解決了部分立體面攝影采集景深問題。焦點堆棧所采集的圖像數據拼接完成后,需結合定位測量技術進行定位與糾正,最終實現符合數字敦煌檔案的高品質數字圖像。

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.
