敦煌莫高窟狹小空間內立體面攝影採集與圖像處理──以莫高窟第254窟數字化為例=Acquisition and Processing of the Photographic Images of the 3D Faces inside the Narrow Caves of the Mogao Grottoes——Taking the Digitization of the Mogao Cave 254 as an Example
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.
