Acquisition of Digital Photography Images of Murals Compensating for Curvature of the Wall Surfaces

WU Jian1,2,3 ZHANG Fan4 YU Tianxiu1,2,3 DING Xiaosheng1,2(1.Digitalization Center,Dunhuang Acadamy,Mogao Grottoes,Dunhuang,Gansu 736200;2.National Engineering Research Center for Conservation of Ancient Wall Paintings,Dunhuang,Gansu 736200;3.Zhejiang University,Hangzhou,Zhejiang 310013;4.State Key Laboratory of Information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,Wuhan,Hubei 430079)  
The surfaces of walls of the Mogao caves are not smooth.Confined to the current digital devices and methods,acquisition of digital mural images shows a series of problems,such as the perturbation from different photographing distance,uncertainties of image acquisition and integration plane,a certain angle between the image acquisition and integration plane,and the projection surface used for positioning and correct fitting.A three-dimensional model is used to acquire accurate curvature parameters of photographed walls and solve these problems,not only improving the quality and fidelity of panoramic images,but also standardizing the process of image acquisition.
