Abstract受莫高窟壁面的不平整性、目前壁畫數字化采集的設備與方法等制約,壁畫數字化攝影采集方法中存在著攝距差異、攝影采集集成平面的不確定性和攝影采集集成平面與定位糾正擬合的正射投影面存在一定的夾角等問題。本文針對這些問題,提出了利用三維模型獲得攝影采集壁面準確的曲率參數為依據,解決了目前攝影采集中存在的問題,提高了高保真全景圖像的質量,使攝影采集進一步規范化與標準化。

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.
