【摘要】：受莫高窟壁面的不平整性、目前壁画数字化采集的设备与方法等制约,壁画数字化摄影采集方法中存在着摄距差异、摄影采集集成平面的不确定性和摄影采集集成平面与定位纠正拟合的正射投影面存在一定的夹角等问题。本文针对这些问题,提出了利用三维模型获得摄影采集壁面准确的曲率参数为依据,解决了目前摄影采集中存在的问题,提高了高保真全景图像的质量,使摄影采集进一步规范化与标准化。
[Abstract]:Restricted by the uneven surface of the wall of Mogao Grottoes and the equipment and methods of digital collection of murals at present, there is a difference in the shooting distance in the methods of collecting digital photographs of murals. There are some problems in the uncertainty of the integrated plane of photographic acquisition and the angle between the integrated plane of photographic acquisition and the orthographic projection plane fitted by positioning correction. In order to solve these problems, a 3D model is proposed to obtain the accurate curvature parameters of the photographic collection wall, which solves the existing problems and improves the quality of the high fidelity panoramic image. Make photography collection further standardization and standardization.
