全数字摄影测量技术在莫高窟崖面保护中的应用

随着计算机技术和测绘技术的不断发展,摄影测量发展到了全数字摄影测量阶段。作为摄影测量学的一门分支学科--近景摄影测量在建筑物的变形观测,动态监测、文物保护等工作中起着很重要的作用。通过对敦煌莫高窟崖面进行数字近景摄影测量,着重介绍利用全数字近景摄影测量技术获取大范围复杂地貌崖面的高精度立面地理空间数据的方法及在文物的维护、修复中的应用。

The Application of Full Digital Photographic Measuration Technique in the Protection of Dunhuang Mogao Grottoes

With the development of computer and surveying technology, Photogrammetry has run to Full Digital Photographic Measuration stage. As an embranchment of Photogrammetry, Close-range Photogrammetry plays a vital part in many aspects, for example the distortion observation, dynamic monitoring of buildings, and protection of cultural relics. This article emphasizes on introducing the methods for gaining high precision vertical surface geospace data of grottoes cliff with complicated physiognomy in large range and the application of Full Digital Photographic Measuration in cultural relics maintenance and rehabilitation through the project of digital Close-range Photogrammetry in Dunhuan Mogao grottoes cliff.
