摘　　要：无人机上搭载多镜头倾斜数码相机或单镜头旋转相机,能从不同角度获取露天石雕的倾斜影像,能快速、高效、低成本建立目标的实景三维模型,但是由于石窟雕塑一般嵌于岩体内部,仅仅依靠无人机立面影像数据还无法建立石窟精细化实景三维模型。本文通过普通相机拍摄一定数量石窟内部数据,将无人机立面影像数据与普通相机辅助下细节特征数据融合,真实还原了石窟遗址内外部真实场景,为石窟的修复保护工程提供基础数据。研究结果对文保部门建立文化遗产基础地理信息数据库以及提供三维基础数据具有重要参考价值。Unmanned Aerial Vehicle(UAV)equipped with multi-lens oblique digital camera or single lens rotating camera can collect oblique images of open-air stone sculptures from different angles,which can build realistic 3D model of the object quickly,efficiently and economically.Because the grotto sculptures generally embedded within the rock mass,unmanned aerial vehicle(UAV)facade image data cannot establish grotto refined 3D model completely.In this paper,by shooting a certain number of ordinary camera data inside the grottoes,the facade image data of the UAV and the detailed feature data assisted by the ordinary camera are fused to truly restore the real scenes inside and outside the grottoes,so as to provide basic data for the restoration and protection of grottoes.The results of this study have important reference value for the establishment of basic geographic information database of cultural heritage and the support of three-dimensional basic data for cultural protection departments.
