摘要
为提高无人机三维成果在仿古建筑重建领域应用效率,以桂林雁山园博园景区为研究区,利用无人机倾斜摄影测量获取航片数据及RTK采集影像配准及检核数据,通过ContextCapture对倾斜摄影测量原始数据进行空三解算、三维重建等操作得到具有真实纹理的实景三维模型,进行模型平面及高程精度验证后,使用DP-Modeler合理修复场景,同时量测仿古建筑的建筑结构比例,将结果用于SketchUp和3ds Max进行景区内大雁阁典型仿古建筑单体化精细建模,分别得到其单体化精细模型。通过分析其细部结构重建效果以及单体精细重建效果发现,本文方法在可视化效果优于传统倾斜摄影三维重建效果的同时,SketchUp进行仿古建筑建模效率优于3ds Max;且相同可视化效果的条件下,SketchUp比3ds Max的工程文件大小大2.09倍,图元数量多9.66%,模型TIN数量多72.97%。
The application efficiency of UAV 3D in the field of antique building reconstruction is focused on.Guilin scenic area of Yanshan garden show park is taken as the research area.UAV tilt photogrammetry is used for aerial photo and RTK for data acquisition of image registration and check data.The real 3D model with real texture is obtained by ContextCapture performing,aerial triangulation,3D reconstruction and other operations on the original data of oblique photogrammetry.After verifying the model plane and elevation accuracy,DP-Modeler is used to reasonably repair the scene and measure the architectural proportions of the antique buildings.The results are applied to SketchUp and 3ds Max for detailed modeling of typical archaized buildings in the scenic area of Dayan Pavilion,and the detailed modeling of the monolized buildings is obtained respectively.In analysis the detailed structure reconstruction and individual fine reconstruction,it is found that the visualization this method is better than that of traditional tilting 3D reconstruction,and SketchUps modeling efficiency is better than 3ds Max in modeling the archaized buildings.With the same visualizations,SketchUp is 2.09 times larger than 3ds Max project files,with 9.66%more pixels,and 72.97%more model TIN.It provides a new idea for the visualization of archaized architecture.
