摘　　要：实景三维中国要求部分区域航摄影像分辨率优于2 cm,城市由于高楼的存在,采用传统固定航高获取的影像,有些区域难以满足2 cm分辨率的要求。针对这个问题,本文对无人机航摄原理深入研究后,提出采用仿地飞行的方式获取倾斜摄影影像,既可以保证航摄的安全性,又可以获取满足要求的影像。通过实际项目验证得出:采用无人机仿地倾斜摄影技术生产的模型表征质量更好,模型精度更高,对城市实景三维模型的建立具有重要意义。This paper points out that real scene 3D China requires the resolution of aerial photography in some areas is better than 2 cm.However,due to the existence of tall buildings in cities,it is difficult to meet the requirement of 2 cm resolution in some areas by using traditional fixed aerial height.In order to solve this problem,this paper studies the principle of UAV aerial photography deeply,and proposes the method of imitation ground flight to obtain oblique photographic images,which can not only ensure the safety of aerial photography,but also obtain images that meet the requirements.Through the actual project verification,it can be concluded that the scheme in this paper can produce better model representation quality and higher model precision,which can bring reference to the production of urban real scene 3D models.
