基于多角度倾斜影像的复杂建筑精细化重建应用

Application of complex building fine reconstruction based on multi-angle tilt image

在城市建设和自然变化等多种因素的叠加作用下,各类复杂多样、对历史研究具有重要意义的古建筑在损坏后因缺少资料而极难修复,因此,对其进行数字化保护,为后续修缮提供数据支撑意义重大。文章主要在倾斜摄影测量技术基础上,进行多角度影像间特征匹配能力分析,验证空中航线规划的倾斜摄影和自由航飞采集近景摄影测量结合的精细化三维重建方法可行性。

Under the superposition of various factors such as urban construction and natural change,it is extremely difficult to repair various complex and diverse ancient buildings of great significance to historical research due to lack of data after damage.Therefore,it is of great significance to carry out digital protection for them and provide data support for subsequent repair.Based on the tilt photogrammetry technology,this paper analyzes the feature matching ability between multi-angle images,and verifies the feasibility of the refined 3D reconstruction method combining the tilt photogrammetry of air route planning and the free-flight close-range photogrammetry.
