摘　　要：针对在大高差环境下,高差航摄序列影像空中三角测量效果差、异形建筑精细化模型建模难的问题,以大学生活动中心异形建筑为研究对象,提出一种融合大高差影像序列的单体异形建筑免像控建模方法。探讨了在同一高空处多环交叉环拍航摄与五架次航摄的效率和精度对比,验证了多环交叉环拍方案更高效可行;采用了“多环交叉环拍、弓形贴面环拍为主,公共接边过渡影像为辅”的航摄影像采集方案,融合了大高差序列影像,并完成单体异形建筑的实景三维模型重建。该方法重建的异形建筑三维模型纹理清晰、精度高,为大高差环境的城市建筑精细化三维模型提供有效方案,可顺应城市信息模型(city information modeling,CIM)基础平台建设发展。Aiming at the problem of poor aerial triangulation effect of aerial photography sequence images in large altitude difference environment,and the difficulty of modeling special-shaped buildings in fine-shaped buildings,this research takes the university student activity center special-shaped buildings as the research object and proposes a fusion of large altitude difference image sequence-based modeling method for single-shaped and special-shaped buildings without image control.The efficiency and accuracy comparison between multi-loop cross-loop aerial photography and five aerial photography at the same high altitude is discussed,and it is verified that the multi-loop cross-loop photography scheme is more efficient and feasible;the use of“multi-loop cross-loop photography,bow-shaped veneer photography”and the aerial photographic image acquisition program of"mainly,public border transitional image supplemented"integrate large height difference sequence images,and complete the reconstruction of the real three-dimensional model of the single-shaped building.The 3D model of special-shaped buildings reconstructed by this method has clear texture and high accuracy.It provides an effective solution for the refined 3D model of urban buildings in a large height difference environment,and can conform to the development of the urban information model(CIM)infrastructure platform.
