摘要
随着无人机技术的日益成熟,倾斜摄影测量数据可有效支撑实景三维展示。消费级无人机具有快速、灵活、高性价比等显著优势,受到广泛关注。然而有关该类无人机室内场景倾斜摄影测量的研究较少。本文开展了基于消费级无人机的室内倾斜摄影三维建模研究。在无GPS辅助情况下,通过少量地面控制点,应用ContextCapture软件,将航摄像片数据经过空三加密、自动建模、贴图等操作后,快速构建出室内实体三维模型。结合对生成模型3MX格式文件的代码分析和编辑,实现了多模型的定位和组合。通过某室内试验大厅的实例验证了该方法的可行性,为消费级无人机在室内实景三维建设方面应用提供了技术参考。
With the maturity of UAV technology,tilt photogrammetric data can effectively support real-world 3D display.Consumer UAV attracted wide attention with rapid,flexible,and cost-effective advantages,but there are few studies on relevant applications of indoor real 3D model building.This paper carried out a research on indoor 3D modeling of oblique photogrammetry based on consumer UAV.With a small number of ground control points without GPS assistance,the ContextCapture software is used to model the building entity after the aerial camera data is encrypted,automatically modeled,mapped and other operations.Combined with code analysis and editing of 3MX format files for the generated model,the positioning and combination of multiple models was achieved.A practical example of indoor testing hall shows that the method is feasible,and it serves as a technical reference for relevant applications of indoor real-world 3D construction.
