无人机倾斜摄影在土地调查中的应用

Application of UAV Oblique Photography in Land Survey

【目的】在我国土地调查发展过程中,常因技术手段存在缺陷,导致调查工作受到一定的影响。利用无人机倾斜摄影技术来建立实景三维模型,通过三维模型来完成相关调查工作,使土地调查工作更加高效、便捷。【方法】为探讨无人机倾斜摄影技术在土地调查工作中的应用优势,使用无人机搭载单目相机来采集影像,利用ContextCapture Center软件进行三维建模,并与实际调查结果进行对比,分析三维模型的优缺点。【结果】结果证明了该方法的可行性,建立的三维建模的土地边界清晰、建筑分明,可应用到土地调查工作中。【结论】无人机倾斜摄影技术可提高土地调查工作的完成效率,同时为我国未来的国土调查等工作提供支持。

[Purposes]In the development process of land survey in China,defects in technical means of-ten have a certain impact on the normal progress of the survey work.This paper uses unmanned aerial ve-hicle tilt photography technology to establish a realistic 3D model,through which relevant survey work is carried out,making the land survey work more efficient and convenient.[Methods]In order to explore the application advantages of drone tilt photogrammetry in land survey work,images collected by drone equipped monocular cameras were used for 3D modeling using ContextCapture Center software,and com-pared with actual survey results to analyze the advantages and disadvantages of the model.[Findings]The results have proven the feasibility of this method.The 3D modeling results in clear land boundaries and clear buildings,which can be applied to land survey work.[Conclusions]Drone tilt photography technology can increase efficiency in completing land survey work and also provide a basis for future land survey work in China.
