摘要
随着以无人机为主的各种倾斜摄影系统的涌现,无人机倾斜摄影建模已经常态化。基于三维实景建模可以更加直观、高效、方便地开展人员管控。本文以河北省唐山市某铁路为例,介绍了无人机倾斜摄影测量在大范围带状区域三维重建的关键技术,通过外业采集的检查点对模型进行精度检验,结果表明,利用该技术获得的三维模型具有真实、精度高、效率快、效果好等优势,为大范围带状区域三维重建提供了一种高效的新方法。
With the emergence of various oblique photography systems dominated by UAVs,UAV oblique photography modeling has become normalized.Based on realistic 3D modeling,personnel control can be carried out more intuitively,efficiently,and conveniently.This paper,taking a railway in Tangshan city,Hebei province as an example,introduces the key technology of UAV oblique photogrammetry for 3D reconstruction of large-scale strip areas.Through field collected checkpoints to verify the accuracy,the results show that the 3D model obtained by this technology has the advantages of reality,high accuracy,high efficiency,and good effect,which provides a highly efficient new method for 3D reconstruction of large-scale strip areas.
