无人机倾斜摄影在产业园区三维测图中的应用

倾斜摄影为地形三维测图创造条件,能够有效减少外业工作,提升作业效率。该文以产业园区为例,基于无人机倾斜摄影技术,构建园区高分辨率实景三维模型,进行大比例尺地形图三维采集作业,并开展空三精度评价和地形图精度评定,结果表明,该作业方法能够达到1∶500地形图的生产精度要求,为类似项目开展提供参考。

Oblique photography creates conditions for 3D topographic mapping,which can effectively reduce field work and improve operational efficiency.Taking the industrial park as an example,based on the UAV tilt photography technology,this paper constructs the high-resolution 3D model of the park,carries out the three-dimensional collection of large-scale topographic maps,and carries out the spatial three-precision evaluation and topographic map accuracy evaluation.the results show that this method can meet the production accuracy requirements of 1virtual 500 topographic map and provide reference for similar projects.
