无人机倾斜摄影在市政道路设计中的应用

The application of UAV photography in municipal road design

为了验证无人机倾斜摄影技术能否应用于市政道路改造设计项目的地形图生产,设计了利用无人机倾斜摄影技术生产市政改造项目地形图的技术流程,以辽源红五星互通改造设计项目为依托,开展了无人机倾斜摄影数据的获取与建模工作,并检验了倾斜摄影模型成果的精度,生产了地形图。项目实践应用结果表明,利用无人机倾斜摄影技术生产的三维倾斜模型平面中误差8.2 cm,高程中误差11.2 cm,生产的地形图能够满足市政道路改造项目的应用,倾斜模型能在很大程度上节省市政道路改造设计的外业勘测时间。

In order to verify whether unmanned aerial vehicle(UAV)oblique photography technology can be applied to the production of topographic map used by municipal road reconstruction design project,the technical process of producing topographic map for municipal reconstruction project was designed,using oblique photography technology of UAV.Based on the reconstruction design project of Liaoyuan Hongwuxing overpass,the work of obtaining oblique photographic data and establishing oblique photography model were carried out by UAV,the accuracy of oblique photography model was tested,and topographic map was produced.The results showed that the plane median error and elevation median error of 3D oblique model produced by oblique photography technology of UAV were 8.2 cm and 11.2 cm respectively,the topographic map could meet the application of municipal road reconstruction project,and the oblique model had greatly saved the survey time of municipal road reconstruction design.
