摘要
为了解决传统测绘技术手段在高海拔地区铁路建设中工作效率低、测量精度差、安全隐患高等问题.采用垂起固定翼无人机飞行平台搭载倾斜摄影相机,针对高海拔地区地貌特征和勘测要求,建立完整的航飞技术工作流程,利用无人机倾斜摄影测量技术完成铁路现场勘测工作,可有效减少高海拔地区铁路勘测的外业工作量,由检查点数据对比分析结果可以看出,检查点平面中误差为 0.06 m,高程中误差为0.12 m,满足地形图和实景三维模型的精度要求.研究结果表明,无人机倾斜摄影测量技术可为生产项目提供靠高清影像、地形图数据和三维模型,无人机具有机动性、灵活性、不受地形和地物的限制等优势,可以提高生产效率,降低作业成本,大幅降低高海拔地区测量作业的安全隐患.
Abstract
In order to solve the problems of low work efficiency,poor measurement accuracy,and high safety hazards of traditional surveying and mapping techniques in railway construction in high-altitude areas,by using a vertical fixed-wing UAV flight platform equipped with an oblique photography camera,a complete aerial photogrammetry technology workflow was established based on the terrain characteristics and survey requirements of high-altitude areas.The use of UAV oblique photogrammetry technology to complete railway field survey work could effectively reduce the field workload of railway survey in high-altitude areas.From the comparison and analysis of checkpoint data,it can be seen that the MSE in the plane of the checkpoint is 0.06 m,and the MSE in the elevation is 0.12 m,which meets the accuracy requirements of topographic maps and real scene 3D models.The research results indicate that UAV oblique photogrammetry technology can provide production projects with high-definition images,terrain map data,and 3D models.UAV have advantages such as mobility,flexibility,and are not limited by terrain and features,which can improve production efficiency,reduce operating costs,and significantly reduce safety hazards in high-altitude areas.
