摘要
高速公路施工现场的复杂自然条件困扰着高边坡施工监管。本文以田西高速公路西林互通段为例,采用RTK辅助无人机的免像控倾斜摄影测量技术构建施工现场的实景三维模型,提取高速公路高边坡监管信息,大大提高了施工现场高边坡监测信息提取的安全性、准确性和时效性,助力实景三维模型在高速公路施工现场监管中的应用。
The complex natural conditions at the construction worksite influence the monitoring information of high slope for expressway.Taking the Xilin interchange section of Tianxi expressway as an example,this paper built a three-dimensional(3D)real scene model of the construction site to extacte monitoring information of expressway high slope using unmanned aerial vehicle(UAV)with real-time kinematic(RTK)without ground control points(GCPs).The study results showed that UAV oblique photogrammetry could greatly improved the safety,accuracy,and efficiency of high slope monitoring information,and accelerated the application of 3D model in expressway construction worksite monitoring.
