摘　　要：随着我国城市化进程的不断加快,市政改扩建工程对交通流的影响也日益突出。本文通过借助无人机搭载可见光相机,拍摄高精度正射影像图并用于交通导改工作,详述了高精度正射影像图的制作流程与精度控制方法,分析了其在市政工程交通导改工作的使用方法和功能效果,并通过工程实例进行应用。结果表明,高精度正射影像图在场地环境调查、辅助交通组织方案设计及导改效果实时监控调整方面均具有良好的效果,同时还可以与设计图纸、BIM模型叠合进行导改施工技术交底,减少车辆平均行程时间15%,减少围挡安装返工率20%,节约项目成本150余万元。With the continuous acceleration of China's urbanization process,the impact of municipal reconstruction and expansion projects on traffic flow is becoming increasingly prominent.In this paper,a high-precision orthophoto map is taken with the help of a UAV equipped with a visible light camera and used for traffic guidance and reform.The production process and accuracy control method of high-precision orthophoto map are described in detail,along with its usage and functional effect of traffic diversion and modification in municipal engineering are analyzed,and the application is carried out through engineering examples.The results show that the high-precision orthophoto map has a good application effect in site environmental investigation,auxiliary traffic organization scheme design and real-time monitoring and adjustment of the guidance and reform effect.At the same time,they can be overlaid with design drawings and BIM models for guidance and renovation construction technology disclosure,reducing the average travel time of vehicles by 15%,reducing the rework rate of fence installation by 20%,and saving project costs of more than 1.5 million yuan.
