道路扩容勘察设计中激光航空摄影测量技术的应用

The Application of Laser Aerial Photogrammetry Technology in Road Expansion Survey and Design

文章以G5京昆高速川陕界至广元扩容工程项目为例,分析了项目和地理概况,重点分析了航飞数据采集流程及像控点布设、像片调绘与补测等内容,提出了摄影质量控制措施及重点,包括飞行质量控制、摄影质量控制。通过分析得出,在道路测量工作中,航空摄影测量技术的应用能在短时间内获取大量数据信息,提高测量精度和效率,还可以节省人力、物力和时间成本。

Taking the expansion engineering project of Sichuan-Shaanxi border to Guangyuan section on G5 Beijing-Kunming Expressway as an example,this paper analyzes the general situation of the project and geography,focuses on the analysis of the flight data acquisition process and the image control point layout,photo annotation and supplementary measurement,and puts forward the control measures and key points of photography quality,including flight quality control and photography quality control.Through analysis,it is concluded that the application of aerial photogrammetry technology in the road measurement work can obtain a large amount of data information in a short time,improve the measurement accuracy and efficiency,and save manpower,material resources and time costs.
