摘要
本文以管道测量工程为研究对象,深入研究了无人机机载激光雷达在工程测量、地质测绘中的应用,与工作中的管道工程相结合,使用航空摄影测量技术与无人机机载LiDAR技术测量长输管道相结合,通过分析LiDAR飞行、地面控制测量、激光点云数据处理及DEM生成、影像数据处理及DOM生成、数字线划图(DLG)制作等,获得相应产品成果。在长输管道测量中,无人机机载LiDAR技术可代替传统测量方法,该技术应用可有效确保勘察设计质量、工期,且产品质量、精度、效果等满足要求。
In this paper,the application of airborne lidar in engineering survey and geological survey is studied.Combined with the actual work of pipeline engineering,aerial photogrammetry technology and airborne lidar technology are used to measure long-distance pipeline.Through the analysis of lidar flight,ground control survey,laser point cloud data processing and DEM generation image data processing and DOM generation,digital line drawing(DLG)production and so on,the corresp onding product results were obtained.In the long-distance pipeline measurement,the UAV airborne lidar technology can replace the traditional measurement method.The application of this technology can effectively ensure the quality and duration of survey and design,and the product quality,accuracy and effect to meet the requirements.
