摘要
地面激光雷达作为一种革命性测量新技术,为铁路勘测提供了一种崭新的手段。针对传统铁路勘测劳动强度大、工作效率低、安全风险高等问题,对基于地面激光雷达技术的铁路勘测方法进行研究,提出了适用于铁路勘测的地面激光数据采集、处理和应用方案,并从非接触式测量、数据多用性以及项目补测三个方面分析了地面激光雷达的应用优势。实际工程应用表明,基于地面激光雷达技术可以快速、高精度地生产铁路勘察设计所需的断面和大比例尺工点地形图。相比于传统测量方法,勘测效率提高3倍以上,且具有更高的精度和可靠性,推广应用前景广阔。
As a revolutionary new measurement technology,ground LIDAR provides a new means for railway surveying.Aiming at the problems of high labor intensity,low work efficiency and high safety risk in traditional railway survey,this paper studies the railway survey method based on ground LIDAR technology,and puts forward the ground LIDAR data acquisition,processing and application scheme suitable for railway survey.In addition,the application advantages of ground LIDAR in railway survey are analyzed from three aspects:non-contact measurement,data versatility and project supplementary survey.The practical engineering application shows that:based on the technology of ground LIDAR,the section and large scale topographic map of construction site required by railway survey and design can be produced quickly and accurately.Compared with the traditional measurement method,the survey efficiency is increased more than 3 times,and has higher accuracy and reliability,so it has a wide application prospect.
