摘　　要：依据武汉天河机场T2航站楼屋面及幕墙改造工程,研究三维激光扫描技术在既有建筑改造工程中的应用。利用全站仪与三维激光扫描仪分别进行测量,并对比测量数据误差。研究结果表明,利用三维激光扫描技术获取点云数据,可帮助工程测量人员快速获取被测目标的三维位置信息及其他信息;全站仪打点测量数据和三维激光扫描仪点云数据误差较小,验证了点云数据质量、精度均满足工程要求;三维激光扫描技术获取的点云数据为工程改造提供了可靠的信息保障,且测量时间短、数据更全面、效率更高。Based on the roof and curtain wall reconstruction project of T2 terminal of Wuhan Tianhe Airport, this paper studies the application of 3D laser scanning technology in the reconstruction project of existing buildings. The total station and three-dimensional laser scanner were used to measure and compare the measurement data errors. The research results show that the use of 3D laser scanning technology to obtain point cloud data can help engineering surveyors quickly obtain the three-dimensional position information and other information of the measured target. The error between the measured data of the total station and the point cloud data of the three-dimensional laser scanner is small, which verifies that the quality and accuracy of the point cloud data meet the engineering requirements. The point cloud data obtained by 3D laser scanning technology provides reliable information guarantee for engineering reconstruction, and the measurement time is short, the data is more comprehensive and the efficiency is higher.
