摘　　要：为了提高城市部件采集效率及精度,本文结合移动车载激光扫描技术在城市道路空间三维数据采集中的优势,提出将移动车载激光扫描技术应用到城市部件提取中。首先,通过外业采集试验区点云数据及基准站坐标数据,解算得到原始点云数据;其次,通过对原始数据进行去噪、抽稀等预处理后,得到满足城市部件提取要求的高精度点云数据;最后,使用自动提取平台提取得到试验区城市部件数据。通过将GNSS-RTK测量数据与本文提取部件数据进行对比,结果表明,基于移动车载激光扫描技术的城市部件采集技术能够满足城市部件采集的精度要求,可大大提高城市部件采集效率。本文的研究可为智慧城市建设中城市部件管理提供了有益借鉴。In order to improve the efficiency and accuracy of urban component collection,this paper proposes to apply mobile vehicleborne laser scanning technology to urban component extraction,combining the advantages of mobile vehicle-borne laser scanning technology in urban road space three-dimensional data collection.Firstly,the original point cloud data is obtained through the field collection of the point cloud data in the test area and the coordinate data of the reference stations;secondly,after preprocessing the original data,such as denoising and thinning,the high-accuracy point cloud data meeting the requirements of urban component extraction is obtained;finally,using the automatic extraction platform to extract the urban component data in the test area.By comparing the GNSS-RTK measurement data with the component data extracted in this paper,the results show that the urban component acquisition technology based on mobile vehicle-borne laser scanning technology can meet the accuracy requirements of urban component acquisition,and can greatly improve the efficiency of urban component acquisition.The research in this paper can provide a useful reference for urban component management in smart city construction.
