In order to improve the efficiency and accuracy of urban component collection,this paper proposes to apply mobile vehicle-borne laser scanning technology to urban component extraction,combining the advantages of mobile vehicle-borne laser scanning tech-nology in urban road space three-dimensional data collection. Firstly,the original point cloud data is obtained through the field collec-tion 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 tech-nology 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 ur-ban component management in smart city construction.
