车载LiDAR在城市部件采集中的应用

Application of Vehicle-borne LiDAR in Urban Component Acquisition

近几年,我国城市建设面积不断扩大,城市基础管理的难度也随之增加,数字城管项目作为城市管理信息化发展过程中的一项重要措施,对城市管理工作水平的提升发挥了重大作用。车载LiDAR移动测量技术作为一种高新技术,在我国也取得了较快的发展,这种技术能够对城市部件数据采集提供很多帮助。本文详细研究了车载LiDAR在城市部件采集中的应用,通过对比传统CORS测量数据,分析了其技术流程,并对其点云数据精度进行了评估,为数字城管中的城市部件采集工作提供了一个新方法。

In recent years, with the accelerating process of urbanization construction, the difficulty of urban basic management also increases.As an important measure in the process of urban informatization development, digital city management project plays a significant role in improving the level of urban management. Vehicle-borne LiDAR measurement technology is relatively mature in China ,and it can improve the capabilities of city component data acquisition.This paper studied the application of vehicle-borne LiDAR in urban component acquisition.By comparing with the traditional CORS measurement data, the technical process and the accuracy of point cloud data were analyzed in detail, which provided a new method for the acquisition of urban components in digital urban management.
