基于车载点云数据的实景可量测技术研究

Research on Digital Measurable Image from Data Based on Vehicle-borne Laser Scanning

车载激光扫描系统集成激光雷达扫描技术、定位定向技术、全景获取技术于一身,可同时获取空间三维信息以及纹理信息,在数字城市信息化建设中发挥重要作用。该文通过分析车载激光扫描数据成果,将激光点云作为空间量测支撑数据,实现三维实景可量测功能,在文中详细的阐述可量测原理以及实现实景量测的关键技术,并基于Direct X开发出可量测实景应用实例,为可量测实景服务奠定基础。

Vehicle-borne laser scanning system integrated laser radar scanning technology, positioning and orienta-tion technology, panoramic image acquisition technology. This could obtain three-dimensional information and tex-ture information at the same time, which play an important role in the digital city informatization construction. In this paper, based on analyzing the results of the vehicle-borne laser scanning data, it achieved real three-dimen-sional measurement function. This paper elaborated the principles of scalability and achieved real measurement of key technologies. And we developped a scalable real application examples based on DirectX, and laid the founda-tion for scalable real service.
