基于车载点云数据的实景可量测技术研究

摘要

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DirectX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 orientation technology, panoramic image acquisition technology.This could obtain three-dimensional information and texture 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-dimensional 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 foundation for scalable real service.
