摘要
机载激光扫描(Light Detection and Ranging)技术作为新兴的现代化测量技术,目前广泛用于测绘的各个领域中,对其数据标准格式(LAS格式)的研究具有重要意义。VTK(Visualization Toolkit)是一种用于图像处理和可视化的工具包,本文通过VTK数据流的特点,在挪威TrollTech公司开发的Qt平台上以C++为开发工具,设计和实现了机载LiDAR点云数据的三维可视化,为后期对数据和影像的进一步研究打下了基础。
As a new modern measurement technique, Light Detection and Ranging is now widely used in the fields of surveying and mapping, so it is very important to research the standard format（ LAS format）of LiDAR data. VTK is a tool used in image processing and visualization. According to the characteristics of the VTK data,the article designed and re- alized 3D visualization of LiDAR point cloud data. It was realized through C＋＋ technology in the platform of Qt which is developed by Norway TrollTech Company. The results lay the foundation for further research of data and images.
