摘要
当前车载激光扫描技术日趋稳定,车载点云扫描已经逐渐被大众认可,开始广泛应用于国民经济建设的众多领域。点云数据具有数据精度高、数据量大、采集难度大等特点,常采用单机版客户端软件完成各种计算与采集,在浏览器中的点云查看与应用。随着WebGL与流式传输与渲染技术的发展,海量点云数据也开始走向网络互联。本文基于Potree、车载点云数据自动提取、网络发布等技术,实现了车载点云数据的在线快速浏览。
At present,the vehicle-borne laser scanning technology is becoming more and more stable.Vehicle-borne point cloud scanning has gradually been recognized by the public and has begun to be widely used in many fields of national economic construction.Point cloud data has the characteristics of high accuracy,large amount of data and difficult collection.Single-machine version of client software is often used to complete various calculations and acquisition.Very few point clouds in browsers can be viewed and applied.With the development of WebGL and streaming transmission and rendering technology,massive point cloud data has begun to move towards network interconnection.Based on Potree,automatic extraction of vehicle points cloud data,network publishing and other technologies,this paper achieves fast online browsing of vehicle point cloud data.
