基于无插件化的三维室内点云可视化系统

Based on Non-plug-in Three-dimensional Indoor Point Cloud Visualization System

科技的不断进步推动着测绘技术的不断发展,传统的测量技术已经不能满足大众对于建筑的直观感受。三维激光扫描技术以其获取数据速度快、精准度高、数据信息量大、实用性强等特点逐渐成为测绘领域中的重要测绘技术[1]。本文详细介绍了三维室内点云漫游系统的开发框架和核心技术。分析三维点云数据在采集过程中所遇到的问题和处理方法。同时引用potree.js将武汉大学实验室部分的室内三维点云为例,结合THREE.JS、MapBox、HTML5等技术进行室内点云漫游的构建,实现了室内点云无插件化漫游、测量等交互。

The continuous advancement of science and technology has promoted the continuous development of surveying and mapping technology.The traditional measurement technology can no longer satisfy the public's intuitive feeling of architecture.The 3D laser scanning technology has become an important mapping technology in the field of surveying and mapping because of its fast data acquisition,high precision,large amount of data information and strong practicability [1].This paper introduces in detail the development framework and core technology of 3D indoor point cloud roaming system.Analyze the problems and processing methods encountered in the acquisition process of 3D point cloud data.At the same time,we refer to potree.js as an example of the indoor 3D point cloud in the laboratory part of Wuhan University.Combining THREE.JS,MapBox,HTML5 and other technologies to construct indoor point cloud roaming,realizing the interaction of indoor point cloud without plug-in roaming and measurement.
