摘要
虚拟环境的建立是虚拟现实技术的核心内容,目前虚拟现实技术中的虚拟视景和模型生成方法大多都是基于软件设计及二维图象实现的,这是一个重大的不足之处.三维激光扫描技术的产生和发展拓展了虚拟视景和模型生成的技术实现手段,进而使虚拟现实技术有了跨越式应用.本文介绍了虚拟现实技术和三维激光技术的基本概念和原理,并且通过实验验证了三维激光扫描技术在虚拟现实中的应用.
The establishment of virtual environment is significant for the use of virtual reality technology. However, it is a great disadvantage that the creation of virtual views and models is still mainly based on software designing and 2D image. The development of 3D laser scan technology expands the means of the acquisition of virtual views and models, consequently makes VR technology hare a further application. This article introduces the concepts and principles of VR technology and 3D laser scan technology, and validate the application by experiments.
