摘要
基于全景图像的虚拟现实(VR)漫游技术,具有图像质量均匀、细节真实程度更高等特点,应用范围较广。在虚拟现实全景漫游中,实物虚化和虚物实化是两个基本步骤。实物虚化就是通过全景图的拍摄、拼接,将现实世界的多维信息同步映射到数字空间,生成虚拟场景;虚物实化则是基于计算机和仿真技术,构建三维模型,让用户感知虚拟现实场景,增强其沉浸感。本文在概述虚拟现实场景制作和全景漫游模型构建技术的基础上,分别从降低内存消耗、减少内存漏洞等方面,提出了虚拟现实全景漫游技术的优化策略,为该技术的成熟运用提供了一定帮助。
The virtual reality(VR)roaming technology based on panoramic images has the characteristics of uniform image quality and higher real degree of details,and has a wide range of applications.In the virtual reality panorama roaming,virtual reality and virtual reality are two basic steps.The virtual reality is to synchronously map the multi-dimensional information of the real world to the digital space through the shooting and splicing of the panorama to generate a virtual scene;,enhancing its immersion.Based on the overview of virtual reality scene production and panoramic roaming model construction technology,this paper proposes an optimization strategy for virtual reality panoramic roaming technology from the aspects of reducing memory consumption and reducing memory loopholes,which provide some help for the mature application of this technology.
