摘要/Abstract

摘要： 针对手机无法渲染可交互的高质量三维场景这一弊端,提出一种面向手机的云端VR应用框架。此框架结合云渲染和VR技术在手机端实现可交互高质量三维场景的立体显示,并以手机浏览器作为客户端,利用视频块流传输图像数据、消抖算法(AJA)处理交互数据,实现Web端轻量级渲染,不仅降低了移动端数据可视化运算成本,还避免使用插件和下载安装包。实验表明本文框架的显示帧率能达到30帧每秒,带宽控制在80 kb/s以内,能稳定地在手机上实现传统App无法实现的逼真VR体验。

Abstract: A VR application framework based on cloud computing is proposed to overcome the difficulty of interactively generating high quality 3D scene images on mobile phones. We combine the cloud-based rendering and the VR technology. Our framework uses a mobile browser as a client, transmits the image data by the video block stream, processes the interactive data by the anti-jitter algorithm, and has accomplished the web-based lightweight rendering. The framework reduces the cost of data visualization on mobile phone and avoids the need of installing a plug-in package. The experimental results show that our display rate could be improved to 30 frames per second(fps), and the bandwidth could be limited under 80 kb/s. With the proposed framework, we can obtain much better VR Experience than the general mobile applications.

Key words: cloud-based rendering, VR technology, web-based lightweight rendering, video block stream, anti-jitter algorithm, mobile plug-in
