云计算和自由视点视频相结合的实时监控系统

摘要

The paper proposes a three-dimensional real-time display mobile video surveillance program based on cloud computing and the free viewpoint video technologies to effectively solve limitations of computing resources and storage capacity.Our scheme uses the random accessibility of cloud computing to obtain video information,and process the collected video using the distributed processing and transmission.Then,it renders 3D video by attaining free view point imaging.With our proposed architecture,users can choose the viewing angle freely to watch 3D videos on mobile devices by portable mobile devices.This architecture realizes the integration of the cloud computing technology,free technical viewpoint and 2D to 3D video.The three-dimensional image based on cloud computing and transmission system is a new system to monitor accident sites for greater visual effect.%为有效解决系统计算资源以及存储能力的局限问题,提出一种基于云计算和自由视点技术相结合并且用于3D实时显示的移动视频监控方案.该方案通过使用随机接入云计算技术获取视频信息,并对采集到的视频进行分布式处理与传输,然后获取自由视点的成像,进而绘制3D视频.提出的方案可以使用户通过便携式移动设备自主选择观看角度,获取3D视频.该体系结构实现了云计算技术、自由视点技术以及2D转3D视频等多种技术的整合.基于云计算的三维图像和传输系统是一种提高视觉效果并且可用于事故现场的全新系统.
