基于云存储的3D直播系统设计与实现

Design and Implementation of 3D Live Broadcast System Based on Cloud Storage

随着互联网技术的快速发展,观看网络直播成为人们主要的线上娱乐方式之一。目前市面上存在很多直播平台,在这些平台日趋广泛的同时,也产生了很多改进的空间,如何增强用户的临场感体验是其中至关重要的一个方面。一般在实际观看中,用户所看到的是2D画面,观看体验感不强,且主播画面与用户实时显示画面,时延大概在2s以上,互动感较差。采用3D直播的方式,将主播以三维虚拟人物形象的方式呈现,将增强用户的体验感。而现有的3D直播平台存在一定的局限性,用户依然是被动的观看直播画面,因此对现有直播平台架构进行了研究和改进。基于Unity软件,采用C/S架构,将人物渲染的流程从局域网拓展到广域网中,在客户端将被动观看变为主动观看,再通过引入CDN和5G网络技术降低传输时延,完成3D直播系统平台设计与搭建。通过该平台可拉近用户与主播的心理距离,增加用户观看网络直播的趣味性与临场感体验。

At present,there are many live broadcast platforms on the market.As these platforms become more widespread,they also have a lot of room for improvement.How to enhance the user's presence experience is a crucial aspect.Generally in actual viewing,the user sees a 2D picture,the viewing experience is not strong,and the anchor picture and the user display the picture in real time,the delay is about 2s or more,and the interaction is poor.Using 3D live broadcast,presenting the anchor as a three-dimensional virtual character image will enhance the user experience.However,the existing 3D live broadcast platform has certain limitations,and users are still passively watching live broadcast pictures.Therefore,this system researches and improves the existing live broadcast platform architecture.Based on Unity software,the C/S architecture is used to extend the process of character rendering from the local area network to the wide area network.At the client,passive viewing is changed to active viewing.Then,the introduction of CDN and 5G network technology reduces the transmission delay and completes the 3D live broadcast system.Platform design and construction.Through this platform,the psychological distance between the user and the anchor can be shortened,and the fun and presence experience of the user watching the webcast is increased.
