多视点视频是指在场景中放置多台摄像机,记录下多个视点数据,提供给用户视点选择和场景漫游的交互式媒体应用.多个摄像机从不同视角同时拍摄同一场景得到的一组视频信号,每一个摄像机代表一个不同的视角.可同时传输多个空间角度的视频流到用户端,并合成用户所需要的视域图像.多视点视频是一种新型的具有立体感和交互操作功能的视频,是未来一种极具应用前景的多媒体应用.然而,当前多视点的无线网络带宽分配机制中,都没有考虑大量的、不同解码能力的用户共存时的效率问题.一般情况下,合成视域往往需要至少左右两边(两条以上)的参考视频同时传输到用户端,才能使合成的视域质量不低于直接传输的视点...

Multi-view video refers to placing multiple cameras in the scene,recording multiple view data,and providing the user with the interactive ability of view selection and scene roaming. A set of video signals obtained by multiple cameras simultaneously shooting the same scene from different perspectives,each camera represents a different perspective.Video from multiple spatial angles can be simultaneously transmitted to the client,and the image of view area required by the user can be synthesized.Multi-view video is a new type of video with three-dimensional sense and interactive operation functi...
