摘　　要：近年新兴的沉浸式视频技术,为观众提供了区别于传统视频的全新视觉听觉感受,但由于缺乏相应的技术研究,沉浸式视频在分辨率、帧率等关键技术指标方面尚未形成统一的标准。本文通过对人眼视觉特性及影响视频系统分辨率、解像力的要素进行研究,分析视场角与分辨率的关联关系,探讨沉浸式视频分辨率指标的确定方法,为技术研究、设备生产、系统构建等方面提供参考。The new immersive video technology that has emerged in recent years offers viewers a fresh visual and auditory experience that is different from traditional video.However,due to a lack of technical research,there is no coherent standard for immersive video in terms of resolution,frame rate and other key technical indicators.This article analyzes the correlation between field of view and resolution by examining the visual characteristics of the human eye and the factors that affect resolution of video systems and resolving capability.It explores the method of determining the resolution indicators for immersive video,and provides a reference for technical research,equipment production and system construction.

关 键 词：沉浸式视频 视场角 分辨率
