摘要

近年来，科技界掀起一场"虚拟现实"风暴，给人们带来了前所未有的视听体验。全景视频作为虚拟现实的主要构造方式之一，凭借其良好的用户体验与人机交互性被广泛应用于医疗、娱乐、教育以及工业设计等诸多领域，在一定程度上改变了原有的生产设计方式。与此同时，用户对于全景视频视觉体验的要求也日益增长，如何为用户提供良好的全景视频视觉体验已成为近年来相关领域的研究热点。本文以HTC Vive平台为基础，结合虚拟现实技术相关指标以及用户对于全景视频视觉体验的要求，搭建了全景视频显示系统，并在此平台上通过主观实验分析了渲染全景视频时的球体网格面片数与全景视频主观质量之间的关系。实验结果表明，对于分辨率为720 P、1 080 P以及4K的视频，当面片数小于64时，视频的主观质量与面片数量成正相关关系；当面片数超过64后，视频主观质量方可由其自身参数所决定。本文中所搭建的全景视频显示系统以及文中相关结论可为后续有关全景视频的研究与应用开发提供有效的建议。

Abstract

In recent years

"virtual reality" has been more and more popular and brought with it an unprecedented fantastic user experience. Panorama video

as one of the main construction ways of virtual reality

on account of its good user experience and human-computer interaction ability

has been widely used in many fields

such as medical

entertainment

education and industrial design. With the increasing demands for good user experience

how to ensure the user experience of panorama video in various applications now becomes the next hot topic. In this paper

we proposed a panoramic video display system based on the HTC Vive platform. The relationship between the number of patches of the sphere used for rendering and the subjective quality of the panoramic video is analyzed by subjective experiment. The result indicates that for 720 P

1 080 P and 4K videos

when the number of patches is smaller than 64

the subjective video quality has a positive correlation with it. When the number of patches exceeds 64

the subjective quality will be determined by the video parameters. The proposed panoramic video display system and the relevant conclusions can provide effective suggestions for the subsequent research and application development of panoramic video.
