3DoF VR视频图像质量主观评价方法研究

Research on the Subjective Evaluation Method of 3DoF VR Video Image Quality

3Do F VR是VR视频的一种代表性形态,也是目前虚拟现实领域普遍应用的形式。图像质量是一项会影响用户真实沉浸视觉感受的VR视频QoE的重要指标。目前国内外暂未形成VR视频领域图像质量主观评价的标准方法,为此,本文研究提出了一套3Do F VR视频图像质量主观评价方法。文章首先对VR视频主观评价的挑战、国内外进展进行分析调研,随后着重阐述了3Do F VR视频主观评价前期准备研究、主观评价量表设计、主观评价打分方法改进、实验序列制作等环节,最后进行了3DoF VR视频图像质量主观评价实验,并对实验数据进行了分析和总结。

3DoF VR is a representative form of VR video and is currently a common application form in the VR industry.Image quality is an important index of VR video QoE that can affect users'real immersive visual experience.At present,there is no standard method for subjective evaluation of image quality in VR video field at home and abroad.Therefore,this paper proposes a set of subjective evaluation methods for 3DoF VR video image quality,and focuses on the preliminary preparation,the design of subjective evaluation scale,the improvement of subjective evaluation scoring method,and the production of experiment sequence.Finally,the subjective evaluation experiment is conducted on the quality of 3DoF VR video images during the production of experimental sequences,and the experimental data is analyzed and summarized.
