论文摘要
在本文中，我们将重点放在身临其境环境中的主观和客观点云质量评估（PCQA）上，并研究压缩失真中的几何和纹理属性的效果。使用具有六个自由度的头部安装显示（HMD），我们建立了一个主观PCQA数据库，名为SIAT Point Cloine Cloud质量数据库（SIAT-PCQD）。我们的数据库由MPEG点云编码器压缩的340个变形点云与20个序列和17对几何和纹理量化参数组合。本文进一步讨论了扭曲的几何形状和纹理属性的影响。然后，我们提出了两种基于投影的客观质量评估方法，即基于加权视图投影模型和基于贴片投影的模型。我们的主观数据库和发现可用于点云处理，传输和编码，尤其是用于虚拟现实应用程序。主观数据集已在公共存储库中发布。
In this paper, we focus on subjective and objective Point Cloud Quality Assessment (PCQA) in an immersive environment and study the effect of geometry and texture attributes in compression distortion. Using a Head-Mounted Display (HMD) with six degrees of freedom, we establish a subjective PCQA database, named SIAT Point Cloud Quality Database (SIAT-PCQD). Our database consists of 340 distorted point clouds compressed by the MPEG point cloud encoder with the combination of 20 sequences and 17 pairs of geometry and texture quantization parameters. The impact of distorted geometry and texture attributes is further discussed in this paper. Then, we propose two projection-based objective quality evaluation methods, i.e., a weighted view projection based model and a patch projection based model. Our subjective database and findings can be used in point cloud processing, transmission, and coding, especially for virtual reality applications. The subjective dataset has been released in the public repository.
