针对3DOF+视频搭建了一套基于视角方向的全景视频虚拟视图合成系统, 利用极少视点位置的视频信息即可准确渲染任意视点位置的视频内容, 从而为用户提供真实的观看体验。将所合成的新视点位置视图与相机采集的真实视图进行比较。实验结果表明, 所合成的虚拟视图平均客观指标PSNR为23 dB左右, 主观质量良好, 较为真实且能够提供良好的交互性与视觉体验。

In order to provide users with a true viewing experience, a panoramic video virtual view synthesis system based on view angle for 3DOF+ video was built, which could accurately render arbitrary viewpoint position by using video information with few viewpoint positions. Comparing the synthesized new viewpoint position view with the real view collected by the camera, the experimental results show that the synthesized objective view has an average objective index PSNR of about 23 dB, good subjective quality, and is realistic and can provide good interactivity and visual experience.
