Embodiment Construction

[0176] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0177] For ease of understanding, before explaining the embodiments of the present invention in detail, terms involved in the embodiments of the present invention will be explained first.

[0178] realistic experience

[0179] Realistic experience is mainly used to indicate the restoration degree of the virtual environment of VR multimedia to the real environment. Among them, the higher the degree of restoration, the stronger the user's immersive feeling. Therefore, the realistic experience can also reflect the user's immersive feeling.

[0180] pleasure experience

[0181] Pleasure experience is mainly used to indicate the impact of network transmission quality on the playback quality of VR multimedia during the playback of VR...

Abstract

The invention discloses a determination method and device for the experience quality of VR multimedia, and belongs to the technical field of VR. The method comprises the following steps: in a playingprocess of the VR multimedia, a first sense parameter, a second sense parameter and a third sense parameter of the VR multimedia are acquired, wherein the first sense parameter, the second sense parameter and the third sense parameter are obtained through sampling according to at least two same perception dimensions and are parameters influencing reality sense experience, pleasure sense experienceand interaction sense experience respectively; and the mean opinion score (MOS) of the VR multimedia is determined on the basis of the first sense parameter, the second sense parameter and the thirdsense parameter of the VR multimedia. According to the method, due to the fact that the third sense parameter is the parameter influencing the interaction sense experience, the interaction characteristic of the VR multimedia is considered when the MOS of the VR multimedia is determined through the third sense parameter, and the determined experience quality of the VR multimedia is more accurate.

Description

technical field [0001] The present application relates to the field of virtual reality (Virtual Reality, VR) technology, and in particular to a method and device for determining the quality of experience of VR multimedia. Background technique [0002] VR multimedia refers to the use of multiple cameras and sound acquisition equipment to capture and reproduce the real environment panorama, or to generate a virtual environment comparable to the real environment through computer animation (Computer Animation, CG), virtual engine and other technologies, so as to realize Multimedia with three-dimensional space display function. When users watch VR multimedia, they can place the terminal used to play VR multimedia in the VR device, and watch video images from any angle from up, down, left, and right through the worn VR device, and listen to the audio played synchronously with the VR multimedia. In the process of appreciating the VR multimedia, the user can be completely placed in...
