Overall user experience quality assessment method of VR audio and video

Abstract

The invention discloses an overall user experience quality assessment method of VR audio and video, particularly relates to an audio and video overall user experience quality assessment method in a virtual reality environment, and belongs to the field of multimedia technology. The implementation method of the invention is as follows: with respect to to-be-measured VR audio and video and referenceVR audio and video, respectively calculating a video quality parameter, an audio quality parameter, an audio and video time parameter and an audio and video space parameter of the to-be-measured VR audio and video through video quality, audio quality and audio and video time interaction and audio and video space interaction models in a first layer; and inputting the four parameters into an overall quality fusion model in a second layer, and finally outputting an overall quality score of the to-be-measured VR audio and video, wherein the space interaction model is implemented by a function relationship designed based on subjective feeling of users. By adoption of the overall user experience quality assessment method disclosed by the invention the influence of the audio and video space interaction on the overall user experience quality of the VR audio and video can be reflected, and the assessment effect better conforms to the subjective feeling of the users.

Description

technical field [0001] The invention relates to a method for evaluating overall user experience quality of audio and video, in particular to evaluating overall user experience quality of audio and video in a virtual reality environment, and belongs to the field of multimedia technology. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) technology has brought people a new audio and video experience, in which panoramic video and spatial audio are an integral part of the immersive experience. With its good user experience and human-computer interaction, virtual reality technology is widely used in many fields such as entertainment, education, medical treatment and industry, and has changed the original production design method to a certain extent. In the virtual reality environment, it is not only the panoramic video that affects the user experience, but also the spatial audio and the mixed effect of audio and video, which means that the user ex...
