Six degree of freedom (6DoF) video system allows users to experience t he scene from arbitrary viewpoints and perspectives,which is the development di rection of immersive video technology.According to the change of user′s viewing position in 6DOF video system,the rate allocation of multiview color and depth video is the key of high quality scene generation.A bitrate allocation scheme for area multiview video based on the quality prediction model of virtual view ( QPMVV) is proposed accordingly.Firstly,the relation between the virtual view d istortion and the coding distortion of color and depth videos is theoretically a nalyzed.Then,explorative experiments are performed to further analyze the effe ct of the coding distortion on the virtual view quality,and the QPMVV model of multiview color and depth video is established.Finally,according to the predic tion model and the constraint optimization theory,the view-level allocation we i ghts of texture and depth video are further derived.Experimental results show t hat,compared with the average allocation method,the proposed method can signif icantly improve the subjective and objective quality of virtual views.The degre e of quality improvement is related to the degree to which the virtual view posi tion deviates from the center of the reference views.The greater the deviation, the more obvious the quality improvement.
