摘　　要：面向立体视频网络传输业务,分析影响用户感知质量的关键因素,提出了一种网络立体视频用户感知质量的多指标评价模型.该模型融合了网络服务质量因素、立体视频内容质量因素、用户互动质量因素及终端设备质量因素,利用模糊层次分析法对立体视频感知质量影响因素进行层次分析,建立评估指标体系.计算得到各指标权重,并建立最终的评价模型.通过网络仿真实验,并利用主观评测值,验证各个指标对网络传输中立体视频用户感知质量的影响.实验结果表明,此方法与用户主观评价值相关性较高,能够更全面地反映网络传输中立体视频的用户感知质量.Based on analyzing the key factors affecting the quality of experience(QoE) for the stereoscopic videonetwork business,a comprehensive multi-index evaluation model for the network stereo video QoE is proposed.Themodel combines the quality of service parameters,the stereo video quality of content,the quality of user interactionfactor and the quality of terminal server.Fuzzy analytic hierarchy process(FAHP) is used to analyze the influentialfactors of stereo video QoE hierarchically,and establish evaluation index system.Through calculating the weight ofeach index,the final evaluation model is obtained.The network simulation experiments and the subjective evaluationscores are employed in verifying the influence of each index on stereo video quality of experience,which shows thatthe proposed method achieves consistent stereoscopic video quality evaluation result with subjective assessment andcan reflect QoE of the stereoscopic video in the network.
