摘　　要：针对传统视频跳帧缺帧补偿方法存在效率低且补偿不完整问题,提出一种基于帧间投影算法的三维视频跳帧缺帧动态补偿方法。使用帧间投影算法使帧间运行转化为两个单独波形,得出参考帧在水平方向与垂直方向运动矢量,并利用逆变转化限制旋转、平移等基础变形,减少后续补偿的干扰向量,分析三维视频补偿需求构建相应深度卷积神经网络,利用训练模块对两种波形进行训练,通过不同方法测定三维视频补偿效率,获取三维视频跳帧缺帧动态补偿完整性。实验结果得出,所提方法在三维视频跳帧、缺帧补偿上效率更高,并且较比传统方法更快。据此可得出结论为所提三维视频跳帧缺帧补偿方法的性能更好。Due to low efficiency and incomplete compensation of traditional method,this article focuses on a dynamic compensation method of frame skip and frame missing in 3 D video based on inter-frame projection algorithm.The inter-frame projection algorithm was used to change the inter-frame operation into two separate waveforms,so as to get the motion vector of reference frame in horizontal direction and vertical direction.Then,the inverter transformation was used to limit the rotation,translation and other basic deformation,so as to reduce the interference vector of subsequent compensation.In addition,the demands of 3 D video compensation were analyzed to build the corresponding convolution neural network.Meanwhile,the training module was used to train the two waveforms.Through different methods,3 D video compensation efficiency was determined.Thus,the completeness of dynamic compensation of frame skip and frame missing in 3 D video was obtained.Simulation results show that the proposed method has higher efficiency in frame skipping and frame missing compensation of 3 D video,and it is faster than the traditional method.Therefore,the proposed method has better performance.
