英文摘要： With the spring up of 3D video related industry, it is possible to play 3D video on TV, Internet and mobile device and it appears changes with each passing day. However, the problem of visual fatigue caused by viewing 3D video becomes the bottleneck of developing 3D related industries. Thus, how to enhance the comfort of viewing 3D video becomes the hot topic of research. The project will study the theory and technologies of 3D video decoding by combining perceiving viewer and vector features inside the video coded bitstream. Starting from the point of "viewer as the foundation", the project studies the theory and technologies of 3D video decoding with visual comfort enhancement by utilizing the theory and technologies of perceiving viewer and vector feature correlation inside video coded bitstream, proposes the adaptive disparity adjustment method with consistence between convergence and accommodation by exploring the correlation model between viewer information such as viewing position and angle and the disparity within fusion area of eyes; explores the correlation between the characteristic of disparity vector distribution in the video decoding and the vertical disparity of the decoding 3D video and proposes the visual comfort enhancement algorithm; studies the correlation between the relevant feature of moti
