中文摘要：

提出并实现了一种在现有网络带宽条件下即可实现的交互式立体视频流传输系统．该系统首先采用人脸检测与跟踪技术确定用户的位置信息，并将该信息实时反馈到服务器端，服务器端根据客户的位置信息自适应选择与用户观看角度最匹配的两路立体视频流数据发送至客户端．在现有的网络带宽条件下，该系统可为用户提供高质量的立体视频，还能为用户提供自主选择观看视角的能力，保证用户总能以最佳的角度观看立体视频．

英文摘要：

This paper presents the system architecture of user-driven interactive 3D video streaming transmission, which is simple to be realized with legacy displays. First, a novel idea is proposed, in which the viewer＇s position is determined using face detection and tracking technology. Second, the location information is employed as feedback to the video server-side in real time. Finally, the server adaptively selects the best matched parts of video stream data with the user＇s viewing angle. Under the existing network bandwidth conditions, the proposed system enables the viewers to select their viewing directions at their willing and enjoy a high quality of 3D experience anywhere they like.
