摘　　要：现有的基于运动捕获的动画普遍存在投资大 ,人体的运动受到捕获设备限制等缺陷 提出了新的基于视频的人体动画技术 ,首先从视频中捕获人体运动 ,然后将编辑处理后的运动重定向到动画角色 ,产生满足动画师要求的动画片段 对其中的运动捕获、运动编辑和运动重定向等关键技术进行了深入研究 ,并基于这些关键技术开发了一个基于双像机的视频动画系统 (VBHA) ,系统运行结果表明了从来源广、成本低的视频中捕获运动 。To overcome the shortcomings of costly equipment and human body motion limited by motion capture equipment inherent in traditional motion capture based animation, a new idea of producing computer animation is presented in this paper Firstly, motion of human body is captured from video Then the edited motion is retargeted from human to animation characters and cartoons are produced, that meet the requirement presented by animator The key technologies in video based animation, such as motion capture, motion editing and motion retargeting, are studied Based on the study, a video based human animation (VBHA) system based on two cameras is implemented Experimental results show the possibility of capturing precise motion from abundant and cheap video and producing vivid animation through retargeting motion from human to other characters
