| 文章从点点对应，线线对应入手，首先给出了根据已知二维影像特征求得与其对应的三维模型特征参数的方法，然后给出了已知人体二维影像特征求解三维人体模型特征参数方法的详细描述.基于这一思想，实现了一个动画系统Video & Animation Studio.文章最后给出了一个由该系统实现的人体行走的例子. |

| Abstract: |
| In this paper, starting from point-point and line-line correspondence, a detailed description of the calculation of projection parameters for 2D video features and 3D model features correspondence is presented firstly. Then a detailed description of the calculation of projection parameters for 2D human video features and 3D human model features correspondence is given. At the same time, an animation example of human walking is introduced which is produced by an animation system called Video&Animation Studio. The system is designed according to the above idea. |
| Key words: Human animation, correspondence between video features and model features. |
