| 摘 要： | 为了用较少的参数反映人肢体皮肤的变形,该文提出以旋转圆锥曲面进行弹性连接体(人体)三维建模.模型包括人体三维骨架和代表人肢体皮肤的变形曲面方程,每个肢体只需调整2个变形参数就能反映出人肢体皮肤的变形.根据双目图像序列的轮廓估计人体变形和运动参数,包括骨架的运动参数估计和变形曲面的变形参数确定.实验结果表明:该模型能正确地反映人肢体皮肤的变形,运动估计算法能精确地估计人体运动参数. |

| Abstract: | This paper presents a new method of elastic articulated objects(human bodies) modeling based on a new revolving conic surface.The model includes a three-dimensional object skeleton and deformable surfaces equations which can represent the deformation of human body surfaces.The deformation of human body surfaces can be represented by adjusting two deformation parameters for each limb.The three-dimensional deformation and motion parameters are determined by corresponding two-dimensional image contours from a ... |
