| 摘 要： | 由于人体肌肉在变形过程中具有保体积的约束特性，且肌肉运动缺乏三维多角度呈现，为此，提出了一种人体肌肉的参数化建模及变形方法。基于MRI (magnetic resonance imaging)数据，利用其生成的切片图像提取外轮廓线进行构建三维肌肉模型；层次化定义肌肉特征，建立语义参数间的映射关系，实现肌肉的保体积变形；通过建立向量值动态四阶微分方程使特征曲线动态模拟肌肉的变形过程，并建立骨骼运动与肌肉变形之间的对应关系。以人体肱二头肌为例进行实验，验证了此方法的有效性。

| Abstract: | Due to the volume preserving constraint of human muscle in the deformation process, and the lack of three-dimensional multi-angle representation of muscle motion, a parametric modeling and deformation method of human muscle is proposed. Based on MRI (magnetic resonance imaging) data, the external contour line is extracted from the slice image generated by MRI data to construct a three-dimensional muscle model; muscle features are defined hierarchically, and the mapping relationship between semantic parameters is established to realize the volume preserving deformation of muscle; by establishing a vector-valued dynamic fourth-order differential equation, the feature curve dynamically simulates the process of muscle deformation, and establishes the corresponding relationship between skeletal motion and muscle deformation. The effectiveness of this method is verified by experiments with biceps brachii as an example. |
