| 摘 要： | 在虚拟环境中，对人体头部变形曲面提取特征并参数化，建立基于弹簧质点系统的标准几何模型；借助重叠图像拼接技术形成纹理图像；根据纹理图像调整几何模型特征参数，配准图形和图像形成特定的变形几何模型，再把拼接图像纹理映射到变形几何模型上，得到一种真实感人体头部模型。 |
| 关 键 词： | 图像拼接 特征参数化 弹簧质点系统 纹理映射 真实感模型 |

| Abstract: | In a visual environment, the characters of transformative head surface were parametrically drown out and a standard geometrical model of head was established based on the spring mass system. The texture image by using the mosaic technology was built. The parameters of the standard model were adjusted based on the texture image. The real feeling human head model was made by matching the graphics and image and by texture mapping. This modeling method taking full advantage of the existing CAD technologies and photographed texture picture can build photo realistic 3D model. This method meets the vision demand of the real time graphics rendering and has good practicability in the visual environment. |
| Keywords: | image mosaic characteristic parameter spring mass system texture mapping reality model |
