| 摘 要： | 为了快速创建真实感较强的三维人脸模型，提出了基于 Kinect 的拉普拉斯网格形 变建模方法。利用 Kinect 获取彩色和深度图像信息，对深度图像进行双边滤波处理，对彩色图 像进行低层级顶点定位；构建标准三维人脸模型，并为该人脸模型中的顶点建立低、中、高 3 个级别的层级结构，通过低、中层级中顶点的位置关系创建 Sibson 局部坐标约束；利用该约束 构建彩色图像中间层级顶点，并结合深度信息对标准三维人脸模型进行拉普拉斯网格变形，获 得真实感较强的三维人脸模型。实验结果表明，该算法在建模的真实感上得到了提高，与对比 算法相比，在建模时间上得到很大的优化。

| Abstract: | In order to create a realistic 3D face model in a fast speed, a Laplacian mesh deformation modeling method based on Kinect is proposed. The Kinect is used to obtain color and depth image information, perform bilateral filtering on the depth image, perform low-level vertex positioning on the color image, construct a standard 3D face model, and establish low, middle, and high levels for the vertices in the face model. In the hierarchical structure, Sibson local coordinate constraints are created through the positional relationship of the vertices in the low and middle levels; this constraint is used to construct the middle level vertices of the color image and the Laplacian mesh deformation of the standard 3D face model is combined with the depth information to obtain a realistic 3D face model. The experimental results show that the proposed algorithm is improved in the realism of modeling, and compared with the comparative algorithms, the length of modeling time is greatly optimized. |
