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.
