  • Publication number: 20250218038
    Abstract: An image generating system having high face positioning precision includes an image converting module and an image generating module. The image converting module analyzes the face of an image via an artificial intelligence model to generate a plurality of feature points, each with a feature point coordinate. The image generating module saves a lookup table and a default grid model having a plurality of grid points. The number of the feature points is equal to that of the grid points. The lookup table records the grid point coordinate of the grid point corresponding to the feature point coordinate of each feature point. The image generating module finds out the feature points matching the grid points, and aligns at least a portion of the grid points with the feature points corresponding thereto so as to combine the default grid model with the face and generate a real-time 3D face model.
