Expression migration method and electronic equipment
The invention discloses an expression migration method and electronic equipment, andthe method comprises the steps: obtaining two-dimensional coordinates of a keyfeature point of a human face in a video frame; obtaining the two-dimensionalcoordinates of a key feature point, corresponding to the key feature point of the humanface, in a preset 3D model; obtaining the new two-dimensional coordinates of all toppoints of the preset 3D model according to the relation between the two-dimensionalcoordinates of the key feature point of the human face and the two-dimensionalcoordinates of the key feature point in the preset 3D model; obtaining the comparisonrelation between the two-dimensional coordinates of the key feature point of the humanface and the two-dimensional coordinates of the key feature point in the preset 3Dmodel obtaining the new Z-axis coordinates of all top points of the preset 3D modelaccording to the comparison relation; and displaying a corresponding 3D imageaccording to the new two-dimensional coordinates of all top points of the preset 3Dmodel and the new Z-axis coordinates. The method is simple in algorithm, is high inefficiency, is high in speed, and can effectively meet the real-time requirements of aninstant video.
