Abstract
Disclosed are an augmented reality-based coloring method and apparatus, an electronic device and a storage medium. The method comprises: acquiring three-dimensional mesh information of a human face, and acquiring position coordinates and texture coordinates of respective vertices of a target portion of the human face based on the three-dimensional mesh information of the human face; constructing a three-dimensional mesh of the target portion according to the position coordinates of respective vertices of the target portion, and determining a normal line of each vertex in the three-dimensional mesh; and coloring the target portion based on the position coordinates, the texture coordinates and a normal line of each vertex in the three-dimensional mesh, a preset shading map of the target portion, and a target RGB value of the target portion, thereby improving the stereoscopic impression and the sense of reality of coloring, and improving the user experience.
