Abstract: A method for quickly generating a number of face images under complex illumination includes the steps: providing at least one two-dimensional face image; creating a number of key points on the two-dimensional face image in order to obtain a three-dimensional face shape; replenishing the two-dimensional face image with an invisible portion; performing a texture mapping on the three-dimensional face shape in order to obtain a three-dimensional face; placing the three-dimensional face at an origin position of a three-dimensional coordinate and separately rotating the three-dimensional face with three coordinate axes as a center, and setting up different light sources in different coordinates of the three-dimensional coordinates to complete light rendering; and placing the three-dimensional face at the origin position of the three-dimensional coordinate and separately rotating the three-dimensional face with three coordinate axes as the center, and photographing the three-dimensional face from different angles in
