An illumination detection method comprises acquiring a face image to be detected and a three-dimensional face mesh template; deforming the three-dimensional face mesh template according to the face image to obtain a reconstructed face mesh model; according to the deformation positions, in the reconstructed face mesh model, of key feature points in the three-dimensional face mesh template, determining the brightness of feature points, corresponding to the key feature points, in the face image; and according to the relationship between the predetermined brightness of the key feature points and the illumination, and the brightness of the feature points, corresponding to the key feature points, in the face image, determining illumination information of the face image.
