The invention discloses a face image reversible geometric normalization method facing overall characteristics analysis. A method based on secondary affine transformation is adopted. Firstly global affine is carried out which means that global rotation, zooming and cutting are carried out on a face image according to a standard structure definition of a face, such that in an input face image, coordinates of two eyes are at a same horizontal line, a two eye center distance is subjected to normalization according to a parameter d of a standard structure, and transverse and longitudinal proportions of the face are consistent with the standard structure. The image is cut into a magnitude of 2d*2d. Then geometric position normalization is carried out on a mouth area through a local affine transformation needle. Finally by utilizing image edge fusion, a standard geometric normalization face image is formed. An inverse normalization process is that according to a transformation parameter, a standard structure face image is recovered to a geometric structure characteristic before geometric normalization through secondary affine inverse transformation such that personalized topology structures of different face characteristic points are maintained. The face image which goes through geometric normalization can be used for face analysis based on an overall characteristic, such as super resolution reconstruction of the face image, face recognition, and the like.
