The invention relates to the technical field of dictionary learning, and aims to provide a face recognition method for structural incoherent projection dictionary pair learning, which comprises the following steps of S1, setting parameters, establishing a structural incoherent projection dictionary model, and executing S2; s2, inputting a training sample, optimizing the incoherent projection dictionary model, and executing S3; s3, inputting a to-be-recognized face image to the incoherent projection dictionary model, extracting features of the to-be-recognized face image, and executing S4; s4,enabling the incoherent projection dictionary model to calculate a coding coefficient matrix of face features of the face image to be recognized according to the features of the face image to be recognized, and executing S5; and S5, inputting the incoherent projection dictionary model into a classifier according to the coding coefficient matrix and the corresponding category label information to obtain a final classification result. The face recognition method has the advantages that the face recognition speed is increased while the face recognition precision is ensured.
