The present invention provides a system and method for multi-dimensional emotion discrimination of a face image based on a neural network. The system comprises: a face location module configured to identify a face region in an image to be detected and extract a face image in the image to be detected; a feature extraction module configured to extract emotion features of the face image; an identification module configured to identify the emotion features to obtain emotion information; and an output module configured to output the emotion information. The system and method for multi-dimensional emotion discrimination of the face image based on the neural network can adapt different face angles, skin colors and face shapes to extract emotion feature vectors and represent the multi-dimensional emotion to which the face image belongs so as to improve the accuracy of face emotion analysis.
