The invention provides a millimeter wave image-based face recognition method and system. The method comprises the steps of performing size processing on a millimeter wave image to obtain a processed image consistent with a registered image in a face image retrieval library in size; extracting face features of the processed image to establish feature extraction mapping; and comparing the feature extraction map with a pre-established preliminary feature map of the registered image to obtain a matched preliminary feature map. According to the invention, face recognition can be realized based on the millimeter wave image generated by the millimeter wave security check imaging system.
