The invention provides a multi-pose face recognition method based on MB-LBP features and a face energy diagram. According to the method, a multi-pose face image training library is established, and after size normalization processing is carried out on face images, a face mean value energy diagram and a variance energy diagram of the training library are established; MB-LBP feature extracting is carried out on the obtained face mean value energy diagram and the variance energy diagram, and the MB-LBP features are stored as matching library information; when face detection is carried out, the face images are detected and face regions are extracted, and size normalization processing is carried out on the images of the face regions to obtain standard face images; MB-LBP feature extracting is carried out on the standard face images; finally, classification and recognition of multi-pose faces are completed by adopting a nearest neighbor classifier. According to the multi-pose face recognition method based on the MB
