Abstract

The invention discloses a teaching management method and device, and the method comprises the steps: firstly, collecting a plurality of standard face grey-scale images of a plurality of persons in real time; obtaining a plurality of feature vectors according to the convolutional neural network and the plurality of standard face grayscale images; secondly, inputting the plurality of feature vectorsinto a classifier to determine a plurality of expression classification results; wherein the expression classification result comprises pleasure, convulsion, aversion, anger, fear and tragedy; then,calculating expression statistical data according to a plurality of expression classification results; finally, determining classroom feature information according to expression statistical data in apreset time period; wherein the class feature information comprises student attention, student participation degree and course difficulty degree. According to the invention, the accuracy and robustness of face expression detection are improved, the recognition precision and compatibility of face expressions in teaching management are improved, and the teaching quality of teachers and the learningefficiency of students are improved.

Description

technical field [0001] The invention belongs to the technical field of face recognition, and in particular relates to a teaching management method and device. Background technique [0002] The facial expressions of the human body can reflect the real internal emotions of the human body, and then the emotional fluctuations in the human body can be judged according to the changes in the human body's expressions; however, due to the variability and complexity of the emotional activities in the human body, correspondingly, the human body's Facial expressions also have a variety of diversity; in the process of daily communication, the two parties in the communication can judge the emotional information of the human body in real time through the changes of each other's facial expressions. The problem of communication barriers occurs; facial expressions play a key role in reflecting the inner emotional information of the human body, and relevant technical personnel gradually begin ...
