Embodiment 1

[0066] This embodiment provides a method for evaluating students' online learning status based on facial recognition, please refer to figure 1 , the method includes:

[0067] S1: Obtain the student's face image, student's answer to the question and student information;

[0068] Specifically, in the process of students starting the online class, the students turn on the computer's camera to obtain the students' facial information. The collected facial images, students' answers to questions and student information are uploaded to the server as input, and the relevant modules obtain these input information.

[0069] Among them, the video stream is used to monitor the students' listening status. In the specific implementation process, each online class can be divided into different stages according to the time for students to answer questions. The situation and student information are uploaded to the server. In the specific implementation process, considering that the learning ...

Embodiment 2

[0137] Based on the same inventive concept, this embodiment provides a system for evaluating students' online learning status based on facial recognition. Please refer to Image 6 , the system consists of:

[0138] The information acquisition module 201 is used to acquire the facial image of the student, the student's answer to the question and the student's information;

[0139] The student's answering question evaluation module 202 is used to obtain the student's answering question result according to the comparison between the student's answering question and the reference answer;

[0140] Comprehension degree identification module 203, which is used to standardize the collected facial images into consistent picture information and then input them into the trained micro-expression recognition convolutional neural network model to obtain the student's online class listening comprehension status;

[0141] Concentration recognition module 204, is used for carrying out face re...

Embodiment 3

[0150] Based on the same inventive concept, this embodiment provides a computer-readable storage medium on which a computer program is stored, and when the program is executed, the method described in Embodiment 1 is implemented.

Abstract

The invention discloses a student online class learning state evaluation method based on facial recognition. The method comprises the steps of obtaining a facial image of a student, a student questionanswering situation and student information; obtaining a question answering result of the student according to the comparison condition of the question answering condition of the student and a reference answer; standardizing the acquired face image into consistent picture information, and inputting the picture information into a trained micro-expression recognition convolutional neural network model to obtain an online lesson listening comprehension degree state of the student; obtaining the concentration degree of the student according to the comparison condition of the ratio of the face length and width of the student to a preset standard face length-width ratio and the comparison condition of the eye opening height of the student to a preset standard face eye opening height; and takingthe question answering result of the student, the online lesson listening comprehension degree state and the concentration degree as the online lesson learning state evaluation result of the student.According to the method, the recognition efficiency can be improved, and the evaluation effect is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for evaluating students' online learning status based on facial recognition. Background technique [0002] At present, colleges and universities are gradually introducing online learning methods for reasons such as saving teaching expenses, saving manpower and material resources, and enriching teaching content. Students can learn knowledge and skills by watching video and audio online through electronic devices and the Internet. [0003] In the process of implementing the present invention, the inventor of the present application found that the method of the prior art has at least the following technical problems: [0004] While online classes are convenient for teachers and students, there is also the problem that students cannot be supervised due to conditions. Just watching the video without the teacher-student interaction process similar to the...
