Problems solved by technology

[0006] Among the existing technical solutions, the first and second ones both rely on a large amount of human participation and lack practical application effects
However, the third solution currently on the market lacks scientificity in the calculation and analysis after data collection; in practical applications, it lacks correlation analysis of data applications and is systematically lacking.

Embodiment 1

[0056]like figure 1 As shown, the present embodiment provides a real-time concentration analysis method based on face recognition technology, comprising the following steps:

[0057] S1: Use the camera to collect the face video of the students in class;

[0058] The number of the cameras is set to 1-2 according to the size of the classroom. In this embodiment, the number of cameras used is 2, and the deployment positions are located on both sides of the center of the classroom, which can collect all face images in the covered area. Let the deployment height of the camera be ha, the deployment height of the camera refers to the height difference between the camera and the average height of the classroom face, and the coverage length of the camera is la, then ha and la satisfy:

[0059] arc tan(ha / la)=10°~arc tan(ha / la)=30°.

[0060] The deployment of the above ha and la can ensure the best video capture effect.

[0061] S2: According to the face recognition algorithm, extra...

Embodiment 2

[0075] A real-time concentration analysis method based on face recognition technology, including:

[0076] Camera: used to collect the face video of students in class;

[0077] Face feature extraction module: used to extract the face area in the video image according to the face recognition algorithm, and extract the features of the face area;

[0078] Concentration evaluation module: it is used to judge the number of students who raise their heads according to the characteristics of the extracted face area, and set the concentration of students to A or B according to whether the students raise their heads, where A≠B, A means high concentration, and B means concentration low degree;

[0079] Concentration analysis and calculation module: According to the binomial distribution principle of statistics, that is, repeating n times of Bernoulli experiments, the average probability of the overall concentration of students is obtained, and the confidence interval of the average prob...

Abstract

The invention provides a real-time concentration analysis method based on the face recognition technology and a real-time concentration analysis system based on the face recognition technology. According to the method, the personnel face image under the current video monitoring environment is sampled and analyzed through the face recognition technology of AI (artificial intelligence) of the information technology field so that the big data acquisition standard of student concentration can be established under the state of no interference in the classroom teaching process, the concentration canbe judged and the objective and real data result can be provided for learning condition analysis of classroom teaching through the scientific big data algorithm. The result is applied to the technical field of education and student concentration analysis of the whole class can be completed by using the principle of statistics and the algorithm. The learning condition of the student in the classroom teaching process can be accurately analyzed through other relevant data like classroom teaching process analysis and face recognition accurate matching, etc.

Description

technical field [0001] The present invention relates to the fields of information technology and education technology, and more specifically, to a real-time concentration analysis method and system based on face recognition technology. Background technique [0002] In the existing technical solutions, there are three methods for classroom learning situation analysis: [0003] One is to record directly through expert observation without using technical means, focusing on the subjective impression of the attendees, which is a fully manual method; [0004] The second is to collect data by using auxiliary equipment. This type of auxiliary equipment requires students to manually touch the terminal to record, which is semi-automatic; [0005] The third is to use relatively new technology to analyze and judge through face recognition. [0006] Among the existing technical solutions, both the first and the second ones rely on a large amount of human participation and lack practica...
