Embodiment Construction
[0032] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] The attention detection method of the present invention combines line of sight detection. The detection scene is that students are sitting in front of the computer screen, and they can select images from ordinary cameras or videos through the mouse, and can detect the current number of people, the current frame number, face coordinates, head Angle of deflection, percentage of eye closure, and direction of gaze.
[0034] Such as figure 1 As shown, the specific implementation process of the attention detection method of the present invention is as follows: firstly, the image is captured by the camera; then the face detection is performed, and when the face is not detected when the threshold is continuously exceeded for a certain period of time, it is...

The invention discloses an attention detection method that integrates line of sight detection. The method includes face detection, human eye closure detection, human eye line of sight detection, and head deflection detection. The camera captures pictures and analyzes each frame. Eye closure characteristics, head deflection characteristics and line of sight characteristics of middle school students are used to judge whether students are focused or not. The present invention solves the problem that the students are facing the head squarely, the eyes are open, and the line of sight is outside the computer screen by integrating the line of sight detection method; the present invention can detect the concentration of students' attention in online learning, so the method of the present invention is scientific, practical, It has the advantages of high accuracy, good stability and strong reliability.
Description
technical field [0001] The invention belongs to the technical field of on-line teaching state detection, and in particular relates to an attention detection method fused with line-of-sight detection. Background technique [0002] Online education is becoming more and more popular with the development of the network, and it is of great significance to determine the learning status of students in this mode. Attention detection is an important part of judging students' learning status in online education. It uses changes in the characteristics of faces and facial features, or uses brain wave detection or ECG frequency to judge whether attention is concentrated. Compared with other non-computer vision attention detection methods, attention detection methods based on computer vision have the characteristics of non-contact, strong real-time performance, high reliability, strong adaptability, and low cost. [0003] The attention detection method based on computer vision mainly acq...
