Problems solved by technology

However, when the students are in the area where the head is facing up, the eyes are open, and the line of sight is scattered outside the computer screen, these traditional methods will have false detections, resulting in low detection accuracy and not convincing enough

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] like 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 de...

Abstract

The invention discloses an attention detection method with the combination of sight detection. The method includes face detection, eye closing detection, eye sight detection and head deflection detection, images are captured through cameras, and eye closing characteristics, head deflection characteristics and sight characteristics of students in each frame are analyzed to determine whether the attention of the students is focused. According to the attention detection method, with the combination of the sight detection method, the problems that the students are in head emmetropia, eyes are open, and the sight is in an area outside a computer screen are solved, the concentration condition of the attention of the students during online learning can be detected, the method is advantaged by high accuracy, good stability and high reliability, and the method is scientific and practical.

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...
