Problems solved by technology

[0003] However, due to the poor concentration of students, when using terminals for teaching, students are distracted during the learning process. At present, teachers basically remind students of this situation visually. However, it is difficult to observe because teachers need to use multimedia equipment when teaching. Whether every student listens carefully to the class, resulting in low teaching efficiency

Embodiment Construction

[0011] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0013] like figure 1 As shown, it is a schematic flow chart of the student monitoring method based on the line-of-sight algorithm according to the embodiment of the present invention. In this embodiment, the student monitoring method includes the following steps:

[0014] S1: The students' faces are captured in real time during the student's learning process through the student terminal, and a captured image is obtained.

[0015] In this embodiment, the student t...

Abstract

The invention discloses a student monitoring method based on a visual distance algorithm, which comprises the following steps: a student terminal captures a face of a student in real time in a studentlearning process to obtain a captured image; According to the image analysis method, the actual distance between two eyes in captured image is determined. If the actual distance value exceeds a preset threshold range, the student's face is photographed in a predetermined time to obtain a face image; eye feature data, mouth feature data and eyebrow feature data from the facial image are extracted;Eye feature data, mouth feature data and eyebrow feature data match normal eye feature data, normal mouth feature data and normal eyebrow feature data in normal expression database respectively. If any of the eye feature data, the mouth feature data and the eyebrow feature data does not match, an alarm is sent out through the student terminal to prompt the student to improve the learning concentration. The invention can automatically prompt students to listen carefully.

Description

technical field [0001] The invention relates to the technical field of multimedia teaching, in particular to a student monitoring method based on a line-of-sight algorithm. Background technique [0002] With the rapid development of electronic technology and multimedia technology, various electronic terminals have been popularized and applied in more and more fields. In many schools, terminals have been used for teaching, and students can use terminals to read e-books, watch teaching videos, or conduct classroom teaching. [0003] However, due to the poor concentration of students, when using terminals for teaching, students are distracted during the learning process. At present, teachers basically remind students of this situation visually. However, it is difficult to observe because teachers need to use multimedia equipment when teaching. To see whether each student is serious about listening to the class, resulting in low teaching efficiency. Contents of the invention ...
