Problems solved by technology
However, since the whole process of online learning is realized by students facing the screen, this makes it difficult for students to maintain a state of concentration at all times during the whole process and is prone to distraction, which will affect the efficiency and quality of students' online learning , and the existing technology cannot effectively and accurately judge which state of the student belongs to the state of concentration or distraction, which cannot reliably and quantitatively judge the quality state of the student's online learning, which is not conducive to improving the quality of online learning. efficiency and quality

The invention provides an online learning quality evaluation method and system, and the method comprises the steps: photographing the face of a student so as to obtain a corresponding face image, determining the eye opening and closing state and eye sight direction state of the student according to the face image, thereby determining the concentration state of the student in an online student process. According to the method, a quantitative judgment result about the learning concentration state of the student can be directly obtained through a series of image processing calculation from the shot face image, so that the online learning quality state of the student can be reliably and quantitatively judged, and the online learning efficiency and quality can be improved.
Description
technical field [0001] The invention relates to the technical field of intelligent education, in particular to an online learning quality evaluation method and system. Background technique [0002] At present, online learning is realized by students watching corresponding courses on the screen of the device terminal and interacting with teachers, which can facilitate students to study courses anytime and anywhere on different occasions, thereby improving the convenience of students' course learning and flexibility. However, since the whole process of online learning is realized by students facing the screen, this makes it difficult for students to maintain a state of concentration at all times during the whole process and is prone to distraction, which will affect the efficiency and quality of students' online learning , and the existing technology cannot effectively and accurately judge which state of the student belongs to the state of concentration or distraction, which ...
