Student state evaluation method and system based on posture recognition

Abstract

The invention discloses a student state evaluation method and system based on posture recognition. The method comprises the following steps: obtaining classroom videos of all students in a classroom and teaching videos of teachers in real time; intercepting a plurality of video clips from the classroom video at intervals; wherein each video clip is associated with a time label; segmenting single-person video clips of all students in the video clips; for any one single video clip, playing the video clip; recognizing personal information of students in the single video clip by utilizing a face recognition algorithm, recognizing postures of the students in the single video clip based on a posture recognition model, and outputting classroom performance evaluation of each student and time labels corresponding to all postures which do not meet classroom requirements in each student posture time set. The postures of all the video clips of the students are scientifically integrated to evaluatethe classroom performance of the students, the time labels corresponding to the postures which do not meet the classroom requirements of the students are recorded, the students can conveniently review missing knowledge points in a targeted mode after class, and teachers can also improve the teaching mode according to the postures.

Description

Technical field [0001] The present invention relates to the field of intelligent education, in particular to a method and system for evaluating student status based on gesture recognition. Background technique [0002] With the maturity of image technology, artificial intelligence technology is widely used in classroom teaching. The courses in colleges and universities are heavy and the class hours are limited. Teachers need to complete the teaching tasks in a relatively short time. However, the phenomenon of college students skipping classes, falling asleep during class, and wandering from time to time. In order to ensure the quality of classroom teaching, college teachers often interact, such as asking students to answer questions on the spot, maintaining classroom discipline, reminding sleepy and distracted students, and recording students' classroom performance. This undoubtedly increases the difficulty of teaching and reduces the continuity of classroom teaching. , Affecti...
