Classroom monitoring method and device, computer device and storage medium

Abstract

The invention discloses a classroom monitoring method and device, a computer device and a storage medium. The classroom monitoring method comprises the steps of collecting a first target face image according to a first time interval, inputting the first target face image into an expression recognition model, and obtaining a first recognition result; if the first recognition result is abnormal, sending a first prompt message to the monitoring terminal; adding a first target face image whose first recognition result is an anomaly to a focus queue, the focus queue including a focus person identification; collecting a second target face image according to a second time interval and a focus person mark in a focus attention queue, inputting the second target face image into the expression recognition model to obtain a second recognition result; if the second recognition result is abnormal, sending a second prompt message to the monitoring terminal. The classroom monitoring method not only ensures the classroom monitoring, but also reduces the calculation of data collection and identification, and improves the overall efficiency.

Description

technical field [0001] The invention belongs to the field of image processing, and more specifically relates to a classroom monitoring method, device, computer equipment and storage medium. Background technique [0002] In the teaching classroom, when the current teacher is in class, he may not be able to observe that some students are wandering in their thoughts and did not listen carefully to the class, which may cause students to miss some important knowledge points. With the rapid development of image recognition technology, some technologies are currently trying to use expression recognition technology to obtain real-time expressions of middle school students in the classroom, and use the camera to collect images to analyze the collected images in the camera. If there are multiple faces, each face All facial expressions and movements are analyzed to determine whether the student is currently in a state of desertion. However, due to the long duration of the class and th...
