Embodiment Construction

[0067] Such as figure 1 As shown, a facial expression recognition method suitable for classroom teaching, the facial expression recognition method includes the following steps:

[0068] Step 1: Use the camera equipment to record the classroom situation in real time, and obtain the real-time video information of the classroom; the camera equipment is a surveillance camera;

[0069] Step 2: Process the real-time video information, obtain the student's facial image information, and judge the disappearance time of the facial image information;

[0070] S1: When the disappearance time of the student's facial image information is greater than the preset time value T1, it is determined that the student is in a state of mind-wandering, and the student's mind-wandering rate is counted; the specific statistical steps are as follows:

[0071] SS1: Obtain the total time of mind-wandering students in a class;

[0072] SS2: Divide the total time of the student's mind-wandering by the tota...

Abstract

The invention discloses an expression recognition method suitable for classroom teaching, and the method comprises the following steps: carrying out the real-time recording of the condition of a classroom through employing a camera device, and obtaining the real-time video information of the classroom; Processing the real-time video information to obtain student face image information, and judgingthe disappearance time of the face image information; When the disappearance time of the student face image information is greater than a preset time value T1, judging that the student is in a distraction state, and counting the distraction rate of the student; By arranging the camera equipment, real-time conditions in a classroom can be monitored, the camera equipment is combined with the processing device to detect that the face is appearing time, and when the face of a certain student does not appear time exceeding a preset value, the student can be automatically judged to be in a distraction state; On the contrary, it is considered that normal pause occurs, and head lowering notes and other activities are obtained; By means of the method, whether the student is distracted or not during class can be effectively detected.

Description

technical field [0001] The invention belongs to the field of classroom teaching, and relates to an expression recognition technology, in particular to an expression recognition method suitable for classroom teaching. Background technique [0002] Expression recognition refers to the separation of specific expression states from a given static image or dynamic video sequence, so as to determine the psychological emotion of the recognized object. [0003] With the rapid development of computer technology and artificial intelligence technology and related disciplines, the degree of automation of the whole society is constantly improving, and people's demand for human-computer interaction similar to the way people communicate is becoming stronger and stronger. If computers and robots can understand and express emotions like humans, it will fundamentally change the relationship between humans and computers and enable computers to serve humans better. Expression recognition is th...
