Abstract

The invention discloses an examination behavior detection method based on an improved Openpose model and facial micro-expressions, and the method comprises the steps: arranging a camera in front of adesk, and detecting the examination behaviors of students in real time; recognizing facial information and upper body skeleton information through an artificial intelligence model, serving whether keypoints can be recognized or not and the distance between the key points as main judgment conditions, serving changes of micro-expressions as auxiliary judgment conditions, and if a certain student does not meet the condition for a period of time, judging that the examination behavior of the student is abnormal. Besides, through the video stream of one class, the possible stage of abnormal behaviors of students is found out and analyzed, and innovation and reform of teaching are realized. Interference factors are reduced by means of machine vision recognition, equipment is simplified, and a network model is further optimized by means of a residual network, weight trimming and the like. Compared with a traditional mode, self-service examination behavior detection and feedback are achieved,the test efficiency is high, the accuracy can reach 95%, and the method can be applied to general examination detection.

Description

technical field [0001] The invention relates to the technical fields of deep learning, machine vision and image processing, and specifically relates to an examination behavior detection method based on an improved Openpose model and facial micro-expressions. Background technique [0002] In recent years, artificial intelligence technology represented by deep learning has penetrated into all aspects of people's lives and has entered the stage of large-scale application. In 2017, the State Council proposed in the "New Generation Artificial Intelligence Development Plan" issued: "Use intelligent technology to accelerate the reform of talent training models and teaching methods, and build a new education system that includes intelligent learning and interactive learning." [0003] Student testing has long been a focus of educational research. In student examination activities, students are the main body of the activity, and their behavior status is a direct reflection of the ex...
