Abstract

The invention provides a cheating recognition method and device. The method comprises the steps of firstly obtaining a first examination video, wherein the first examination video is a video recordedfor an examination behavior of a first examinee; extracting a feature vector corresponding to each frame of image in the first examination video; wherein the feature vectors comprise information representing whether eyes are detected in the images or not and information obtained based on the positions of pupil centers of the eyes when the eyes are detected, and the feature vectors corresponding toall the images contained in the first examination video are combined to obtain a first feature vector sequence. Inputting the first feature vector sequence into a cheating recognition model, obtaining the output of the cheating recognition model, and determining that the first examinee cheating when the output of the cheating recognition model represents that the first examinee has a cheating behavior. The invention further provides a training method and device of the cheating recognition model, electronic equipment and a medium.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and more specifically, to a cheating recognition method and device, a cheating recognition model training method and training device, an electronic device, and a computer-readable storage medium. Background technique [0002] At present, browser window anti-switching technology and camera recording technology are mainly used in online examinations to confirm the examinee's identity and prevent plagiarism. However, the following methods of cheating cannot be prevented: another computer can be used to assist in searching for answers, and after obtaining the answers, input them into the examination computer, resulting in the inability to judge whether the person's true knowledge level. [0003] At present, the mainstream technology mainly judges whether the examinee has cheating behavior according to the posture characteristics of the people in the examination video. But can't monitor ex...
