Hello! As you know, we are a provider of video surveillance at various significant events, including the Unified State Exam.
In this post, we want to tell you about our video surveillance and video analytics platforms, how exam monitoring works, what difficulties there are, and how our algorithm helps to detect violations in exams.
Usually special people - observers follow the course of the exam. They note on the video surveillance portal smotriege.ru the suspicious behavior of the USE participants and submit the detected violations to Rosobrnadzor for moderation. If the moderators believe that the violation really happened, then it is passed on to the examination point for testing (PES). PPE employees check each such appeal and decide what to do with the offender. For example, remove from the exam if he used a phone or cheat sheet.
2020 was no exception, and online observers followed the state attestation. True, this time they had an assistant - a specially trained algorithm. It analyzes the sequence of images that come from video cameras in real time or from archive records, and finds among them possible violations: the use of cheat sheets, a telephone and other devices.
Video analytics technology “watched” the video stream from the classroom online, and between exams - archived videos from offline. In comparison, one observer can watch a maximum of four audiences at the same time, and the algorithm can process videos from more than 2000 audiences in one exam day.
