Problems solved by technology

However, this technology is sometimes tricked by some students when the person is required to answer the answer. They will adjust the direction of the camera to the side of the screen. The student himself sits on the side of the screen, and the test taker faces Answering questions on the screen, in this way, although the system captures the student himself, the real answerer is not the student himself, but the test taker who sits facing the screen

Embodiment Construction

[0026]Place the display screen on the desktop, and place the camera in the middle of the upper frame of the display screen; start the remote test monitoring software, and display the picture taken by the camera on the screen; the remote test monitoring software displays a large area in the middle of the top of the display screen Rectangular color block; place a rectangular mirror with a length of 10 cm and a width of 6 cm on the desktop directly in front of the camera; candidates sit directly in front of the camera and behind the rectangular mirror; adjust the distance between the mirror and the camera, the height of the mount and the reflection Angle, to ensure that in the picture captured by the camera, the rectangular color block in the middle of the upper part of the display screen appears, and at the same time, the candidate's face will not be blocked. Obviously, when the left and right sides of the rectangular color block in the picture captured by the camera have the sam...

Abstract

The invention discloses a method for preventing cheating caused by side-position shooting of a camera in a remote examination. The method is characterized by comprising the following steps that a monitoring system is composed of a remote monitoring control, a camera, a computer screen for displaying remote monitoring software and a mirror; a specific pattern of the remote monitoring software is displayed on a computer screen, wherein the specific pattern can be the whole computer screen capable of distinguishing the remote monitoring software, or a software interface of the remote examinationmonitoring software; or colors, lines, patterns or pictures on a certain part of an interface of the remote examination monitoring software; the orientation of the camera lens is kept consistent withthat of a computer screen, the mirror is placed opposite to the screen, and when a specific pattern appears in the mirror of a picture shot by the camera and left-right deformation of the specific pattern is consistent, it can be judged that the orientation of the camera lens is consistent with that of the screen.

Description

technical field [0001] The present invention belongs to the field of image recognition using artificial intelligence. Background technique [0002] With the application of artificial intelligence in the field of image recognition, a classic technical problem, how to apply artificial intelligence to identify cats in various photos, already has a variety of reliable technical solutions. Based on this technology of artificial intelligence plus image recognition, such a remote examination application has appeared, using a camera installed on the computer screen to monitor the students sitting in front of the screen to ensure that the students themselves are taking the test without the assistance of others , if it is found that the student is not taking the test, or is assisted by others, the system can suspend the test or record the student's cheating behavior. This kind of application has been proven in the market that it is completely feasible for some exams that require a lo...
