Abstract

The embodiment of the invention provides a motoring treating method and a device for a video of an examination room. The method comprises the steps of: firstly, intelligently analyzing a motoring video image in the examination room; judging whether the video image has an examination paper image or not; controlling the cradle head operation of a network management system if the examination paper image exists; pulling the video image to the position from which the examination paper image cannot be seen; and covering areas with the examination paper image at the same time. In this way, the problem on using a zoom camera to replace a wide-angle fixed focus camera can be solved; and the illegal abuse of the zoom camera in an examination process is effectively avoided.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for monitoring and processing examination room video. Background technique [0002] At present, the rapid rise of digital technology has expanded the imagination of people to develop more automatic technologies. For example, in the field of image processing, automatic object detection and recognition technology has attracted more and more attention, and video is interactive on the time axis. A collection of associated series of images, and the detection of video is also based on image processing and analysis. [0003] For example, in the remote electronic inspection command system for educational examinations, most of the cameras used are fixed-focus wide-angle cameras. This is to prevent someone from zooming in on the screen during the examination process to the content of the test paper, thereby stealing the secret of the test paper. However, the fi...
