Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.

[0039] The invention relates to a method for monitoring illegal network information based on video capture, and the method includes the following steps.

[0040] Step 1: Collect and display content through the information collection module.

[0041] In the step 1, the displayed content includes pictures, videos, and texts displayed on a monitor or an outdoor large screen.

[0042] Step 2: Preprocessing the collected display content.

[0043] In said step 2, preprocessing includes the following steps:

[0044] Step 2.1: Place the displayed content in the XOY plane;

[0045] Step 2.2: Adjust the edge distortion of the displayed content so that the displayed content is within the set rectangular frame;

[0046] Step 2.3: Remove noise from the displayed content.

[0047] In the present invention, i...

Abstract

The invention relates to a network illegal information monitoring method and a system based on video capture. A display content is collected through the information collection module, feature blocks are identified for the display content after preprocessing so that a threat information feature library can be compared in the next step, and after threat matching is conducted on the feature blocks, if illegal information exists, real-time alarming is conducted through the wireless communication module, and manual intervention is conducted through the network malicious information blocking module.The working principle is simple, illegal information of pictures, videos and web pages in LED large screens and public place display screens can be detected in time and can be effectively detected and shielded and blocked in time, the probability of harm caused by the illegal information is reduced, and meanwhile the security level of network information of workplaces is improved.
