A data screening method for a security monitoring system

Abstract

Disclosed in the present invention is a data screening method for a security monitoring system, comprising the following steps: (1) sending screen images to a data screening processor; (2) performing standard deviation standardization on pixel points; (3) calculating a comparative reference function value of each image; (5) calculating an image decision threshold ND, if δ(i, j) is greater than ND, taking the image as a warning image, and letting Q(i, j) = 1; otherwise, taking the image as a normal image and letting Q(i, j) = 0; and (6) determining whether the image is sent to a confirmation person according to an output result of Q(i, j). The present invention not only can automatically process and screen image data information from the security monitoring system, but also can automatically implement automatic identification and determination of the security monitoring data; by performing data processing of pixel points on the image information, and carrying out calculation and analysis on the basis of multiple functions, the image security information can be automatically identified, so that the automatic screening of data monitoring is ensured, and the security effect is improved.

Description

technical field [0001] The invention relates to a data screening method of a security monitoring system, belonging to the technical field of security monitoring data processing. Background technique [0002] At present, with the continuous development of computer information and monitoring cameras, the security monitoring system is composed of camera, transmission, control, and display. The effect is the best. At present, security monitoring is the physical basis for real-time monitoring of key departments or important places in various industries. Management departments can obtain effective data or sound information through it, and monitor and remember the process of sudden abnormal events in time to provide efficient , Timely command and altitude, deployment of police forces, handling cases, etc. With the rapid development and promotion of current computer applications, a powerful wave of digitization has set off all over the world, and the digitization of various device...

Problems solved by technology

[0003] At present, the security monitoring system lacks a data processing method for effectively processing monitoring information, which makes it difficult to automatically distinguish special data even if there is an abnormal monitoring. Therefore, with the continuous development of computer processing technology, how to realize the monitoring image Carry out data analysis and automatic identification, and identify image information that may be abnormal, so as to focus on storage or monitoring, and improve the security of monitoring
