Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 , 2 shown.

[0024] A WYSIWYG video security implementation method comprises the following steps:

[0025] First, the camera is connected to a security video terminal with an embedded microprocessor (which can be implemented by using the invention patent with the application number 2008100225531 previously applied by the applicant), and the security video terminal should at least meet the following conditions:

[0026] 1. Under program control, it can receive and store the image information captured by the camera;

[0027] 2. Be able to communicate with the computer through the network in order to receive the setting commands issued by the computer;

[0028] 3. It can automatically store, analyze, and process images under program control according to computer setting commands, and automatically alarm when the setting condition...

Abstract

The invention relates to a method for realizing a WYSIWYG video safety guard, which is characterized by comprising the following steps: firstly, connecting a camera with a safety guard video terminal provided with an embedded microprocessor; secondly, displaying real-time pictures captured by the camera of a computer connected with the safety guard video terminal on a display of the computer; thirdly, using a mouse to set the real-time pictures displayed by the display; fourthly, brightening (Y+40), darkening (Y-40) or inversing (256-Y) local real-time image pixels which are corresponding to basic unit picture segments on the display of the computer; and fifthly, detecting set regions by the safety guard video terminal, and subtracting the gray values or the color values of pixels in the set regions of a front frame and a back frame to get the absolute accumulated sum so as to compare the absolute accumulated sum with a set threshold value for judgement. The method realizes the visualization set for a detecting region of a moving object in domestic safety guard products, can reduce false alarms or alarm failures, and has the advantages of wide application and easy implementation.

Description

technical field [0001] The present invention relates to a security prevention method, especially a security prevention method using video and network, specifically a WYSIWYG video security system that can focus on a certain area within the video range as required Implementation. Background technique [0002] At present, video technology has been more and more widely used in security monitoring, especially the Sky Eye project, which is widely promoted across the country. Various cameras have been spread in every corner of the city. It is very important for deterring crimes, maintaining social stability, and quickly solving cases. Played a very good role. [0003] With the continuous advancement of technology and the continuous reduction of costs, video surveillance products are not only used for city surveillance, but also widely used in office spaces, homes, key parts of shopping malls and other occasions. Most of the current security video terminals monitor the images cap...
