Problems solved by technology

[0004] In the actual intelligent monitoring of the ATM machine, the area of ​​the card slot indicator light has been set as a shielded area, which is not within the scope of image comparison; however, the reflection caused by the flashing of the card slot indicator light on the side panel will also cause The image at the corresponding position of the background changes greatly, which leads to false alarms
[0005] However, if there is no alarm by simply setting the shielding area, there will be a risk of false positives, which directly affects the reliability of the intelligent monitoring system.

Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] In the present invention, image conversion from RGB color space to normalized color space refers to:

[0036] (1) Convert the image data of the alarm area from (R, G, B) color space to (r, g, b) color space according to the following conversion method:

[0037] r=R / (R+G+B)

[0038] g=G / (R+G+B)

[0039] b=B / (R+G+B).

[0040] Among them, using any two normalized components, the third component can be generated, for example:

[0041]b=1-r-g

[0042] (2) The two components of r and g form a normalized color space (r, g).

[0043] Any two components in the RGB color space can be selected to perform the above normalization calculation. After normalization, the purpose of reducing the color dimension and reducing redundant informa...

Abstract

The invention discloses a method for eliminating a false alarm in a monitoring system. The method comprises the following steps: carrying out color space conversion on image data of an alarm zone, thus reducing the color dimensionality; generating state description vector of the image data, wherein the state description vector is utilized as an quantitative index for describing image characteristics; and calculating the distance between the state description vector and a template vector, wherein the template vector is the state description vector of the image data of the alarm zone under a non-alarm state. The invention also discloses a device for eliminating a false alarm in a monitoring system, and the device comprises a color space conversion unit, a state description vector generation unit coupled with the color space conversion unit and an alarm judgment unit coupled with the state description vector generation unit. The invention further discloses a system for eliminating a false alarm in a monitoring system. By utilizing the method for eliminating the false alarm, the false alarm caused by light reflection on a side panel due to flickering of a faucet indicating lamp in an existing monitoring system can be eliminated and the alarm accuracy rate is improved.

Description

technical field [0001] The invention relates to the field of intelligent monitoring of ATM machines, in particular to a method, system and device for eliminating false alarms in a monitoring system. Background technique [0002] The security problem of ATM machines has always plagued the banking industry and ATM manufacturers. In order to strengthen security management, the method of camera monitoring is generally adopted, and one, two or more cameras are installed in the ATM cash withdrawal room to monitor the user's operation process. The cameras in the ATM cash withdrawal room include not only cameras for monitoring and identifying users, but also cameras for monitoring the ATM itself and the user's operation process. [0003] Artificial monitoring needs to consume a lot of manpower and financial resources, and the monitoring effect cannot be guaranteed. The importance of ATM machine intelligent monitoring system in social security is becoming more and more significant. ...
