Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] A kind of detection method of remnants provided by the present invention, this method is finished by security system, and this method is as follows figure 1 shown, including:

[0043] S10, creating a background, and determining a motion target area;

[0044] The step S10 in this embodiment can be realized through the following steps S11 and S12, wherein:

[0045] S11. Obtain pictures of multiple time periods in the scene as background reference pictures;

[0046] S12. Eliminate disturbing targets in the background reference picture (for example, objects such as people or objects that do n...

Abstract

The invention is suitable for the security filed, and provides a detection method of remnants. The method comprises creating background and determining a motion object region; counting a foreground pixel existence time of the motion object region, the foreground pixels being generated into a suspicious object binary image SF when the time exceeds a time threshold, and extracting a mask M of a single object for SF through a algorithm for extracting connected regions; extracting a current-scene image of suspicious targets according to a relativity of the mask M and the SF image; and carrying out a characteristic analysis for the images of a current scene, and determining whether the objects are remnants or not according to the analysis results. The technical solution provided by the invention has the advantage of reducing the rate of false alarm.

Description

technical field [0001] The invention belongs to the field of security protection, and in particular relates to a method and system for detecting remnants. Background technique [0002] In the field of security, the detection of remnants can effectively prevent terrorists from planting bombs, poisonous gas and other dangerous goods, improve the safety of public places, timely discover the luggage left by passengers and reduce the loss of passengers, so it plays an extremely important role in the field of security. Existing methods for detection of remnants in the field of security mainly include background difference technology (the technology of subtracting the current image from the background image) to detect targets that stay too long, compare the detected targets with the current scene, and analyze whether they are Remnants. [0003] In the process of realizing the prior art, it is found that the technical solution of the prior art has the following problems: [0004] ...
