Description

Item security inspection method and system based on item identification tag

technical field

Embodiments of the present invention generally relate to the field of security inspection, and in particular, relate to a method and system for performing security inspection on items based on item identification tags.

Background technique

In the field of security inspection, after the security inspection machine performs X-ray scanning on the items, the security personnel will identify the X-ray images. If any suspicious items are found, the corresponding X-ray images will be marked with suspicious marks, and the package will be opened in the next step. The re-inspector at the station conducts an unpacking inspection, and then performs an X-ray scan again, and records the inspection results on the re-inspection image. At present, re-inspectors may face one of the following three situations:

(1) "No X-ray machine for re-inspection": that is, there is no independent X-ray machine for re-inspection at the unpacking station, and there is no independent operation interface. The X-ray machine scans the items again; this technology is only suitable for situations where the security requirements are relatively low;

(2) "Incomparable information": the unpacking station has an independent re-inspection X-ray machine and operation interface, but the operation interface is similar to the initial inspection X-ray machine, only the X-ray image of the item being re-inspected, and cannot be seen Corresponding initial inspection X-ray images, at the same time, there is no image queue of items to be re-inspected in the working interface of the unpacking station; this technology cannot establish the corresponding relationship between the initial inspection image and the re-inspection image, which is not conducive to the re-inspector to view suspicious mark;

(3) "Associated deployment of initial inspection machine and re-inspection machine": that is, when deploying security inspection channel equipment, the initial inspection X-ray machine and the re-inspection X-ray machine are deployed independently, but the two machines are interconnected at the software level. The initial inspection X-ray machine checks and marks suspicious images, and automatically sends them to the re-examination X-ray machine to generate a queue of images to be re-examined. This technology requires the modification of the communication hardware of the two X-ray machines and the software modification of information sharing. For most cases where two independent X-ray machines from different manufacturers have been deployed in one security inspection channel , the transformation cost is higher, and the risk of failure is greater.

Exemplarily, at least one of the second to fifth detection devices may include or employ a radio frequency identification card reader for reading the item identification tag.

The fourth item identification information is wired or wirelessly transmitted to the workstation 40, and the workstation 40 can establish a multi-unit configuration based on the matching of the fourth item identification information with the first item identification information and/or the second item identification information and the first data. In the queue of images to be re-inspected, each unit may include the corresponding initial-inspected image of the suspected item and the identity information of the inspected person associated with it. The workstation 40 may select, from the queue of images to be re-examined, the primary-inspection image associated with the identity information associated with each re-examination image for comparison processing based on the third data. Specifically, the workstation 40 can determine whether the fourth item identification information matches the first and/or second item identification information, such as whether the fourth item identification information is the same as the first and/or second item identification information or contains the same information as the first item identification information. and/or the second item identification information is the same and represents the number of the identified item, container or luggage case. After determining that the fourth item identification information matches the first and/or second item identification information, the workstation 40 compares the identification information contained in the first data with the corresponding item and/or the storage device or luggage bag containing the item. The corresponding relationship among them is used to obtain the identity information of the person to be re-inspected, and the identity information and the initial inspection image of the corresponding item are added as a unit to the queue of images to be re-inspected. It can be seen that the arrangement of the fifth detection device 35 can facilitate the work station to establish a luggage image queue to be re-inspected, and can save the inspected person from actively swiping his ID card once, that is, there is no need to re-inspect or identify the inspected person when the item is re-inspected ID card.

After generating the third data indicating that the re-examination image is associated with the identity information, the workstation 40 can select the initial inspection image associated with each identity information from the queue of images to be re-examination according to the identity information, and based on the first, second The re-inspection image and the initial inspection image associated with the same identity information are compared with the third data to determine whether the item associated with the identity information contains prohibited content and/or locate the position of the prohibited content in the item. The workstation 40 may include a display device 41, which may display the identity information of the inspected person, the initial inspection image/real photo of the item, the image queue to be re-inspected, the re-inspected image, and/or the comparison result.
