Security check method and device based on person-package association

Abstract

The invention discloses a security check method and device based on person-package association. The method comprises the following steps: generating first associated data of a video, a passenger faceimage and a package shape image; generating second associated data of the package shape image and a package X-ray image; generating set associated data of the video, the passenger face image, the package shape image and the package X-ray image; comparing the X-ray image of the package with pre-stored information, and judging whether a contraband exists in the package or not; and stopping alarmingtill that an inspection result is recorded. By using the security check method and device based on person-packet association, the set associated data of the video of the package placed by a passenger,the passenger face image, the package shape image and the package X-ray image can be obtained, problems that the packages discarded by the passengers are difficult to find in time and difficult to trace in a later period when the passengers leave, reject, escape from inspection, miss inspection or mistakenly take or miss the packages are solved, and the method and the device are very worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a security inspection method and device based on person-bag association. Background technique [0002] In the prior art, the application number is "201910588858.7", a method of corresponding security inspection between passengers and carry-on luggage based on image recognition. First, the security check basket and the security check tray are numbered with X-ray developing materials; When in the security inspection basket or security inspection tray, obtain passenger information and extract the basket and tray numbers through the camera, and bind the number and passenger information; when the passenger luggage passes through the security inspection machine, extract the number information from the image of the security inspection machine, and The information matches the passenger information, which realizes the correspondence between passengers and their carry-on luggag...

AI Technical Summary

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above method requires passengers to put their personal packages into the security inspection basket, and then bind and cache the security inspection basket number and passenger information. Many, one is that the security inspection basket is only suitable for small parcels, and it is not only difficult to place large parcels such as suitcases, but also cumbersome and heavy to take and transfer. The second is that the external basket number is bound to the passenger information Rather than a specific piece of luggage inside, there is no one-to-one correspondence between luggage and passengers. If a piece of luggage in the basket is exchanged, missed or lost, not only the corresponding information is wrong, but it is also difficult to trace back later. The third is that the security inspection basket needs to be operated for recycling, and its purchase, use, maintenance and other management costs are high, which increases operating costs. Fourth, passengers need to place their luggage in the security inspection basket in turn, and the security inspection efficiency is also low; 2. Once a contraband is detected, the passenger carrying the contraband may notice the abnormality and will abandon the package and leave or deny that the package is his own. Using the above method, the prior association between the package and the passenger cannot be achieved, which will bring difficulties to the traceability work ;3. During the security check process, there may be cases of missed checks, escaping checks, or mistaking or missing packages after security checks, which may cause mismatches between people and packages. The effect of the method is relatively limited
