Embodiment 1

[0050] Such as figure 1 As shown, an X-ray security inspection method based on multi-camera fusion, the specific steps are as follows:

[0051] S1. When the passenger puts the luggage on the X-ray security inspection machine, the time point is Ta, and the infrared sensor is triggered to detect that there is luggage placed. The first image collection terminal A at the security check entrance collects the picture information of the passenger and the luggage at this time Ta. And capture passenger facial image information A1 and baggage external image information A2, and send information storage request;

[0052] S2. The analysis server receives the storage request from the first image acquisition terminal A, establishes a data storage space corresponding to the time point Ta, stores the time point information and generates the address information of the data storage space, and stores the passenger facial image information A1 and luggage The external image information A2 generate...

Embodiment 2

[0073] Such as Figure 5 As shown, an X-ray security inspection device based on multi-camera fusion includes a first image acquisition terminal A, an X-ray security inspection device, a second image acquisition terminal B, an analysis server, a display, and an audible and visual alarm;

[0074] The X-ray security inspection instrument is used to generate X-ray image information A3, and an infrared sensor is arranged at the entrance of the X-ray security inspection instrument to detect the placement of passenger luggage, and trigger the image acquisition terminal to work with the X-ray security inspection instrument;

[0075] The first image collection terminal A is used to collect the luggage placed into the X-ray security inspection machine, at the time point Ta, it includes the picture information of the passenger and the luggage, and captures the facial image information A1 of the passenger and the external image information A2 of the luggage;

[0076] The second image coll...

Abstract

The invention discloses an X-ray security check method and device based on multi-camera fusion. When a checked passenger places luggage on an X-ray security check instrument, the passenger image can be collected in real time, then the luggage is scanned by X-ray, a background binds the personnel information of the stage with the luggage X-ray image; when data are stored, X-ray visible images of luggage scanning are in one-to-one correspondence with passengers passing security check, and when a background analysis server identifies contraband goods, security check personnel can find passengers carrying the contraband goods or dangerous goods more quickly. On the basis of a traditional X-ray security check function, a person-bag automatic association function is added, and the luggage and the person to which the luggage belongs are bound through an image association technology, so that security check workers are helped to implement security check work more quickly and effectively. The address information of the data storage space and the luggage external image information are used as association intermediaries, and the data information between the passenger and the luggage is subjected to association storage, so that image tracing is facilitated.

Description

technical field [0001] The invention relates to the technical field of security inspection machines, in particular to an X-ray security inspection method and a security inspection device based on multi-camera fusion. Background technique [0002] Security inspection machines with X-ray as the core technology have long been popular in subways, airports, railway stations, large-scale event venues, logistics and other scenarios. However, behind the security, the existing security inspection system has pain points such as high labor cost, low efficiency, and single function. . In luggage security checks at stations, airports, docks, etc., it is common to encounter situations where similar luggage items are taken by mistake and the owner of the luggage cannot be found after the luggage security check is completed. In addition, when there are contraband items in the luggage, it is difficult to quickly , Accurately find the owner of the luggage item at the first time. Usually the...
