Problems solved by technology

[0002] Existing cross-border items mainly include logistics packages such as international express delivery. Since it is not convenient to unpack and inspect the packages, the inspection method mainly adopts the traditional X-ray image detection of contraband. Detect whether it contains contraband in light pictures, such as knives and guns, and can locate contraband under complex occlusion and interference conditions, providing clues for manual unpacking inspection
[0003] The current detection of contraband in X-ray pictures is mainly based on manual inspection. Relevant staff need to monitor the screen at all times and give manual judgment results in a short period of time, and two-dimensional X-ray pictures can only show the details of the inspected items. 2D outline, easy to miss
[0004] At the same time, although X-ray imaging technology can realize the density discrimination of different items in common luggage, and has a significant screening effect on the hidden drugs in the interlayer of luggage, it cannot identify the element types of the items; in addition, the density of many explosives is close to that of common daily necessities. Therefore, detecting explosives only from the density will often cause missed detection and false alarms
Not only can it completely fail to meet the high-speed and large-scale needs of cross-border goods logistics security inspection, but also if manual inspection misses contraband, it may cause serious consequences

Embodiment 1

[0044] figure 1 It shows a step diagram of a cross-border article inspection method according to the present invention.

[0045] Such as figure 1 As shown, a cross-border article inspection method according to the present invention includes:

[0046] Scanning at least one cross-border item in the package on the conveyor belt with a CT detection device, generating multiple cross-sectional images of each cross-border item and obtaining the density and atomic number of each cross-border item;

[0047] Generate 3D images of cross-border items based on multiple cross-sectional images and densities of each cross-border item;

[0048] Based on the three-dimensional image, density and atomic number of cross-border items to determine whether the cross-border items are controlled items, suspected drugs or suspected explosives;

[0049] If it is judged that the cross-border goods are suspected drugs or suspected explosives, mark the cross-border goods;

[0050] Use neutron detection ...

Embodiment 2

[0071] Such as figure 2 As shown, the embodiment of the present invention also proposes a cross-border article image inspection system, including:

[0072] CT detection device 1, neutron detection device 2 and security inspection main control display unit 3, CT detection device 1 and neutron detection device 2 are arranged in sequence along the conveying direction of conveyor belt 4, CT detection device 1 and neutron detection device 2 are respectively connected to the security inspection The main control display unit 3 is connected through communication;

[0073] The CT detection device 1 is used to scan at least one cross-border item in the package 5 on the conveyor belt 4, generate multiple cross-sectional images of each cross-border item and obtain the density and atomic number of each cross-border item;

[0074] The neutron detection device 2 is used to detect the ratio and content of toxic and explosive-related elements of marked cross-border articles in the package 5;...

Abstract

The invention discloses a cross-border article inspection method and system, and the method comprises the steps: scanning at least one cross-border article located in a package on a conveyor belt through a CT detection device, generating a plurality of section images of each cross-border article, and obtaining the density and atomic number of each cross-border article; generating a three-dimensional image of each cross-border article according to the plurality of section images and the density of each cross-border article; judging whether the cross-border article belongs to a controlled article, a suspected drug or a suspected explosive based on the three-dimensional image, the density and the atomic number of the cross-border article; if the cross-border article is judged to be a suspected drug or a suspected explosive, marking the cross-border article; detecting the ratio and content of toxic explosive related elements of the marked cross-border article in the package through a neutron detection device; and judging whether the cross-border article is a drug or an explosive according to the ratio and the content of the related elements of the toxic explosive. The accuracy of drugand explosive inspection is improved, the risk of manual inspection is reduced, and the inspection efficiency of cross-border articles is improved.
