Description

Technical Field

[0001] The present invention belongs to the technical field of X-ray security inspection equipment, and particularly relates to an X-ray equipment control system based on intelligent security inspection. Background Art

[0002] The X-ray security inspection instrument, also known as the security inspection machine and the baggage security inspection instrument, is an electronic device that completes the inspection by means of a conveyor belt to send the baggage to be inspected into the X-ray inspection channel, and is mainly installed in places that require security inspection such as subways, airports, museums, and government agencies;

[0003] X-ray is an electromagnetic radiation with a wavelength shorter than that of visible light, and has a stronger penetration ability for solids and liquids than visible light, and can even penetrate a certain thickness of steel plate 1. When X-rays pass through an object, the internal structures of objects with different material compositions, different densities, and different thicknesses can absorb X-rays to varying degrees. The greater the density and thickness, the more rays are absorbed; the smaller the density and thickness, the less rays are absorbed. Therefore, the intensity of the rays transmitted from the object can reflect the internal structure information of the object 1. The X-ray security inspection instrument adopts a line scanning working mode, and the highly sensitive X-ray line array detector inside it scans the object layer by layer under the drive of the mechanical scanning device; after the transmitted ray signal is detected and processed, the obtained data is reconstructed into an image, and the internal information of the object can be presented on the image;

[0004] The traditional security inspection mode is to scan the object by means of two-dimensional planar imaging technology and display the obtained information in the form of a two-dimensional image. Security inspectors mainly rely on observing the two-dimensional object information presented on the display device screen to distinguish the nature and safety of the object. In this mode, security inspectors face a flat and lack of three-dimensional sense image, and it is difficult to clearly present the details and internal structures of the object in all directions. As the security inspection working hours increase, security inspectors need to highly concentrate their attention for a long time, carefully distinguish a large number of similar and complex two-dimensional images, and their minds are always in a highly tense state. In this way, not only is it extremely easy to cause visual fatigue, but also the sharpness of thinking will decline, resulting in a significant increase in the probability of missed inspections and misinspections during the long-term discrimination process by security inspectors. Summary of the Invention

[0005] The object of the present invention is to provide an X-ray equipment control system based on intelligent security inspection, aiming to solve the problem that in the prior art, when the above-mentioned X-ray equipment control system is in use, the traditional security inspection mode relies on two-dimensional plane imaging technology to scan articles and display the obtained information in the form of two-dimensional images. Security inspectors mainly rely on observing the two-dimensional article information presented on the display device screen to identify the nature and safety of articles. In this mode, security inspectors face flat and lack of three-dimensional images, and it is difficult to clearly present the details and internal structures of articles in all directions. As the duration of security inspection work increases, security inspectors need to highly concentrate their attention for a long time to carefully distinguish a large number of similar and complex two-dimensional images, and their minds are always in a highly tense state. In this way, not only is it extremely easy to cause visual fatigue, but also the sharpness of thinking will decrease, resulting in a significant increase in the probability of missed inspections and misinspections during the long-term discrimination process by security inspectors.

[0006] To achieve the above object, the present invention provides the following technical solution: An X-ray equipment control system based on intelligent security inspection includes an article detection module. After the article is placed on the conveyor belt of the X-ray equipment, the article detection module conducts detection. After the article detection module detects, it starts the X-ray source. After receiving the emitted X-ray, it is converted into an electrical signal, and the collected electrical signal is preliminarily processed.

[0007] The processed electrical signal data is transmitted to the image processing unit. The processed two-dimensional image is converted into a three-dimensional image for processing, and a VR device is used for three-dimensional observation to determine whether there are prohibited articles. If there are prohibited articles, the X-ray equipment and the VR device simultaneously emit an alarm signal to notify the case personnel for handling. If there are no prohibited articles, the article passes through the X-ray equipment normally, and the transmitted image of the article is stored and the data is recorded.

[0008] Preferably, as an X-ray equipment control system based on intelligent security inspection of the present invention, the three-dimensional image processing uses a multi-view plane scanning method to identify the surface features of the transmitted article. Specifically, it is obtained by performing plane scanning on the article from different angles and contains information on different sides of the object.

[0009] Preferably, as an X-ray equipment control system based on intelligent security inspection of the present invention, during the three-dimensional image processing, the image information obtained by scanning is transmitted to computer software, and a stereoscopic image generator in the computer is used to process and analyze the multi-view plane scanning images, and the plane images are fused to generate a stereoscopic image to simulate the three-dimensional space information of the object.

[0010] Preferably, in a control system for an X-ray device based on intelligent security inspection according to the present invention, the three-dimensional image obtained after three-dimensional image processing is connected to a VR device by wireless connection. The VR device will obtain the current viewing angle of the user, generate corresponding left-eye and right-eye images and display them to the security inspection personnel.

[0011] Preferably, in a control system for an X-ray device based on intelligent security inspection according to the present invention, the item detection module uses a light barrier sensor, and a semiconductor detector is used to receive X-rays.

[0012] Preferably, in a control system for an X-ray device based on intelligent security inspection according to the present invention, the electrical signal processing uses a signal acquisition device to perform preliminary processing on these electrical signals, specifically amplifying and filtering the electrical signals.

[0013] Preferably, in a control system for an X-ray device based on intelligent security inspection according to the present invention, the X-ray device and the VR device give out audible and visual alarms synchronously. In addition, the basis for judging whether it is a prohibited item lies in the rules and models of prohibited items preset inside the X-ray device.

[0014] Preferably, in a control system for an X-ray device based on intelligent security inspection according to the present invention, whether a prohibited item is detected in the processes of having prohibited items and having no prohibited items, the system will store the security inspection images and relevant data, and the relevant data mainly includes the detection time and the item type.

[0015] Preferably, in a control system for an X-ray device based on intelligent security inspection according to the present invention, multi-view plane scanning in the three-dimensional image processing process uses CT scanning to obtain CT data of the item, specifically including X-ray scanning information of different angles and levels of the item, and then generates a contour curve plane image of the item.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the present invention, the obtained X-ray data about the transported item is converted into two-dimensional image data, and then the obtained two-dimensional image data of the item is fused by a stereoscopic image generator in computer software for multi-view plane scanning images to generate a three-dimensional item contour image.

[0022] Please refer to Figure 1-2 , the present invention provides the following technical solutions: An X-ray equipment control system based on intelligent security inspection includes an item detection module. After the item is placed on the conveyor belt of the X-ray equipment, the item detection module conducts detection. After the item detection module detects, it starts the X-ray source. After receiving the emitted X-ray, it is converted into an electrical signal, and the collected electrical signal is preliminarily processed;

[0023] The processed electrical signal data is transmitted to the image processing unit. The processed two-dimensional image is converted into three-dimensional image processing, and a VR device is used for three-dimensional observation to determine whether there are prohibited items. If there are prohibited items, the X-ray equipment and the VR device simultaneously send out alarm signals to notify the case personnel for handling. If there are no prohibited items, the item passes through the X-ray equipment normally, and the transmitted image of the item is stored and the data is recorded.

[0024] Preferably: The three-dimensional image processing adopts a multi-view plane scanning method to identify the surface features of the transmitted item. Specifically, it is obtained by performing plane scanning on the item from different angles and contains information on different sides of the object.

[0025] Preferably: During the three-dimensional image processing, the image information obtained by scanning is transmitted to the computer software, and the stereoscopic image generator in the computer is used to process and analyze the multi-view plane scanning images, and the plane images are fused to generate a stereoscopic image to simulate the three-dimensional space information of the object.

[0026] Preferably: The stereoscopic image obtained after the three-dimensional image processing is connected to the VR device through a wireless connection method. The VR device will obtain the current viewing angle of the user, generate corresponding left-eye and right-eye images and display them to the security inspection personnel.

[0027] Preferably, the article detection module uses a light barrier sensor, and the semiconductor detector is used to receive X-rays.

[0028] Preferably, the signal acquisition device is used for the preliminary processing of these electrical signals in the electrical signal processing, specifically for amplifying and filtering the electrical signals.

[0029] Preferably, the X-ray device and the VR device give out audible and visual alarms synchronously. In addition, the basis for judging whether it is a prohibited item lies in the rules and models of prohibited items preset inside the X-ray device.

[0030] Preferably, whether prohibited items are detected in the process of having prohibited items and no prohibited items, the security inspection images and relevant data will be stored by the system. The relevant data mainly includes the detection time and the item type.

[0031] Preferably, in the multi-view plane scanning in the three-dimensional image processing, the CT data of the article is obtained by means of CT scanning, specifically including the X-ray scanning information of different angles and levels of the article, and then the contour curve plane image of the article is generated.

[0032] The specific working principle of the present invention: First, the personnel place the article on the conveyor belt on the surface of the X-ray device. After the light barrier sensor inside the X-ray device detects the article, the X-ray source is started to emit X-rays. The X-ray beam passes through the article to be inspected. After being absorbed by the article for a part, it bombards the semiconductor detector in the X-ray device channel. The semiconductor detector converts the X-rays into weak electrical signals, and then the electrical signals are processed. Then the processed electrical signals are output to the image processing unit. By converting the obtained X-ray data about the transported article into two-dimensional image data, and then the obtained two-dimensional image data of the article is fused with the images of the multi-view plane scanning through the stereoscopic image generator in the computer software to generate a three-dimensional contour image of the article. Then the security inspection personnel wear VR devices connected to the X-ray device, and display the three-dimensional article information in the field of vision of the security inspection personnel, which is convenient for presenting the details and internal structure of the article clearly in all directions. At the same time, it reduces the eye soreness of the security inspection personnel during long-term observation, improves the accuracy of the security inspection personnel in detecting the articles passing through the inspection. In addition, it is compared with the prohibited item model prefabricated inside the VR device used. If the prohibited item conditions are met, both the VR device and the X-ray device will give out audible and visual alarm sounds and notify the security inspection personnel to conduct on-site processing. If the violation conditions are not met, the article will pass normally on the X-ray device, and the image information and data record of the transported article will be stored for subsequent query and analysis.
