Description

Technical Field

[0001] This invention relates to the field of security inspection equipment technology, and in particular to a system and method for sharing CT security inspection equipment across multiple business scenarios. Background Technology

[0002] CT equipment is a non-invasive baggage inspection device that can produce two-dimensional X-ray images and three-dimensional perspective images of baggage through X-ray imaging. It can classify, identify and display the baggage based on characteristics such as density and atomic number. The interpreter can accurately determine the types of items contained in the baggage by looking at the two-dimensional and three-dimensional images generated after the CT equipment scans the baggage.

[0003] CT scanners can accurately identify dangerous and prohibited items such as drugs and explosives, and are gradually replacing traditional X-ray inspection equipment in airport security checks. They are already in use at several airports in China. Furthermore, due to their accurate substance classification and identification capabilities, CT scanners can accurately identify various dutiable goods and are widely used in customs inspections.

[0004] In civil aviation security applications, airport security departments need to conduct pre-boarding security checks on international departing passengers and their baggage, as well as domestic departing passengers and their baggage, including those from free trade zones. Customs also needs to conduct pre-boarding inspections. To avoid redundant equipment deployment and repeated baggage checks, it is necessary to simultaneously provide airport security and customs image interpreters with the two-dimensional X-ray images and three-dimensional perspective images generated after a single CT scan of passenger baggage for interpretation and analysis. However, there is currently no mature technology or model in China to provide the images of baggage after a single CT scan for simultaneous interpretation and analysis by airport security and customs. Therefore, there is an urgent need to develop a system and method for CT security inspection equipment that can be applied to multiple business scenarios. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a system and method for sharing CT security inspection equipment across multiple business scenarios, in order to solve the problem that in scenarios where passenger baggage or cargo needs to be inspected by CT equipment in multiple business scenarios, the existing CT security inspection system cannot provide the images of the baggage or cargo to be inspected after one inspection to multiple business scenarios for judgment and analysis at the same time, and the same item needs to be inspected repeatedly.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] On the one hand, the present invention provides a system for sharing CT security inspection equipment in multiple business scenarios, including: CT equipment, local image interpretation terminal, security inspection remote centralized image interpretation terminal, customs remote centralized image interpretation terminal, and server;

[0008] The local image interpretation terminal is connected to the CT equipment via a combination cable; the security check remote centralized image interpretation terminal and the customs remote centralized image interpretation terminal are respectively connected to the CT equipment via a network; the local image interpretation terminal, the security check remote centralized image interpretation terminal and the customs remote centralized image interpretation terminal are all used to display the X-ray images generated by the CT equipment after collecting baggage X-ray data and to receive the image interpretation results given by the operator;

[0009] The server is connected to the CT equipment, the security inspection centralized image interpretation terminal and the customs centralized image interpretation terminal via a network, and is used to store the image interpretation tasks, baggage image files and image interpretation results generated during system operation;

[0010] The number of CT devices is n1, where n1 ≥ 1 and is an integer;

[0011] The number of local image analysis terminals is n1, where n1 ≥ 1 and is an integer;

[0012] The number of remote centralized image interpretation terminals for security checks is n2, where n2 ≥ 0 and is an integer;

[0013] The number of customs remote centralized image interpretation terminals is n3, where n3 ≥ 1 and is an integer.

[0014] The number of servers is n4, where n4 ≥ 1 and is an integer;

[0015] The scenarios include airport baggage check-in security screening, passenger carry-on baggage security screening, and cargo security screening.

[0016] On the other hand, the present invention also provides a method for sharing CT security inspection equipment across multiple business scenarios, which includes the following steps using the above system:

[0017] Step 1: System Operation Settings: Set the system operation mode according to the application scenario; set the conditions for whether the CT equipment in the system will send the acquired item images to the customs centralized image interpretation terminal;

[0018] Step 2: Start the system. The CT equipment determines whether to send the inspection images of the items to the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal according to the system operation mode. If necessary, an initial image interpretation task is generated and written to the server. The initial image interpretation task is continuously updated to the final image interpretation task.

[0019] Step 3: Based on the judgment results in Step 2, the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal obtain the initial image interpretation task and the final image interpretation task through the server, connect to the corresponding CT device according to the initial image interpretation task information, and the CT device sends the baggage image data packet to the corresponding image interpretation terminal. The image interpretation terminal displays the complete three-dimensional and two-dimensional radiographic images of the baggage according to the received baggage image data packet.

[0020] Step 4: Based on the 3D and 2D X-ray images of the luggage displayed on the image interpretation terminal, the operator makes a judgment on the images, and the image interpretation terminal provides the judgment result. The image interpretation terminal then sends the judgment result to the corresponding CT device.

[0021] Step 5: The image processing terminal writes the luggage image file and the image processing results to the server.

[0022] Furthermore, the system operating modes include:

[0023] In airport baggage security inspection scenarios, customs does not need to supervise, and the system operates in a remote centralized image analysis mode.

[0024] In the airport baggage security inspection scenario, customs needs to supervise, and the system operation mode is remote centralized image interpretation for security inspection and remote centralized image interpretation for customs.

[0025] In the scenario of security inspection of passengers' hand luggage, customs does not need to supervise, and the system operates in the mode of local security inspection image interpretation.

[0026] In the scenario of security inspection of passengers' hand luggage, customs needs to supervise, and the system operation mode is local security inspection image interpretation and remote centralized customs image interpretation.

[0027] In cargo security inspection scenarios, customs does not require supervision, and the system operates in a remote centralized image interpretation mode for security inspection.

[0028] In cargo security inspection scenarios, customs needs to supervise, and the system operates in two modes: remote centralized image interpretation for security inspection and remote centralized image interpretation for customs.

[0029] Furthermore, in step 1, the conditions for setting whether the CT equipment in the system sends the acquired images of the items to the customs centralized image interpretation terminal include: setting or configuring all images of all baggage inspected by a certain CT equipment to be sent to the customs centralized image interpretation terminal based on the attributes of the baggage to be inspected; the attributes of the baggage to be inspected include the flight, destination, origin of the passenger to whom the baggage belongs, and the time period of baggage inspection.

[0030] Further, step 2 includes:

[0031] The system starts running, and the CT equipment and the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal automatically connect to the server through network communication;

[0032] When a CT scanner inspects baggage, the baggage enters the scanner's channel and blocks the light barrier at the scanner's entrance, generating a corresponding bag ID. Based on the system's operating mode and the settings for sending the acquired images to the customs' centralized image processing terminal, the system determines whether to send the baggage images to the security check remote centralized image processing terminal and / or the customs' remote centralized image processing terminal. If so, the initial image processing task for the baggage images acquired in this instance is automatically stored on the server.

[0033] Based on the system's operating mode and the set conditions for sending acquired item images to the customs centralized image interpretation terminal, the system determines whether to send baggage images to the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal. If yes, it waits for the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal to connect and request data. Simultaneously, as baggage continues to pass through the CT equipment channel, the CT equipment continues to complete the acquisition and reconstruction of baggage image data and sequentially generates slice image data, continuously updating the reconstructed data to the data packet of the same image. If no, it simply follows the normal local acquisition and display process, displaying complete 3D and 2D X-ray images of the baggage on the local CT equipment operating terminal.

[0034] After the reconstruction of the luggage and items image data is completed, the system automatically recognizes and intelligently interprets the two-dimensional ray images and three-dimensional perspective images of the items.

[0035] During the reconstruction of luggage images, the CT equipment continuously updates the initial image interpretation task for the corresponding luggage images and stores it on the server to obtain the final image interpretation task.

[0036] Furthermore, the initial image interpretation task includes information such as the CT device network IP address (CTIP), network communication port number (PortNo), and package number (BagID).

[0037] Furthermore, the final image interpretation task includes: CT device network IP address (CTIP), network communication port number (PortNo), package number (BagID), whether TIP is enabled (TIPTag), number of slice images, slice image generation time, slice image number, and information on automatic recognition and intelligent image interpretation results.

[0038] Further, step 3 includes:

[0039] The security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal receive the initial image interpretation task from the server, and initiate a network connection request to the corresponding CT device based on the network IP address of the CT device corresponding to the initial image interpretation task. After receiving the connection request, the CT device establishes a network connection with the corresponding centralized image interpretation terminal.

[0040] After the CT equipment establishes a transmission connection for the current image data with the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal, the CT equipment sends all the baggage image data packets that have been reconstructed to the corresponding centralized image interpretation terminal until the CT equipment determines through the packet splitting algorithm that the current slice image is the last slice image of the baggage being inspected, and sets the flag variable of the last slice image in the last slice image and sends it to the corresponding centralized image interpretation terminal together.

[0041] The security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal display complete three-dimensional and two-dimensional ray images of the baggage based on the received baggage image data packets;

[0042] The CT equipment simultaneously acquires and reconstructs subsequent baggage images while awaiting the results of this baggage image analysis.

[0043] Further, step 4 includes:

[0044] Security personnel interpret the three-dimensional and two-dimensional X-ray images of luggage using the local image interpretation terminal of the CT equipment, operate the local image interpretation terminal to generate the interpretation results, and write the results into the CT equipment;

[0045] Security personnel interpret the three-dimensional and two-dimensional X-ray images of luggage using the remote centralized image interpretation terminal, operate the terminal to generate interpretation results, and then send the interpretation results to the corresponding CT equipment.

[0046] Customs officers interpret the three-dimensional and two-dimensional radiographic images of luggage using the customs remote centralized image interpretation terminal. The terminal then sends the interpretation results to the corresponding CT equipment.

[0047] Further, step 5 includes: the local image interpretation terminal of the CT equipment stores the baggage image file and the interpretation result obtained by the local image interpretation terminal to the server; if the security check centralized image interpretation terminal participates in the interpretation, the security check centralized image interpretation terminal stores the baggage image file and the security check centralized image interpretation result to the server; if the customs centralized image interpretation terminal participates in the interpretation, the customs centralized image interpretation terminal stores the baggage image file and the customs centralized image interpretation result to the server.

[0048] The luggage image file includes luggage image data packets, automatic recognition, and intelligent image analysis results data.

[0049] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0050] 1. The system and method for sharing CT security inspection equipment in multiple business scenarios of the present invention can provide images of luggage or goods to be inspected after one inspection to multiple business scenarios for judgment and analysis at the same time, avoiding the repeated inspection of the same item.

[0051] 2. In practical applications, by deploying the CT equipment for on-site image acquisition separately from the image interpretation terminal, the work efficiency of image interpretation personnel is improved, the possibility of direct contact between image interpretation personnel and passengers, luggage, or goods is reduced, and the risk of corruption is decreased. At the same time, the system and method of this invention can also reduce redundant resource investment and save costs.

[0052] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0053] The accompanying drawings are for illustrative purposes only and are not intended to limit the invention. Throughout the drawings, the same reference numerals denote the same parts.

[0054] Figure 1 This invention relates to a system for sharing CT security inspection equipment across multiple business scenarios;

[0055] Figure 2 This is a flowchart of the method for sharing CT security inspection equipment across multiple business scenarios according to the present invention. Detailed Implementation

[0056] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0057] This invention provides a system for sharing CT security inspection equipment across multiple business scenarios, applicable to airport baggage security inspection, passenger carry-on baggage security inspection, and cargo security inspection scenarios, including: CT equipment, local image interpretation terminal, remote centralized image interpretation terminal for security inspection, remote centralized image interpretation terminal for customs, and server;

[0058] The local image interpretation terminal is connected to the CT equipment via a combination cable. The security check remote centralized image interpretation terminal and the customs remote centralized image interpretation terminal are connected to the CT equipment via a network and can be connected to the same network system. All three terminals—local, security check, and customs—are used to display the X-ray images generated by the CT equipment after acquiring X-ray data from luggage and to receive interpretation results from the operators.

[0059] The server is connected to the CT equipment, the security inspection centralized image interpretation terminal and the customs centralized image interpretation terminal via a network, forming a system that shares CT security inspection equipment. It is used to store the image interpretation tasks, baggage image files and image interpretation results generated during the system operation.

[0060] The number of CT scanners is n1, where n1 ≥ 1 and is an integer; the number of local image interpretation terminals is n1, where n1 ≥ 1 and is an integer; the number of remote centralized image interpretation terminals for security checks is n2, where n2 ≥ 0 and is an integer; the number of remote centralized image interpretation terminals for customs is n3, where n3 ≥ 1 and is an integer; and the number of servers is n4, where n4 ≥ 1 and is an integer.

[0061] It should be noted that the number of CT scanners is the same as the number of local image interpretation terminals, with one CT scanner corresponding to one local image interpretation terminal. One CT scanner can correspond to one or more remote centralized image interpretation terminals for security checks, customs remote centralized image interpretation terminals, and servers. Therefore, the number of CT scanners, remote centralized image interpretation terminals for security checks, and customs remote centralized image interpretation terminals and servers can be the same or different, generally configured flexibly according to actual business needs. The number of remote centralized image interpretation terminals for security checks may be zero, because in the scenario of passenger carry-on baggage security checks, the security system uses local image interpretation terminals for image interpretation, so there is no need to set up remote centralized image interpretation terminals.

[0062] Specifically, in airport baggage security screening scenarios, CT scanners are deployed at passenger check-in islands or counters in the departure hall. Airport security and customs both analyze passenger baggage images through centralized image interpretation. Remote centralized image interpretation terminals for security and customs are deployed in their respective rooms. Baggage signals indicating "open for inspection" (either security or customs) are sent to the baggage sorting system, which then sorts the baggage to designated inspection points. The relationship between the remote centralized image interpretation terminals for security and customs and the CT scanners is not one-to-one, but rather many-to-many.

[0063] In the scenario of passenger carry-on baggage security inspection, CT equipment is deployed in the airport passenger security check channel, and airport security inspectors use the local image interpretation terminal of the CT equipment to interpret the images; the customs remote centralized image interpretation terminal is deployed in the customs centralized image interpretation room, and customs inspectors use the images in the centralized image interpretation room. The local image interpretation terminal of the security check and the CT security check equipment have a one-to-one relationship, while the customs remote centralized image interpretation terminal and the CT security check equipment have a many-to-many relationship.

[0064] In cargo security inspection scenarios, CT scanners are deployed on express mail or cargo inspection lines. Airport security and customs use centralized image analysis to interpret and analyze images of passengers' checked baggage. The relationship between the centralized image analysis terminals of security and customs and the CT security inspection equipment is not one-to-one, but rather many-to-many.

[0065] This invention also provides a method for sharing CT security inspection equipment across multiple service scenarios, implemented through the aforementioned CT security inspection equipment system, comprising the following steps:

[0066] Step 1: System Operation Settings: Set the system operation mode according to the system application scenario; set the conditions for whether the CT equipment in the system will send the acquired item images to the customs centralized image interpretation terminal;

[0067] Step 2: Start the system. The CT equipment determines whether to send the inspection images of the items to the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal according to the system operation mode. If necessary, an initial image interpretation task is generated and written to the server. The initial image interpretation task is continuously updated to the final image interpretation task.

[0068] Step 3: Based on the judgment results in Step 2, the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal obtain the initial image interpretation task and the final image interpretation task through the server, connect to the corresponding CT device according to the initial image interpretation task information, and the CT device sends the baggage image data packet to the corresponding image interpretation terminal. The image interpretation terminal displays the complete three-dimensional and two-dimensional radiographic images of the baggage according to the received baggage image data packet.

[0069] Step 4: Based on the 3D and 2D X-ray images of the luggage displayed on the image interpretation terminal, the operator makes a judgment on the images, and the image interpretation terminal provides the judgment result. The image interpretation terminal then sends the judgment result to the corresponding CT device.

[0070] Step 5: The image processing terminal writes the luggage image file and the image processing results to the server.

[0071] Specifically, in step 1, setting the system operating mode according to the system application scenario includes:

[0072] In airport baggage security inspection scenarios, customs does not need to supervise, and the system operates in a remote centralized image analysis mode.

[0073] In the airport baggage security inspection scenario, customs needs to supervise, and the system operation mode is remote centralized image interpretation for security inspection and remote centralized image interpretation for customs.

[0074] In the scenario of security inspection of passengers' hand luggage, customs does not need to supervise, and the system operates in the mode of local security inspection image interpretation.

[0075] In the scenario of security inspection of passengers' hand luggage, customs needs to supervise, and the system operation mode is local security inspection image interpretation and remote centralized customs image interpretation.

[0076] In cargo security inspection scenarios, customs does not require supervision, and the system operates in a remote centralized image interpretation mode for security inspection.

[0077] In cargo security inspection scenarios, customs needs to supervise, and the system operates in two modes: remote centralized image interpretation for security inspection and remote centralized image interpretation for customs.

[0078] It should be noted that after the system operation mode is set according to the system application scenario, the system's security inspection image judgment method (local terminal image judgment and security inspection remote centralized terminal image judgment) is determined accordingly. Once the image judgment method is determined, it cannot be changed during the entire operation of the system. If it needs to be changed, the system needs to be restarted to set it.

[0079] Specifically, in step 1, the conditions for whether the CT equipment in the system sends the acquired images of the items to the customs centralized image analysis terminal are set. These conditions can be set according to the attributes of each piece of baggage being inspected, such as the flight, destination, passenger's place of origin, and inspection time period. Alternatively, it can be set that all images of all baggage inspected by a certain CT equipment are sent to the customs centralized image analysis terminal. The specific setting conditions are determined according to actual application needs. Preferably, the flight of the baggage is set as the condition for whether the CT equipment sends the acquired images of the items to the customs centralized image analysis terminal. If the flight of the baggage to be inspected is consistent with the flight information set in the system, the CT equipment will send the acquired images of the items to the customs centralized image analysis terminal. If the flight of the baggage to be inspected is inconsistent with the flight information set in the system, the CT equipment will not send the acquired images of the items to the customs centralized image analysis terminal.

[0080] Specifically, in step 2, after completing the system operation settings, the system is started. The CT equipment, based on the system operation mode, determines whether to send the inspection images of baggage to the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal. If so, an initial image interpretation task is generated and written to the server. The initial image interpretation task is continuously updated to the final image interpretation task, specifically including:

[0081] The system starts running, and the CT equipment and the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal automatically connect to the server through network communication;

[0082] When a CT scanner inspects luggage, the luggage enters the scanner's channel and obstructs the light barrier at the scanner's entrance, generating a corresponding bag ID. Based on the system's operating mode and the set conditions for sending the acquired image to the customs' centralized image processing terminal, the system determines whether to send the luggage image to the security check remote centralized image processing terminal and / or the customs' remote centralized image processing terminal. If so, the system automatically stores the initial image processing task of the acquired luggage image to the server. The initial image processing task includes the CT scanner's network IP address (CTIP), network communication port number (PortNo), and bag ID.

[0083] Based on the system's operating mode and the set conditions for sending acquired item images to the customs centralized image interpretation terminal, the system determines whether to send baggage images to the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal. If yes, it waits for the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal to connect and request data. Simultaneously, as baggage continues to pass through the CT equipment channel, the CT equipment continues to complete the acquisition and reconstruction of baggage image data and sequentially generates slice image data, continuously updating the reconstructed data to the data packet of the same image. If no, it simply follows the normal local acquisition and display process, displaying complete 3D and 2D X-ray images of the baggage on the local CT equipment operating terminal.

[0084] After the reconstruction of the luggage and items image data is completed, the system automatically recognizes and intelligently interprets the two-dimensional ray images and three-dimensional perspective images of the items.

[0085] During the reconstruction of baggage images, the CT equipment continuously updates the initial image judgment task for the corresponding baggage images and stores it on the server to obtain the final image judgment task. The final image judgment task includes: the CT equipment network IP address (CTIP), network communication port number (PortNo), package number (BagID), whether TIP is enabled (TIPTag), number of slice images, slice image generation time, slice image number, and information on automatic recognition and intelligent image judgment results.

[0086] It should be noted that automatic identification and intelligent image analysis are two functions integrated into the internal program of the CT equipment. Automatic identification obtains the atomic number and density of substances inside the luggage based on the acquired luggage image data, and automatically identifies information such as drugs and explosives. Intelligent image analysis is a machine learning method based on deep neural networks. Based on the annotation and learning of a large number of image samples, the intelligent image analysis algorithm can be called to identify whether the luggage contains dangerous goods, prohibited items, taxable goods, etc., based on the reconstructed image data.

[0087] It should be noted that the information included in the initial image judgment information and the final image judgment task is not baggage image data, but rather a description of the data characteristics of the CT device network IP address (CTIP), network communication port number (PortNo), package number (BagID), package start inspection time (InspectTime), whether TIP is enabled (TIPTag), number of slice images, slice image generation time, slice image number, automatic recognition, and intelligent image judgment results. The method of the present invention first assigns the initial image judgment task information to the security inspection remote centralized image judgment terminal and / or the customs remote centralized image judgment terminal. Then, the image judgment terminal connects to the corresponding CT device according to the initial image judgment task information, and the CT device sends the baggage image data packet to the corresponding image judgment terminal.

[0088] Specifically, based on the judgment result in step 2, the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal obtain the initial image interpretation task and the final image interpretation task through the server. According to the initial image interpretation task, they connect to the corresponding CT equipment. The CT equipment sends the baggage image data packet to the corresponding image interpretation terminal. The image interpretation terminal displays complete three-dimensional and two-dimensional radiographic images of the baggage based on the received baggage image data packet, including:

[0089] The security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal receive the initial image interpretation task from the server, and initiate a network connection request to the corresponding CT device based on the network IP address of the CT device corresponding to the initial image interpretation task. After receiving the connection request, the CT device establishes a network connection with the corresponding centralized image interpretation terminal.

[0090] After the CT scanner establishes a transmission connection with the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal, the CT scanner sends all the baggage image data packets that have been reconstructed to the corresponding centralized image interpretation terminal. This continues until the CT scanner determines, through a packet splitting algorithm, that the current slice image is the last slice image of the baggage to be inspected. The CT scanner then sets a flag variable for the last slice image and sends it to the corresponding centralized image interpretation terminal. By setting the flag variable and sending it to the corresponding centralized image interpretation terminal, the centralized image interpretation terminal can know that the CT scanner has completed the acquisition and reconstruction of the baggage for this image interpretation task.

[0091] The security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal display complete three-dimensional and two-dimensional ray images of the baggage based on the received baggage image data packets;

[0092] The CT equipment simultaneously acquires and reconstructs subsequent baggage images while awaiting the results of this baggage image analysis.

[0093] Specifically, in step 4, based on the 3D and 2D X-ray images of the luggage displayed on the image interpretation terminal, the operator interprets the images, the image interpretation terminal provides the interpretation result, and the image interpretation terminal sends the interpretation result to the corresponding CT equipment, including:

[0094] Security personnel interpret the three-dimensional and two-dimensional X-ray images of luggage using the local image interpretation terminal of the CT equipment, operate the local image interpretation terminal to generate the interpretation results, and write the results into the CT equipment;

[0095] Security personnel interpret the three-dimensional and two-dimensional X-ray images of luggage using the remote centralized image interpretation terminal, operate the terminal to generate interpretation results, and then send the interpretation results to the corresponding CT equipment.

[0096] Customs officers interpret the three-dimensional and two-dimensional radiographic images of luggage using the customs remote centralized image interpretation terminal. The terminal then sends the interpretation results to the corresponding CT equipment.

[0097] It should be noted that the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal are connected to the CT equipment via network communication to send the image interpretation results to the corresponding CT equipment.

[0098] Specifically, in step 5, the image processing terminal writes the luggage image file and the image processing result to the server, including:

[0099] The CT equipment's local image interpretation terminal stores the baggage image file and the interpretation results obtained by the local image interpretation terminal to the server; if the security check centralized image interpretation terminal participates in the interpretation, then the security check centralized image interpretation terminal stores the baggage image file and the security check centralized image interpretation results to the server; if the customs centralized image interpretation terminal participates in the interpretation, then the customs centralized image interpretation terminal stores the baggage image file and the customs centralized image interpretation results to the server.

[0100] The luggage image file includes luggage image data packets, automatic recognition, and intelligent image analysis results data.

[0101] For subsequent checks of luggage and items, repeat steps 1 through 3.

The final image interpretation task includes: the CT device's network IP address, network communication port number, package number, whether TIP is enabled, number of slice images, slice image generation time, slice image number, and information on automatic recognition and intelligent image interpretation results.

2. The method according to claim 1, characterized in that, In step 1, the conditions for setting whether the CT equipment in the system sends the acquired images of the items to the customs centralized image interpretation terminal include: setting or setting all images of all baggage inspected by a certain CT equipment to be sent to the customs centralized image interpretation terminal according to the baggage attributes to be inspected; the baggage attributes to be inspected include the flight, destination, origin of the passenger to whom the baggage belongs, and baggage inspection time period.

3. The method according to claim 1, characterized in that, Step 2 further includes: the system starts running, and the CT equipment and the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal automatically connect to the server through network communication; When a CT scanner inspects luggage, the luggage enters the scanner's channel and blocks the light barrier at the scanner's entrance. This generates a corresponding package number for the luggage. Based on the system's operating mode and the settings for sending the acquired images to the customs' centralized image processing terminal, the system determines whether to send the luggage images to the security check remote centralized image processing terminal and / or the customs' remote centralized image processing terminal. If so, the system automatically stores the initial image processing task of the collected luggage images to the server. Based on the system's operating mode and the set conditions for sending acquired item images to the customs centralized image interpretation terminal, the system determines whether to send baggage images to the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal. If yes, it waits for the security check remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal to connect and request data. Simultaneously, as baggage continues to pass through the CT equipment channel, the CT equipment continues to complete the acquisition and reconstruction of baggage image data and sequentially generates slice image data, continuously updating the reconstructed data to the data packet of the same image. If no, it simply follows the normal local acquisition and display process, displaying complete 3D and 2D X-ray images of the baggage on the local CT equipment operating terminal. After the reconstruction of the luggage and item image data is completed, the system automatically identifies and intelligently interprets the two-dimensional ray images and three-dimensional perspective images of the items.

4. The method according to claim 1, characterized in that, Step 3 includes: The security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal receive the initial image interpretation task from the server, and initiate a network connection request to the corresponding CT device based on the network IP address of the CT device corresponding to the initial image interpretation task. After receiving the connection request, the CT device establishes a network connection with the corresponding centralized image interpretation terminal. After the CT equipment establishes a transmission connection for the current image data with the security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal, the CT equipment sends all the baggage image data packets that have been reconstructed to the corresponding centralized image interpretation terminal until the CT equipment determines through the packet splitting algorithm that the current slice image is the last slice image of the baggage being inspected, and sets the flag variable of the last slice image in the last slice image and sends it to the corresponding centralized image interpretation terminal together. The security inspection remote centralized image interpretation terminal and / or the customs remote centralized image interpretation terminal display complete three-dimensional and two-dimensional ray images of the baggage based on the received baggage image data packets; The CT equipment simultaneously acquires and reconstructs subsequent baggage images while awaiting the results of this baggage image analysis.

5. The method according to claim 1, characterized in that, Step 4 includes: Security personnel interpret the three-dimensional and two-dimensional X-ray images of luggage using the local image interpretation terminal of the CT equipment, operate the local image interpretation terminal to generate the interpretation results, and write the results into the CT equipment; Security personnel interpret the three-dimensional and two-dimensional X-ray images of luggage using the remote centralized image interpretation terminal, operate the terminal to generate interpretation results, and then send the interpretation results to the corresponding CT equipment. Customs officers interpret the three-dimensional and two-dimensional radiographic images of luggage using the customs remote centralized image interpretation terminal. The terminal then sends the interpretation results to the corresponding CT equipment.

6. The method according to claim 1, characterized in that, Step 5 includes: the CT equipment local image interpretation terminal storing the baggage image file and the interpretation results obtained by the local image interpretation terminal to the server; if the security check centralized image interpretation terminal participates in the interpretation, the security check centralized image interpretation terminal stores the baggage image file and the security check centralized image interpretation results to the server; if the customs centralized image interpretation terminal participates in the interpretation, the customs centralized image interpretation terminal stores the baggage image file and the customs centralized image interpretation results to the server. The luggage image file includes luggage image data packets, automatic recognition, and intelligent image analysis results data.
