Description

TECHNICAL FIELD

[0001] The present application relates to the field of security inspection technology, in particular to a smart detection system and method with delayed prompting. BACKGROUND

[0002] Today, artificial intelligence technology is widely used, and the application of artificial intelligence technology in the field of airport security inspection is also rapidly following up. Among them, the smart detection system used to assist the security inspector in judgment has begun to be applied in airports.

[0003] In the security inspection site with the smart detection system, the security inspection process is as follows: the image of the luggage is displayed on the security inspector's judgment screen, the security inspector actively observes the image for possible contraband, the smart detection system analyzes the image of the luggage and gives a detection result, the security inspector observes the area where the detection frame (a square closed frame generated by the smart detection system to identify the position of the contraband on the image) is located, finds the existing contraband, and the security inspector identifies the position of the contraband on the image by drawing an open detection frame (clicking the center point near the location of the contraband with the mouse to form a square closed frame of a fixed size centered on the mouse click point displayed on the screen). According to the identification of the security inspector for the contraband, the security inspector gives an open detection or release judgment result for the image of the luggage.

[0004] Any technology has a process of gradual development and improvement, and artificial intelligence technology is no exception. The smart detection system applied in the security inspection site is still in the process of gradual improvement. When detecting the actual existing contraband, there is a certain degree of false positives or false negatives. At present, the existing smart detection system immediately prompts the security inspector to identify the area of the contraband by using a square frame to mark the four sides of the contraband on the security inspector's judgment screen after discovering the contraband. This immediate prompting method has a positive auxiliary effect on the security inspector's judgment, but the immediate prompting method has a serious problem. Some security inspectors mistakenly believe that the current smart detection system can completely replace human judgment of contraband, which makes some security inspectors abandon the consciousness of active judgment and completely rely on the smart detection system. In the case that the smart detection system is still in the process of gradual improvement, this dependence behavior not only causes the degradation of the security inspector's business level, but also may cause the missed detection of contraband, thereby forming a security risk and posing a great threat to the personal and property safety of passengers. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application aims to provide a smart detection system and method with delayed prompting, which changes the immediate prompting method of the detection frame to a delayed prompting method, so that the security inspection system has the ability to discover the case where the security inspector relies on the detection frame for judgment, thereby avoiding the occurrence of security risks.

[0006] In order to achieve the above object, the present application adopts the following technical solutions:

[0007] The intelligent detection system with delay prompt comprises an X-ray machine, an intelligent detection server, a data server and a management workstation.

[0008] Further, the X-ray machine is used for scanning the to-be-detected article and generating an image, and delaying the display of the detection frame; the intelligent detection server is used for analyzing the image and generating a detection frame and returning it to the X-ray machine when contraband is detected; the data server is used for storing the image, the interpretation result, the opening detection frame and the detection frame; and the management workstation is used for analyzing the image, the interpretation result, the opening detection frame and the detection frame.

[0009] Further, the X-ray machine adopts a CMEX device.

[0010] Further, the intelligent detection server adopts a FISCAN contraband intelligent detection system.

[0011] The present application also provides a method using the above intelligent detection system, and the specific process is as follows:

[0012] S1, using the X-ray machine to perform X-ray scanning on the to-be-detected article and generating an image; the intelligent detection server detects the image generated by the X-ray machine, generates a detection frame when contraband is detected, and returns the information of the detection frame to the X-ray machine;

[0013] S2, when the X-ray machine receives the information of the detection frame, the detection frame is set to a hidden state and is not immediately displayed on the screener interpretation screen;

[0014] S3, when the set condition is met, the X-ray machine modifies the state of the detection frame from hidden to displayed, and the detection frame is displayed on the screener interpretation screen;

[0015] S4, the X-ray machine stores the image, the interpretation result, the opening detection frame and the detection frame to the data server, and the management workstation obtains the image, the interpretation result, the opening detection frame and the detection frame from the data server, analyzes the image, the interpretation result, the opening detection frame and the detection frame, judges whether there is a situation that the screener relies on the detection frame for interpretation, and whether there is a situation that the screener and the intelligent detection system miss detection; the opening detection frame is manually drawn by the screener and is used for identifying the position of the contraband on the image.

[0016] Further, the set condition is any one of the following conditions:

[0017] (1) the time counting starts from the detection frame being returned to the X-ray machine and being set to the hidden state, and the counting time reaches the set value;

[0018] (2) The position of the hidden probe box in the image is about to move off the screen;

[0019] (3) When the X-ray machine’s conveyor belt starts running from a stopped state, the current security inspector sees a hidden detection box in the image on the screen.

[0020] (4) The current interpretation result is open for inspection, released, or timed out. The security inspector interprets that there is a hidden detection box in the image on the screen.

[0021] The beneficial effects of this invention are as follows: This invention changes the existing immediate notification method of the detection frame, allowing it to provide a delayed notification after certain conditions are met. This solves the problem of security personnel relying on the detection frame for interpretation, dispelling the concerns of airport management regarding the use of intelligent detection systems and removing obstacles to their widespread adoption. Simultaneously, through the analysis of images, interpretation results, open inspection frames, and detection frames, this invention can also identify prohibited items missed by security personnel and by the intelligent detection system. Based on this, it can effectively improve the professional skills of security personnel and enhance the prohibited item identification capabilities of the intelligent detection system.

It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0025] Example 1

[0026] This embodiment provides an intelligent detection system with delayed alerts, such as... Figure 1 As shown, it includes an X-ray machine 21, an intelligent detection server 22, a data server 23, and a management workstation 24; the X-ray machine 21 is connected to the intelligent detection server 22 and the data server 23 respectively, and the data server 23 is connected to the management workstation 24.

[0027] The X-ray machine 21 is used to scan the object to be detected and generate an image, and to display the detection frame in a delayed manner. The intelligent detection server 22 is used to analyze the image and generate a detection frame when contraband is detected, and then return the information of the detection frame (including the position information of the detection frame in the image) to the X-ray machine 21. The data server 23 is used to store the image, the interpretation result, the opening detection frame, and the detection frame. The management workstation 24 is used to analyze the image, the interpretation result, the opening detection frame, and the detection frame. The opening detection frame is drawn manually by the security officer and is used to identify the position of the contraband on the image

[0028] In the embodiment, the X-ray machine adopts a CMEX device, and the intelligent detection server adopts a FISCAN contraband intelligent detection system.

[0029] Embodiment 2

[0030] The embodiment provides a method for using the intelligent detection system in Embodiment 1, as shown in the figure, and the specific process is as follows: Figure 2

[0031] S1, using the X-ray machine 21 to perform X-ray scanning on the object to be detected and generate an image; the intelligent detection server 22 detects the image generated by the X-ray machine 21, generates a detection frame when contraband is detected, and returns the information of the detection frame to the X-ray machine 21.

[0032] S2, when the X-ray machine 21 receives the detection frame, the detection frame is set to a hidden state and is not immediately displayed on the security officer's interpretation screen.

[0033] S3, when any of the following conditions is met, the X-ray machine 21 modifies the state of the detection frame from hidden to displayed, and the detection frame is displayed on the security officer's interpretation screen:

[0034] (1) The time counting from when the detection frame is returned to the X-ray machine and set to the hidden state reaches a set value.

[0035] (2) The position of the detection frame is about to move out of the screen. Since the image will enter the security officer's interpretation screen from one side of the screen and move out of the screen from the other side of the screen, if the security officer still does not find the contraband when the position of the detection frame is about to move out of the screen, the X-ray machine 21 modifies the state of the detection frame from hidden to displayed, and the detection frame is displayed on the security officer's interpretation screen.

[0036] (3) When the conveying belt of the X-ray machine 21 starts to run in a stopped state, there is a detection frame in a hidden state in the image currently on the security officer's interpretation screen.

[0037] ​(4) the current interpretation result is open inspection, release, and timeout, and the security officer interprets the image on the screen and finds a detection frame in a hidden state.

[0038] S4, the X-ray machine 21 stores the detection result image, the interpretation result, the open inspection frame, and the detection frame to the data server 23, and the management type workstation 24 obtains the image, the interpretation result, the open inspection frame, and the detection frame from the data server 23, analyzes the image, the interpretation result, the open inspection frame, and the detection frame, judges whether the security officer has the condition of relying on the detection frame for interpretation (for example, the conditions (2) and (4) of step S3 correspond to the condition that the security officer relies on the detection frame to find the prohibited articles, and other conditions can be defined by the user), and whether the security officer and the intelligent detection system have the condition of missing detection, and the condition can be corrected and processed according to the analysis result.

[0039] For those skilled in the art, various corresponding changes and modifications can be given according to the above technical solutions and concepts, and all these changes and modifications should be included in the protection scope of the claims of the present application.
