[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0040] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0041] In addition, if the embodiments of the present application involve descriptions such as “first”, “second”, etc., the descriptions of “first”, “second”, etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first” and “second” can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection claimed by the present application.

[0042] In addition, it should be understood that in the security check scene, in order to maintain public safety and protect the interests of the traveling personnel, the face information of the security check personnel will be collected during the security check process, so as to facilitate the association and backtracking of the security check information, and the above are performed under the condition that the security check personnel are aware and legal.

[0043] As described in the background, at present, the functions of common security check machines are relatively single, and they cannot assist in realizing the association between different baggage information in the transportation process, and therefore, it is necessary to improve the existing security check machines.

[0044] In order to solve the above problems, as shown in the Figure 1 The security check machine 1 provided by the embodiments of the present application includes a support frame body 11, a ray source (not shown in the figure), a detector (not shown in the figure), a transmission assembly 12 and a radio frequency identification assembly 13.

[0045] The support frame body 11 forms a security check channel inside. The transmission assembly 12 can be a conveyor belt. The object to be inspected 14 can be transported through the security check channel through the transmission assembly 12, and the object to be inspected 14 can be subjected to security check in the security check channel.

[0046] The ray source, the detector and the radio frequency identification component 13 are arranged on the support frame body 11 respectively, and the arrangement position of the radio frequency identification component 13 on the support frame body 11 is not overlapped with the arrangement position of the ray source and the detector on the support frame body 11. The ray source can output detection rays, such as X-ray. The detector can collect ray detection images, which can be X-ray detection images. The radio frequency identification component 13 is used to identify radio frequency tags on the to-be-detected object 14 transmitted into the security check channel by the transmission component 12.

[0047] In one example, the to-be-detected object 14 can be luggage 142, and the radio frequency tag is arranged on the luggage 142.

[0048] In another example, the to-be-detected object 14 can be luggage 142 and a tray 141 for carrying the luggage 142, and the radio frequency tag is arranged on the tray 141, but not on the luggage 142.

[0049] The security check machine 1 described above comprises a support frame body 11, a ray source, a detector, a transmission component 12 and a radio frequency identification component 13. The support frame body 11 forms a security check channel inside. The ray source, the detector and the radio frequency identification component 13 are arranged on the support frame body 11 respectively. The ray source performs ray detection on the to-be-detected object 14 inside the security check channel. The detector collects ray detection images of the to-be-detected object 14 to realize detection of the to-be-detected object 14. The radio frequency identification component 13 identifies radio frequency tags on the to-be-detected object 14 transmitted into the security check channel by the transmission component 12. The radio frequency identification component 13 and the security check machine are configured to have an association relationship, so that the radio frequency tags of the to-be-detected object 14 can be associated with the ray detection images of the to-be-detected object 14. The radio frequency tags on the to-be-detected object 14 can be pre-associated with the information of the person 5 under security check, and the radio frequency tags can also be pre-associated with the visible light images of the to-be-detected object, so as to realize the association among the information of the person 5 under security check, the ray detection images of the to-be-detected object 14 and the visible light images of the to-be-detected object by the security check machine 1.

[0050] In one embodiment, as shown in Figure 2 and Figure 3 The radio frequency identification component 13 comprises a radio frequency reader 131 and a mounting shell 132, and the radio frequency reader 131 is located in the mounting shell 132.

[0051] It can be understood that the radio frequency reader 131 is the core component of the radio frequency identification assembly 13, and the radio frequency reader 131 is used to identify the identification information stored in the label on the to-be-inspected object 14 or the tray 141. By accommodating the radio frequency reader 131 in the installation shell 132, the radio frequency reader 131 can be effectively prevented from being affected by external environmental factors (such as dust, moisture, collision, etc.), and the stable and reliable operation of the radio frequency reader 131 can be ensured. At the same time, since the installation shell 132 is detachably installed on the inner wall of the security check channel, the staff can conveniently detach the installation shell 132 from the inner wall of the security check channel to perform maintenance, replacement or upgrading operations on the internal radio frequency reader 131.

[0052] In one embodiment, as shown in Figure 2 and Figure 3 , the installation shell 132 is provided with a receiving groove 1321 and a mounting opening 1322, and the radio frequency reader 131 is adapted to be mounted in the receiving groove 1321 through the mounting opening 1322.

[0053] It can be understood that the installation shell 132 plays an important role in protecting and installing the radio frequency reader 131 in the entire security check system. The receiving groove 1321 is the accommodation space of the radio frequency reader 131, and the size and shape of the receiving groove 1321 are accurately matched with the outer shape of the radio frequency reader 131. The radio frequency reader 131 can be provided with a stable placement position to ensure that the radio frequency reader 131 will not shake or shift during operation, thereby ensuring that the radio frequency reader 131 can operate stably and reliably.

[0054] The mounting opening 1322 is a channel for the radio frequency reader 131 to enter the receiving groove 1321. The design of this opening fully considers the installation convenience of the radio frequency reader 131. The radio frequency reader 131 can be smoothly installed into the receiving groove 1321 through this mounting opening 1322. During installation, the staff can easily and accurately place the radio frequency reader 131 into the receiving groove 1321 along the direction of the mounting opening 1322 without complicated operation steps. In addition, this design not only facilitates the installation of the radio frequency reader 131, but also allows the staff to conveniently take out the radio frequency reader 131 from the receiving groove 1321 through this mounting opening 1322 when subsequent maintenance, replacement or upgrading of the radio frequency reader 131 is required. The entire process is simple and fast, greatly improving the efficiency of equipment maintenance, reducing maintenance costs and time, and reflecting the rationality and practicality of the design of the installation shell 132.

[0055] In one embodiment, as shown in Figure 4 and Figure 5As shown, the mounting shell 132 comprises a main shell 1323 and a cover 1324, the main shell 1323 is provided with a receiving groove 1321 and a mounting opening 1322, the radio frequency reader 131 is adapted to be mounted in the receiving groove 1321 through the mounting opening 1322, and the cover 1324 is adapted to be clamped in the mounting opening 1322.

[0056] It can be understood that the receiving groove 1321 provided on the main shell 1323 is mainly used to provide a mounting space for the radio frequency reader 131. The mounting interface provided on the main shell 1323 and communicating with the receiving groove 1321 can enable the radio frequency reader 131 to be mounted in the receiving groove 1321 through the mounting interface, so as to facilitate the mounting of the radio frequency reader 131 in the mounting shell 132. By making the shape of the cover 1324 completely match the mounting interface, it can be ensured that the cover 1324 forms a complete and sealed whole structure with the main shell 1323 after being mounted, so as to effectively protect the internal radio frequency reader 131 from the influence of external environmental factors (such as dust, humidity, electromagnetic interference, etc.). In addition, clamping is a simple and effective connection method, and the cover 1324 is mounted on the mounting interface in a clamping manner, so that the process of mounting the cover 1324 on the mounting interface is convenient and fast. In addition, when it is necessary to maintain or replace the radio frequency reader 131, the cover 1324 can also be easily detached from the mounting interface, which greatly improves the maintainability of the mounting shell 132 and the radio frequency reader 131.

[0057] In one example, the mounting shell 132 is threadedly connected or clamped with the inner wall of the security passage.

[0058] In one example, the mounting shell 132 is threadedly connected with the inner wall of the security passage. In order to realize the threaded connection of the mounting shell 132 and the inner wall of the security passage, threaded holes matched with each other can be respectively machined on the inner wall of the security passage and the mounting shell 132. When it is necessary to install, the threaded holes on the mounting shell 132 are matched with the threaded holes on the inner wall of the security passage, and a screw is used to connect the threaded holes on the mounting shell 132 and the threaded holes on the inner wall of the security passage, so that the mounting shell 132 is threadedly connected with the inner wall of the security passage. It can be understood that the threaded connection has high connection strength and stability. After the mounting shell 132 is threadedly connected with the inner wall of the security passage, it is difficult for the mounting shell 132 to loosen in the normal use process, which can ensure that the mounting shell 132 works stably in the security passage for a long time. Moreover, the threaded connection is convenient for dismounting and re-mounting. If it is necessary to repair or replace the equipment in the mounting shell 132, the mounting shell 132 can be removed by using a corresponding tool, and the operation is relatively simple.

[0059] In another example, the installation housing 132 is clamped to the inner wall of the security passageway. In order to achieve the clamping of the installation housing 132 to the inner wall of the security passageway, a clamping part (a clamping groove or a clamping hook with a specific shape) can be arranged on the inner wall of the security passageway, and a clamping block or a clamping hole corresponding to the clamping part is designed on the installation housing 132. During installation, the clamping block or the clamping hole on the installation housing 132 is aligned with the clamping groove or the clamping hook on the inner wall of the security passageway, and then a certain external force (such as pressing, pushing, etc.) is applied to make them clamped to each other, thereby achieving the connection between the installation housing 132 and the inner wall of the security passageway. It can be understood that the biggest advantage of the clamping mode is that the installation and disassembly are fast, no tools are needed, and the operation is simple and convenient. In the case of needing to quickly install or replace the installation housing 132, the clamping mode can greatly improve the work efficiency.

[0060] In one embodiment, as shown in Figure 3 and Figure 4 , the inner wall of the security passageway is provided with a mounting groove 1325 adapted to the installation housing 132, and the installation housing 132 can be detachably installed in the mounting groove 1325.

[0061] In the design of the security passageway, in order to achieve stable and convenient installation of the installation housing 132 in the third identification mechanism, a mounting groove 1325 is specially arranged on the inner wall of the security passageway. The design size and shape of this mounting groove 1325 are adapted to the installation housing 132, and it can perfectly accommodate the installation housing 132, thereby facilitating the installation of the installation housing 132 and achieving the fool-proof design.

[0062] In one embodiment, the distance between the setting position of the radio frequency identification assembly 13 on the support frame body 11 and the light slot position of the ray source is less than the distance threshold.

[0063] It can be understood that, since the distance between the setting position of the radio frequency identification assembly 13 on the support frame body 11 and the light slot position of the ray source is less than the distance threshold, the distance between the radio frequency identification assembly 13 and the light slot position of the ray source is small, the time nodes of the probe collecting the ray detection image of the object 14 and the radio frequency identification assembly 13 identifying the radio frequency tag of the object 14 are close, and the radio frequency tag and the ray detection image can be associated by the collection time, which is beneficial to improve the association accuracy between the radio frequency tag and the ray detection image corresponding to the same luggage 142 in the ray scanning detection process.

[0064] As shown in Figure 6 , the application also provides a security inspection system, which comprises the security inspection machine 1, the luggage arrangement table 2 and the conveying device 3 according to any one of the above embodiments.

[0065] The luggage sorting table 2 is provided with a first radio frequency identifier 21 and a first visible light image acquisition assembly 22, and the first radio frequency identifier 21 and the first visible light image acquisition assembly 22 are configured in association. The first radio frequency identifier 21 can identify the radio frequency tag on the object 14 to be inspected. The first visible light image acquisition assembly 22 can be a visible light camera, and the first visible light image acquisition assembly 22 can acquire the face image of the security personnel 5 or the visible light image of the object 14 to be inspected.

[0066] In the application, the luggage sorting table 2 is a platform for the security personnel 5 to sort the luggage 142, and the luggage sorting table 2 includes a plurality of luggage 142 sorting positions. Each luggage 142 sorting position can be provided with a tray 141, so that the security personnel 5 can place the luggage 142 on the tray 141. Correspondingly, each luggage 142 sorting position can be provided with a first radio frequency identifier 21 and a first visible light image acquisition assembly 22.

[0067] For example, the luggage sorting table 2 can include three luggage 142 sorting positions, i.e., a luggage 142 sorting position, a luggage 142 sorting position, and a luggage 142 sorting position. The security personnel a places the luggage 142 on the tray 141 at the luggage 142 sorting position. In this process, the first visible light image acquisition assembly 22 corresponding to the luggage 142 sorting position acquires the face image of the security personnel a, and the first radio frequency identifier 21 corresponding to the luggage 142 sorting position identifies the radio frequency tag on the tray 141. After the security personnel a places the luggage 142 on the tray 141, the security personnel a can place the tray 141 with the luggage 142 on the conveying assembly 12, and then go to the security gate for personnel security check.

[0068] According to the transmission direction of the luggage 142, the luggage sorting table 2 is arranged upstream of the security inspection machine 1, and a conveying device 3 is arranged between the luggage sorting table 2 and the security inspection machine 1. The conveying device 3 is provided with a second radio frequency identifier 31, and the entrance end of the security inspection machine 1 is provided with a second visible light image acquisition assembly 4. The second radio frequency identifier 31 and the second visible light image acquisition assembly 4 are configured in association. The second radio frequency identifier 31 can identify the radio frequency tag on the object 14 to be inspected. The second visible light image acquisition assembly 4 can be a visible light camera, and the second visible light image acquisition assembly 4 can acquire the visible light image of the object 14 to be inspected.

[0069] It can be understood that the first radio frequency identifier 21 and the first visible light image acquisition component 22 are configured to have an association relationship, and then the image acquired by the first visible light image acquisition component 22 can be associated with the radio frequency tag on the object 14. In the case that the first visible light image acquisition component 22 acquires the face image of the person 5 to be checked, the face image of the person 5 to be checked can be associated with the radio frequency tag on the object 14. Similarly, the second radio frequency identifier 31 and the second visible light image acquisition component 4 are configured to have an association relationship, and then the image acquired by the second visible light image acquisition component 4 can be associated with the radio frequency tag on the object 14, that is, the visible light image of the object 14 can be associated with the radio frequency tag on the object 14. Since the coding information stored in the radio frequency tag on the object 14 is unique, based on the same radio frequency tag, the face image of the person 5 to be checked and the visible light image of the object 14 can be associated. Since the radio frequency tag of the object 14 can be associated with the radiographic image of the object 14 through the security inspection machine 1, based on the same radio frequency tag, the radio frequency tag of the object 14, the face image of the person 5 to be checked, the visible light image of the object 14, and the radiographic image of the object 14 can be associated, thereby realizing the multi-dimensional information association of the person and the object 14.

[0070] The above security inspection system comprises the security inspection machine 1, the luggage arrangement table 2 and the conveying mechanism according to any one of the above embodiments. The first radio frequency identifier 21 and the first visible light image acquisition component 22 are arranged on the luggage arrangement table 2, and then the first radio frequency identifier 21 can identify the radio frequency tag of the object 14, and the first visible light image acquisition component 22 can acquire the face image of the person 5 to be checked. Since the first radio frequency identifier 21 and the first visible light image acquisition component 22 are configured to have an association relationship, the face image of the person 5 to be checked can be associated with the radio frequency tag of the object 14. The conveying device 3 is arranged between the luggage arrangement table 2 and the security inspection machine 1, the second radio frequency identifier 31 is arranged on the conveying device 3, and the second visible light image acquisition component 4 is arranged at the entrance end of the security inspection machine 1. The second radio frequency identifier 31 can identify the radio frequency tag of the object 14 in transportation, and the second visible light image acquisition component 4 can acquire the visible light image of the object 14. Since the second radio frequency identifier 31 and the second visible light image acquisition component 4 are configured to have an association relationship, the radio frequency tag of the object 14 can be associated with the visible light image of the object 14, and the radio frequency tag of the object 14 can be associated with the radiographic image of the object 14 through the security inspection machine 1. In summary, based on the radio frequency tag of the object 14, the radio frequency tag of the object 14, the face image of the person 5 to be checked, the visible light image of the object 14, and the radiographic image of the object 14 can be associated through the security inspection system of the embodiment, thereby realizing the multi-dimensional information association of the person and the object 14, and improving the association accuracy.

[0071] In one embodiment, as shown in Figure 7 A third radio frequency identifier 32 can also be arranged on the conveying device 3, and the third radio frequency identifier 32 can be arranged at the exit of the security check channel. The third radio frequency identifier 32 is configured to identify the radio frequency tag on the object 14 to be checked.

[0072] It can be understood that, by arranging the third radio frequency identifier 32 outside the security check channel, and identifying the radio frequency tag on the object 14 to be checked by the third radio frequency identifier 32, it can be detected whether the carrying tray 141 carrying the luggage 142 exits the security check channel, and the tracking detection of the luggage 142 can be realized, so that the tracking detection of the luggage 142 is less affected by the running state of the conveying assembly 12.

[0073] In addition, in combination with the above-mentioned embodiments, in the case where the security check system includes the radio frequency identification assembly 13, the first radio frequency identifier 21, the second radio frequency identifier 31, and the third radio frequency identifier 32, the security check system can perform full-process tracking recording on the object 14 to be checked, i.e., full-process tracking recording on the luggage 142, so as to reduce the risk of loss of the luggage 142, and facilitate to improve the accuracy of full-process association matching of the personnel and the luggage 142.

[0074] In one embodiment, as shown in Figure 7 The security check machine 1 system further includes a security check door 6, and the security check door 6 is provided with a third visible light image acquisition assembly 61. The acquisition angle range of the third visible light image acquisition assembly 61 covers the detection area corresponding to the security check door 6.

[0079] It can be understood that the first visible light image acquisition component 22, the third visible light image acquisition component 61, and the fourth visible light image acquisition component 71 acquire the face image of the security inspection personnel 5 respectively. Then, the face similarity can be used for matching to determine the face image of the same security inspection personnel 5, and the relevant information associated with the face image of the security inspection personnel 5 is associated with each other. Thus, the certificate information of the security inspection personnel 5, the ray detection image of the object 14 to be inspected, the radio frequency tag on the object 14 to be inspected, the visible light image of the object 14 to be inspected, and the personnel scanning result can be associated, thereby realizing the whole-process association of the security inspection personnel 5 on the security inspection path, improving the accuracy of the whole-process association and matching of the personnel and the luggage 142, and helping to maintain public security.

[0080] In one embodiment, the security inspection machine 1 system further includes a processing platform, which is in communication connection with other components in the security inspection system.

[0081] The other components include at least part of the security inspection machine 1, the first radio frequency identifier 21, the first visible light image acquisition component 22, the second radio frequency identifier 31, the second visible light image acquisition component 4, the security door 6, the third visible light image acquisition component 61, the gate 7, and the fourth visible light image acquisition component 71.

[0082] In the application, the gate 7, the security inspection machine 1, and the security door 6 can be arranged on the security inspection path in sequence, and the security inspection personnel 5 can pass through the gate 7, the security inspection machine 1, and the security door 6 in sequence. Illustratively, the gate 7 can acquire the certificate information of the security inspection personnel 5 and release the security inspection personnel 5 based on the certificate information of the security inspection personnel 5. The gate 7 can also acquire the face image of the security inspection personnel 5 through the fourth visible light image acquisition component 71 and release the security inspection personnel 5 based on the face image of the security inspection personnel 5. The gate 7 sends the acquired certificate information or face image to the processing platform, so that the processing platform obtains the personnel information of the security inspection personnel 5.

[0083] When the security personnel 5 passes through the security machine 1, the carrying luggage 142 needs to be security checked. Exemplarily, the object to be inspected 14 can be the luggage 142 and the tray 141 for carrying the luggage 142, and at the luggage arranging table 2, the security personnel 5 needs to place the luggage 142 on the tray 141, in the process, the first visible light image acquisition assembly 22 can acquire the face image of the security personnel 5, and send the face image of the security personnel 5 to the processing platform, the first radio frequency identifier 21 can identify the radio frequency tag on the object to be inspected 14, and send the radio frequency tag on the object to be inspected 14 to the processing platform, and the processing platform can associate the face image of the security personnel 5 and the radio frequency tag on the object to be inspected 14. After placing the tray 141 carrying the luggage 142 on the transportation assembly 12, the second visible light image acquisition assembly 4 can acquire the visible light image of the object to be inspected 14, and send the acquired visible light image of the object to be inspected 14 to the processing platform, the second radio frequency identifier 31 can identify the radio frequency tag on the object to be inspected 14, and send the radio frequency tag on the object to be inspected 14 to the processing platform, and the processing platform can associate the visible light image of the object to be inspected 14 and the radio frequency tag on the object to be inspected 14. In the process of transporting the object to be inspected 14 through the security channel, the detector of the security machine 1 acquires the ray detection image of the object to be inspected 14 in the security channel and sends it to the processing platform, the radio frequency identification assembly 13 identifies the radio frequency tag on the object to be inspected 14 and sends it to the processing platform, and the processing platform associates the ray detection image of the object to be inspected 14 with the radio frequency tag on the object to be inspected 14. Then, based on the same radio frequency tag, the processing platform can associate the corresponding face image of the security personnel 5, the visible light image of the object to be inspected 14 and the ray detection image of the object to be inspected 14.

[0084] After the security personnel 5 places the luggage 142 on the luggage 142 security checking device for security checking of the luggage 142, the security personnel 5 can pass through the security door 6, the security door 6 can scan the security personnel 5 to obtain the personnel security checking result of the security personnel 5, and acquire the face image of the security personnel 5, and then send it to the processing platform, and the processing platform associates the face image of the security personnel 5 with the personnel security checking result. Finally, the face image corresponding to the same security personnel 5 is determined, and based on the face image of the same security personnel 5, the personnel information (such as identification information) corresponding to the security personnel 5, the ray detection image of the object to be inspected 14, the radio frequency tag of the object to be inspected 14, the visible light image of the object to be inspected 14 and the personnel security checking result are associated, and the multi-dimensional information corresponding to the security personnel 5 is associated on the security path, so that the security personnel 5 is associated throughout the security path, and the accuracy of the whole process association and matching of the personnel and the luggage 142 is improved.

[0085] Based on the foregoing embodiments, in one embodiment, the security checking process can be as follows:

[0086] First step: the security personnel at the entrance of the terminal pass through the anti-explosion gate (the anti-explosion gate includes a certificate collection device), swipe the ID card for verification, and after verification, the gate sends the personnel certificate information to the processing platform, including the face image (first identity feature information). After receiving the personnel certificate information, the processing platform adds the personnel to the list library.

[0087] Second step: after checking in, the security personnel arrive at the security machine, and in the security machine, the transportation assembly is a conveyor belt. The security personnel takes the tray and puts it on the luggage sorting table, and the tray is pasted with an RFID tag (radio frequency tag), and the RFID tag code of each tray is unique. An RFID reader is placed near the luggage sorting table, the entrance of the security machine, the internal x-ray scanning line of the security machine, and the exit of the security machine. The processing platform accesses the face shooting camera (first visible light image collection assembly) on the luggage sorting table, the face collection site RFID reader (first radio frequency identifier), the visible light shooting camera (second visible light image collection assembly), the visible light collection site RFID reader (second radio frequency identifier), the security machine and the internal RFID reader of the security machine (radio frequency identification assembly), and the end RFID reader (third radio frequency identifier). The processing platform binds the face shooting camera and the face collection site RFID reader one by one, binds the visible light shooting camera and the visible light collection site RFID reader, and binds the RFID reader in the security machine and the security machine.

[0088] Third step, after the tray is placed on the luggage sorting table, the RFID tag in the tray is recognized and read by the corresponding face collection site RFID reader, and the RFID tag code is reported to the processing platform, and the platform records this time as t. When the tray is placed on the luggage sorting table, the RFID reader continuously reports the RFID tag code to the processing platform, and the corresponding face shooting camera also continuously collects. The security personnel places the luggage in the tray, and after finishing the arrangement, pushes the tray into the conveyor belt. The processing platform records the last time the RFID tag code is reported to the platform in this time period as t (t, t is the two time points of pushing the tray into the luggage sorting table and pushing the tray out of the luggage sorting table), and the platform queries the best face recognized by the corresponding face shooting camera of the face collection site RFID reader in the t-t time period as the face photo (second identity feature information) of the security personnel, and simultaneously uses the face photo to compare with the security personnel in the list library to obtain the identity information of the current security personnel. Thus, the association relationship of

security personnel identity information

[0089] Fourth step, the tray moves forward under the action of the conveyor belt, and when passing through the visible light collection site RFID reader, the RFID tag on the tray is identified and reported to the processing platform, the processing platform queries the corresponding associated visible light shooting camera, actively triggers collection, obtains the visible light luggage picture (visible light image of the object to be inspected), and thus the processing platform has the association relationship of

RFID mark code

[0090] Fifth step, based on the same RFID code of the same tray, the face photo and the visible light image of the luggage can be associated at this time. The tray continues to move and passes through the security inspection machine, and the security inspection machine reports the x-ray luggage picture (ray detection image) and the scanning start time t and the scanning end time t. During the scanning of the tray by the security inspection machine, the RFID reader inside the security inspection machine identifies the tag on the tray and reports to the platform, and the platform records the RFID tag identification time and the RFID mark code and saves them to the database. When the processing platform receives the x-ray picture, it queries the RFID tag code recorded in the database within the scanning time period (t to t) and associates them, and thus the platform has the association relationship of

security inspection personnel identity information

[0092] Seventh step, while the tray is scanned by the security inspection machine, the security inspection personnel is checked by the security inspection door, and the personnel security inspection result of the security inspection personnel is obtained. A personnel shooting camera (third visible light image acquisition component) is arranged at the exit of the security inspection door. When the security inspection personnel enters the security inspection door, the face is automatically collected and displayed on the operation table. The security inspection personnel selects the corresponding face collection picture according to the current security inspection personnel to be inspected, and performs a scanning operation. The scanning device uploads the scanning result and the associated face collection picture (third identity feature information) to the processing platform. The processing platform uses the face photo to compare with the security inspection personnel in the name library, and obtains the identity information of the current security inspection personnel. At this time, the correlation relationship of
