DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are given the same reference numerals and the description will be omitted as appropriate.

[0010] <First embodiment> "overview" As shown in Fig. 1, the inspection system 10 of this embodiment includes a server 1, a detection device 2, and an individual specific information acquisition device 3. The detection device 2 and the individual specific information acquisition device 3 are installed in any facility where a possession inspection is required. Examples of the facility include, but are not limited to, buildings, companies, amusement facilities, airports, stations, etc. The installation location of the server 1 is not particularly limited.

[0011] The detection device 2 executes a process of detecting the object to be detected from the test subject based on a signal of a reflected electromagnetic wave with a wavelength of 30 micrometers or more and 1 meter or less. The individual specific information acquisition device 3 acquires individual specific information specific to the test subject from the test subject before the above process is executed by the detection device 2. The server 1 determines the contents of the possession inspection for each test subject based on the individual specific information. For example, the server 1 determines whether or not to execute a possession inspection and the type of object to be detected for each test subject based on the individual specific information. Then, the server 1 executes a predetermined process so that the possession inspection for each test subject has the determined contents.

[0012] According to the inspection system 10 of the present embodiment, it is possible to perform a possession inspection of each of a plurality of subjects, with the contents appropriate to the individual's unique information. For example, for a person who has a low need for a possession inspection, such as a police officer or a child, it is possible to not perform a possession inspection or to reduce the types of objects to be detected. On the other hand, for a person who has a high need for a possession inspection, it is possible to perform a possession inspection or to increase the types of objects to be detected. In this way, by adjusting the inspection contents according to the necessity of the possession inspection, the possession inspection becomes more efficient and the waiting time for the inspection is shortened.

[0013] "Hardware Configuration" Next, an example of the hardware configuration of the inspection system 10 will be described. Fig. 2 is a diagram showing an example of the hardware configuration of the inspection system 10. Each functional unit of the inspection system 10 is realized by any combination of hardware and software, centering on a CPU (Central Processing Unit) of any computer, memory, programs loaded into the memory, a storage unit such as a hard disk for storing the programs (programs stored beforehand at the stage of shipping the device, as well as programs downloaded from storage media such as a CD (Compact Disc) or a server on the Internet, can be stored), and a network connection interface. Those skilled in the art will understand that there are various variations in the realization method and device.

[0014] As shown in Fig. 2, the inspection system 10 has a processor 1A, a memory 2A, an input / output interface 3A, a peripheral circuit 4A, and a bus 5A. The peripheral circuit 4A includes various modules. The inspection system 10 does not have to have the peripheral circuit 4A. Note that the inspection system 10 may be composed of multiple devices that are physically and / or logically separated. When composed of multiple devices that are physically and / or logically separated, each of the multiple devices can have the above hardware configuration.

[0015] The bus 5A is a data transmission path for the processor 1A, memory 2A, peripheral circuit 4A, and input / output interface 3A to transmit and receive data to each other. The processor 1A is an arithmetic processing device such as a CPU or a GPU (Graphics Processing Unit). The memory 2A is a memory such as a RAM (Random Access Memory) or a ROM (Read Only Memory). The input / output interface 3A includes an interface for acquiring information from an input device, an external device, an external server, an external sensor, an electromagnetic wave transmitting / receiving device, etc., and an interface for outputting information to an output device, an external device, an external server, an electromagnetic wave transmitting / receiving device, etc. Examples of the input device include a keyboard, a mouse, a microphone, etc. Examples of the output device include a display, a speaker, a printer, a mailer, etc. The processor 1A can issue commands to each module and perform calculations based on the results of those calculations.

[0016] "Function Configuration" Next, a description will be given of the functional configuration of the inspection system 10. An example of a functional block diagram of the inspection system 10 is shown in Fig. 3. As shown in the figure, the inspection system 10 has an acquisition unit 11, a determination unit 12, a detection unit 13, an electromagnetic wave transmission / reception unit 14, and a storage unit 15.

[0017] These functional units are provided in any one of the server 1, the detection device 2, and the individual specific information acquisition device 3 in Fig. 1. There is no particular restriction as to which device has each functional unit, and various patterns can be adopted. For example, the acquisition unit 11 may be realized by the server 1 and the individual specific information acquisition device 3, the electromagnetic wave transmission / reception unit 14 may be realized by the detection device 2, the determination unit 12 and the memory unit 15 may be realized by the server 1, and the detection unit 13 may be realized by the server 1 or the detection device 2. The configuration of each functional unit will be described below.

[0018] The electromagnetic wave transmitting / receiving unit 14 irradiates electromagnetic waves (e.g., microwaves, millimeter waves, terahertz waves, etc.) with a wavelength of 30 micrometers or more and 1 meter or less toward the subject of inspection who is present in a predetermined area, and receives the reflected waves. The electromagnetic wave transmitting / receiving unit 14 is, for example, a radar. The electromagnetic wave transmitting / receiving unit 14 can be configured using any technology. For example, as in the example of FIG. 4, the electromagnetic wave transmitting / receiving unit 14 may be a sensor panel configured with a radar in which multiple antenna elements are arranged. Note that the panel is just one example, and the electromagnetic wave transmitting / receiving unit 14 may be configured in other ways, such as a gate through which the subject of inspection passes, or a booth into which the subject of inspection enters.

[0019] The detection unit 13 performs a detection process to detect an abnormal state based on a signal of a reflected wave received by the electromagnetic wave transmission / reception unit 14. In this embodiment, the abnormal state is a state in which a person present in a predetermined area is carrying a preset detection object. The detection object is, for example, an object that is prohibited from being brought in, and examples of the detection object include, but are not limited to, a gun, a knife, a camera, a plastic bottle, etc. An example of the judgment process will be described below.

[0020] -First judgment processing example- In this example, the detection unit 13 creates a transmission image based on the signal of the reflected wave received by the electromagnetic wave transmission / reception unit 14. Then, the detection unit 13 detects the detection object from the transmission image based on the shape of the object that appears in the transmission image. When the detection object is detected from the transmission image, it is determined that the subject in the specified area is carrying the detected detection object.

[0021] Through advance preparation, feature amounts of the shapes of the respective objects are generated and registered in the inspection system 10. The detection unit 13 detects the object to be detected from the transmission image based on a result of matching between feature amounts of the shape of the object to be detected and feature amounts of the shape appearing in the transmission image. These processes by the detection unit 13 may be realized by using an estimation model generated by machine learning based on teacher data consisting of transmission images and labels of the multiple objects, or may be realized by template matching.

[0022] -Second judgment processing example- In this example, the detection unit 13 judges whether the subject in the predetermined area is carrying the detection object based on a feature (reflected wave feature) that appears in the reflected wave signal received by the electromagnetic wave transmission / reception unit 14. When a reflected wave feature that is specific to the detection object is detected from the reflected wave signal, it is judged that the subject in the predetermined area is carrying the detected detection object.

[0023] Through advance preparation, reflected wave features of each of a plurality of objects are generated and registered in the inspection system 10. The detection unit 13 detects reflected wave features specific to the object from the reflected wave signal based on a comparison result between the reflected wave features of the object and features appearing in the reflected wave signal. These processes by the detection unit 13 may be realized by using an estimation model generated by machine learning based on training data consisting of the reflected wave signals and labels of a plurality of objects, or may be realized by template matching.

[0024] The detection unit 13 can output the detection result via a predetermined output device (display, speaker, warning lamp, projection device, etc.). The output device may be installed, for example, at the inspection site, and may be configured to present predetermined information to the person being inspected or the manager who manages the inspection. Furthermore, the detection unit 13 may change the output mode of the output device depending on the contents of the detection result (whether or not the object to be detected has been detected). There are various ways of outputting, and any means can be adopted in this embodiment.

[0025] The acquisition unit 11 acquires individual specific information specific to each test subject before a test (the above-mentioned test realized by the detection unit 13 and the electromagnetic wave transmission / reception unit 14) is performed on the test subject. The individual specific information in this embodiment is information indicating a group to which each test subject belongs.

[0026] The groups are defined by at least one of the following: occupation, affiliation within a given organization, gender, age group, and whether or not data has been registered in advance. Examples include, but are not limited to, "group of people under 10 years old," "group of police officers," "group of security guards," "group of cleaners," "group of women in department A," "group of men in department A," "group of directors," "group of bodyguards," and "group of people not registered in the database."

[0027] The acquisition unit 11 acquires at least one of subject identification information for identifying a plurality of subjects, information on personal belongings held by the subject, information on clothing of the subject, and attributes of the subject estimated from an image, and identifies a group to which the subject belongs based on the acquired information. An example will be described below.

[0028] -First group specific processing example- In this example, subject identification information is assigned in advance to each of a plurality of people, and the storage unit 15 stores linking information linking the subject identification information with the group to which each test subject belongs.

[0029] The acquisition unit 11 then acquires subject identification information from each person being examined. The subject identification information may be any technology capable of identifying multiple people from one another. For example, the subject identification information may be characteristic information possessed by each person, such as face information (such as a face image or an appearance feature amount extracted from a face image), fingerprint information, voiceprint information, iris information, gait information, etc. Alternatively, the subject identification information may be information created for each person, such as an arrangement of numbers, letters, etc.

[0030] When the subject identification information is face information, iris information, gait information, or the like, the acquisition unit 11 is configured to include an imaging device such as a camera. When the subject identification information is fingerprint information, the acquisition unit 11 is configured to include a fingerprint sensor (fingerprint reading device). When the subject identification information is a voiceprint, the acquisition unit 11 is configured to include a microphone. When the subject identification information is information in which numbers, letters, or the like are arranged, the acquisition unit 11 is configured to include an input device such as a short-range wireless communication device, a code reader, a touch panel, a keyboard, a physical button, a microphone, a camera, or the like.

[0031] In this example, the acquisition unit 11 identifies the group to which each test subject belongs, based on the subject identification information acquired from each test subject and the linking information stored in the storage unit 15.

[0032] It should be noted that test subjects who do not have subject identification information may be identified as belonging to the "group of people not registered in the database."

[0033] -Second group specific processing example- In this example, the acquisition unit 11 is configured to include an imaging device such as a camera. The acquisition unit 11 analyzes an image including the subject of inspection, and acquires at least one of information on belongings held by the subject of inspection and information on the clothing of the subject of inspection. Then, based on this information, the acquisition unit 11 estimates the subject of inspection's occupation, affiliation within a specified organization, etc. Specifically, based on the uniform, badge, belongings, etc., the person's occupation, affiliation within a specified organization, etc. are estimated.

[0034] The characteristic amounts of belongings and clothing specific to each person for each occupation, affiliation within a specific organization, etc. are stored in advance in the storage unit 15. The acquisition unit 11 analyzes an image of the test subject and detects these characteristic amounts to estimate the test subject's occupation, affiliation within a specific organization, etc.

[0035] -Third group specific processing example- In this example, the acquisition unit 11 includes an imaging device such as a camera. The acquisition unit 11 analyzes an image including the test subject and estimates the attributes of the test subject. Then, the acquisition unit 11 identifies a group to which the test subject belongs based on the estimated attributes. The estimated attributes include age group, sex, etc. Technology for estimating these attributes through image analysis is widely known, so a description thereof will be omitted here.

[0036] -Fourth group specific processing example- In this example, any two or more of the first to third group identification process examples are combined to identify the group to which the test subject belongs.

[0037] The determination unit 12 determines the contents of the possession inspection for each inspection subject based on the individual specific information acquired by the acquisition unit 11. An example will be described below.

[0038] -First content decision example- In this example, the determination unit 12 determines whether or not to carry out a baggage search for each test subject based on the individual specific information. For example, groups are defined as shown in Fig. 5, and whether or not to carry out a baggage search for each group is defined as shown in Fig. 6. The information shown in Figs. 5 and 6 is stored in the storage unit 15.

[0039] As shown in Figure 6, the decision unit 12 decides whether or not to conduct a baggage search for each person to be tested, based on group information that defines the content of the baggage search for each group in advance and the individual-specific information (information indicating the group to which the person to be tested belongs) acquired by the acquisition unit 11.

[0040] In this example, the determination unit 12 can output the determined content, i.e., whether or not to conduct a baggage search, via a predetermined output device (such as a display, speaker, lamp, or projection device). The output device may be installed, for example, at the inspection site, and may be configured to present predetermined information to the person being inspected and an administrator who manages the inspection.

[0041] In this way, a person subject to inspection who is determined not to undergo a baggage inspection can pass through the inspection area without passing through a location where electromagnetic waves are irradiated by the electromagnetic wave transmitting / receiving unit 14 (in front of a panel, a gate, a booth, etc.).

[0042] Note that even if a person is judged not to undergo a baggage inspection, he or she will pass through a position (in front of a panel, a gate, a booth, etc.) where electromagnetic waves are irradiated by the electromagnetic wave transmitting and receiving unit 14, but the irradiation of electromagnetic waves and reception of reflected waves may not be performed on that person (controlling the electromagnetic wave transmitting and receiving unit 14). In addition, the device may be configured to irradiate electromagnetic waves and receive reflected waves from a person who is judged not to undergo a baggage inspection, but not to detect a detection target based on the signal of the reflected wave (controlling the detection unit 13). In addition, the device may be configured to detect detection targets for a person who is judged not to undergo a baggage inspection, but not to output a warning even if a specified detection target is detected (controlling the detection unit 13).

[0043] -Second example of content decision- In this example, the determination unit 12 determines the detection target to be detected for each test subject based on the individual specific information. For example, groups are defined as shown in Fig. 5, and detection targets are defined for each group as shown in Fig. 7. The information shown in Fig. 5 and Fig. 7 is stored in the storage unit 15.

[0044] As shown in Figure 7, the determination unit 12 determines the objects (detection objects) to be detected in the baggage search for each test subject based on group information that predefines the content of the baggage search for each group and the individual-specific information (information indicating the group to which the test subject belongs) acquired by the acquisition unit 11.

[0045] In this example, the determination unit 12 notifies the detection unit 13 of the determined content. The detection unit 13 executes a process of detecting the determined detection object. That is, in the case of the first determination process example described above, the detection unit 13 detects the detection object from the transmission image based on the result of matching between the shape feature of the determined detection object and the shape feature appearing in the transmission image. In addition, in the case of the second determination process example described above, the detection unit 13 detects a reflected wave feature specific to the detection object from the reflected wave signal based on the result of matching between the reflected wave feature of the determined detection object and the feature appearing in the reflected wave signal. Note that the feature (shape feature or reflected wave feature) of the object not determined as the detection object is excluded from the matching target.

[0046] -Third content decision example- In this example, the first content determination example and the second content determination example are combined. Specifically, first, based on the first content determination example, it is determined whether or not to carry out a baggage search for each inspection subject. Then, for the inspection subjects for whom it has been determined that a baggage search should be carried out, the detection objects to be detected are determined for each inspection subject based on the second content determination example.

[0047] Next, an example of the process flow of the inspection system 10 will be described with reference to the flowchart of FIG.

[0048] The inspection system 10 acquires individual specific information from the person being inspected before inspecting belongings at the inspection site (S10). For example, the inspection system 10 acquires information indicating a group to which the person being inspected belongs as the individual specific information. The inspection system 10 acquires at least one of subject identification information that distinguishes multiple subjects from each other, information on belongings held by the subject being inspected, information on the clothing of the subject being inspected, and attributes of the subject being inspected estimated from an image, and can identify the group to which the subject being inspected belongs based on the acquired information.

[0049] Next, the inspection system 10 determines the contents of the baggage inspection based on the signal of the reflected electromagnetic wave with a wavelength of 30 micrometers or more and 1 meter or less for each person to be inspected based on the individual specific information acquired in S10 (S11). For example, the inspection system 10 can determine whether or not to carry out a baggage inspection for each person to be inspected based on the individual specific information. Also, the inspection system 10 can determine the detection object to be detected for each person to be inspected based on the individual specific information.

[0050] Next, the inspection system 10 executes a predetermined process to make the baggage inspection for each inspection subject conform to the determined contents (S12). For example, the inspection system 10 presents the determined contents to the inspection subject and the manager who manages the inspection, and controls the processing contents of the detection unit 13, the electromagnetic wave transmission / reception unit 14, etc.

[0051] "Action and effect" According to the inspection system 10 of the present embodiment, it is possible to perform a possession inspection of each of a plurality of subjects, with the contents appropriate to the individual's unique information. For example, for persons who have a low need for a possession inspection, such as police officers or children, it is possible to not perform a possession inspection or to reduce the types of objects to be detected. On the other hand, for persons who have a high need for a possession inspection, it is possible to perform a possession inspection or to increase the types of objects to be detected. In this way, by adjusting the contents of the inspection according to the necessity of the possession inspection, the possession inspection becomes more efficient and the waiting time for the inspection is shortened.

[0052] <Second embodiment> This embodiment differs from the first embodiment in that the contents of the baggage inspection are determined not for each group but for each person to be inspected.

[0053] The acquisition unit 11 acquires the subject identification information described in the first embodiment as individual specific information.

[0054] The determination unit 12 determines the contents of the possession inspection for each inspection subject based on the individual specific information acquired by the acquisition unit 11. An example will be described below.

[0055] -Fourth content decision example- In this example, the determination unit 12 determines whether or not to carry out a baggage search for each test subject based on the individual specific information. For example, whether or not to carry out a baggage search is defined for each test subject identification information as shown in Fig. 9. The information shown in Fig. 9 is stored in the storage unit 15.

[0056] As shown in Figure 9, the decision unit 12 decides whether or not to conduct a baggage search for each test subject based on individual information that defines the content of the baggage search in advance for each test subject and the individual-specific information (subject identification information) acquired by the acquisition unit 11.

[0057] For a test subject who does not have subject identification information, the determination unit 12 can determine the contents of a baggage search for an unregistered person (whether or not to conduct a baggage search), which are predetermined for the unregistered person. The contents of the baggage search for an unregistered person may be determined to be that a baggage search is to be conducted.

[0058] In this example, the determination unit 12 can output the determined content, i.e., whether or not to conduct a baggage search, via a predetermined output device (such as a display, speaker, lamp, or projection device). The output device may be installed, for example, at the inspection site, and may be configured to present predetermined information to the person being inspected and an administrator who manages the inspection.

[0059] In this way, a person subject to inspection who is determined not to undergo a baggage inspection can pass through the inspection area without passing through a location where electromagnetic waves are irradiated by the electromagnetic wave transmitting / receiving unit 14 (in front of a panel, a gate, a booth, etc.).

[0060] Note that even if a person is judged not to undergo a baggage inspection, he or she will pass through a position (in front of a panel, a gate, a booth, etc.) where electromagnetic waves are irradiated by the electromagnetic wave transmitting and receiving unit 14, but the irradiation of electromagnetic waves and reception of reflected waves may not be performed on that person (controlling the electromagnetic wave transmitting and receiving unit 14). In addition, the device may be configured to irradiate electromagnetic waves and receive reflected waves from a person who is judged not to undergo a baggage inspection, but not to detect a detection target based on the signal of the reflected wave (controlling the detection unit 13). In addition, the device may be configured to detect detection targets for a person who is judged not to undergo a baggage inspection, but not to output a warning even if a specified detection target is detected (controlling the detection unit 13).

[0061] - Fifth content decision example - In this example, the determination unit 12 determines the detection target to be detected for each test subject based on the individual specific information. For example, the detection target is defined for each test subject identification information as shown in Fig. 10. The information shown in Fig. 10 is stored in the storage unit 15.

[0062] As shown in Figure 10, the determination unit 12 determines the objects (detection objects) to be detected in the baggage inspection for each test subject based on individual information that defines the content of the baggage inspection in advance for each test subject and the individual-specific information (subject identification information) acquired by the acquisition unit 11.

[0063] For a test subject who does not have test subject identification information, the determination unit 12 can determine the contents of the possession inspection (objects to be detected) that are predetermined for unregistered persons.

[0064] In this example, the determination unit 12 notifies the detection unit 13 of the determined content. The detection unit 13 executes a process of detecting the determined detection object. That is, in the case of the first determination processing example described in the first embodiment, the detection unit 13 detects the detection object from the transmission image based on the result of matching between the shape feature of the determined detection object and the shape feature appearing in the transmission image. In addition, in the case of the second determination processing example described in the first embodiment, the detection unit 13 detects a reflected wave feature specific to the detection object from the reflected wave signal based on the result of matching between the reflected wave feature of the determined detection object and the feature appearing in the reflected wave signal. Note that the feature (shape feature or reflected wave feature) of the object not determined as the detection object is excluded from the matching target.

[0065] -Sixth content decision example- In this example, the fourth content determination example and the fifth content determination example are combined. Specifically, first, based on the fourth content determination example, it is determined whether or not to carry out a baggage search for each inspection subject. Then, for the inspection subjects for whom it has been determined that a baggage search should be carried out, the objects to be detected are determined for each inspection subject based on the fifth content determination example.

[0066] Other configurations of the inspection system 10 of this embodiment are similar to those of the first embodiment.

[0067] As described above, the inspection system 10 of this embodiment achieves the same effects as the first embodiment. Furthermore, the inspection system 10 of this embodiment can define the contents of the possession inspection suitable for each person to be inspected, and can perform the possession inspection with the defined contents. By customizing the contents of the possession inspection to suit each individual, it is possible to eliminate unnecessary inspections. As a result, the possession inspection becomes more efficient, and the waiting time for the inspection is shortened.

[0068] <Third embodiment> 11 shows an example of a functional block diagram of the inspection system 10 of the present embodiment. The inspection system 10 of the present embodiment differs from the inspection system 10 of the first embodiment in that it has an inspection unit 16.

[0069] The inspection unit 16 performs inspections on the subject of inspection other than the possession inspection based on the reflected wave signal of the electromagnetic wave having a wavelength of 30 micrometers or more and 1 meter or less (hereinafter, "possession inspection based on the reflected wave signal") described in the first and second embodiments. For example, the inspection unit 16 can perform a body temperature inspection to measure the body temperature of the subject of inspection, a possession inspection using a metal detector, a possession inspection using an odor detector, etc. These inspections can be realized by employing any technology.

[0070] The inspection unit 16 can output the inspection results via a predetermined output device (display, speaker, warning lamp, projection device, etc.). The output device may be installed, for example, at the inspection site, and may be configured to present predetermined information to the person being inspected or the manager who manages the inspection. Furthermore, the inspection unit 16 may change the output mode of the output device depending on the contents of the inspection results. There are various ways of outputting, and any means can be adopted in this embodiment.

[0071] The determination unit 12 determines which test to perform from among multiple types of tests for each test subject based on the individual specific information. The multiple types of tests include a possession check based on a signal of a reflected wave realized by the detection unit 13 and the electromagnetic wave transmission / reception unit 14, as well as the various tests described above realized by the inspection unit 16.

[0072] For example, as shown in Fig. 12, group-by-group information that defines the type of test to be performed for each group may be stored in the storage unit 15. Then, the determination unit 12 may determine the test to be performed for each test subject from among multiple types of tests based on the group-by-group information. The concept of groups and the means for identifying the group to which the test subject belongs are as described in the first embodiment.

[0073] 13, individual information that defines the type of test to be performed for each test subject may be stored in the storage unit 15. Then, the determination unit 12 may determine the test to be performed for each test subject from among multiple types of tests based on the individual information.

[0074] The determination unit 12 can output the determined content, i.e., information indicating the type of test to be performed, via a predetermined output device (display, speaker, lamp, projection device, etc.). The output device may be installed, for example, at the testing site, and may be configured to present the predetermined information to the test subject and the manager who manages the test.

[0075] Other configurations of the inspection system 10 of this embodiment are similar to those of the first and second embodiments.

[0076] As described above, the testing system 10 of this embodiment achieves the same effects as those of the first and second embodiments. Furthermore, the testing system 10 of this embodiment can perform a test suitable for each test subject. By customizing the test content to suit each individual, it is possible to eliminate unnecessary testing. As a result, the testing becomes more efficient and waiting time for testing is reduced.

[0077] <Modification> Modifications that can be applied to the first to third embodiments will be described below. These modifications also achieve the same effects as the first to third embodiments.

[0078] -First modified example- In FIG. 1, the individual specific information acquired by the individual specific information acquisition device 3 is transmitted to the server 1 via the detection device 2, but the individual specific information acquired by the individual specific information acquisition device 3 may be transmitted to the server 1 without passing through the detection device 2. For example, as shown in FIG. 15, the detection device 2 and the individual specific information acquisition device 3 may be connected in parallel to the server 1. Also, for example, an information collection device that collects information about the testing site may be installed at the testing site. Then, both the detection device 2 and the individual specific information acquisition device 3 may communicate with the server 1 via this information collection device.

[0079] -Second modified example- 14, the testing system 10 does not need to include the server 1. In this case, the detection device 2 and individual specific information acquisition device 3 installed at the testing site realize the acquisition unit 11, decision unit 12, detection unit 13, electromagnetic wave transmission / reception unit 14, and storage unit 15. Also, the testing unit 16 is realized by a local device installed at the testing site.

[0080] -Third variant- In the above embodiment, the individual specific information acquisition device 3 acquires individual specific information specific to the test subject from the test subject before the detection process is performed by the detection device 2. As a modified example, the individual specific information acquisition device 3 may acquire individual specific information after the detection device 2 transmits and receives electromagnetic waves and before the detection process is performed based on the reflected wave signal. For example, the test result may be determined offline.

[0081] -Fourth modified example- The abnormal state in the above embodiment is a state in which a person in a predetermined area is holding a preset detection object, and the detection unit 13 detects abnormal data (feature value of the detection object) that is undesirable to be included in the reflected wave signal from the reflected wave signal.

[0082] In this modified example, the detector 13 performs a detection process to detect an abnormal state (a state different from the state indicated by the normal data) from within the reflected wave signal, with reference to normal data that is preferably included.

[0083] -Fifth Variation- In the above embodiment, an object that is prohibited from being brought in is set as the detection object. Then, a state in which a person present in a predetermined area is carrying a preset detection object is detected as an abnormal state. In this modified example, an object that the user must have is set as the detection object. For example, a police badge or an object that a person participating in an event is required to carry is set as the detection object in this modified example. Then, in this modified example, a state in which a person present in a predetermined area does not carry a preset detection object is detected as an abnormal state. In this case, based on the attributes of the user in which the abnormal state is detected, it may be determined whether to perform a secondary inspection at that location or later. The attributes of the user may be those estimated from an image, such as gender and age, or may be others.

[0084] An object that is prohibited from being brought in may be set as detection object A, and an object that the user must have may be set as detection object B. In this case, the detection results will be divided into multiple cases, such as "a case where detection object A is detected and detection object B is not detected," "a case where detection object B is detected and detection object A is not detected," "a case where both detection objects A and B are detected," and "a case where neither detection object A nor B is detected." Which case is detected as an abnormal state is a design matter.

[0085] In this specification, "acquisition" includes at least one of the following: "the device itself goes to retrieve data stored in another device or storage medium (active acquisition)" based on user input or based on program instructions, such as receiving data by making a request or inquiry to another device, or accessing another device or storage medium and reading it, and "the device itself inputs data output from another device (passive acquisition)" based on user input or based on program instructions, such as receiving data that is distributed (or transmitted, push notification, etc.), and selecting and acquiring data from among the received data or information, and "editing data (converting it to text, rearranging data, extracting some data, changing the file format, etc.) to generate new data and acquiring the new data."
