Description

[Technical field]

[0001] This application claims priority to a Chinese patent application having application number 202010600568.2, filed on June 28, 2020, the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the technical field of security inspection, and in particular to an inspection method and system based on a millimeter wave security inspection device. [Background technology]

[0003] At present, most airport security inspections are still centered on methods such as "metal detector + manual inspection". Millimeter wave human body imaging technology is currently an advanced technology in the global security field, and is used in passenger security inspections at airports in the United States, the United Kingdom, the Netherlands, Australia, Japan and other countries. This device can effectively detect objects hidden in various parts of the human body under clothing without direct contact with the human body, especially non-metallic objects, and can obtain information such as the shape, size and location of the hidden objects from the image. In addition, the millimeter wave human body imaging device is harmless to the human body and has strong penetrating power, and its emission power is less than one thousandth of the electromagnetic radiation of a mobile phone, and can accurately identify the objects on the human body, effectively improving the objectivity, accuracy and validity of the inspection, reducing the labor intensity of security inspectors, and improving the efficiency of security inspection.

[0004] The operation method of the millimeter wave security inspection system also usually adopts a similar method to "metal door + manual inspection". Currently, the method of performing security inspection using products including millimeter wave security inspection devices such as Rodschwarz can be divided into the following four steps. In the first step (scanning step), the passenger is scanned by the security inspection device, and the security inspection device performs automatic dangerous object recognition (ATR), and then displays the character image and the location of the suspected object. In the second step (selection manual inspection station step), after the passenger is scanned by the security inspection device, the assigned manual inspection station number is directly displayed on the screen of the security inspection device, and the security inspection device operator manually selects and assigns the manual inspection station, and waits for the passenger to come to the selected manual inspection station position to undergo manual inspection. In the third step (image judgment step), when there is a demand for remote inspection images, the security inspection device transmits the scanned image and the information identified by the ATR together to the connected image judgment station, and the scanned image is manually inspected by the image inspection officer, and then the image judgment result (pass or warning) is submitted to the security inspection device. As the fourth step (manual inspection step), the security inspection device transmits the character image and suspect position information, as well as the image judgment result, to the manual inspection station previously selected by the operator, and the manual inspector performs manual inspection of the passenger based on the image and the position of the suspect.

[0005] However, the current security inspection method has the following problems: all business data is distributed and stored in each security inspection device and cannot be searched uniformly; after the security inspection device scans the passenger, the security inspection device operator needs to manually select and assign the manual inspection station; after the passenger flow rate increases, the manual inspectors and remote image inspectors cannot be dynamically increased; and when there are multiple security inspection devices (multiple security inspection channels) operating simultaneously, the manual inspection station and the image judgment station cannot be multiplexed. Therefore, an inspection method and apparatus based on a millimeter wave security inspection device to solve the above problems is needed. Summary of the Invention

[0039] At present, the operation mode of the millimeter wave security inspection system also generally adopts a similar mode to "metal door + manual inspection" (as shown in Figures 1 and 2), where the passenger completes the scan with the millimeter wave security inspection device, the security inspection device uses the automatic identification algorithm to detect dangerous objects, and then displays them directly on the screen of the security inspection device in the form of a scanned original map or character map (based on privacy considerations), and the passenger then comes to the stationary security inspector's position for manual inspection. If there is a need for privacy but still needs to see the original map, a stationary computer is placed in an environment isolated from the security inspection site and remotely connected to the device side to display the scanned image.

[0040] FIG. 3 shows a schematic diagram of an inspection system based on a millimeter wave security inspection device according to an embodiment of the present disclosure. The inspection system includes a background server system 310, a security inspection channel 320, a remote image judgment room 330, and a switch system 340.

It should be noted that the number of servers, security inspection devices, image judgment stations and switches is not limited to the number shown in the figure, and can be set by those skilled in the art according to actual needs. It should also be noted that the manual inspection station and the image judgment station do not need to exist in the inspection system, that is, the security inspection channel 320 may only include the security inspection device, and the remote image judgment room 330 does not need to exist.

[0041] Hereinafter, the inspection system will be described with reference to FIG. 4, taking one server and one security inspection device as an example. FIG. 4 shows a block diagram of an inspection system 400 based on a millimeter wave security inspection device according to an embodiment of the present disclosure. The inspection system 400 includes a security inspection device 410, a server 420, and a switch system 430. The security inspection device 410 obtains a scanned image by scanning an object (e.g., a person, an object, etc.), and obtains an ATR image judgment result by performing an automatic threat recognition (ATR) image judgment on the scanned image, and is arranged to upload the scanned image and the ATR image judgment result to the server 420. The server 420 is connected to the security inspection device 410 through the switch system 430, and is arranged to receive the scanned image and the ATR image judgment result from the security inspection device 410, and to perform a manual inspection task on the object and an image judgment task on the scanned image according to an operation mode, where the operation mode is arranged to instruct the inspection system 400 whether a manual inspection station and an image judgment station are arranged. The execution of the manual inspection task on the object and the execution of the image judgment task on the scanned image are performed simultaneously. The operation modes are classified into four types of operation modes, namely, a first operation mode in which neither a manual inspection station nor an image judgment station is arranged in the inspection system 400, a second operation mode in which the inspection system 400 is arranged with a manual inspection station but not with an image judgment station, a third operation mode in which the inspection system 400 is arranged with no manual inspection station but with an image judgment station, and a fourth operation mode in which the inspection system 400 is arranged with a manual inspection station and an image judgment station. Hereinafter, the operation of the server and the security inspection device will be described for each of the four different operation modes.

[0042] In one embodiment, the server 420 is further configured to specify not to perform manual inspection tasks on the object and image assessment tasks on the scanned image when the operational mode indicates that the manual inspection station and the image assessment station are not configured for the inspection system 400, i.e., when the inspection system 400 is in the first operational mode, and to store the scanned image and the ATR image assessment result, which may indicate the presence of a suspect in the scanned image or may indicate the absence of a suspect in the scanned image.

[0043] In one embodiment, the inspection system 400 further includes at least one manual inspection station 440 connected to the security inspection device 410 and the server 420 via the switch system 430, and the server 420 is further configured to: determine whether or not there is an available manual inspection station in the inspection system 400 when the operation mode indicates that a manual inspection station is configured but an image determination station is not configured in the inspection system 400, i.e., when the inspection system 400 is in a second operation mode, assign a manual inspection task, the scanned image, and the ATR image determination result for the object to one manual inspection station selected from the available manual inspection stations, send information of the selected manual inspection station to the security inspection device 410, and receive the manual inspection result from the manual inspection station 440, where the manual inspection result is generated by performing a manual inspection on the object using the scanned image and the ATR image determination result in response to receiving the assigned manual inspection task by the manual inspection station 440. The manual inspection result may instruct the subject to carry the suspected item, or may instruct the subject not to carry the suspected item. It should be noted that when the security inspection device 410 receives the information of the assigned manual inspection station, the operator of the security inspection device 410 can guide the subject to go to the assigned manual inspection station to wait for the manual inspection.

[0044] When the inspection system 400 is in the second operation mode, the server 420 is further configured to identify an available manual inspection station according to a predefined policy. The predefined policy includes at least one of: a manual inspection station designated by a user in a manual inspection station associated with the security inspection device 410; whether the gender of the subject is the same as the gender of the operator of the manual inspection station; whether the manual inspection station is within a predetermined number (e.g., one or two) of channels adjacent to the security inspection device; and whether the operator is idle. For example, an available manual inspection station must satisfy at least one of the following conditions: the manual inspection station is one of manual inspection stations #1, #2, #3 designated by a user in manual inspection stations #1-#10 associated with the security inspection device 410; the gender of the subject is the same as the gender of the operator of the manual inspection station; the manual inspection station is within a predetermined number (e.g., one or two) of channels adjacent to the security inspection device; and the operator is idle. It should be noted that there may be manual inspection stations that match more than one predefined policy, in which case one manual inspection station may be selected randomly, or the manual inspection station closest to the security inspection device 410 may be selected.It should be noted that there may be no manual inspection station that matches the predefined policy, i.e., there is no currently available manual inspection station, and in this case, the manual inspection station may be cyclically searched for until a manual inspection station that matches the predefined policy is found, or a manual inspection may be performed using the security inspection device 410. In such a case, when the inspection system 400 is in the second operation mode, the server 420 may further transmit a manual inspection request to the security inspection device 410 when it is determined that no manual inspection station is available in the inspection system 400, and when a positive confirmation response message is received from the security inspection device 410, the server 420 may perform a manual inspection. assigning a manual inspection task for the object to the security inspection device 410, where the positive acknowledgement message is generated by the security inspection device 410 in response to receiving a manual inspection request for itself from the server 420 when the security inspection device 410 is identified as currently available (e.g., an operator of the security inspection device allows the security inspection device to be used); and receiving manual inspection results from the security inspection device 410, where the manual inspection results are generated by performing a manual inspection on the object using the scanned image and the ATR image judgment results in response to receiving the assigned manual inspection task by the security inspection device 410. The security inspection device 410 is further configured to receive a manual inspection request from the server 420, determine whether the security inspection device 410 is currently available, and when the security inspection device 410 is currently available, send a positive acknowledgement message to the server 420, and when the security inspection device 410 is not currently available, send a negative acknowledgement message to the server 420, and in response to receiving an assigned manual inspection task, perform a manual inspection on the object based on the scanned image and the ATR image judgment result, and send the manual inspection result to the server 420.
