Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Because the existing metal security inspection door only depends on a single alarm standard, for the above situation, when the security inspection is performed on the personnel to be passed, false alarm exists for the personnel with the carrying authority, and alarm omission exists for the personnel without the passing authority. Therefore, the security inspection precision in the related technology is low, and the occurrence frequency of false alarm and false alarm is high. In order to solve the above technical problem, an embodiment of the present invention provides a security inspection system.

Next, a security inspection system provided in an embodiment of the present invention is described first.

Fig. 1 is a schematic structural diagram of a security inspection system according to an embodiment of the present invention, and as shown in fig. 1, the security inspection system may include the following devices:

the image acquisition device 110 is used for acquiring a face image of a person to be passed and sending the face image to the data processing device;

the data processing device 120 is used for receiving the face image and determining the target passing attribute of the person based on the face image; determining a target security inspection strategy corresponding to the target traffic attribute based on the corresponding relation between the traffic attribute and the security inspection strategy, and sending the target security inspection strategy to the metal security inspection door;

and the metal security inspection door 130 is used for receiving the target security inspection strategy, performing metal detection on the personnel based on the target security inspection strategy, and outputting a security inspection result.

The image capturing device 110 and the data processing device 120 may be communicatively connected, and each of the image capturing device 110 and the data processing device 120 is an independent electronic device for performing the function thereof, for example, the image capturing device 110 may be a camera, a monitoring probe, or the like, and the data processing device 120 may be a notebook computer, a desktop computer, or the like; the image capturing device 110 may be a device formed by a lens and an imaging module in a camera, and the data processing device 120 may be a microprocessor added to the camera to perform the above functions. This is all reasonable. Based on this, the embodiment of the present invention does not limit the specific types of the image capturing device 110 and the data processing device 120.

For the person to pass through the metal security inspection door, when the image acquisition device 110 captures the person, the image acquisition device can acquire the face image of the person and send the acquired face image to the data processing device 120.

The image capturing device 110 may be installed at any position where a human face image of a person to be visited can be captured, for example, the image capturing device may be installed above the metal security door 130, or installed in front of the metal security door 130, or, when the number of the image capturing devices 110 is plural, the image capturing devices 110 may be installed at different positions, for example, above the metal security door 130 and on the left and right side walls of the metal security door, which is reasonable.

Optionally, after the person to be passed carries out the shooting range of the image acquisition device 110, the image acquisition device 110 may track the person, that is, in the traveling process of the person, continuously capture the picture of the person, and shoot the face image of the pedestrian until the distance between the person and the metal security inspection door 130 is less than the preset distance, so as to acquire the face image of the person. Further, the image capturing device 110 can send the captured face image to the data processing device 120.

The preset distance may be determined according to relevant parameters of the image capturing device 110 used in practical applications, which is not limited in the embodiments of the present invention.

Optionally, after the person to be passed carries out the shooting range of the image acquisition device 110, the image acquisition device 110 may track the person, that is, continuously capture the picture of the person in the advancing process of the person, detect the shooting quality of the face image of the person in the captured picture, and determine whether the quality of the face image reaches the preset quality standard. In this way, when the quality of the detected face image of the person reaches the preset quality standard, the image acquisition device 110 may shoot the face image of the person according to the preset shooting frequency until the number of the shot face images reaches the preset shooting number. Furthermore, the image capturing device 110 may select a face image with the best shooting quality from the preset number of face images captured as the final face image of the person, and send the selected face image with the best shooting quality to the data processing device 120.

The preset quality standard, the preset shooting frequency and the preset shooting quantity may be determined according to relevant parameters of the image acquisition device 110 and a required detection accuracy rate, which are used in practical applications.

Optionally, the shooting direction of the image acquisition device 110 may be aligned to a queue formed by people waiting to pass through the metal security inspection door 130, and further, the image acquisition device 110 may shoot a first person in the queue to obtain a face image of the person, and send the face image of the person to the data processing device 120. When the security check of the person is completed and the security check result corresponding to the person is obtained, the person behind the person in the queue becomes the first person in the queue, and the image acquisition device 110 may photograph the new first person to obtain the face image of the new person and send the face image of the new person to the data processing device 120. Thus, as the metal security inspection door 130 continuously performs metal detection on the previous person to obtain a security inspection result, the first person in the queue is continuously updated, and the image acquisition device 110 can continuously acquire the updated face image of the first person and send the acquired face image to the data processing device 120 until all the persons to pass in the queue are completely subjected to security inspection.

Of course, the image acquisition device 110 may also acquire the face image of the person to be passed through by other methods, which is not limited in the embodiment of the present invention.

Further, when the data processing device 120 receives the face image of the pedestrian to be passed sent by the image acquisition device 110, the target passing attribute of the pedestrian can be determined based on the face image, and further, the data processing device 120 can determine the target security check policy corresponding to the target passing attribute based on the correspondence between the passing attribute and the security check policy, and send the determined target security check policy to the metal security check door 130.

The data processing device 120 may determine the target passing attribute of the person based on the face image in a variety of ways, which is not limited in this embodiment of the present invention. For the sake of line clarity, the manner in which the data processing device 120 determines the target passing attribute of the person based on the face image will be exemplified later.

The essence of the target passing attribute of the person to be passed determined by the data processing device 120 is to determine whether the person to be passed has the right to pass through the metal security inspection door 130 and the right to carry metal objects. Based on this, optionally, in a specific implementation manner, the correspondence between the passage attribute and the security check policy may include the following contents:

the passing attribute is as follows: unregistered persons, blacklisted persons, and abnormal pedestrian traffickers, corresponding to the security inspection policy: whether people are detected to carry metal objects or not is judged, and an alarm is given; wherein, the blacklist personnel are: people who have been registered but do not have access rights; the abnormal pedestrian communication personnel are as follows: in the white list of people, the passing time is not matched with the current time and/or the passing place is not matched with the position of the metal security inspection door 130; the white list people are: registered personnel with passage authority;

the passing attribute is as follows: normally the person is in the traffic and cannot carry metal items, corresponding to the security check strategy: when detecting that the personnel carries the metal object, alarming, otherwise, not alarming; wherein, normal passerby is: in the white list of people, the passing time is matched with the current time, and the passing place is matched with the position of the metal security inspection door 130;

Specifically, the method comprises the following steps:

when the passing attribute of the person to be passed is unregistered, that is, in the various person lists of the factory or the enterprise, the person to be passed does not exist. For example, unregistered personnel may be a factory employee that came to the factory for the first time, a salesperson that came to the first time, and so on. Obviously, the person to be passed does not have the right to pass through the metal security door 130, that is, the person to be passed cannot pass through the metal security door 130 whether or not the person to be passed carries a metal object. Therefore, when the passage attribute of the person to be passed is an unregistered person, the security policy determined by the data processing apparatus 130 is: and if the person is detected to carry the metal object, the alarm is given.

When the passing attribute of the person to be passed is a blacklisted person, that is, in the various person lists of the factory or the enterprise, although the person to be passed exists, the person does not have the authority to pass through the metal security inspection door 130, that is, the person to be passed cannot pass through the metal security inspection door 130 whether the person to be passed carries a metal object or not. Such as those who have left their job, those who have come multiple times, etc. Obviously, the person to be passed cannot pass through the metal security door 130 regardless of whether the person to be passed carries a metal article. Therefore, when the passage attribute of the person to be passed is the blacklisted person, the security policy determined by the data processing apparatus 120 is: and if the person is detected to carry the metal object, the alarm is given.

When the passing attribute of the person to be passed is an abnormal passing person, namely the person to be passed is a registered person with passing authority, but the passing time of the person to be passed is not matched with the current time; or, although the person to be passed through is a registered person with a passing right, the passing place of the person to be passed through is not matched with the position where the metal security inspection door 130 is located, or, although the person to be passed through is a registered person with a passing right, the passing time of the person to be passed through is not matched with the current time, and the passing place of the person to be passed through is not matched with the position where the metal security inspection door 130 is located. That is, the person to be passed is present in the various person lists of the plant or the enterprise, but it is not normal that the person to be passed wants to pass through the metal security gate 130 at the current time. For example, the employees of the home factory who appear in the abnormal passage time period, the employees of the home factory who appear in the non-self passage area, and the like. Obviously, the person to be passed cannot pass through the metal security door 130 regardless of whether the person to be passed carries a metal article. Therefore, when the passage attribute of the person to be passed is an abnormal person, the security policy determined by the data processing device 130 is: and if the person is detected to carry the metal object, the alarm is given.

When the passing attribute of the person to be passed is normal passing person and can not carry the metal object, that is, the person to be passed is a registered person with passing authority, the passing time of the person to be passed is matched with the current time, and the passing place of the person to be passed is also matched with the position of the metal security inspection door 130. That is, the person to be passed exists in the list of various persons in the factory or the enterprise, and in the current time period, the person to be passed wants to pass through the metal security inspection door 130 normally, but the work position of the person to be passed determines that the person to be passed cannot carry the metal object, that is, the person to be passed has the right to pass through the metal security inspection door 130, but does not have the right to carry the metal object. For example, normally traveling plant equipment operators of the plant, normally traveling plant pipeline operators of the plant, and the like. Obviously, when the person to be passed does not carry metal objects, the person to be passed can pass through the metal security door 130, and otherwise, the person to be passed cannot pass through the metal security door. Therefore, when the passage attribute of the person to be passed is normal passing person and the metal object cannot be carried, the security policy determined by the data processing device 130 is: and when detecting that the personnel carry the metal object, alarming, otherwise, not alarming.

When the passing attribute of the person to be passed is normal passing person and can carry the metal object, that is, the person to be passed is a registered person with passing authority, the passing time of the person to be passed is matched with the current time, and the passing place of the person to be passed is also matched with the position of the metal security inspection door 130. That is, the person to be passed exists in the list of various persons in the factory or enterprise, and in the current time period, the person to be passed wants to pass through the metal security inspection door 130 normally, and further, the work position of the person to be passed determines that the person to be passed can carry metal objects, that is, the person to be passed has the right to pass through the metal security inspection door 130 and has the right to carry metal objects. For example, a manager of the plant, a maintenance person of the plant, and the like. Obviously, the person to be passed can pass through the metal security door 130 regardless of whether the person to be passed carries a metal article. Therefore, when the passage attribute of the person to be passed is a normal person and can carry a metal object, the security policy determined by the data processing device 130 is: and if the person is detected to carry the metal object, the alarm is not given.

In addition, optionally, the correspondence between the passing attribute and the security check policy may further include other contents, for example, the type, size, weight, and the like of the metal object carried by the person may be defined, that is, after it is determined that the person to be passed has the right to carry the metal object, the type, size, weight, and/or the like of the metal object carried by the person may be further determined, so as to further determine whether the person to be passed has the right to pass through the metal security check door 130.

Therefore, the alarm standard of the metal security inspection door can be further refined, so that the security inspection fineness is further improved, and the occurrence frequency of false alarm and missed alarm is reduced.

Thus, after receiving the target security inspection policy, the metal security inspection door 130 may detect whether the person to be passed carries a metal object by using the metal detection module based on the target security inspection policy, so as to obtain a detection result, that is, obtain a security inspection result, and further output the security inspection result.

When the security check result is an alarm, the metal security check door 130 outputs the security check result, i.e., outputs an alarm signal.

Optionally, the manner of outputting the alarm signal by the metal security inspection door 130 may be: and outputting sound, namely, a sound output device can be included in the metal security door. Therefore, when the metal detection module is used for detecting whether the to-be-passed person carries a metal object or not and the result of the security check is an alarm, the metal security check door 130 can alarm through the sound output device.

Specifically, the sound output device may be a device capable of producing sound, such as an alarm bell, an intelligent audio device, or a voice player. Therefore, the security personnel in charge of the metal security inspection door can easily know that the personnel to be passed does not have the passing authority, and need to identify the identity and other information of the personnel so as to adopt the next processing mode.

Optionally, the manner of outputting the alarm signal by the metal security inspection door 130 may be: and outputting characters, namely, a character output device can be included in the metal security inspection door. Therefore, when the metal detection module is used for detecting whether the to-be-passed person carries a metal object or not and the result of the security check is an alarm, the metal security check door 130 can alarm through the character output device.

Specifically, the text output device may be a liquid crystal display, an LED (Light Emitting Diode) screen, or other devices capable of displaying text.

Optionally, the manner of outputting the alarm signal by the metal security inspection door 130 may be: and signal lamp output, namely, signal lamps can be included in the metal security inspection door. Therefore, when the metal detection module is used for detecting whether the to-be-passed person carries a metal object or not and the result of the security check is an alarm, the metal security check door 130 can display the designated color through the signal lamp to alarm.

The setting mode can be implemented to set which color the signal lamp displays to indicate that the metal security inspection door 130 sends out the alarm signal.

Optionally, the metal security door 130 may output an alarm signal in at least two modes including the sound output, the text output, and the signal light output.

Next, a mode in which the data processing device 120 executes the above steps will be described as an example.

Optionally, as shown in fig. 2, in a specific implementation manner, the manner in which the data processing apparatus 120 determines the target passage attribute of the person based on the face image may include the following steps:

s201: searching a target face image matched with the face image in each preset reference face image; when not found, executing step S202, and when found, executing step S203;

wherein, the reference face image is a face image of a registered person;

after obtaining the face image of the person to be passed sent by the image acquisition device 110, the data processing device 120 may compare the face image with preset face images to determine whether a target face image matching the face image of the person to be passed exists in the preset face images.

The data processing apparatus 120 may execute the step S201 in various ways, and the embodiment of the present invention is not limited in particular.

Optionally, the data processing device 120 may respectively model the face image of the person to be passed and each preset face image to obtain a feature vector of each face image, further respectively calculate an included angle cosine value between the feature vector of the face image of the person to be passed and each preset face image, and further determine whether the calculated maximum included angle cosine value is greater than a preset matching threshold. If the number of the reference face images is larger than the preset number, determining that a target face image matched with the face image is found in each preset reference face image, and determining the preset face image corresponding to the maximum included angle cosine value as the target face image matched with the face image of the person to pass; otherwise, determining that the target face image matched with the face image is not found in each preset reference face image.

In this way, when the target face image matching the face image is found in the preset reference face images, the data processing apparatus 120 may continue to perform the subsequent step S202, otherwise, the data processing apparatus 120 may continue to perform the subsequent step S203.

S202: determining the passing attribute of the person as follows: unregistered personnel;

s203: determining the type of a person list to which the person belongs based on the target face image, if the person belongs to a blacklist, executing step S204, and if the person belongs to a whitelist, executing step S205;

wherein the types include: a black list and a white list;

in step S201, when the data processing apparatus 120 does not find the target face image matching the face image of the person to be passed in the preset reference face images, since the reference face image is the face image of the registered person, it may be determined that the person to be passed is not registered, and further, it is determined that the passing attribute of the person is: no person was registered.

Correspondingly, when the data processing device 120 finds the target face image matched with the face image of the person to pass through from the preset reference face images, since the reference face image is the face image of the registered person, it can be determined that the person to pass through is registered, and the found target face image is the face image of the person to pass through collected in advance. In this way, based on the searched target face image, the type of the list of people to which the person to pass belongs may be further determined, so as to determine whether the person has the right to pass through the metal security inspection door 130.

The data processing apparatus 120 may execute the step S203 in various ways, and the embodiment of the present invention is not limited in particular.

Optionally, the blacklist includes a preset face image of a blacklist person, and the white list includes a preset face image of a white list person, the data processing apparatus 120 may search in the blacklist whether the determined target face image is included, and when the target face image is found, it is determined that the list of persons to which the person to be passed belongs is the blacklist, otherwise, it is determined that the list of persons to which the person to be passed belongs is the white list; the data processing device 120 may also search for whether the determined target face image is included in a white list, and when the target face image is found, determine that the list of people to which the person to pass belongs is a white list, otherwise, determine that the list of people to which the person to pass belongs is a black list; the data processing device 120 may further search whether the determined target face image is included in the black list and the white list at the same time, determine that the person list to which the person to pass belongs is the black list when the target face image is searched in the black list, and determine that the person list to which the person to pass belongs is the white list when the target face image is searched in the white list.

Optionally, each preset reference person image may be associated with a person identifier corresponding to the reference face image, the blacklist includes a preset person identifier of the blacklist person, and the whitelist includes a preset person identifier of the whitelist person. Thus, after the target face image is determined, the data processing device can simultaneously determine the target person identifier corresponding to the target face image. Furthermore, the data processing apparatus 120 may search for whether the determined target person identifier is included in a blacklist, and when the target person identifier is found, determine that the list of persons to which the person to pass belongs is the blacklist, otherwise, determine that the list of persons to which the person to pass belongs is the white list; the data processing apparatus 120 may also search for whether the determined target person identifier is included in a white list, and when the target person identifier is found, determine that the list of persons to which the person to pass belongs is a white list, otherwise, determine that the list of persons to which the person to pass belongs is a black list; the data processing apparatus 120 may further search whether the determined target person identifier is included in the blacklist and the white list at the same time, determine that the person list to which the person to be passed belongs is the white list when the target person identifier is found in the blacklist, and determine that the person list to which the person to be passed belongs is the black list when the target person identifier is found in the white list.

In this way, when the list of people to which the person to pass belongs is determined to be the blacklist, the data processing apparatus 120 may continue to perform the subsequent step S204, otherwise, the data processing apparatus 120 may continue to perform the subsequent step S205.

S204: determining the target passing attribute of the person as follows: blacklist people;

s205: determining personnel post information associated with the personnel recorded in the white list, and judging whether the personnel are in a normal passing state and have metal article carrying permission or not at present based on the personnel post information; if the person is not in the normal passing state, executing step S206; if the person is in the normal passing state and has the metal article carrying right, executing the step S207; if the person is in the normal passing state and the person does not have the carrying right of the metal object, executing the step S208;

in step S203, when the data processing apparatus 120 determines that the person list to which the person to pass belongs is the white list, the data processing apparatus 120 may further determine the staff position information associated with the person recorded in the white list, and determine whether the person is currently in a normal passing state and has a metal article carrying authority based on the staff position information.

Wherein, the information of the position of a person can comprise the position, the passing time and the passing place of the person. The position of the person can represent the specific work content of the person, and further represents whether the person has the authority of carrying metal objects; the transit time of the person may represent a time when the person has the right to pass through the metal security door 130, for example, the person has the right to pass through the metal security door 130 during the normal working time of the person, and therefore, the normal working time of the person may be taken as the transit time of the person; the passing place of the person can represent a place where the person has access authority, for example, the person can enter a work place area of the person, and then the work place of the person can be used as the passing place of the person; in addition, according to the position of the person, the passage place of the person may be only one area, for example, a certain workshop, or may be a passage place range formed by one or more areas, for example, a factory area formed by a plurality of workshops; this is all reasonable. Of course, other information may also be included, and the embodiments of the present invention are not particularly limited thereto.

Optionally, the white list may record the personnel position information of each person in the white list. Obviously, after the target face image is found in the white list or the target person identifier determined based on the target face image is found, the person post information associated with the target face image or the target person identifier in the white list is the person post information of the person to be cleared, and then the data processing device 120 may determine whether the person is currently in a normal passing state and whether the person has a metal article carrying permission based on the person post information of the person to be cleared.

Optionally, the white list may be associated with a person post information record table, and after a face image or a person identifier in the white list is determined, the person post information corresponding to the face image or the person identifier may be determined in the person post information record table. Obviously, after the target face image is found in the white list or the target person identifier determined based on the target face image is found, the data processing device 120 may determine, based on the target face image or the target person identifier, the person post information corresponding to the target face image or the target person identifier in the person post information record, where the determined person post information is the person post information of the person to be passed, and further, the data processing device 120 may determine, based on the person post information of the person to be passed, whether the person is currently in a normal passing state and whether the person has a metal article carrying permission.

Specifically, the data processing device 120 may determine whether the person is a normal person passing through by determining whether the current time matches the passing time of the person to pass through and whether the passing location of the person to pass through matches the position of the metal security door 130. For example, it is determined whether the current time is the passing time of the person to be passed and whether the position of the metal security door 130 is within the passing place range of the person to be passed.

When the current time is matched with the passing time of the person to be passed and the passing place of the person to be passed is matched with the position of the metal security inspection door 130, the person to be passed can be determined to be a normal person to be passed, and otherwise, the person to be passed can be determined to be an abnormal person to be passed. For example, when the current time is the passing time of the person to be passed and the position of the metal security door 130 is within the passing place range of the person to be passed.

Furthermore, after the person to be passed is judged to be a normal person to pass, whether the person to be passed has the metal article carrying authority can be further judged based on the position of the person to pass, when the person to be passed has the metal article carrying authority, the person to be passed can be judged to carry the metal article, and if the person to be passed does not carry the metal article, the person to be passed can not be judged to carry the metal article.

In this way, when the person to be passed is determined to be an abnormal person, the data processing apparatus 120 may continue to perform the following step S206; when the person to be passed is determined to be a normal person and has the metal article carrying authority, the data processing device 120 may continue to perform the following step S207; after determining that the person to be passed is a normal person and does not have the metal article carrying authority, the data processing apparatus 120 may continue to perform the following step S208.

S206: determining the target passing attribute of the person as follows: an abnormal pedestrian;

s207: determining the target passing attribute of the person as follows: people are normally on the go and can carry metal objects;

s208: determining the target passing attribute of the person as follows: people are normally in the open and cannot carry metal objects.

It can be understood that when a person to be passed approaches the metal security door 130, the person to be passed may turn his head to look at a direction other than the direction of the metal security door 130, thereby reducing the occurrence frequency of false alarms and missed alarms in order to better collect the face image of the person to be passed. Optionally, in a specific implementation manner, the manner in which the image acquisition device 110 acquires the face image of the person to be visited and sends the face image to the data processing device may include the following steps:

collecting a plurality of face images of the person to be passed, and sending the plurality of face images to the data processing device 120;

optionally, the security inspection system provided in the embodiment of the present invention may include a plurality of image capturing devices 110. Each image acquisition device can acquire the face image of the person to be passed, so as to obtain a plurality of face images of the person to be passed, and further, the image acquisition device 110 can send the acquired plurality of images to the data processing device 120.

Accordingly, in this embodiment, as shown in fig. 3, the step S201 executed by the data processing apparatus 120 to search for the target face image matching with the face image in each preset reference face image may include the following steps:

S201A: calculating the image quality score of each received face image, and determining the face image with the highest image quality score obtained by calculation as a face image to be matched;

S201B: and searching a target face image matched with the face image to be matched in each preset reference face image.

In this specific implementation manner, after receiving the face images of the multiple persons to be passed, the data processing device 120 may model the face image of each person to be passed, so as to calculate an image quality score of the face image of the person to be passed. Furthermore, after calculating the image quality score of the face image of each person to be passed, the data processing device 120 may determine the face image of the person to be passed with the highest calculated image quality score as the face image to be matched. In this way, the data processing apparatus 120 searches for a target face image matched with the face image to be matched in each preset reference face image.

The data processing apparatus 120 may then continue to perform the following steps 202-208.

In order to ensure the accuracy of the determined target traffic attributes of the persons to be traveled, the frequency of occurrence of false alarms and missed alarms is further reduced, corresponding to the above-described specific implementation of fig. 3. Optionally, in a specific implementation manner, in step S202, it is determined that the passing attribute of the person is: before the person is not registered, the method for determining the target passing attribute of the person by the data processing device 120 based on the face image may further include the following steps:

step 1: traversing each alternative face image in the plurality of face images, searching a target face image matched with the alternative face image in each preset reference face image when traversing each alternative face image, and if the target face image is searched, determining the type of a person list to which the person belongs based on the target face image; otherwise, traversing the next alternative face image;

step 2: when a target face image matched with each candidate face image is not found in each preset reference face image aiming at each candidate face image, executing to determine the passing attribute of the person as follows: unregistered personnel;

When the target face image matched with the face image to be matched is not found in the preset reference face images, the data processing device 120 may determine the face images of the received persons to be passed, except the face image to be matched, as the alternative face images. Further, the data processing device 120 may traverse each candidate face image.

Specifically, when traversing each candidate face image, the data processing device 120 may search a target face image matched with the candidate face image in each preset reference face image, and if the target face image is found, the data processing device 120 may continue to execute the step S203, and determine the type of the person list to which the person belongs based on the target face image; otherwise, the data processing device 120 may traverse the next candidate face image.

In this way, when traversing each candidate face image, and finding the target face image matched with the candidate face image from the reference face images that are not preset by the data processing device 120, it can be stated that there is no target face image matched with the face image of any person to be passed in the received face images of a plurality of persons to be passed in each preset reference face image, that is, the face image of the person to be passed cannot find the face image of the preset person to be passed in each preset reference face image. At this time, the data processing apparatus 120 may continue to execute the following step S202, and determine that the passage attribute of the person is: no person was registered.

It can be understood that, due to the installation angle of the image capturing device 110, the person to be passed intentionally blocking the face, and the like, there may be a case where the image capturing device 110 does not capture the face image of the person to be passed.

Obviously, when the image capturing device 110 does not capture the face image of the person to be passed through, the metal security door 130 cannot obtain the target security policy sent by the data processing device 120. However, in this case, when the person to be passed who has not acquired the face image by the image acquisition device 110 passes through the security door 130, the security door 130 may still detect whether the person to be passed carries a metal object.

That is to say, the image capturing device 110 does not capture the face image of the person to be passed through, so that the metal security inspection door 130 can still detect whether the person passes through the metal security inspection door 130 under the condition that the metal security inspection door 130 does not receive the target security inspection policy sent by the data processing device 120.

Based on this, in order to ensure normal production and personal safety of the staff, when the target security inspection strategy sent by the data processing device 120 is not received and a person is detected to pass through, the metal security inspection door 130 sends an alarm signal regardless of whether the person carries a metal object.

Optionally, as shown in fig. 4, in a specific implementation manner, the security inspection system provided in the embodiment of the present invention may further include: a gate 140, wherein the gate 140 is in a gate-off state by default;

in this specific implementation manner, the metal security inspection door 130 may be further configured to: when the security check result is that no alarm is given, a brake opening signal is sent to the brake;

accordingly, gate 140 may be used to: and receiving the switching-off signal, executing the switching-off action, and executing the switching-off action when the switching-off signal meets the preset switching-off condition.

It can be understood that, when the security inspection result of the metal security door 130 is no alarm, that is, the metal security door does not send an alarm signal, it indicates that the person to be communicated can pass through the metal security door 130, and further, indicates that the person to be communicated can pass through the gate 140.

Thus, when the security inspection result is no alarm, the metal security inspection door 130 can transmit a brake opening signal to the brake 140. Thus, after receiving the opening signal, the gate 140 performs an opening operation, and the current closing state is changed to the opening state, so that the person to pass enters the target area to be entered through the gate 140. Then, when the gate 140 in the open state meets the predetermined close condition, the gate can be closed, and the default gate closing state is recovered.

In order to ensure that each person to be passed through the gate 140 is a person having the authority to pass through the metal security inspection door 130, and to prevent a person who is not determined whether the person having the authority to pass through the metal security inspection door 130 passes through the gate 130 after the person having the authority to pass through the metal security inspection door 130, which may cause a missing inspection and cause a safety hazard, after each person having the authority to pass through the metal security inspection door 130 passes through the gate 130, the gate 130 needs to be restored from the open state to the closed state until an open signal is received again, and an open operation is performed.

That is, after the gate 140 performs the gate opening operation, it is necessary to determine whether the predetermined closing condition is met in time, so that the gate closing operation is performed when the predetermined closing condition is met.

Therefore, in order to perform the gate closing operation when the predetermined closing condition is met, optionally, at least one target sidewall of the gate 140 may be provided with an obstacle detection component, where the target sidewall is the sidewall where the gate 140 is located. Thus, after the gate 140 performs the opening operation, the obstacle detecting component may detect whether a predetermined closing condition is met, and notify the gate 140 to perform the closing operation when the predetermined closing condition is detected to be met. It is reasonable that the obstacle detecting unit is activated after the gate 140 performs the opening operation, or is always activated.

The obstacle detecting unit may be any device capable of detecting whether the gate 140 meets a predetermined shutdown condition, and notifying the gate 140 to perform a shutdown operation when the detection result indicates that the predetermined shutdown condition is met. The embodiment of the present invention is not particularly limited. In addition, the novel embodiment of the invention also does not limit the specific installation position of the obstacle detecting component on the target side wall.

For example, the fault detection component may be a radar. Specifically, a radar may be installed on one side wall where the gate 140 is located, and the radar may transmit a wireless signal to a position opposite to the other side wall, and when the wireless signal reaches the other side wall, the wireless signal may be reflected by the other side wall and received by the radar. Obviously, when the gate 140 is in the gate-off state, the time for the radar to transmit a wireless signal and receive the reflected wireless signal is fixed. Thus, when the gate 140 is in the open state, the person to pass through may form an obstacle between the two side walls while passing through the gate 140, and the wireless signal transmitted by the radar may be reflected by the pedestrian without reaching the other side wall, so that the time for the radar to transmit the wireless signal and receive the reflected wireless signal may be shortened. Then, when the radar monitors the time required for transmitting the wireless signal and receiving the reflected wireless signal to return to the gate closing state of the gate 140, it can be determined that the person to pass has passed through the gate 140, and further, the gate 140 is notified to perform the gate closing action, and the gate opening state returns to the gate closing state.

As another example, the obstacle detecting component may be an infrared signal generator and an infrared signal receiver. Specifically, an infrared signal generator may be installed on one side wall where the gate 140 is located, and an infrared signal receiver may be installed at a position opposite to the infrared signal generator on the other side wall. Thus, the infrared signal generator can emit an infrared signal, and the infrared signal receiver can receive the infrared signal after a certain propagation time. Obviously, when the gate 140 is in the gate-off state, the infrared signal receiver can receive the infrared signal at regular intervals according to the transmitting frequency of the infrared signal generator and the distance between the two gates. Thus, when the gate 140 is in the open state, the person to pass through the gate 140 may form an obstacle between the two sidewalls, and the infrared signal receiver cannot receive the infrared signal emitted from the infrared signal generator. Then, when the infrared signal receiver can receive the infrared signal once again at regular intervals, it can be determined that the person to pass has passed through the gate 140, and further, the gate 140 can be notified to perform a gate closing action, so as to recover from the gate opening state to the gate closing state.

Optionally, as shown in fig. 5, in a specific implementation manner, the security inspection system provided in the embodiment of the present invention may further include: a background management device 150;

in this specific implementation manner, the data processing device 120 may be further configured to send the determined target passing attribute and the target security inspection policy of the person to be passed to the background management device 150;

the metal security inspection door 130 may be further configured to send a security inspection result to the background management device 150;

the background management device 150 may be configured to receive the target traffic attribute, the target security policy, and the security result; generating and storing security check information record items of personnel;

wherein, the security check information record item includes: the current time, the target passing attribute, the target security inspection strategy and the security inspection result.

In this specific implementation, a security check information entry for each person to be passed is recorded in the background management device. Therefore, when an accident or other needs occur, the personnel information which is required to enter a certain target area through a metal security inspection door at a certain place at a certain time or within a certain time period can be determined by looking up the recorded security inspection information record items of each person to be passed, and the person to be passed involved in the accident or other needs can be reviewed and positioned.

It can be understood that the background management device 150, the image capturing device 110 and the data processing device 120 may be communicatively connected, and may be independent electronic devices respectively used for completing the functions of the background management device and the image capturing device; or may be independent devices installed in the same electronic device for performing the above functions; the image capturing device 110 may be an independent electronic device for performing the above functions, and the background management device 150 and the data processing device 120 may be independent devices installed in the same electronic device for performing the above functions, respectively; the data processing device 120 may be an independent electronic device for performing the above functions, and the background management device 150 and the image capturing device 110 may be independent devices installed in the same electronic device for performing the above functions, respectively; the background management device 150 may be an independent electronic device for performing the above functions, and the image capturing device 110 and the data processing device 120 may be independent devices installed in the same electronic device for performing the above functions, respectively. This is all reasonable.

Further, the image capturing device 110 may be an image capturing device in a video monitoring system, so that after the personnel to be passed involved in the unexpected situation or other needs are reviewed and located, the video pictures shot by the video monitoring system in the time period including the current time can be called according to the current time recorded in the called security check information record item, and further, the unexpected situation can be known in more detail, or more information required by other needs can be obtained.
