The human face recognition is a biological recognition technology for carrying out identity recognition based on the facial feature information of people, and the basic process of the human face recognition is as follows: face detection, living body detection, face tracking, feature extraction, face comparison, result output and the like. Due to the advantages of non-contact property, naturalness, anti-counterfeiting property and the like, the face recognition technology is very suitable for service scenes needing high-frequency personnel identity verification, such as sign-in, welcome and the like.

With the development of technologies, sign-in systems based on face recognition are increasingly widely applied to real life. However, in the related technical solutions, one of the methods is to deploy the check-in system in a manner of combining the identification terminal and the display large screen, which is to ensure real-time display as much as possible, the identification terminal not only needs to have a video output interface (usually HDMI), but also needs to have higher image processing and rendering performance to complete the work of face detection, biopsy, feature extraction, feature comparison, welcome interface rendering, and the like, and the embedded identification device often cannot meet the higher requirement; meanwhile, the identification terminal and the large screen need to be connected through a video transmission cable (HDMI line), and the terminal needs to be ensured within a certain distance range of the large screen, so that the whole check-in system is not flexible to deploy, and the attractiveness of a check-in site and the check-in experience of a user are easily influenced; in addition, since one identification terminal can only be connected to one large-screen display device, check-in results of multiple objects on different devices cannot be displayed on the same display device.

In order to solve the above problem, an embodiment of the present disclosure provides a check-in system, which may include: the identification terminal is connected with the server through a communication mode of an http or https protocol, and the display terminal is connected with the server through a communication mode of an MQTT protocol. In the embodiment of the disclosure, a plurality of display terminals and a plurality of identification terminals may be provided, and each display terminal may subscribe a corresponding theme to the server according to a display requirement of the display terminal, for example, a staff face-brushing theme, a visitor face-brushing theme, or a VIP guest face-brushing theme, and the like. Therefore, after the identification terminal identifies the check-in object and transmits the identification result to the server, the server can send the identification result to the display terminal subscribed with the theme according to the theme corresponding to the identification result, for example, when the employee is identified, the identification result is sent to the display terminal subscribed with the theme of face brushing of the employee, when the visitor is identified, the identification result is sent to the display terminal subscribed with the theme of face brushing of the visitor, when the VIP guest is identified, the identification result is sent to the display terminal subscribed with the theme of face brushing of the VIP guest, and the like. The display terminal can display information to be displayed, such as the identity of the check-in object and the like according to the identification result sent by the server, for example, different types of check-in objects, such as employees, visitors and VIP guests, different check-in welcome pages and the like are displayed. By adopting the mode, the limitation of equipment such as a video transmission line and the like can be eliminated, the number and the installation positions of all terminals in the system can be flexibly deployed, the normal sign-in process is ensured, and meanwhile, the attractiveness of the sign-in site and the sign-in experience are greatly improved.

Fig. 1 shows a schematic structural diagram of a check-in system according to an embodiment of the present disclosure, and as shown in the figure, the check-in system includes more than one identification terminal 11, more than one display terminal 12, and a server 13 electrically connected to each identification terminal 11 and each display terminal 12, respectively. In response to the subscription request of the display terminal 12, the server 13 sends the identification result delivered by the identification terminal 11 to the display terminal 12 corresponding to the subscription request, wherein the identification result is obtained by identifying the check-in object through the identification terminal 11.

In the above-described disclosed embodiment, the specific number of the identification terminals 11 and the display terminals 12 can be flexibly determined according to the requirement. In a possible implementation manner, the number of the display terminals 12 may be set according to the number of categories to which check-in objects belong, for example, check-in objects of each category may be displayed through one display terminal 12, so as to implement classified display of the check-in objects. The category to which the check-in object belongs may be divided according to the identity of the check-in object, for example, when the check-in object belongs to one of companies (hereinafter, referred to as the company) to which the check-in system is currently applied, the category to which the check-in object belongs may be employees, when the check-in object does not belong to the company but visits the company by itself, the category to which the check-in object belongs may be guests, when the check-in object does not belong to the company and is invited to visit by the company, the category to which the check-in object belongs may be guests. In a possible implementation manner, the identification terminal 11 may be set according to the number of lanes of the check-in entry, for example, one identification terminal 11 may be set on each lane of the check-in entry to improve the efficiency of check-in identification.

In a possible implementation manner, the number of the identification terminals 11 may be multiple, the number of the display terminals 12 may be one, and the server 13 sends the identification result delivered by each identification terminal 11 to the display terminal 12 in response to the subscription request of the display terminal 12.

Based on the check-in system set according to the number, multi-device check-in can be achieved, namely recognition results of a plurality of recognition terminals can be gathered to the same display terminal to be displayed, and therefore the efficient multi-device check-in process is achieved.

In one possible implementation manner, the number of the identification terminals is multiple, and the number of the display terminals is multiple; and responding to the subscription request of the display terminal, and sending the identification result delivered by each identification terminal to the display terminal corresponding to the subscription request by the server.

When the number of the identification terminals and the number of the display terminals are multiple, the server may send the identification result of the identification terminal to the corresponding display terminal according to the subscription request of each identification terminal. It has been proposed in the above-mentioned disclosed embodiments that the subscription request may be divided according to the category of the check-in object, so that check-in situations of different check-in objects are displayed through different display terminals. In a possible implementation manner, the subscription request may also be divided according to time, for example, the display terminal may send the subscription request based on different check-in time periods to the server, so that when a plurality of identification terminals sequentially identify a plurality of identification results, the server may send the identification results to corresponding display terminals according to check-in times corresponding to the identification results for displaying, and thus, different display terminals may sequentially display check-in conditions of check-in objects according to a time sequence.

According to the disclosed embodiment, when a plurality of display terminals and identification terminals exist, different display terminals can be flexibly controlled to display different results through the division of subscription requests, and the flexibility of the sign-in system in displaying is greatly improved.

Through the system, information transmission between the identification terminal and the display terminal can be established through the server, video transmission cables are not needed for transmission, the flexibility of the deployment positions of all the terminals is improved, the number of the identification terminals and the number of the display terminals can be effectively increased, and the sign-in and display efficiency is improved.

The specific request content of the subscription request sent by the display terminal 12 can be flexibly determined according to the actual situation. In one possible implementation, the subscription request may include one or more of an employee subscription request, a first check-in object subscription request, and a second check-in object subscription request. The specific categories of the first check-in object and the second check-in object may be flexibly determined according to the categories of the check-in objects mentioned in the above disclosed embodiments, or may be expanded according to the categories of the check-in objects, for example, when the categories of the check-in objects are further classified, the subscription request may further include a third check-in object subscription request, a fourth check-in object subscription request, and the like. Thus, in one example, the first check-in object may be a guest object set forth in the above-described disclosed embodiment, and the second check-in object may be a guest object set forth in the above-described disclosed embodiment; in one example, the first check-in object may be a guest object set forth in the above-described disclosed embodiment, and the second check-in object may be a guest object set forth in the above-described disclosed embodiment; in one example, the first check-in object may be a general guest object proposed in the above-described disclosed embodiment, the second check-in object may be a VIP guest object or the like proposed in the above-described disclosed embodiment, and the third check-in object may be a guest object proposed in the above-described disclosed embodiment.

As can be seen from the above disclosed embodiments, the check-in objects may be divided into multiple categories, and different display terminals 12 may display the check-in objects of different categories, and if the identification results of all categories are sent to these display terminals 12, the display terminals 12 also need to self-filter which identification results are finally displayed, so that the display terminals 12 generate larger calculation consumption and resource requirements. In order to reduce the performance requirement on the display terminals 12, in a possible implementation manner, the subscription request of each display terminal 12, such as the employee subscription request, the visitor subscription request, the guest subscription request, and the like mentioned in the above disclosed embodiment, may be received to distinguish the identification results required by different display terminals 12, so that, after receiving the identification result sent by the identification terminal 11, the server 13 may send the identification result to the display terminal 12 subscribed to the category according to the category to which the identification result belongs. For example, a certain display terminal a is used for displaying display data of a staff specially, at this time, the display terminal a may send a staff subscription request to the server 13, when a certain staff signs at the identification terminal B, the identification terminal B transmits the identification result to the server 13, and the server 13 may determine that the sign-in object is a staff through the identification result, and send the identification result to the display terminal a based on the determination result, so that the display terminal a is convenient to display the display data of the staff.

Through one or more subscription requests including the employee subscription request, the first check-in object subscription request and the second check-in object subscription request, when a plurality of display terminals exist, data required to be displayed by the display terminals can be displayed in different display terminals according to display requirements, the display effect of the check-in system is improved, and the efficiency of managing the check-in system is also improved.

In a possible implementation manner, the server 13 may be electrically connected to each display terminal 12 through a Message Queue Telemetry Transport (MQTT) protocol, where in response to a subscription request transmitted by the display terminal 12 through the MQTT protocol, the server 13 transmits an identification result transmitted by the identification terminal 11 to the display terminal 12 corresponding to the subscription request through the MQTT protocol.

As can be seen from the foregoing disclosure, in one possible implementation manner, the display terminal 12 and the server 13 may be connected through communication, the display terminal 12 may send a subscription request to the server 13, and the server 13 may send an identification result corresponding to the subscription request to the display terminal 12, in order to enhance a connection stability between the display terminal 12 and the server 13 and improve connection efficiency between the display terminal 12 and the server 13, in one possible implementation manner, the connection between the server 13 and the display terminal 12 may be implemented through an MQTT protocol. The MQTT protocol is a message publishing and subscribing transport protocol that can provide real-time reliable service for connecting remote devices with limited bandwidth and less code.

Since the server 13 and the display terminal 12 may be connected by using the MQTT protocol, in a possible implementation manner, the display terminal 12 may send a subscription request to the server 13 by using the MQTT protocol, and after receiving the subscription request transmitted based on the MQTT protocol, the server 13 may send the identification result to the corresponding display terminal 12 by using the MQTT protocol when receiving the identification result corresponding to the subscription request.

The server is connected with each display terminal through the MQTT protocol, the characteristics of low cost and low bandwidth occupation of the MQTT protocol can be fully utilized, the performance requirement and the deployment difficulty of the whole check-in system are reduced, the time delay of display of the check-in system is reduced, and the real-time performance of display terminal display is improved.

In a possible implementation, the server 13 may be electrically connected to each identification terminal 11 through an http protocol or an https protocol; the server 13 may receive the identification result transmitted by each identification terminal 11 through an http protocol or an https protocol.

Generally, the identification result transmitted by the identification terminal 11 may include image data with a large data volume or other data with a large data volume, and since the HTTP interface is suitable for a scene with a large data volume and small concurrency, the identification terminal and the server are connected by an HTTP protocol or an HTTPs protocol, so that the transmission efficiency of the identification result in the check-in system can be further improved, and the efficiency and the stability of the check-in system can be improved.

In one possible implementation, identifying the terminal 11 may include: the interconnected camera is electrically connected to a first processor, which is electrically connected to the server 13. The camera acquires an image of the check-in object to trigger the first processor to identify the check-in object to obtain an identification result.

In the embodiment of the present disclosure, the first processor may be a processor having a face recognition function, and may recognize an image of a check-in object acquired by a camera to obtain a corresponding recognition result. The specific identification process of the first processor is not limited, and in one example, the first processor may obtain the identification result through face detection, living body detection, feature extraction and feature comparison in sequence, and the specific model structure of the first processor may be selected according to the actual situation. The first processor may be provided with a communication function in addition to the identification function, so as to enable connection with the server 13 via the http protocol or the https protocol. The specific content of the identification result may include an identity category of the check-in object, whether the check-in object is qualified for check-in, and the like.

Through the discernment terminal including interconnect's first camera and first treater, can reduce the functional requirement to discernment terminal, discernment terminal can need not to contain video output interfaces such as HDMI on the one hand, and on the other hand discernment terminal can only be to the discernment of the object of registering, and need not to carry out the work such as screening or generating display data to the object of registering, and when practical application, discernment terminal can realize through embedded equipment to greatly reduced the whole cost of the system of registering.

The camera of the identification terminal 11, the type and implementation thereof can be selected according to the actual situation. In one possible implementation, the camera may include an infrared binocular camera. The image of the object of registering through infrared camera collection when discerning, can be used for the live body to detect to further promote the degree of accuracy and the degree of safety of discernment, thereby promote the holistic degree of safety of the system of registering.

The recognition terminal 11 may be a face recognition machine or other terminal equipment with face recognition function.

Referring to fig. 2, the memory 111 is configured to store various types of data to support operations at the identification terminal 11. For a check-in scene of the check-in system of the present disclosure, a face image recognition library may be stored in the memory 111, so that a face image comparison is performed between an acquisition result acquired by the camera and the face image recognition library to obtain a recognition result. The memory 111 may be implemented by any type or combination of volatile or non-volatile memory devices, such as Static Random Access Memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disks.

The first power component 114 may include a power management system, one or more power sources, and other components associated with generating, managing, and distributing power for the identification terminal 11.

The face recognition component 115 is used for acquiring an acquisition result acquired by the camera, and extracting and storing a face image recognition library from the memory 111. Because the features to be recognized can be obtained according to the acquisition result, after the features stored in the face recognition library are extracted from the face image recognition library, the features to be recognized are compared with the features stored in the face image recognition library in a feature similarity manner to obtain a recognition result. The camera may be located in the sensor assembly 116.

The first processor 112 controls the above-mentioned components to operate, may obtain the recognition result in response to the check-in operation of the user, and controls the first communication component 113 to transmit the obtained recognition result to the server 13 through the http protocol or the https protocol.

In the embodiment of the present disclosure, the display data may be a welcome interface corresponding to the identity of the check-in object, such as a welcome interface including an image of the check-in object or a welcome animation including the identity of the check-in object.

The display may include a liquid crystal display, a projection display screen, or the like, and further, when the display is a liquid crystal display, a touch panel, or the like may be included, and if the screen includes a touch panel, the screen may be implemented as a touch screen to receive an input signal from a user. Because the check-in system provided by the embodiment of the present disclosure may include a plurality of display terminals 12, when the display terminals 12 are implemented, the same display may be used, and different displays may also be used. In one example, the check-in system may include a plurality of display terminals 12, wherein the display of one display terminal 12 may be a projected display large screen facing the overall check-in object, and the displays of the other display terminals 12 may be liquid crystal displays facing the direction of check-in objects of different identities, respectively. In one example, multiple displays may also be provided simultaneously within one display terminal 12.

Through the display terminal including interconnect's display and second treater, can be through the display data of second treater control display to realize different display terminal and show different display data, promote flexibility and the variety that the system of registering shows.

Since the display terminal 12 mainly realizes a display function, an existing electronic device having a display function can be directly used as a display terminal. In one possible implementation, the display terminal 12 may include: a mobile terminal or a display device with MQTT protocol function. In addition, the display terminal 12 may also include a projection device, a liquid crystal television, or the like.

The display equipment with the MQTT protocol function can be connected with the server through the MQTT protocol.

The display terminal comprising the mobile terminal or the display equipment with the MQTT protocol function and the like and formed by the existing electronic equipment can reduce the setting cost of the display terminal, thereby reducing the cost of the whole check-in system and improving the application range of the check-in system.

As shown, it includes: a second processor 121, a second communication component 122, a second power supply component 123, a display component 124 and a power amplifier component 125 comprising e.g. a speaker.

Referring to fig. 3, a second power supply component 123 provides power to the various components of the display terminal 12. Power components 114 may include a power management system, one or more power supplies, and other components associated with generating, managing, and distributing power for display terminal 12.

The second communication component 122 communicates with the server 13 via MQTT protocol, sends a subscription request to the server 13 via MQTT protocol, and receives identification data and the like sent by the server 13 via MQTT protocol.

The display component 124 is used for displaying display data, and may include a liquid crystal display, a projection display, etc., and further, it may cooperate with the power amplifier component 125 including a speaker, etc., to play data including images and sounds, such as videos or animations.

The second processor 125 controls the above components to operate, and may control the second communication component 122 to send a subscription request to the server 13 through the MQTT protocol, and after the second communication component 122 receives the identification result sent by the server 13, generate display data according to the identification result, send the display data to the display component 124 for display, and send the audio data to the power amplifier component 125 for playing when the display data further includes the audio data.
