Detailed Description
in order to make the technical problems, technical solutions and advantageous effects to be solved by the embodiments of the present application more clearly apparent, the present application is further described in detail below with reference to fig. 1 to 4 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless specifically defined otherwise.
referring to fig. 1, the present embodiment provides a face comparison pursuit system, which includes a face comparison terminal cluster 1 and an upper computer 2.
Referring to fig. 3, the face comparison terminal cluster 1 includes a plurality of face comparison terminals 11 deployed in the same designated pursuit area. The designated escape area can be a railway station, a bus station, a shopping mall, a street or other occasions where the escape personnel may appear; the designated pursuit area may also be a local location of an occasion, such as a square of a train station or a waiting lobby. In this embodiment, a plurality of face comparison terminals 11 are deployed in a square of the same train station and used as a cluster; the plurality of face comparison terminals 11 deployed in the waiting hall of the train station are used as another cluster.
referring to fig. 3, the face verification terminal 11 includes a camera 111, a first face verification controller 112, and a first input/output unit 113. The first face comparison controller 112 is configured to perform face comparison, and may run a face recognition comparison algorithm. In this embodiment, the first face matching controller 112 is hardware; in other embodiments, the first face alignment controller 112 is a virtual system.
The upper computer 2 runs face comparison upper computer service software. The upper computer 2 can receive the message from the face comparison terminal cluster 1, realize real-time communication with terminal equipment, and perform unified management on event interfaces of the face comparison terminal 11, specifically, perform unified management by upper computer service software for subsequent use.
referring to fig. 1, each face comparison terminal 11 may communicate with the upper computer 2. Each face comparison terminal 11 stores first information of the person who escapes received from the upper computer 2. That is, the upper computer 2 will issue the first information of the person who escapes to each face comparison terminal 11. Wherein the first escaper information is a face image. The first in-flight person information stored by at least one face comparison terminal 11 is different from the first in-flight person information stored by the other face comparison terminals 11.
The following method of the face comparison following system according to the present embodiment is described. Referring to fig. 2, the escape method of the present embodiment includes steps S1 to S3.
step S1, the camera 111 captures a live face image.
the camera 111 is a common camera, and is installed in the designated pursuit area, and is used for capturing a face image of a person appearing in the designated pursuit area.
Step S2, the first face comparison controller 112 compares the live face image with the stored first information of the person who escapes, so as to obtain a first comparison result.
the first face comparison controller 112 receives the live face image captured by the camera 111, compares the first escaped person information stored in the live face image first face comparison controller 112, and gives a comparison result in the form of a software event interface after the comparison is completed. In this embodiment, the first comparison result may be a comparison result of finding the first information of the person who is escaping, or may be a comparison result of completing the comparison between the live face image and the first information of the person who is escaping, where the former means that the first information of the person who is escaping is found in the designated escaping area, and the latter means that the first information of the person who is escaping is not found in the designated escaping area.
in step S3, the first input/output unit 113 transmits the first comparison result to the upper computer 2.
After the first face comparison controller 112 provides the first comparison result, the first input/output unit 113 transmits the first comparison result to the upper computer 2 for subsequent use.
the capacity of the face identification comparison algorithm is limited, that is, the number of faces that can be identified by the face identification comparison algorithm is limited, which limits the capacity of the face comparison terminal. However, the number of people who escape is very large, the information of people who escape stored in the face comparison terminal needs to be changed regularly, which may cause the chance of missing people who escape before recognition for a certain time.
As can be seen from the above, in this embodiment, a plurality of face comparison terminals 11 deployed in the same designated pursuit area are used as a cluster, and the first information of the escaped person stored in at least one face comparison terminal 11 is different from the first information of the escaped person stored in the other face comparison terminals 11. Each face comparison terminal 11 in the cluster is communicated with the upper computer 2, and can report comparison results to the upper computer 2 after face comparison is completed. Therefore, a plurality of faces are compared with the terminal 11 to form a whole, so that more information of the person escaping from the flight can be recorded into the whole, and the capacity of the information of the person escaping from the flight which can be recorded is enlarged. The embodiment can use the camera which is installed in the appointed escape area before, can save the transformation cost and has good compatibility.
In other embodiments, the first information of the person who escapes from any one of the face comparison terminals 11 is different from the first information of the person who escapes from the remaining face comparison terminals 11. That is, the information of the first person in flight stored in each face comparison terminal 11 is different, for example: the first person-in-flight information stored in the first face comparison terminal 11 is a person-in-flight, the first person-in-flight information stored in the second face comparison terminal 11 is a person-in-flight, the third person-in-flight information stored in the third face comparison terminal 11 is a person-in-flight, and so on. In this way, the capacity of the information of the escaped personnel which can be recorded can be enlarged to the maximum extent.
Referring to fig. 1, the face comparison pursuit system of the present embodiment further includes a multi-thread face comparison terminal 3. Referring to fig. 4, the multi-thread face collation terminal 3 includes a plurality of second face collation controllers 31. Compared with the face comparison terminal cluster 1 of the embodiment, the multi-thread face comparison terminal 3 does not include a camera.
The second face comparison controllers 31 may store second escaping person information, specifically, second escaping person information received from the upper computer 2. The second escaper information represents the escaper information stored in the second face comparison controller 31, and the first escaper information represents the escaper information stored in the first face comparison controller 112. The second escaping people information stored in any one of the second face comparison controllers 31 is different from the second escaping people information stored in the other second face comparison controllers 31. That is, the first escaped person information stored by each second face comparison controller 31 is different from each other.
the multithread face comparison terminal 3 can receive the face image to be compared, specifically, the face image to be compared is received from the upper computer 2. The face image to be compared is received by the multi-thread face comparison terminal 3 from the outside; the live face image is captured by the face comparison terminal cluster 1 through the camera 111. Referring to fig. 4, of course, the multithreaded face comparison terminal 3 may also receive the face image to be compared through the built-in interface unit 32; the interface unit 32 can communicate with each second face comparison controller 31; the interface unit 32 has a plurality of interfaces, and each interface corresponds to one second face comparison controller 31; when a certain interface is connected to the external device, the communication between the corresponding second face comparison controller 31 and the external device can be realized.
The plurality of second face comparison controllers 31 may compare the face image to be compared with the stored second information of the escaped person to obtain a second comparison result. The multi-thread face comparison terminal 3 communicates with the upper computer 2, so that the second comparison result is transmitted to the upper computer 2.
according to the above, the multithread face comparison terminal 3 integrates the plurality of second face comparison controllers 31, and the first information of the person who escapes is stored in each second face comparison controller 31 is different, so that more information of the person who escapes is allowed to be entered, and the volume of the information of the person who escapes that can be entered can be enlarged. Because the multithread face comparison terminal 3 does not comprise a camera, the multithread face comparison terminal can be made into a portable terminal, and the face image to be compared can be intercepted from the video stream of the existing video recording system and then input into the multithread face comparison terminal 3 for comparison, so that the multithread face comparison terminal is convenient to use.
Compared with a large machine room, the human face comparison terminal cluster 1 and the multithreading human face comparison terminal 3 of the embodiment save more energy and require smaller bandwidth.
Referring to fig. 1, the face comparison pursuit system of the present embodiment further includes a network cloud event service subsystem 4, a network cloud alarm service subsystem 5, a network cloud decision distribution subsystem 6, an escaper face comparison pursuit management subsystem 7, a local database 8, an escaper data synchronization subsystem 9, and an external database 10.
in the embodiment, the network cloud event service subsystem 4, the network cloud alarm service subsystem 5, the network cloud decision distribution subsystem 6, the person-in-flight face comparison and pursuit management subsystem 7 and the person-in-flight data synchronization subsystem 9 are virtual systems running on the cloud. In other embodiments, the network cloud event service subsystem 4, the network cloud alarm service subsystem 5, the network cloud decision distribution subsystem 6, the on-flight person face comparison pursuit management subsystem 7, and the on-flight person data synchronization subsystem 9 are separate servers.
the upper computer 2 can receive messages from the face comparison terminal cluster 1 and the multi-thread face comparison terminal 3. The upper computer 2 runs upper computer service software. The upper computer service software is an intermediate service system which bridges the terminal with other software systems. The upper computer service software also realizes real-time communication with the terminal equipment, performs unified management on the event interface of the terminal and provides a function interface for other software systems to call.
The network cloud event service subsystem 4 is used for completing event information transmission between the upper computer 2 and each subsystem, and is a software information interface system.
The network cloud alarm service subsystem 5 may communicate with the network cloud event service subsystem 4 to enable the notification to be issued based on the first comparison result. After the network cloud alarm service subsystem 5 snapshottes the escaped person, for example, first escaped person information or second escaped person information is found, a series of alarm processing is performed; specifically, the network cloud alarm service subsystem 5 issues the successfully compared live face images or face images to be compared with the WEB (WEB) and pushes the APP and links other software systems to notify events; more specifically, the network cloud alarm service subsystem 5 communicates with the network issuing subsystem 51 and the short message notification subsystem 52 to issue and send short message notifications on a network.
the network cloud decision distribution subsystem 6 can communicate with the network cloud event service subsystem 5, the external database 8 and the escaped person data synchronization subsystem 9 to define and distribute decisions. The network cloud decision distribution subsystem 6 is a system integrating policy definition and distribution, and is used for setting a series of processing mechanisms and decision schemes through man-machine conversation according to the processing mechanism mode, controlling each subsystem by using different processing mechanisms and decision schemes when different events occur.
The face comparison and follow-up management subsystem 7 of the escaped person can communicate with the network cloud event service subsystem 5 and the local database 8. The face comparison and follow-up management subsystem 7 of the escaper is a main man-machine conversation system and is communicated with the network cloud event service subsystem 5 and the local database 8, so that the functions of entering the escaper, setting parameters of each subsystem, managing and checking the state of terminal equipment, calling the terminal equipment, checking data, issuing bulletins, processing data and data reports and the like can be realized.
The local database 8 is used for storing local data and can be communicated with the upper computer 2 and the person-escaping data synchronization subsystem 9.
The external database 10 is used to input data to the local database 8. The external database 10 may be a flight crew database or a third party database.
The escape personnel data synchronization subsystem 9 is used for completing data synchronization. The on-flight data synchronization subsystem 9 synchronizes the on-flight data from the third-party database to the publicly released on-flight data or calls a network interface provided by the third party, synchronizes the on-flight data to the local database 8, and synchronizes the on-flight data belonging to the local database 8 in an external database 10 such as a cloud database to the local database 8 according to the decision of the network cloud decision distribution subsystem 6.
the working principle of the face comparison pursuit system of the embodiment is explained. Basic information of the person escaping from the building is input through a face comparison and follow-up management subsystem 7 of the person escaping from the building or is synchronized with a third-party in-flight information base through a data synchronization subsystem 9 of the person escaping from the building, and the basic information of the person escaping from the building is loaded into a local database 8; setting an indication data distribution condition of the network cloud decision distribution subsystem 6; setting the distribution frequency of upper computer service software of the upper computer 2; setting a distribution mode of upper computer service software of the upper computer 2; and setting an alarm strategy of the network cloud alarm service subsystem 5. When the escaped person data synchronization subsystem 9 acquires data conditions needing synchronization through the network cloud decision distribution subsystem 6, data of the escaped persons belonging to the local is acquired from an external database 10 such as a total database of all the escaped persons and synchronized to the local database 8. The upper computer 2 obtains a strategy required by local operation through the network cloud decision distribution subsystem 6, and communicates with the face comparison terminal cluster 1 or the multi-thread face comparison terminal 3 to execute the strategy. After the face comparison terminal cluster 1 or the multi-thread face comparison terminal 3 completes comparison, the comparison result is reported to the upper computer 2, and the upper computer service software running on the upper computer 2: communicating with the local database 8 to store the comparison result; and the system is communicated with the network cloud event service subsystem 4 to issue an alarm through the network cloud alarm service subsystem 5.
According to the above, the embodiment can realize the localization of the pursuit comparison, so that the response of the system is more timely, and the bandwidth required by the system is smaller.
the short message notification subsystem 52 sends a notification to the short message receiving mobile phone according to a preset decision after the host computer 2 receives the result of successful comparison of the escaped people. The short message notification subsystem 52 includes a short message sending terminal or a short message sending interface provided by the internet. The short message notification subsystem 52 is provided with a preset decision scheme. Therefore, even if the face comparison pursuit system is deployed in a local area network, the result can be fed back to the superior system.
the face comparison pursuit system of the present embodiment further includes a network cloud face comparison subsystem 53. The network cloud face comparison subsystem 53 can communicate with the network cloud alarm service subsystem 5 to manually compare the successfully compared live face image with the first information of the escaped person. After the terminal device, such as the face comparison terminal cluster 1 or the multi-thread face comparison terminal 3, completes the comparison event, the network cloud face comparison subsystem 53 establishes comparison image information of the image of the person of the on-site face image determined by the terminal device as a comparison success with the image-text information related to the person who escapes, provides a user session interface, and the worker performs manual comparison at the manual comparison image terminal 54, such as the APP of the smart phone, gives a manual comparison result, and issues related processing flow information and operation strategies. Thus, the accuracy of pursuit can be ensured.
The manual comparison image terminal 54 receives the comparison image information sent by the network cloud face comparison subsystem 53, and the manager holding the manual comparison image terminal 54 performs manual secondary identification, and issues a pursuit emergency notification through the network cloud alarm service subsystem 5 by using the manual comparison image terminal 54.
