In a possible implementation manner, the biometric identifier 30 may refer to fig. 2, which is a schematic diagram of the biometric identifier provided in an embodiment of the present application, and the biometric identifier 30 may include an infrared distance measuring sensor 31, a face recognition camera 32, an iris recognition camera 33, a screen 34, and a controller (installed inside, not shown), where the infrared distance measuring sensor 31, the face recognition camera, the iris recognition camera, and the screen are all electrically connected to the controller.

Fig. 3 is a flowchart of a method of biometric identification provided in an embodiment of the present application, and the biometric identifier 30 is applied to the biometric identification system shown in fig. 1, and the structure of the biometric identifier 30 can also be seen in fig. 2. The biometric identification method provided by the application can comprise the following steps:
step 301, when a human body is detected, the main control module controls a face recognition camera and an iris recognition camera to start scanning;
the master module referred to herein may be considered a master program or a master thread.
In practical application, the infrared distance measuring sensor of the biological characteristic recognizer can detect, detect and sense the human body positioned in front of the biological characteristic recognizer, and when the human body is detected, the distance between the human body and the biological characteristic recognizer can be further obtained and displayed on a screen of the biological characteristic recognizer, so that the station position of a user to be recognized can be adjusted when the distance is too far.
When a human body is detected, the infrared distance measuring sensor can send a detection result to the main control module, and the main control module controls the face recognition camera and the iris recognition camera to start scanning.
the face recognition module can be regarded as a face recognition program or a face recognition thread for performing face recognition authentication.
The face recognition camera sends the scanned image to the face recognition module, and the face recognition module carries out face feature recognition on the image. The algorithm of face feature recognition can be realized by those skilled in the art, and is not described herein again.
After the face recognition module acquires the face features, the face features can be further authenticated, and the authentication modes at least include the following two modes:
in the first mode, the biological feature recognizer locally stores a database, at this time, the face recognition module can directly traverse the local database, authenticate the scanned face features by using the traversed face features, and send a face authentication result to the main control module when the authentication is successful.
In a second mode, the biometric identifier locally stores a database, but needs to be sent to a server for authentication, at this time, the face recognition module sends a first face authentication request containing the scanned face features to the database server, the first face authentication request is used for triggering the database server to traverse the database, the scanned face features are authenticated by using the traversed face features, and when the authentication is successful, a face authentication success message is returned; and receiving the face authentication success message, judging that the face authentication is successful, and sending a face authentication result to the main control module.
During the authentication traversal, when a face feature is traversed, the traversed face feature needs to be compared with the face feature obtained by scanning, if the two face features are the same, the face feature obtained by scanning is judged to pass the authentication, otherwise, the next face feature in the database is continuously traversed, and the steps are sequentially circulated.
When a large number of mine personnel exist, the storage data in the database can be large, in order to further improve the authentication efficiency, the face recognition module judges whether the radio frequency card ID is received or not after the face features in the scanned image are obtained, if the radio frequency card ID is received, the radio frequency card ID identified by the radio frequency identifier is obtained, and the face recognition module can also realize the authentication of the face features through the following two modes:
in the third mode, the face features corresponding to the radio frequency card ID are searched in a local database, the scanned face features are authenticated according to the searched face features, and when the authentication is successful, a face authentication result is sent to the main control module;
a fourth mode, sending a second face authentication request containing the scanned face features and the radio frequency card ID to a database server, wherein the second face authentication request is used for triggering the database server to search the face features corresponding to the radio frequency card ID in a database, and returning a face authentication success message when the scanned face features are authenticated successfully according to the searched face features; and receiving the face authentication success message, judging that the face authentication is successful, and sending a face authentication result to the main control module.
Generally speaking, if the authentication fails, the face recognition module further obtains the face features in the image scanned again by the face recognition camera, and performs authentication on the face features obtained by scanning.
303, the iris recognition module acquires iris characteristics in the image scanned by the iris recognition camera, authenticates the iris characteristics, and sends an iris authentication result to the master control module after the iris recognition is successful;
the iris recognition module described here may be considered as an iris recognition program or an iris recognition thread that performs iris recognition authentication.
Similarly, the iris recognition camera sends the scanned image to the iris recognition module, and the iris recognition module performs iris feature recognition on the image. The iris feature recognition algorithm can be implemented by those skilled in the art, and will not be described herein.
After the iris recognition module obtains the iris features, the iris recognition module can further authenticate the iris features, and the authentication modes at least include the following two modes:
in the first mode, the biological characteristic recognizer locally stores a database, at the moment, the iris recognition module can directly traverse the local database, authenticate the scanned iris characteristics by using the traversed iris characteristics, and send an iris authentication result to the main control module when the authentication is successful.
In the second mode, the biological characteristic recognizer locally stores a database, but needs to be sent to a server for authentication, at the moment, the iris recognition module sends a first iris authentication request containing the scanned iris characteristics to the database server, the first iris authentication request is used for triggering the database server to traverse the database, the scanned iris characteristics are authenticated by using the traversed iris characteristics, and when the authentication is successful, an iris authentication success message is returned; and receiving the successful iris authentication message, judging that the iris authentication is successful, and sending an iris authentication result to the master control module.
During the authentication process, when one iris feature is traversed, the traversed iris feature needs to be compared with the iris feature obtained by scanning, if the two iris features are the same, the iris feature obtained by scanning is judged to pass the authentication, otherwise, the next iris feature in the database is continuously traversed, and the steps are sequentially circulated.
When a large number of mine personnel exist, the storage data in the database can be large, in order to further improve the authentication efficiency, the iris identification module judges whether the radio frequency card ID is received or not after acquiring the iris characteristics in the scanned image, if the radio frequency card ID is received, the radio frequency card ID identified by the radio frequency identifier is acquired, and the face identification module can also realize the authentication of the iris characteristics through the following two modes:
in the third mode, the iris characteristics corresponding to the radio frequency card ID are searched in a local database, the scanned iris characteristics are authenticated according to the searched iris characteristics, and when the authentication is successful, an iris authentication result is sent to the main control module;
a fourth mode, sending a second iris authentication request containing the scanned iris features and the radio frequency card ID to a database server, wherein the second iris authentication request is used for triggering the database server to search the iris features corresponding to the radio frequency card ID in a database, and returning an iris authentication success message when the scanned iris features are authenticated successfully according to the searched iris features; and receiving the successful iris authentication message, judging that the iris authentication is successful, and sending an iris authentication result to the master control module.
Similarly, if the authentication fails, the iris recognition module further acquires the iris features in the image scanned again by the iris recognition camera, and performs authentication on the iris features acquired by scanning.
In practical application, the face recognition module and the iris recognition module run in parallel.
And step 304, the master control module receives the face authentication result and the iris authentication result and judges that the authentication is passed.
In practical application, the main control module can judge that the authentication is passed as long as at least one of the face authentication result and the iris authentication result is received, and therefore the authentication speed is improved.
In a possible implementation manner, in step 301, after the infrared distance measuring sensor sends a result of detecting a human body to the main control module, the main control module starts timing to control the face recognition camera and the iris recognition camera to start scanning.
Correspondingly, in step 304, when the timing duration of the main control module does not reach the predetermined duration, if the main control module receives at least one of the face authentication result and the iris authentication result, it determines that the authentication is passed. The predetermined time period may be set according to actual conditions, and may be, for example, 3 seconds, 4 seconds, or the like.
Obviously, when the timing duration of the master control module reaches the preset duration and the face authentication result or the iris authentication result is still not received, the authentication is judged to be failed.
In summary, the biometric feature recognition method provided by the application combines the face feature recognition and the iris feature recognition, and when one of the face feature recognition and the iris feature recognition is recognized, the authentication is judged to be passed, so that the recognition efficiency and the accuracy are improved.
In addition, the radio frequency card ID of the radio frequency card carried by coal mine personnel is used as an index of the database, when the identification is carried out through the face feature or the iris feature in the database, the radio frequency card ID in the database is firstly inquired, the face feature and the iris feature corresponding to the radio frequency card ID in the database are obtained, and only the group of biological features in the database needs to be matched with the scanned biological features, so that the retrieval efficiency is greatly improved.
