All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present invention, which is not described in detail herein.
Fig. 2 is a flowchart of a method for determining a user identity according to an embodiment of the present invention, and referring to fig. 2, the method includes:
step 201: and when detecting that the user enters the target area, acquiring a face image of the user.
In order to ensure the safety of non-commercial places such as residential districts, storehouses, confidential rooms and the like, the identity determination device can detect the user entering the target area, and the face image is the most easily acquired biological feature, so when the identity determination device detects that the user enters the target area, the identity determination device can acquire the face image of the user.
The target area may be an area where identification of a user entering a non-commercial place such as a residential district, a warehouse, a key house, or the like needs to be determined, and the target area is a main road for entering the place, for example, the target area may be an area where a gate of the residential district is located, which is not specifically limited in the embodiment of the present invention. In addition, the identity determining apparatus may be a security monitoring system, and the security monitoring system may include not only a function of acquiring an image, but also a display function, and the like, which is not specifically limited in the embodiment of the present invention.
It should be noted that, when detecting whether a user enters the target area, the detection may be performed through video monitoring, or may be performed through sensing devices such as sound, infrared rays, and temperature, which is not specifically limited in this embodiment of the present invention.
In addition, when the face image of the user is collected, the face image can be obtained by taking a picture, monitoring a video image in a video monitoring mode, and the like, and the embodiment of the invention also does not specifically limit the face image.
Step 202: and carrying out face recognition on the face image to obtain the face characteristics of the user.
Because the face features of each user are different, that is, the face features can uniquely identify the user identity, after the identity determination device collects the face image, the face recognition can be performed on the face image to obtain the face features of the user.
It should be noted that, the method for face recognition may refer to related technologies, and embodiments of the present invention are not described in detail here.
Step 203: and judging whether the stored feature database stores the facial features of the user, if so, executing the step 204, otherwise, executing the step 205.
Specifically, the identity determination apparatus may compare the facial features of the user with facial features stored in a feature database, determine that the facial features of the user are stored in the feature database if the facial features matched with the facial features of the user exist in the feature database, and otherwise determine that the facial features of the user are not stored in the feature database.
The operation of the identity determination device determining whether a face feature matching the face feature of the user exists in the feature database may be: if the feature database has a face feature that is the same as the face feature of the user, the identity determination apparatus may determine that a face feature that is matched with the face feature of the user exists in the feature database, and if the feature database does not have a face feature that is the same as the face feature of the user, determine that a face feature that is matched with the face feature of the user does not exist in the feature database. Or, the identity determining apparatus may determine a similarity between each of the face features in the feature database and the face feature of the user, determine whether a face feature greater than a similarity threshold exists in the feature database based on the determined similarity, determine that a face feature matching the face feature of the user exists in the feature database if the face feature greater than the similarity threshold exists in the feature database, and determine that a face feature matching the face feature of the user does not exist in the feature database if the face feature greater than the similarity threshold does not exist in the feature database.
It should be noted that the similarity threshold may be set in advance, for example, the similarity threshold may be 85%, 90%, and the like, and this is not specifically limited in the embodiment of the present invention.
For example, the face features stored in the feature database are face features 1, face features 2, face features 3, face features 4, and face features 5, respectively, the face feature of the user is face feature 4, and the identity determination apparatus may compare the face feature 4 of the user with the face features stored in the feature database, determine that the face feature 4 of the user is the same as the face feature 4 stored in the feature database, and further determine that the face feature of the user is stored in the feature database.
Furthermore, before the identity determination device judges whether the stored feature database stores the face features of the user, the identity determination device can also collect the face images of a plurality of legal users having the authority to access the target area to obtain a plurality of face images; respectively carrying out face recognition on the plurality of face images to obtain a plurality of face features; the plurality of facial features are stored in the feature database.
Although it is only necessary to determine that the stored feature database stores the facial features of the user when determining whether the stored feature database stores the facial features of the user, the feature database may also store other information such as the identity information and the access records of the user, and the identity of the user may be determined in an auxiliary manner through the information, so as to further improve the accuracy of determining the identity of the user. Therefore, when the face features are stored in the feature database, the identity determination device can directly store the face features of the legitimate users in the feature database, and can also acquire the identity information of the legitimate users, and store the face features and the identity information of the legitimate users in the corresponding relationship between the face features and the identity information included in the feature database.
Furthermore, when the identity determination device stores the plurality of face features in the feature database, the identity determination device may further obtain the identity information of the plurality of legitimate users, set initial values of the entry and exit records of the plurality of legitimate users, and store the plurality of face features, the identity information of the plurality of legitimate users, and the initial values of the entry and exit records of the plurality of legitimate users in the corresponding relationship among the face features, the identity information, and the entry and exit records included in the feature database.
It should be noted that, when the face features are stored in the feature database, other information of the legitimate users may also be obtained and stored in the feature database, which is not listed in the embodiment of the present invention.
In addition, the identity information is used to identify the identity of the legitimate user, and the identity information may be one or a combination of more of user name, identification number, address, work unit, and the like, which is not specifically limited in the embodiment of the present invention. Moreover, the access record may be one or a combination of information such as access time and access times, and when the identity determination device sets the initial access record values of the multiple legitimate users, the initial access record value may be set to be null, and of course, the identity determination device may also set the access record to be a default value, and the like.
For example, the identity determination apparatus obtains the face images of the legitimate users as a face image 1, a face image 2, a face image 3, a face image 4, and a face image 5, and performs face recognition on the face images of the legitimate users to obtain corresponding face features as a face feature 1, a face feature 2, a face feature 3, a face feature 4, and a face feature 5, and then the identity determination apparatus can also obtain the identity information of the legitimate users as an identity information 1, an identity information 2, an identity information 3, an identity information 4, and an identity information 5, and sets an entry and exit record initial value of the legitimate users as an entry and exit record 0, and stores the face features, the identity information of the legitimate users, and the entry and exit record initial value of the legitimate users in the feature database shown in the following table 1, including the face features, Identity information and access records.
TABLE 1
| Human face features | Identity information | Entry and exit records |
| Face feature 1 | Identity information 1 | Entry and exit record 0 |
| Face feature 2 | Identity information 2 | Entry and exit record 0 |
| Face features 3 | Identity information 3 | Entry and exit record 0 |
| Face feature 4 | Identity information 4 | Entry and exit record 0 |
| Face features 5 | Identity information 5 | Entry and exit record 0 |
It should be noted that, in the embodiment of the present invention, only the correspondence between the face features, the identity information and the entrance/exit records included in the feature database shown in table 1 is taken as an example for description, and table 1 does not limit the embodiment of the present invention.
Step 204: and determining that the user is a legal user, and displaying identity legal information, wherein the identity legal information is used for indicating that the user is an identity legal user.
The identity legal information may be text information, voice information, or a combination of text information and voice information, which is not specifically limited in this embodiment of the present invention.
When the identity legal information is character information, the identity determining device can directly display the identity legal information, and when the identity legal information is voice information or the voice information is combined with the character information, the identity determining device can convert the voice information into the character information and display the character information. Certainly, the identity determining apparatus may also play the identity valid information in a form of voice, that is, when the identity valid information is voice information, the voice information may be directly played, and when the identity valid information is text information or when the text information is combined with the voice information, the identity valid apparatus may convert the text information into voice information and play the voice information.
Further, after the identity determining apparatus displays the identity legal information, the identity determining apparatus may further obtain, based on the face features of the user, corresponding identity information from the correspondence between the face features and the identity information included in the feature database, and display the obtained identity information; or based on the face features of the user, acquiring corresponding access records from the corresponding relationship between the face features and the access records included in the feature database, and displaying the acquired access records; or based on the face features of the user, corresponding identity information and access records are obtained from the corresponding relation among the face features, the identity information and the access records included in the feature database, and the obtained identity information and the access records are displayed.
Furthermore, after the identity determining device displays the identity legal information, the access record of the user currently accessing the target area can be stored in the corresponding relationship between the face features and the access record included in the feature database, so as to update the corresponding relationship between the face features and the access record; or, the identity determination apparatus may further store an access record of the current access of the user to the target area in a corresponding relationship among the face features, the identity information, and the access record included in the feature database, so as to update the corresponding relationship among the face features, the identity information, and the access record.
It should be noted that, when the obtained information such as the identity information and the access record is displayed, the information may be displayed through the text information, the voice information, or the combination of the text information and the voice information, which is not specifically limited in this embodiment of the present invention.
Step 205: the user is determined as the identity pending user.
When the identity determination device determines the user as the user whose identity is to be determined, the identity determination device may further display the information whose identity is to be determined, where the information whose identity is to be determined is used to indicate that the user is the user whose identity is to be determined.
The identity undetermined information may be text information, voice information, or a combination of text information and voice information, which is not specifically limited in this embodiment of the present invention. In addition, the display or voice playing mode of the information to be determined of the identity is the same as the mode of the legal information of the identity, and the embodiment of the invention does not describe the information in detail.
It should be noted that the user whose identity is to be determined may be an illegal user or a legal user not stored in the feature database, and therefore, the identity determining apparatus may display the information whose identity is to be determined, so that the administrator may determine the identity of the user.
Further, when the identity determination device receives a valid user confirmation instruction based on the identity pending information, it may determine that the user is a valid user, and store the facial features of the user in the feature database.
The identity determination device can not only directly store the facial features of the user in the feature database, but also store the facial features of the user and the identity information of the user in a corresponding relationship between the facial features and the identity information included in the feature database when the identity information of the user is carried in the legal user confirmation instruction; or when the legal user confirmation instruction carries the identity information of the user, storing the face features of the user, the identity information of the user and the access records of the current access target area of the user in the corresponding relation among the face features, the identity information and the access records included in the feature database.
Optionally, when the identity determination device receives an illegal user confirmation instruction based on the identity undetermined information, the user can be determined to be an illegal user, and then the identity determination device can also store the face features of the user, so that when the user enters the target area next time, the user can be directly determined to be the illegal user, the identity of the user is prevented from being determined by an administrator, and the efficiency of user identity determination is further improved.
It should be noted that the valid user confirmation instruction is used to indicate that the user is a valid user, the illegal user confirmation instruction is used to indicate that the user is an illegal user, and both the valid user confirmation instruction and the illegal user confirmation instruction may be triggered by an administrator, which may be triggered by an appointed operation, which may be a click operation, a slide operation, a voice operation, and the like, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the invention, because the face image is the most easily acquired biological feature and the face feature obtained by face recognition of the face image can uniquely identify the identity of the user, the face image of the user entering and exiting the target area is collected and the face feature of the user is obtained by face recognition of the face image, so that the identity of the user is determined based on the face feature of the user without determining the identity of the user through an access card or a key and the like, the efficiency of determining the identity of the user is improved, the error rate of determining the identity of the user is reduced, and the safety of the place where the target area is located is ensured.
