Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a face recognition access control management method according to a first embodiment of the present invention, which is applicable to a case of managing face template information stored in a local database in a lightweight access control terminal. The method can be executed by a face recognition access control management device, the device can be realized in a software and/or hardware mode, and can be configured in electronic equipment, for example, the electronic equipment can be equipment with communication and computing capabilities such as a background server. As shown in fig. 1, the method specifically includes:
Wherein, the candidate is any one of all people with access control authority. Only the face information collected by the person with the access control authority when passing through the access control terminal can be successfully matched with the face template information which is input in advance. Illustratively, all people with access control authority are predetermined, face template information of each person is collected, wherein the face template information at least comprises a face template picture and also can comprise personnel identity information and the like, the face template information is pre-recorded into an access control terminal, if the face template information needing recording exceeds the upper limit of the storage capacity of the access control terminal, the face template information is stored in a central server, and only part of the face template information is stored in the access control terminal.
The preset period refers to a period for updating face template information stored in the access control terminal. If the face template information is stored in the local database of the access control terminal, when corresponding personnel pass through the access control terminal, the face pictures collected by the access control terminal only need to be compared locally to obtain a comparison result, and the comparison result does not need to be sent to a central server side for comparison, so that the efficiency of the personnel with the face template information stored in the local database passing through the access control terminal is higher than that of the personnel stored in the central database. Although all people have access control authority, the number of times and frequency that each person passes through the access control are different, so if the face template information of the person with lower activity passing through the access control is stored in the access control terminal, the waste of storage resources of the access control terminal can be caused. The liveness of the people can be influenced by various external factors and can change frequently, so that the face template information stored in the entrance guard terminal needs to be updated regularly to ensure that the face template information stored in the entrance guard terminal is the people with high liveness. For example, the preset period is one day or one week, and the update time of the end of the preset period is determined according to the start time of the preset period, for example, 24 points per day is determined as the update time of the end of the preset period corresponding to the case that the preset period is one day.
All the acquisition time included in the acquisition time set is the time recorded when the entrance guard terminal acquires the face information of the candidate when the candidate passes through the entrance guard. Specifically, in a preset period, when the entrance guard terminal collects the picture of the passerby, the picture is compared with the face template information of all the personnel, and if the comparison is successful, the identity information of the personnel and the collecting time T of the face picture are determined i Mapping and storing the acquisition time and the face template information of the personnel, acquiring the acquisition time of each face template information correlation mapping in all the personnel when the update time of the end of the preset period is reached, and determining the acquisition time set [ T ] of each candidate personnel 1 ，T 2 ，...，T i ，...，T n ]And the collection time set represents all time points when the candidate person passes through the entrance guard in a preset period.
And 102, determining the attenuation activity of the target acquisition time according to the time distance difference between the target acquisition time and the update time in the acquisition time set.
And the target acquisition time is any acquisition time in the acquisition time set. The attenuation activity of the target acquisition time represents the activity of the candidate person, which is increased to the candidate person by the candidate person appearing in the access control terminal in the target acquisition time.
Because the probability that the candidate person appears again is lower as the distance from the updating time is longer, the activity degree of the candidate person appearing at the target acquisition time is attenuated according to the time distance difference between the target acquisition time and the updating time of the candidate person so as to distinguish the increased value of the activity degree of the person represented by the acquisition time different from the updating time distance difference, and the accuracy of determining the activity degree of the candidate person according to the acquisition time is improved. For example, if the update time is 24 points, the first target acquisition time of the first candidate is 8 points, and the second target acquisition time of the second candidate is 16 points, the attenuation activity of the first target acquisition time of the first candidate is less than the attenuation activity of the second target acquisition time of the second candidate. When the collection time in the collection time set is more, the difference of the occurrence of the personnel at different collection times can be reflected according to the attenuation activity.
Specifically, a mapping relation between the time distance difference and the attenuation activity is established in advance, the attenuation activity associated with different time distance differences is determined according to the mapping relation and is used as the attenuation activity of the target acquisition time, and the attenuation activity of each acquisition time in the acquisition time set is determined according to the mapping relation.
In a specific example, the decay time T is preset a Every lapse of time T a Attenuating the activity value of the person appearing before by an attenuation coefficient alpha, wherein 0<α<1. And determining the attenuation activity of the target acquisition time according to the attenuation time, the attenuation coefficient and the time distance difference.
In one possible embodiment, step 102 includes:
determining the attenuation activity of the target acquisition time according to the following formula:
wherein S represents the attenuation activity of the target acquisition time, P represents a preset basic activity value, alpha represents a preset attenuation coefficient, and T represents now Representing update time, T representing target acquisition time, T a Indicating a preset decay time.
The decay time is set according to a preset period, wherein the decay time is less than the preset period, which means that the activity needs to be attenuated every time a decay time elapses within the preset period. The basic activity value represents the increased basic activity degree of the candidate acquired by the entrance guard terminal each time. The attenuation coefficient characterizes the degree of attenuation, 0< α <1.
Illustratively, if the target acquisition time is 8 points, the update time is 24 points, the decay time is set to one hour, the decay coefficient is set to 0.5, the basic activity is set to 10, and the decay activity of the target acquisition time is
And respectively determining the attenuation activity of each acquisition time in the acquisition time set according to the formula.
And 103, determining the activity of the acquisition time set according to the attenuation activity of each acquisition time in the acquisition time set, and taking the activity as the periodic activity of the candidate personnel.
And respectively determining the attenuation activity of each acquisition time in the acquisition time set, and taking the sum of the activity of all the acquisition times in the acquisition time set as the activity of the acquisition time set and the period activity of candidate personnel.
Illustratively, the collection of acquisition times for the candidate is [ T ] 1 ，T 2 ，...，T i ，...，T n ]Then the determined attenuation activity is [ S ] 1 ，S 2 ，...，S i ，...，S n ]Wherein S is i Is T i The decay activity of (2) is the activity of the collection time set
And step 104, determining target personnel according to the periodic activity of all the personnel, and storing the face template information of the target personnel in a local database of the access control terminal.
And determining the periodic activity of each person according to the steps, performing descending order on all the persons according to the periodic activity, taking a preset number of target persons with the activity order being in the front according to the upper limit of the storage capacity of the access control terminal, and storing the face template information of the preset number of target persons in a local database of the access control terminal. Illustratively, target face template information of the first X target persons with the highest activity values is taken, face template information which is not in the target face template information on the entrance guard terminal is deleted, and meanwhile, the target face template information which is not in the entrance guard terminal is issued to the entrance guard terminal from the central server.
According to the embodiment of the invention, the activity of the personnel is determined according to the time of the personnel entering and exiting the entrance guard by combining the time attenuation factor, and then the personnel information stored on the entrance guard terminal and the personnel information stored by the central service terminal are adjusted according to the activity of the personnel, so that the efficiency of the personnel passing through the entrance guard terminal is improved, the requirement on the local database capacity of the entrance guard terminal is reduced, and the lightweight design of the human face entrance guard terminal is ensured.
Example two
Fig. 2 is a flowchart of a face recognition access control management method in a second embodiment of the present invention, which is further optimized based on the above embodiment, and is preset in an abnormal time period within a preset period, as shown in fig. 2, the method specifically includes:
The information storage position identifier comprises an entrance guard terminal and a central server and is used for representing the position where the face template information of the candidate person is stored when the candidate person passes through the entrance guard terminal at the acquisition time, and if the face template information is stored in a local database of the entrance guard terminal, the information storage position identifier of the candidate person is the entrance guard terminal; and if the face template information is stored in a central server of the central server, identifying the information storage position of the candidate personnel as the central server.
Specifically, the information storage location identifier may be determined according to an address when face information of the candidate face is successfully matched.
In one possible embodiment, determining the information storage location identity of the candidate person carried by the collection time set includes:
determining a matching result of face acquisition information of the associated candidate persons in the acquisition time set;
if the matching result is that the face matching in the initial database is successful, determining that the information storage position mark is an entrance guard terminal;
and if the matching result is that the face matching is successful in the central database, determining that the information storage position is identified as the central server.
When the entrance guard terminal collects the face information of the candidate personnel, the face information is firstly matched with the face template information in the local database, and if the local similarity value with the maximum local matching similarity is larger than or equal to the preset similarity threshold, the matching result is determined to be that the face matching in the initial database is successful. And if the local similarity value with the maximum local matching similarity is smaller than a preset similarity threshold, sending the face information to a central server to be matched with the face template information in the central database, and if the central similarity value with the maximum central matching similarity is larger than or equal to the preset similarity threshold, determining that the matching result is that the face matching in the central database is successful. And if the central similarity value with the maximum central matching similarity is smaller than the preset similarity threshold, determining that the matching result is unsuccessful, and the person does not have the access right item, so that the access does not perform door opening treatment. Illustratively, the face information includes a face feature value, the face template information includes a face template feature value, and the face feature value is matched with the face template feature value when matching.
And determining a corresponding information storage position identifier according to the matching result of the face acquisition information of the candidate person so as to mark the storage position of the face template information of the candidate person.
In a feasible embodiment, the central database stores face template information of all persons with access control authority; and the initial database determines according to the image quality of the face template images in the face template information of all the personnel.
The face template information of all people with access control authority is stored in the central server, the initial database refers to the initial state in the local database of the access control terminal, and the initial database is determined according to the picture quality of the face template pictures.
Specifically, face template information of all people is determined in advance, picture quality scores representing picture quality are determined according to the definition of face template pictures, face angles and the proportion of faces in the face template pictures, all people are arranged in a descending order according to the picture quality scores, a preset number of target people with the picture quality scores in front are taken according to the storage capacity limit of the access control terminal, and the face template information of the preset number of target people is stored in a local database of the access control terminal, so that an initial database is obtained. Illustratively, the entrance guard storage capacity is X, and the face template information of the first X persons with the highest picture quality scores is issued to the front-end entrance guard terminal.
The abnormal time indicates a special time period for the entrance guard to enter or exit, specifically, the abnormal time period includes a forward abnormal time period and a reverse abnormal time period, where the forward abnormal time period indicates that the person appearing in the time period has a high probability, that is, the probability of the next occurrence is high, for example, the forward abnormal time period may be set to an on-duty peak time period, and the probability of the next occurrence of the person appearing in the time period is high, and the person has a high probability of the next occurrence. The reverse direction abnormality period indicates that the person who appears in the period has a chance, that is, the probability of the next occurrence is low, for example, the reverse direction abnormality period may be set in the night period, for example, from 22 o 'clock to 6 o' clock on the next day, and the probability of the next occurrence of the person who appears in the period is low, and has a chance.
And determining whether the target acquisition time is within the abnormal time period or not. If the target acquisition time is not in the abnormal time period, the attenuation activity of the target acquisition time is directly determined according to the time distance difference, which may be specifically referred to in embodiment one.
And step 203, if so, determining the attenuation activity of the target acquisition time according to the preset abnormal coefficient and the time distance difference.
The preset abnormality coefficient is associated with the abnormality time period, for example, when the abnormality time period includes a forward abnormality time period and a reverse abnormality time period, the abnormality coefficient includes a forward abnormality coefficient and a reverse abnormality coefficient, the forward abnormality coefficient is associated with the forward abnormality time period, and the reverse abnormality coefficient is associated with the reverse abnormality time period.
Specifically, if the target acquisition time is within the forward abnormal time period, determining the attenuation activity of the target acquisition time according to the forward abnormal coefficient and the time distance difference; and if the target acquisition time is within the reverse abnormal time period, determining the attenuation activity of the target acquisition time according to the reverse abnormal coefficient and the time distance difference.
In one possible embodiment, determining the attenuation activity of the target acquisition time according to the preset abnormal coefficient and the time distance difference comprises:
determining the attenuation activity of the target acquisition time according to the following formula:
wherein S represents the attenuation activity of the target acquisition time, beta represents an abnormal coefficient, P represents a preset basic activity value, alpha represents a preset attenuation coefficient, and T represents now Representing update time, T representing target acquisition time, T a Indicating a preset decay time.
Specifically, β represents an abnormal coefficient, and β includes β 1 And beta 2 Wherein, β 1 Coefficient of positive anomaly, beta 2 A reverse abnormal coefficient, if the target acquisition time is in the forward abnormal time period, the beta is taken as beta 1 If the target acquisition time is in the reverse abnormal time period, taking beta as beta 2 . Exemplary, 1<β 1 ，0<β 2 <1。
And step 204, determining whether the information storage position identification of the candidate is an access control terminal.
And determining whether the information storage position identification of the candidate is an access control terminal, namely determining whether the storage position of the face template information of the candidate in the current preset period is in a local database.
If the information storage location identifier of the candidate is not an access control terminal but a central server, the periodic activity of the candidate may be determined directly according to the activity of the collection time set, which may be specifically referred to as embodiment one, and is not described herein again.
And step 205, if yes, determining the periodic activity of the candidate personnel according to the preset switching cost value for switching and storing the face template information from the central database to the local database and the activity of the acquisition time set.
Because it takes a certain time and occupies a certain resource to send the face template information from the central server to the front-end entrance guard terminal, if the difference between the activity of the personnel in the central server and the activity of the personnel in the entrance guard terminal is too small, it is not necessary to send the face template information from the central server to the entrance guard terminal, otherwise, the resource waste is more than the efficiency improvement brought by sending the face template information. Therefore, a switching cost value for switching and storing the face template information from the central database to the local database is set in advance to indicate that if the person with liveness determined according to the collection time set in the local database is smaller than the person in the central database within the switching cost value, the position of the face template information of the person is not moved.
Specifically, if the information storage location identifier of the candidate is an access control terminal, the periodic activity of the candidate is the activity of the collection time set
And a switching cost value P switch And (4) summing.
And step 206, determining target personnel according to the periodic liveness of all the personnel, and storing the face template information of the target personnel in a local database of the access control terminal.
According to the embodiment of the invention, the activity of the personnel is determined according to the time of the personnel entering and exiting the access control by combining the time attenuation and the abnormal time period, and the activity of the candidate personnel is adjusted according to the switching cost value, so that the personnel information stored on the access control terminal and the personnel information stored in the central server terminal are adjusted according to the activity of the personnel, and simultaneously, the resource waste caused by information adjustment is reduced. The activity of the personnel is calculated in a more comprehensive and scientific mode, so that the candidate personnel stored on the access control terminal have a higher probability of hit rate, and the passing efficiency of the personnel is improved.
