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.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a method for storing face data of an access control device according to an embodiment of the present invention. The embodiment is applicable to the condition that the face data of the user is pre-stored before the face recognition is carried out by the access control equipment, the method can be executed by the storage device of the face data of the access control equipment provided by the embodiment of the invention, the device can be realized by a hardware and/or software mode, and the device can be generally integrated in a server. As shown in fig. 1, the method specifically comprises the following steps:
and S11, receiving the face picture uploaded by the user.
Specifically, when a user has a demand for face recognition, if the user becomes a resident of a certain cell, the user needs to enter the cell through the face recognition function of the access control device, the storage of face data can be completed in advance, so that the face data can be compared during face recognition, the user can upload a face picture of the user to a server, the server can process and store the face picture, and the server can be specifically a characteristic value scheduling server. After receiving the face photos, the server can firstly detect the quality of the face photos, if the quality is unqualified, the server can directly judge that the current task fails, and can prompt the user so that the user can upload the photos again, and if the quality is qualified, the server can perform subsequent steps.
And S12, issuing the face photos to at least one type of target access control equipment according to a preset scheduling rule.
Specifically, the method adopts a distributed scheduling algorithm, after receiving a face photo uploaded by a user, a server can issue the face photo to various access control devices, and the edge access control devices complete subsequent characteristic value extraction. The target access control device to be issued may be determined according to a preset scheduling rule, and then the face photos may be issued respectively. Before determining the target access control device, the access control devices managed by the server may be first classified according to information such as different manufacturers and/or different chip models used, so as to obtain the at least one type. After the classification is finished, the target access control equipment to be issued can be determined in each type of access control equipment according to the preset scheduling rule, and the face photos can be issued to each type of target access control equipment, so that each type of actually used access control equipment can realize the face recognition function by applying the feature values obtained by subsequent extraction.
Optionally, the issuing the face picture to at least one type of target access control device according to a preset scheduling rule includes: determining a scheduling weight score according to one or more of signal quality between the current online access control equipment, load state of the current online access control equipment, real-time task state and geographic position, and determining each type of target access control equipment in the current online access control equipment according to the scheduling weight score. Specifically, when a photo is required to be issued, the current online access control device may be determined in the access control devices managed by the server, and then the scheduling weight score of each access control device may be determined according to one or more factors of the load state, the real-time task state, the geographic position of each current online access control device and the signal quality between the server, so that a target access control device may be selected in each type according to the scheduling weight score of each access control device, and specifically, the higher the scheduling weight score is, the priority is, the selection is made. The load state may include a processor utilization rate, a memory utilization rate, and the like, and may reflect a capability of the access control device to process a new task, and during scheduling, the access control device with a lower load state may be preferentially selected, that is, a higher load weight score may be set for the access control device with a lower load state. The real-time task state can include whether the access control equipment is currently carrying out face recognition, audio and video conversation, characteristic value extraction and other tasks, the task weight score can be adjusted for each task, the real-time task state can reflect the speed of the access control equipment for processing a new task, and during scheduling, the access control equipment with the idle real-time task state can be preferentially selected, so that the access control equipment with the idle real-time task state can be set with a higher task weight score. The geographical position can be a city, a community or a specific position where the access control equipment is installed, the position relation of a user uploading the face photos can be reflected, when the access control equipment located in the same community or the same city with the user can be selected preferentially, a higher position weight score can be set for the access control equipment in the same community or the same city, and a higher position weight score can also be set for the access control equipment closer to the user according to the distance between the access control equipment and the user. The signal quality can be the heartbeat signal intensity between entrance guard's equipment and the server, can reflect the signal transmission efficiency between entrance guard's equipment and the server, and when the dispatch, can the higher entrance guard's equipment of preferred selection signal quality, can set up higher signal weight score for the higher entrance guard's equipment of signal quality. When the scheduling weight score is determined according to the signal quality, the load state, the real-time task state and the geographic position, the required scheduling weight score can be obtained by adding the load weight score, the task weight score, the position weight score and the signal weight score.
Further optionally, before the sending the face photos to at least one type of target access control device according to the preset scheduling rule, the method further includes: receiving the heartbeat signal intensity sent by the access control equipment to detect whether the access control equipment is on line or not and the signal quality; and/or receiving the load state and/or the real-time task state sent by the access control equipment at regular time. Specifically, keep the heartbeat between each entrance guard's equipment and the server, detect and send heartbeat signal intensity for the server, when the server received the heartbeat signal intensity that entrance guard's equipment sent, can confirm that the entrance guard's equipment that corresponds is currently in the on-line condition according to this heartbeat signal intensity to can judge obtain with the signal quality between the entrance guard's equipment that corresponds, corresponding, if do not receive the heartbeat signal intensity that entrance guard's equipment sent, then can think that the entrance guard's equipment that corresponds is not online at present. On the other hand, each access control device can also send the load state and/or the real-time task state of the access control device to the server at regular time, so that the server obtains the load state and/or the real-time task state used for current access control device scheduling. In addition, the geographical position of each access control device can be stored in the server in advance for use.
And S13, extracting the exclusive characteristic value of the face photo corresponding to the type of the target access control device, returning the exclusive characteristic value, and deleting the local face photo.
Specifically, after the face photos are issued according to the preset scheduling rules, the target access control device receiving the face photos can extract the exclusive characteristic value of the type of the target access control device through the chip and the algorithm used by the target access control device, and return the exclusive characteristic value to the server, so that the local face photos of the target access control device can be deleted immediately, and leakage is avoided.
And S14, storing the received exclusive characteristic value, and deleting the face photo when the exclusive characteristic value returned by all types of target access control equipment is received.
Specifically, the server can store the exclusive characteristic value after receiving the exclusive characteristic value, when all types of target access control devices return the exclusive characteristic value, namely the server obtains the exclusive characteristic value of all types which can be used for face recognition, the current characteristic value extraction task can be considered to be successfully completed, and the face picture in the server can be deleted to avoid leakage.
Optionally, the number of each type of the target access control device is multiple; correspondingly, the storing the received exclusive characteristic value includes: for each type, only the first returned target-specific feature value is received and stored. Specifically, when determining each type of target access control device, multiple target access control devices (e.g., more than three) may be determined according to a preset scheduling rule, and for example, the first access control devices with larger scheduling weight scores may be used as the target access control devices, so as to improve the success rate of feature value extraction. Correspondingly, the server only needs to store the first returned target-specific characteristic value. Furthermore, the target access control device can upload the exclusive characteristic value to the temporary object storage server at first, when the corresponding exclusive characteristic value is obtained for each type in the temporary object storage server, the first target exclusive characteristic value successfully extracted in each type can be dumped to the characteristic value scheduling server, and other characteristic values received later can be directly discarded, and the method can be realized by regularly cleaning the temporary data in the temporary object storage server. By determining a plurality of target access control devices and only receiving the target exclusive characteristic value returned fastest, the distributed scheduling algorithm provided by the method is more efficient and stable.
Further optionally, after receiving and storing the first returned target-specific feature value, the method further includes: and informing other target access control devices of the same type as the target access control device returning the target exclusive characteristic value to stop the current characteristic value extraction task. Specifically, for a certain type, after the target exclusive eigenvalue which is returned firstly is obtained, other target access control devices can be informed to stop the current eigenvalue extraction task, and therefore resource waste is reduced.
On the basis of the above technical solution, optionally, the method further includes: and if the result returned by receiving one type of target access control equipment is extraction failure, judging that the results of the current characteristic value extraction tasks of all types of target access control equipment are failure. Specifically, the method can provide a quick error mechanism, when all the results returned by any type of target access control equipment are extraction failures, the results of the current characteristic value extraction tasks of all types of target access control equipment can be directly judged to be failures without waiting for the results returned by all types of target access control equipment, the current characteristic value extraction tasks can be ended, and the result failure indicates that the characteristic value extraction of the currently processed face photos fails, so that the face recognition requirements of all the access control equipment cannot be met, and a user can be prompted to upload again or corresponding staff can be notified to maintain.
On the basis of the above technical solution, optionally, the method further includes: if the received result returned by the target type of the target access control equipment is extraction overtime, determining new target access control equipment in the target type of the access control equipment again according to the preset scheduling rule; and if the retry times reach the preset retry upper limit and the returned result is still the overtime extraction, judging that the result of the target access control equipment of the target type is overtime failure, and judging that the results of the current characteristic value extraction tasks of all types of target access control equipment are failure. Specifically, the method may further provide a retry mechanism, when a result returned by a target access control device of any target type is extraction timeout, re-determining access control devices except for the scheduled access control device as the target access control devices to extract the exclusive feature value in the corresponding target type of access control devices according to a preset scheduling rule, and if the extraction timeout is still returned, re-determining the target access control devices again until the retry number reaches a preset retry upper limit, determining that the result of the target type is timeout failure, and directly determining that the result of the current feature value extraction task of the target access control devices of all types is failure, without waiting for the results returned by the target access control devices of all types, the current feature value extraction task may be ended. If the overtime failure indicates that the corresponding access control equipment is possibly busy or fails, the user can be prompted to retry later or corresponding staff is notified to perform maintenance.
According to the technical scheme provided by the embodiment of the invention, firstly, a face photo uploaded by a user is received, then the face photo is issued to at least one type of target access control equipment according to a preset scheduling rule, so that an exclusive characteristic value of the face photo is extracted through the target access control equipment, the exclusive characteristic value is returned, then the local face photo is deleted, finally, the received exclusive characteristic value returned by the target access control equipment is stored, and the face photo is deleted when the exclusive characteristic values returned by all types of target access control equipment are received. Carry out the extraction of eigenvalue through issuing entrance guard's equipment with the face photo, return the eigenvalue to the server and save again, realized the adaptation to all types of entrance guard's equipment, to arbitrary entrance guard's equipment, all can realize the utilization to the eigenvalue, simultaneously through accomplish the face photo that deletes local used after the extraction of eigenvalue at local equipment promptly, and delete the face photo that high in the clouds used promptly after the exclusive eigenvalue that all types of target entrance guard's equipment returned at high in the clouds server, fine has avoided the risk that face privacy revealed.
