(4) attendance information function is uploaded.If engineer has passed through face verification, on the successful information that should will register is real-time
It reaches in server and is stored.
(2) engineer's pictorial information module is obtained
Since the picture raw information of engineer is stored in database server, engineer end need to have reading number
According to the function of the face_token stored in library.Engineer's client completes the operation of this module, similar to management end, inquiry
Content is department table and the information in engineer's information table.The difference lies in engineer's information tables that engineer end is read
In information be engineer face_token.Into after the interface of display department information, engineer selects the department of oneself,
Then it can enter in the interface of engineer's information selection.If you need to help, other people carry out attendance and register, and select other people information
.The module flow diagram is identical with the flow chart that management end shows attendance information.In order to ensure the number in database server
According to synchronous with the data holding in client-side program, the refreshing button of engineer's information should be also set.To after this step, engineer
The personal information of oneself can be selected, into the part of registering based on recognition of face.
Figure 13 is the interface that engineer end obtains original image information module, and left figure is department information query interface, is selected
Enter right figure engineer's information inquiry interface after corresponding department, engineer's name is selected to enter interface of registering again.
(3) attendance on off state module is detected
According to network analysis and user demand, manager can control registering the period for engineer at any time, thus engineer
End should also be equipped with the button of detection attendance on off state.When attendance order is issued at manager end, engineer can just carry out attendance
It registers.If Figure 14 is the flow chart that attendance on off state is detected at engineer end.
Figure 15 shows that the attendance of engineer end is registered the interface of module, and engineer clicks detection attendance and registers opening
After button, engineer's client sends the order of status values in inquiry control table to database server, if inquire
Status values are 0, then prove to register not open also, and engineer's client will close all buttons at interface of registering at this time, and
And prompting is popped up in interface, attendance is not yet turned on.If it is 1 to inquire status values, prove that manager has turned on label at this time
It arrives, and the prompting that attendance has turned on, next operation that engineer can be taken pictures is popped up in the interface at engineer end.
Engineer's client detects whether attendance opens by this process, with this.
(4) photo module
When realizing face alignment function, engineer's client must be come by using the camera of Android intelligent
Acquisition face picture in real time.If Figure 16 is photo module flow chart.
It realizes the partial function, needs that Button (button) and Imageview should be defined in interface (picture is shown).
Below come background function that after realizing and clicking on, android system performs.
(1) it clicks on, engineer's client is carried by using the method for intent to call android system
Camera is taken pictures interface, so as to start camera.
(2) after engineer completes to take pictures, slave phase chance returns to the bitmap data for acquisition of taking pictures, and at this time protects bitmap data
Picture file is saved as, and fixes the position of its storage.In view of engineer's client after repeatedly registering, it is possible to occur
Preserve the problem of picture file is excessive.Therefore, when picture stores, the title of picture file can be fixed.Assuming that at this time into
The process of row once photo taking, picture have been stored to fixed position, if being taken pictures for the second time again, by acquisition of taking pictures for the second time
The operation that picture will directly cover the picture previously obtained saves phone memory by this process to reach
Purpose.
(3) in the interface of Android phone, since control ImageView has limitation, picture mistake to the size of picture
Conference causes memory spilling to lead to program crashing, therefore the picture being shown in Android interface is also needed to carry out compression processing.
After picture storage is completed, processing is compressed it, and it is included using the method BitmapFactory that Android is carried
In interface.
(5) face alignment module
In this set system, face alignment module is the face alignment technology based on Face++.By the way that picture is uploaded to
Face++ servers, you can get the similarity of two face pictures, two faces can determine whether according to the stool and urine of similarity
Whether the personage in picture is same person.If Figure 17 is face comparing module flow chart.
The function of the module is integrated in the background processes of photo module, i.e., after Android phone is taken pictures, directly into
The operation of row face alignment.The function of carrying out face alignment module below is realized：
(1) after taking pictures, background program reads the absolute path that picture stores in mobile phone.
(2) function is related to network access, since network access functions typically more expend the time, main line in order to prevent
Journey is blocked, and the process of face alignment has to complete in sub-line journey.In the face alignment functional development document of Face++,
Face++ servers define the call format of several upload informations, and software developer can upload accordingly according to their needs
Data.In this module, upload data and include developer in the Face++ api_key applied and api_secret, original image
Face_token and the picture that obtains after taking pictures.Wherein, face_token is obtained by database server, after taking pictures
The picture of acquisition then needs to carry out certain processing can to upload.
(3) according to developer's document of Face++, the picture needs obtained after taking pictures are converted into meeting its upload requirement
Form, the method by the way that android system is called to carry first obtain picture path, then the picture under the path is carried out two into
System conversion, so as to which it be made to meet the requirement of Face++ servers.
(4) when uploading relevant information, according to developer's document of Face++, engineer's client need to use post modes
It will be in specified content uploading to Face++ servers.It uploads content and includes developer in the Face++ api_key applied and api_
Secret, the face_token of original image, the binary data obtained after picture conversion.
(5) if Face++ servers are successfully received the information of engineer's client upload, JSON forms can be returned
Parameter.When engineer's client upload parameter is wrong, error message can be included in the result returned from Face++ servers, is opened
Originator can further debug software according to error message.If upload parameter meets the requirements, Face++ servers
The relevant information of face can be returned to, these information mainly include, the face location of two pictures, and request expends the time, Yi Jiren
Face similarity degree etc..
Figure 18 is the JSON formatted data examples that Face++ servers return.
Wherein, the face information in uploading pictures is store in faces1, after store face alignment in confidence
The similarity information of acquisition.

It needs to parse the information of human face similarity degree, therefore need to only create the JAVA object of storage human face similarity degree.
(2) a GSON object is created in the backstage of face alignment module, which is stored in face letter for reading
Cease the similarity information in class.
(3) by calling the method in GSON, human face similarity degree information is extracted.Due to the similarity of initial storage
The data type of information is character type, therefore also needs character type being converted to floating type.A floating type variable is defined, by character type
Data unsteady state operation is floating type.Such operation, can be in order to judging human face similarity degree.
(4) after the information for successfully extracting human face similarity degree, judgement operation can be carried out.What if Face++ servers returned
Human face similarity degree is sky, then the picture for illustrating to upload is likely to occur problem, at this moment shows error message in interface of registering.If into
Work(gets human face similarity degree, and is worth and is more than 70, then exports the prompt message successfully registered, and opens and upload information of registering
Button；Conversely, then export the human face similarity degree of register failure and scene acquisition.
(5) the interior progress in sub-line journey due to above-mentioned face alignment process, and android system does not allow in sub-line journey
The program of operation repeats to refresh the information that control is shown in interface, therefore Message objects need to be created in sub-line journey, thus will be sub
Content in thread is sent in main thread, so as to refresh client end interface.In main thread, can open one it is new
The parameter that Handler receptions are contained by the Message objects being transmitted in sub-line journey, thus by handler to system interface
Refreshed in real time.
Such as the interface that Figure 20 is face comparison result, left figure is compares successfully, and middle figure is to compare failure, and right figure is does not detect
To face.
