When the face of the legitimate user of face identification unlock changes demand, it can open and function is unlocked based on recognition of face on its intelligent terminal
It can show the application program of face variation, and typing target time section and target object mark in the application program, such as: record
Enter target time section: " 2019-7-8 to 2019-8-8 " and target object identify " 100 ", and directly triggering, which generates, generates request, or
Person clicks " generation " or " determination " button by user, and triggering, which generates, generates request.
Wherein, it generates in request, may include target time section and target object mark, target time section can be in intelligence
It can install at the time of showing the application program of face variation based on recognition of face unlocking function in terminal between current time
Any time period, target object mark can be the intelligent terminal typing, be allowed through pair of recognition of face solution lock screen
The mark of elephant, such as: the mark of user's first can be the name of first, unlock number of first etc..Request is generated, for requesting from figure
As database all unlock images in obtain with generate request in carry information matches target image, specifically can be used for asking
Ask from all unlock images of image data base obtain shooting time in the target time period and object identity be target object
The target image of mark.
It is understood that before step 201, once user is mounted with based on recognition of face solution on its intelligent terminal
Lock function shows the application program of face variation, and for user when each recognition of face unlocks the intelligent terminal, the image of shooting is equal
By as unlock image, is obtained and existed to its corresponding image data base by the application program, simultaneously as recognition of face solution
When lock, each unlock image can correspond to the mark of the shooting time for generating the unlock image and the object for including in unlock image,
So, for the unlock image in the subsequent use that can be convenient image data base, the file destination of high quality is generated, for
Face's slight change of target object is watched at family, provides the user with better experience, the bat that can will be unlocked image, unlock image
Take the photograph the time with unlock the mark of objects in images is corresponding is stored in the corresponding image data base of the application program.Wherein, scheme
As preserving a plurality of data in database, what every data corresponding user generated when being unlocked by recognition of face: unlock is schemed
Picture-shoots shooting time (or being also possible to the unlocked time)-secondary unlock object identity of the unlock image.
It when specific implementation, is requested in step 201 in response to generating, target pair in target time section in acquisition image data base
As multiple corresponding target images, can specifically include: S11, parsing generate request, obtain target time section and target object；
S12 searches shooting time in the unlock image that target time section and object identity are target object, makees from image data base
For target object.
By step 201, it is high frequency time behavior using unlock intelligent terminal and shoots the characteristics of main body of image is face,
By obtaining and saving unlock image of the user when unlocking intelligent terminal by recognition of face, used unlock image as display
The resource of family face variation therefrom obtains the corresponding target image of user demand, to realize that true display user face is subtle
The effect of variation provides the data basis of high quality.
Step 202, it is based on target image, according to the sequencing of the corresponding shooting time of target image, generates target text
Part, file destination are used to characterize the face's variation of target object in the target time period.
It is understood that file destination can be based on target image generate one section of video, be also possible to one it is unreal
Lamp piece file can also be the file that can play other any formats of display, not limit specifically in the embodiment of the present application
It is fixed.
When specific implementation, after obtaining target image, can according to the sequence of the shooting time of target image from morning to night,
Or from evening to early sequence, target image is ranked up, and target image is generated into file destination according to the sequence, thus
So that when playing file destination, target is playd in order according to shooting time sequence from morning to night or from evening to early sequence
Image.
It is understood that the unlock image saved in image data base, in a kind of situation, it can be the intelligent terminal and exist
The original image shot when being unlocked, that is, without Face datection, the original image of characteristic point detection and face registration process；Separately
In a kind of situation, it is also possible to the intelligent terminal and Face datection, characteristic point detection and face is carried out to original image when being unlocked
Intermediate image after registration process.
As an example, if unlock image is original image when unlocking intelligent terminal, target is based in step 202
Image generates file destination, can specifically include according to the sequencing of the corresponding shooting time of target image: S21, by mesh
Logo image carries out Face datection, characteristic point detection and face registration process respectively, obtains the corresponding face image of target image；
S22 generates file destination based on face image according to the sequencing of the corresponding target image shooting time of face image.This
Sample obtains the corresponding face image of target image, then generate target text based on face image by handling target image
Part, so that can embody face variation of the user under equal angular in file destination, improving user, to observe its face thin
The experience of microvariations.
Wherein, Face datection, which refers to, detects the corresponding part of face in unlock image；Characteristic point detection can refer to
The image that Face datection is obtained carries out key point calibration, obtains the characteristic point in unlock image on face, such as: it can pass through
Dlib demarcates the algorithm of 68 key points of face, obtains 68 key point coordinates in unlock image on face, and scheme in unlock
It is marked as in；Face alignment, the key point on the face in image and average key point position corresponding on the face will be unlocked by referring to
Alignment, can specifically carry out face alignment using affine transformation method, and face alignment can be used for eliminating people in each unlock image
The angular deviation of object, make every unlock image in include be personage positive face, face alignment effect schematic diagram such as Fig. 3 institute
Show, wherein average face is the synthetic appearance of a certain group obtained by calculation before carrying out face alignment, is had average

Interval can be 0.1 second, then, it is assumed that it include 100 images in file destination, then, first image starts to play, and passes through
Start within 0.1 second to play second image, started to play third image using 0.1 second, and so on, play target text
Part takes around 10 seconds.
As another example, the play time interval of each adjacent two image to be played can be two neighboring wait broadcast with this
The shooting interval put between image is positively correlated.Wherein, the shooting interval between two neighboring image to be played, can be with
Refer to the time difference between at the time of shooting an image to be played and at the time of next image to be played of shooting.The example
In, in order to preferably show the linear character of face variation in time, the viewing experience of user is improved, in file destination
In, the play time interval of two neighboring image to be played, the shooting interval between two images to be played is related,
Specifically: the shooting interval between two images to be played is longer, and the play time interval of the two images to be played is set
That sets is longer, conversely, the shooting interval between two images to be played is shorter, the play time of the two images to be played
It is spaced shorter.Such as: it include image 1 to be played, image to be played 2 and image to be played 3 in file destination, and wait broadcast
It puts image 1 and image to be played 2 is adjacent, image 2 and image to be played 3 to be played are adjacent, it is assumed that image 1 to be played and to be played
The shooting interval of image 2 is 1 hour, and the shooting interval of image 2 and image to be played 3 to be played is 1 day, then,
It can be set and be divided between image 1 to be played and the play time of image to be played 2 0.1 second, image 2 to be played and image to be played
It is divided between 3 play time 2.4 seconds.
