Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Embodiment one
Referring to Fig.1, a kind of step flow chart of unlocking method in the embodiment of the present invention is shown.
Step 101, multiple facial images are obtained.
Specifically, user, which clicks HOME key etc., can trigger the key of unlocking mechanism.Mobile terminal receives triggering command, and
Open front camera.User is directed at front camera and makes multiple expressions, and mobile terminal obtains multiple faces by camera
Image.
Step 102, if multiple facial images are consistent with default facial image, the face table in every facial image is extracted
Feelings feature, and constitute human face expression characteristic sequence.
Under multiple facial images and storage default facial image unanimous circumstances in the terminal, i.e. multiple faces
Image is the image of mobile terminal holder, extracts the human face expression feature in every facial image, and by multiple human face expressions
Feature constitutes human face expression characteristic sequence.
Step 103, human face expression characteristic sequence is matched with presupposed information sequence.
Specifically, mobile terminal passes through the content and sequence in comparison human face expression characteristic sequence and presupposed information sequence,
Human face expression sequence is matched with presupposed information sequence.
Step 104, if successful match, the locking of mobile terminal is released.
If successful match, the locking of mobile terminal is released.If it fails to match, failure is unlocked.
In conclusion technical solution provided in an embodiment of the present invention, by obtaining multiple facial images；If multiple face figures
Picture is consistent with default facial image, then extracts the human face expression feature in every facial image, and constitute human face expression feature sequence
Column；Human face expression characteristic sequence is matched with presupposed information sequence；If successful match, the locking of mobile terminal is released,
To provide it is a kind of operate convenient, high safety unlock scheme, user experience is effectively promoted.
Embodiment two
Referring to Fig. 2, a kind of step flow chart of unlocking method in the embodiment of the present invention is shown.
Unlocking method of the invention needs to obtain default facial image and the default letter of setting before being unlocked operation
Cease putting in order for multiple text informations in sequence.Specifically, acquisition for mobile terminal presets facial image before unlock,
I.e. the facial image of equipment holder and store into memory.Also, the interface that mobile terminal user is provided by mobile terminal
Presupposed information sequence is set, is to carry out for { glad, indignation } with the content of presupposed information sequence in the present embodiment
It elaborates.Those of ordinary skill in the art are it should be clear that in other embodiments, the content of presupposed information sequence includes two and two
A any of the above quantity is used to describe the text information of expression, and putting in order for multiple text informations is specified by user, this
Any restriction is not done in invention to this.
Step 201, multiple facial images are obtained.
Specifically, user, which clicks HOME key etc., can trigger the key of unlocking mechanism.Mobile terminal receives triggering command, and
Open front camera.Mobile terminal obtains multiple facial images of user by front camera, wherein multiple facial images
In include user different expressions.In the present embodiment, mobile terminal holder is directed at camera and sequentially makes glad, indignation two
A expression,
Step 202, the facial characteristics of multiple facial images is extracted.
Specifically, extracting the specified facial characteristics of every facial image.In an embodiment of the present invention, extraction can be passed through
The face features such as eye, mouth, the nose of facial image.In other embodiments, other facial characteristics can also be extracted.
Step 203, facial characteristics is compared with the facial characteristics of default facial image.
Specifically, the facial characteristics that every facial image is extracted and corresponding facial characteristics in default facial image into
Row compares one by one.
Step 204, if facial characteristics is identical as the facial characteristics of default facial image, it is determined that multiple facial images and pre-
If facial image is consistent.
If the facial characteristics of every facial image facial characteristics corresponding with default facial image is identical, can determine
Multiple facial images got are consistent with default facial image, that is, active user is mobile terminal holder, continues step
205.If the facial characteristics in multiple facial images is not identical as the facial characteristics of default facial image, active user is not
The holder of mobile terminal, unlock failure.
Step 205, according to the acquisition sequence of multiple facial images, the human face expression successively extracted in every facial image is special
Sign, and sequence constitutes human face expression characteristic sequence.
According to the acquisition sequence of multiple facial images, the human face expression feature in every facial image is successively extracted.Face
Expressive features be can embody the feature of user's expression, such as：Glad, angry, surprised etc..In the present embodiment, the people of extraction
Face expressive features include：The minutias such as the corners of the mouth, eyebrow, canthus.In other embodiments, can also extract other can embody
The minutia of user's expression, the present invention do not do any restriction to this.Then, multiple human face expressions that mobile terminal will extract
Feature constitutes human face expression characteristic sequence according to sequence of extraction.It in the present embodiment, include indicating in human face expression characteristic sequence
Glad, indignation expressive features, and expressive features arranged in sequence.
Step 206, human face expression characteristic sequence is converted into text information sequence.
Specifically, putting in order according to multiple human face expression features in human face expression characteristic sequence, it successively will be multiple
Human face expression Feature Conversion is at corresponding text information, and sequence constitutes text information sequence.In this step, in the present embodiment
In, mobile terminal will indicate that glad, indignation expressive features are analyzed and processed in human face expression characteristic sequence, and output and table
The corresponding text information sequence of feelings feature { glad, indignation }.
Step 207, detect text information sequence in multiple text informations put in order in presupposed information sequence
Whether putting in order for multiple text informations be consistent.
Specifically, mobile terminal detects two texts by comparing text information sequence and presupposed information sequence
It content in sequence and whether consistent puts in order.
Step 208, if being detected as consistent, it is determined that successful match.
If be detected as consistent, it is determined that the expression and sequence of current mobile terminal holder's typing meet predetermined set,
Then successful match.
Step 209, if successful match, the locking of mobile terminal is released.
If successful match, mobile terminal unlocks.If matching is unsuccessful, failure is unlocked.
In conclusion technical solution provided in an embodiment of the present invention will by obtaining the facial image that multiple include expression
Facial image is compared with pre-set image, so that it is determined that multiple facial images whether be mobile terminal holder image, so
It afterwards again by extracting the human face expression feature in multiple facial images, and is text information sequence by human face expression Feature Conversion,
Text information sequence is matched with presupposed information sequence, to provide a kind of unlock side for operating convenient high safety
User experience is effectively promoted in case.
