Refer to the flow process signal that Fig. 1, Fig. 1 are a kind of touch-control pressure detection methods that the embodiment of the present invention provides
Figure.As it is shown in figure 1, this touch-control pressure detection method can include but not limited to following steps.
S101, gather the target fingerprint image of finger touching fingerprint sensor.
In the embodiment of the present invention, terminal is provided with fingerprint sensor, and this terminal is used by fingerprint sensor collection
The fingerprint of family finger, it is thus achieved that the target fingerprint image that this finger is corresponding.
As the optional embodiment of one, terminal collection touches the target fingerprint figure of the finger of fingerprint sensor
Picture, including:
After the information of terminal output typing fingerprint, detect whether that receiving finger touches fingerprint sensor
Operation;The most then terminal gathers the mesh corresponding to finger of current touch fingerprint sensor by fingerprint sensor
Mark fingerprint image;Or,
Terminal detect user's finger pressing operation of fingerprint sensor and judging press duration more than or etc.
When preset duration threshold value, the finger that terminal gathers current touch fingerprint sensor by fingerprint sensor is corresponding
Target fingerprint image;Or,
Terminal is more than or equal to preset in the operation and pressing area user's finger pressing fingerprint sensor being detected
During area threshold, terminal gathers the target corresponding to finger of current touch fingerprint sensor by fingerprint sensor
Fingerprint image.
Wherein, preset duration threshold value and preset area threshold value can be by terminal system default settings, it is also possible to by
End user manual is arranged, and the embodiment of the present invention is not especially limited.Such as, preset duration threshold value is 2 seconds
Clock, preset area threshold value is 1 square centimeter.
S103, by the target fingerprint image collected with preset template fingerprint image compare, detect mesh
Whether mark fingerprint image mates with template fingerprint image, if so, performs step S105;If it is not, terminate this stream
Journey.
In the embodiment of the present invention, terminal collects the fingerprint of current touch fingerprint sensor by fingerprint sensor
Target fingerprint image after, terminal or fingerprint sensor by the target fingerprint image collected with pre-set
Template fingerprint image carry out image recognition analysis, with detect target fingerprint image with preset template fingerprint figure
It seem no coupling.
It should be noted that template fingerprint image can be by terminal use's typing in advance, and the template of user's typing
Fingerprint image can be one, it is also possible to for multiple, if template fingerprint image is one, then terminal will gather
To target fingerprint image and this template fingerprint image carry out image recognition analysis, to judge to touch fingerprint
Whether the finger of sensor mates with the fingerprint in this template fingerprint image;If template fingerprint image is many
Individual, the most successively the fingerprint image touching the finger of fingerprint sensor is carried out respectively with multiple template fingerprint images
Image recognition analysis, with judge touch fingerprint sensor finger be specially in template fingerprint which.Its
In, multiple template fingerprint images can the same finger of corresponding user, it is also possible to corresponding same user is not
Same finger, it is also possible to the different fingers of corresponding different user, the embodiment of the present invention is not especially limited.
As the optional embodiment of one, whether detection target fingerprint image mates with template fingerprint image,
Including:
Whether the fingerprint lines in detection target fingerprint image mates with the fingerprint lines in template fingerprint image;
The most then crestal line thickness of fingerprint and the ridge of fingerprint in template fingerprint image in detection target fingerprint image
Whether line thickness mates;The result the most then detected is target fingerprint image and template fingerprint images match.
Concrete, the target fingerprint image collected and template fingerprint image are carried out image recognition by terminal, inspection
Whether the fingerprint lines surveyed in target fingerprint image mates, if so, with the fingerprint lines in template fingerprint image
The crestal line thickness of fingerprint and the crestal line of fingerprint in template fingerprint image during then terminal continues detection target fingerprint image
Whether thickness mates, the most then show that target fingerprint image matches with template fingerprint image.It is appreciated that
, for different people, the fingerprint lines of finger usually differs, and for same person
Different fingers, fingerprint lines is also otherwise varied, therefore, by the fingerprint in detection target fingerprint image
Whether lines mates with the fingerprint lines in template fingerprint image, can determine whether out the finger of touch fingerprint sensor
Whether it is same with the finger in default template fingerprint image, if same, then by detection target
In fingerprint image, whether the crestal line thickness of fingerprint is mated with the crestal line thickness of fingerprint in template fingerprint image and is analyzed
The crestal line thickness of the finger touching fingerprint sensor is the most consistent with the crestal line thickness of finger in template fingerprint image,
If consistent, then show complete of the image of the finger touching fingerprint sensor and the finger in template fingerprint image
Join.
As the optional embodiment of one, in detection target fingerprint image, the crestal line thickness of fingerprint refers to template
In print image, whether the crestal line thickness of fingerprint mates, including:
The crestal line thickness of fingerprint and the crestal line thickness of fingerprint in template fingerprint image in detection target fingerprint image
Whether difference is less than or equal to predetermined threshold value.
Concrete, predetermined threshold value can be by terminal system default setting, it is also possible to arranged by end user manual,
The embodiment of the present invention is not especially limited.Such as, if the crestal line thickness of the fingerprint in target fingerprint image is 0.02

Be set to wechat application, if terminal determine pressure rank corresponding to target fingerprint image attach most importance to by, then according to pressure
The corresponding relation of power rank and application program, getting is heavily wechat application by corresponding destination application.
S309, startup destination application.
In the embodiment of the present invention, if after terminal gets the destination application corresponding to goal pressure, start
This destination application, thus realize quickly starting application program.
Such as, the unlocking manner that terminal is arranged is unlocked by fingerprint, when terminal detects that user's typing fingerprint is carried out
During unblock, the target fingerprint image collected is compared with template fingerprint image, thus analyzes target
Pressure corresponding to fingerprint image, and then to inquire about the destination application corresponding to this goal pressure be KuGoo sound
Happy application, then terminal is unlocked, and directly initiates KuGoo music application after unblock, it is not necessary to user clicks on
KuGoo music icon on terminal homepage face, can directly initiate KuGoo music application after terminal unlocking, subtract
Lack the operation of user, improve the starting efficiency of end application.
Visible, by implementing the method described by Fig. 3, terminal gathers user's finger by fingerprint sensor
Target fingerprint image, and compare with the template fingerprint image pre-set, if detecting, target refers to
