Collection region.
102, when the collection area at the pixel of described collection is more than predetermined threshold value, by the pixel of described collection
Point composite finger print picture.
Wherein, above-mentioned the pixel composite finger print picture collected is comprised the steps that
21), the pixel of described collection is carried out binary conversion treatment；
22), by the pixel composite finger print picture after described binary conversion treatment.
Wherein, in step 11, can using the average of all pixels as binary-state threshold, according to this two
The pixel collected is carried out binary conversion treatment by value threshold value, obtains binaryzation pixel value.Specifically, if
Pixel value is more than this binary-state threshold, then, the value of this pixel value is 255, if pixel value is less than or equal to
This binary-state threshold, then, the value of this pixel value is 0.
It is of course also possible to the pixel composite finger print picture that directly will collect.
103, described fingerprint image is mated with preset fingerprint template.
Wherein, the feature of the image that can take the fingerprint respectively and the feature of preset fingerprint template, herein, feature can
It is characterized lines and characteristic point, then, it is judged that the phase of the feature of fingerprint image and the feature of preset fingerprint template
Whether like degree more than predetermined threshold value, this predetermined threshold value is the threshold value for unlocking setting, more than this threshold value,
Then can be to terminal unlocking, if less than or equal to this threshold value, then cannot unlock.
104, when described fingerprint image is with described preset fingerprint template matching success, terminal is unlocked.
Wherein, when fingerprint image is with preset fingerprint template matching success, terminal can be unlocked or right
Certain application in terminal is unlocked.Such as, it is in terminal and puts out under screen state, terminal is unlocked,
The display screen of terminal is lighted, and shows the desktop after unblock；Or, under terminal is in bright screen state,
Terminal is unlocked, the desktop after display unblock；Or, it is under released state in terminal, can be right
At least one application of terminal is unlocked, and i.e. starts this at least one application or shows this at least one should
The default page of a certain application in；Or, it is in terminal and puts out under screen state, can to terminal at least
One application is unlocked, i.e. start this at least one application or show in this at least one application a certain
The default page of application.
It can be seen that in the embodiment of the present invention, when detecting that user presses fingerprint recognition module, from fingerprint
Identify that the default collection point of module starts, gather pixel along default diagonal, in the pixel gathered
When the collection area of point is more than predetermined threshold value, the pixel composite finger print picture that will collect, by fingerprint image
Mate with preset fingerprint template, when fingerprint image is with preset fingerprint template matching success, terminal is entered
Row unlocks.Thus, owing to diagonally gathering fingerprint image, and only gather predetermined threshold value size
Fingerprint image, it is therefore possible to shorten the fingerprint image acquisition time, terminal unlocking efficiency can be improved.
With above-described embodiment as one man, refer to Fig. 2, a kind of unlocked by fingerprint side provided for the embodiment of the present invention
Second embodiment schematic flow sheet of method.Unlocked by fingerprint method described in the present embodiment, including following step
Rapid:
201, when detecting that user presses fingerprint recognition module, from the default collection of described fingerprint recognition module
Point starts, and gathers pixel along default diagonal.
202, when the collection area at the pixel of described collection is more than predetermined threshold value, by the pixel of described collection
Point composite finger print picture.
203, judge that whether described fingerprint image is image or the image of wet finger of dry finger.
In implementing, owing to the fingerprint lines in the fingerprint image of dry finger is intermittent, and wet finger
The fingerprint image larger area fingerprint lines obfuscation of fingerprint image, is almost hard to tell fingerprint lines, thus,
Can be by fingerprint image be analyzed, it is judged that whether fingerprint image comes from dry finger or wet finger.
Alternatively, can be dry to judge whether fingerprint image comes from by the patterned feature of the image that takes the fingerprint
Finger or wet finger.If the lines of fingerprint image is intermittent, then this fingerprint image belongs to dry finger, if
When occurring the fingerprint lines obfuscation of larger area in fingerprint image, then this fingerprint image belongs to wet finger.
Alternatively, can take the fingerprint the characteristic point of subregion of image；Judge the characteristic point of fingerprint image
Whether number is less than predetermined threshold value, if, it is determined that fingerprint image is the image of dry finger or wet finger
Image.Wherein, subregion can be the appointment region in fingerprint image, such as, with the center of fingerprint image
Region for the default size of round dot.Subregion can be the random areas in fingerprint image.Wherein, preset
Threshold value can be fixed threshold, or, predetermined threshold value can be relevant to the area of fingerprint image.
Alternatively, when fingerprint image is not from the image of the image of dry finger or wet finger, then can be straight
Connect and fingerprint image is mated with preset fingerprint template, if the match is successful, then terminal is unlocked, if
It fails to match, then prompting user re-enters fingerprint image.
204, if so, described fingerprint image is carried out image enhancement processing.
Wherein, the method that image enhancement processing is used can include but are not limited to: histogram equalization, ash
Degree stretching, image restoration, wavelet transformation etc..
205, the described fingerprint image after image enhancement processing is mated with preset fingerprint template.
206, when the described fingerprint image after image enhancement processing and described preset fingerprint template matching success,
Terminal is unlocked.
Alternatively, when the judged result of above-mentioned steps 203 is for being, can also carry out reduction and unlock threshold value, and sentence
Whether disconnected matching value between described fingerprint image and preset fingerprint template is more than the unblock threshold after described reduction
Value, the most then be unlocked terminal.
It is assumed that original unblock threshold value is 0.8, then, the unblock threshold value after reduction can be 0.6.Preferably,
One minimum unblock threshold value unlocked after threshold value reduces can be set, it may be assumed that the unblock threshold value after reduction needs to be more than
Or unlock threshold value equal to this minimum.
Alternatively, terminal determines the feature point number of fingerprint image, according to the feature point number of fingerprint image with
Difference and/or ratio between the feature point number of preset fingerprint template reduce unblock threshold value.
Such as, the feature point number of fingerprint image is A, and the feature point number of preset fingerprint template is B, unlocks
Threshold value is C, the unblock threshold value after reduction=C* (B-A)/B, during concrete calculating, if after Jiang Diing
Unlock threshold value and unlock threshold value less than minimum, in this case, directly minimum can be unlocked threshold value as reduction
After unblock threshold value.
Again for example, it may be determined that the feature point number of fingerprint image and the feature point number of preset fingerprint template, root
Reducing according to the difference of both feature point number and unlock threshold value, such as, difference is in the first preset range, then
Reducing by 10%, difference then reduces by 20% more than the first preset range.
Again for example, it may be determined that the feature point number of fingerprint image and the feature point number of preset fingerprint template, root
Reducing according to the ratio of both feature point number and unlock threshold value, such as, ratio is in the second preset range, then
Reducing by 10%, ratio then reduces by 20% more than the second preset range.Above-mentioned first preset range and second is preset
Scope can be configured according to practical application request or experience by user, does not repeats them here.
It can be seen that the terminal described in the embodiment of the present invention can detect that user presses fingerprint recognition mould
During group, from the beginning of the default collection point of fingerprint recognition module, gather pixel along default diagonal,
When the collection area of the pixel gathered is more than predetermined threshold value, the pixel composite finger print picture that will collect,
And when the image of the image that fingerprint image is wet finger or dry finger, fingerprint image can be carried out image increasing
Strength is managed, and then, is mated with preset fingerprint template by fingerprint image, in fingerprint image and preset fingerprint
During template matching success, terminal is unlocked, or, it is not that the image of wet finger is with dry at fingerprint image
During the image of finger, directly fingerprint image is mated with preset fingerprint template, when the match is successful, right
Terminal is unlocked.Thus, owing to diagonally gathering fingerprint image, and only gather default threshold
The fingerprint image of value size, it is therefore possible to shorten the fingerprint image acquisition time, can improve terminal unlocking efficiency.
Further, can user's finger is wet filter or be dried time, fingerprint image is carried out certain enhancement process, can carry
The quality of high fingerprint image, thus, more characteristics of image can be obtained from the fingerprint image after enhancement process,
Fingerprint matching efficiency can be improved, i.e. improve unlocked by fingerprint efficiency.
