Wherein, the number of continuous several times is preset in the electronic equipment before electronic equipment factory by technical staff , for example, can be 16 times, 17 times, it is 18 inferior, it is not limited here.

Wherein, the fingerprint picture includes each noise like etc. of fingerprint image and display screen predeterminable area.

S202, the electronic equipment export fingerprint typing guidance information, and work as and detect user for the predeterminable area Touch control operation when, execute cumulative reference operation according to multiple described fingerprint pictures, and export fingerprint typing successful information.

Wherein, the fingerprint typing guidance information is for prompting user's typing fingerprint, wherein the position including typing fingerprint Deng.

Wherein, when the number of continuous several times is 17 times, the current fingerprint typing guidance information that exports is the 18th time, but the At 18 times, the fingerprint picture of user is not obtained, but when detecting that user is directed to the touch control operation of predeterminable area, can be exported The successful message of this fingerprint typing informs user, is performed simultaneously the operation of cumulative benchmark.

Wherein, cumulative benchmark refers to the noise of the cumulative determining display screen predeterminable area according to multiple fingerprint pictures, thus Noise in removal fingerprint picture obtains the operation of the higher fingerprint template of quality, wherein when typing fingerprint each due to user The position of pressing and dynamics difference, and the position of noise (spot, barrier etc.) is identical, therefore, according to multiple fingerprint pictures The specific implementation of the cumulative noise for determining display screen predeterminable area can be the pixel according to plurality of pictures same position Gray value add up, and divided by picture number, the gray average of each pixel is determined, in the process for determining gray average In due to the dynamics of fingerprint and position it is different, cause the influence of fingerprint to become minimum, therefore, the ash formed by each pixel The picture that degree mean value obtains can be noise pattern piece.

S203, the electronic equipment repeat predetermined registration operation until during n-th executes the predetermined registration operation It detects that the cumulative reference operation executes completion, terminates the first operation executed in the predetermined registration operation, and export fingerprint record Enter to complete prompt information；

Wherein, the predetermined registration operation includes following operation: exporting the fingerprint typing guidance information, and the detection touching Control operation, and when detecting the touch control operation, the fingerprint typing successful information is exported, first operation includes institute Any operation in predetermined registration operation is stated, N is positive integer, and N can be 1,2,3 etc., it is not limited here.

Wherein, it detects that the cumulative reference operation executes to complete to detect the generation of following Target Photos to determine It states cumulative reference operation and executes completion.

Wherein, the electronic equipment repeats predetermined registration operation until during n-th executes the predetermined registration operation Detect that the cumulative reference operation executes the parallel work-flow completed as two processes, two parallel work-flows can be operation A: weight Predetermined registration operation is executed again；Operation B: whether the detection cumulative reference operation executes completion.

S204, the Target Photo that the electronic equipment storage is obtained according to the cumulative reference operation is as fingerprint template.

Wherein, the fingerprint template is for during unlocked by fingerprint, being compared the fingerprint image of typing, really later Determine whether fingerprint image matches with fingerprint template, upon a match, unlock operation could be executed.

In a possible example, described multiple fingerprint pictures according to execute cumulative reference operation, comprising:

Obtain the gray value of each pixel in every fingerprint picture；

According to the gray value of each pixel described in every fingerprint picture determine described in the in multiple fingerprint pictures First gray average of each pixel of one group of fingerprint picture；

According to the gray value of each pixel described in every fingerprint picture determine described in the in multiple fingerprint pictures Second gray average of each pixel of two groups of fingerprint pictures；

Determine first gray average and the identical multiple target pixel points of second gray average；

Using first gray average of the multiple target pixel points as noise mean value, and according to the noise mean value The noise for removing any one Zhang Zhiwen picture in multiple described fingerprint pictures obtains the Target Photo.

Wherein, every fingerprint picture is obtained by fingerprint mould group under same screen, that is to say, that every fingerprint picture Size with resolution ratio be as, i.e., the pixel array of every fingerprint image on piece be it is the same, therefore, according to every described The gray value of each pixel described in fingerprint picture determines in multiple described fingerprint pictures the described every of first group of fingerprint picture The specific implementation of first gray average of a pixel is, every fingerprint image on piece in first group of fingerprint picture is identical The gray value of the pixel of position is added, and then divided by the quantity of first group of fingerprint picture middle finger line picture, and then is determined each First gray average of pixel includes for example that 3 fingerprint pictures (are picture 1 respectively, scheme in first group of fingerprint picture Piece 2, picture 3), every fingerprint image on piece have 5 pixels (be respectively pixel 1, pixel 2, pixel 3, pixel 4, as Vegetarian refreshments 5), the first gray average of pixel 1 are as follows: (in picture 1 in gray value+picture 2 of pixel 1 pixel 1 gray value The gray value of pixel 1 in+picture 3)/3=pixel 1 the first gray average, pixel 2, pixel 3, pixel 4, as Described in the first gray average of the calculation method of first gray average of vegetarian refreshments 5 with pixel 1, this will not be repeated here.

Wherein, the concrete methods of realizing of second gray average is identical with the implementation method of above-mentioned first gray average, This will not be repeated here.

Wherein, since in multiple fingerprint pictures in first group of fingerprint picture, the noise of every fingerprint picture is constant (such as spot, scratch etc.), but the dynamics etc. that user presses in every fingerprint picture is different, and therefore, chooses first Gray average and the second gray average are identical for target pixel points, as noise pixel point.

Wherein, it is obtained according to the noise that the noise mean value removes any one Zhang Zhiwen picture in multiple described fingerprint pictures The specific implementation of the Target Photo is to subtract the gray value of multiple target pixel points in any one Zhang Zhiwen picture The picture obtained after first gray average is Target Photo.

Wherein, in multiple described fingerprint pictures the selection of any one Zhang Zhiwen picture can be it is diversified, such as can To be according to the variable quantity of gray value in multiple fingerprint pictures, it is described any one for choosing the maximum fingerprint picture of variable quantity Zhang Zhiwen picture, or can be and choose the least fingerprint picture of pixel quantity of same grayscale value in multiple fingerprint pictures and be Any one Zhang Zhiwen picture, it is not limited here.

As it can be seen that electronic equipment passes through first group of fingerprint picture and second by the way that multiple fingerprint pictures to be grouped in this example The gray average of each pixel of group fingerprint picture determines noise mean value, and then obtains and do not have noisy Target Photo, favorably In the quality for promoting fingerprint template in Target Photo.

In this possible example, the gray value of each pixel according to every fingerprint picture is true First gray average of each pixel of first group of fingerprint picture in multiple fixed described fingerprint pictures, comprising:

First group of fingerprint picture described in multiple described fingerprint pictures is divided at least two regions, in each region Including at least two fingerprint pictures；

At least reference gray level mean value of each pixel described in two fingerprint pictures is executed in each region parallel；

Each pixel of first group of fingerprint picture is determined according to the reference gray level mean value in each region First gray average.

Wherein, at least reference gray level of each pixel described in two fingerprint pictures is executed in each region parallel The specific implementation of mean value can be to be executed in each region at least two fingerprint pictures by multiple thread parallels The reference gray level mean value of each pixel, wherein the quantity of multiple threads can be the number of regions at least two regions Amount is consistent, can also be inconsistent, for example, the quantity of multiple threads can be 2, region quantity can be 4 or Thread Count Amount 4, region quantity 4, it is not limited here.

Wherein, the first gray average of each pixel is the reference gray level mean value phase of the corresponding pixel points in each region Add, the first gray average then obtained divided by the region quantity at least two regions.

As it can be seen that in this example, electronic equipment is by by multiple fingerprint picture subregions in first group of fingerprint picture, then simultaneously Row executes the reference gray level mean value in each region, and then determines the gray average of first group of fingerprint picture, improves serial execution Execution speed, and then promoted fingerprint template acquisition speed.

Multiple described fingerprint pictures are divided at least two groups fingerprint picture；

Parallel to execute third operation and the 4th operation, the third operation is in at least two groups fingerprint picture At least one set of fingerprint picture executes the operation of the cumulative benchmark to obtain the first reference picture, and the 4th operation is for institute State the behaviour that the fingerprint picture at least two groups fingerprint picture in addition at least one set of fingerprint picture executes the cumulative benchmark Make to obtain the second reference picture；

The Target Photo is determined according to first reference picture and second reference picture.

Wherein, the specific implementation of the Target Photo is determined according to first reference picture and second reference picture Mode can be diversified, such as can be that choose fingerprint template integrity degree in two reference pictures higher for target figure Piece, or can be choose fingerprint template in two reference pictures clarity it is higher for Target Photo etc., do not limit herein It is fixed.

Wherein, can also simultaneously it is parallel three operation, four operation etc., it is each operation be directed to one group or multiple groups fingerprint image Piece executes the operation of cumulative benchmark, it is not limited here.

As it can be seen that in this example, electronic equipment by executing third operation and the 4th operation parallel, rather than by multiple fingerprint images Piece carries out serial process, is conducive to promote the speed that fingerprint template obtains, avoids Caton, meanwhile, according at least two groups fingerprint image Two reference pictures that piece obtains determine last Target Photo, are conducive to promote quality and accuracy that fingerprint obtains.

It is described according to first reference picture and second reference picture determination in this possible example Target Photo, comprising:

Determine the coordinate and gray value of each pixel of the first fingerprint image in first reference picture；

Determine the coordinate and gray value of each pixel of the second fingerprint image in second reference picture；

According to the coordinate of each pixel of first fingerprint image and gray value and second fingerprint image The coordinate and gray value of each pixel generate the Target Photo.

Wherein, when typing fingerprint each due to user, the dynamics of pressing and the fingerprint region of typing are different, therefore, described According to each pixel of the coordinate of each pixel of first fingerprint image and gray value and second fingerprint image The specific implementation that the coordinate and gray value of point generate the Target Photo can be the pixel for determining the first fingerprint image With the pixel of the second fingerprint image number, when the second fingerprint image pixel be more than the first fingerprint image pixel When, pixel different from the gray value of pixel in the first reference picture in the second reference picture is obtained, according to the second reference The gray value of these pixels is added in the first reference picture by the coordinate of these pixels in picture, generates Target Photo, Or can be, when the pixel on the left of the first fingerprint image is more than the pixel on right side, choose the in the first reference picture Described in all pixels point group is combined on the right side of the second fingerprint image in one fingerprint image left side all pixels point and the second reference picture Target Photo, it is not limited here.

As it can be seen that the first reference picture and second that electronic equipment is obtained according to cumulative reference operation is with reference to figure in this example Piece determines final Target Photo, rather than just obtains Target Photo according to cumulative reference operation, is conducive to promote fingerprint mould The accuracy and integrity degree that plate obtains.

It is described to terminate the first operation executed in the predetermined registration operation in a possible example, comprising:

Determine whether the operation being currently executing is to detect the touch control operation；

If so, terminating the operation for executing the output fingerprint typing successful information in the predetermined registration operation；

If it is not, then terminating the operation being currently executing described in execution.

As it can be seen that electronic equipment first detects whether the operation being currently executing is touch control operation in this example, when being touch-control When operation, termination is the operation for exporting the fingerprint typing successful information, without terminating current touch control operation, is avoided defeated Out after fingerprint typing guidance information, there are no touch-controls by user, just see the unreasonable message that fingerprint typing is completed, are conducive to mention Rise electronic equipment interacted with user between reasonability.

In a possible example, the Target Photo obtained according to the cumulative reference operation that stores is as fingerprint Template, comprising:

Determine the semaphore of the Target Photo obtained according to the cumulative reference operation and the ratio of spatial noise；

When the ratio of the semaphore and spatial noise that detect the Target Photo is greater than preset threshold, institute is stored Target Photo is stated as fingerprint template.

Wherein it is determined that the semaphore of the Target Photo obtained according to the cumulative reference operation and the ratio of spatial noise The specific implementation of value includes the semaphore and spatial noise of determining Target Photo, then calculates semaphore and spatial noise Ratio, wherein the circular of the semaphore of Target Photo be determine fingerprint image in all salient points pixel First average value of gray value, and determine the second average value of the gray value of the pixel of all concave points, it is average by first Value and the second average value subtract each other the value for obtaining semaphore；Wherein, the circular of the spatial noise of Target Photo is to determine The flatness of concave point determines spatial noise according to flatness, and flatness is higher, and spatial noise is smaller, and flatness is lower, and airspace is made an uproar Sound is bigger.

As it can be seen that electronic equipment is by the semaphore of Target Photo and the ratio of spatial noise to Target Photo in this example Quality testing is carried out, when the ratio of semaphore and spatial noise is greater than preset threshold, shows the noise very little of Target Photo, into And Target Photo is stored as fingerprint template, be conducive to the reliability and accuracy that promote fingerprint template.
