Embodiments provide a kind of fingerprint input method and terminal, it is possible to be effectively realized fingerprint typing.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Terminal described by the embodiment of the present invention can include smart mobile phone (such as Android phone, iOS mobile phone, WindowsPhone mobile phone etc.), panel computer, palm PC, notebook computer, mobile internet device (MID, or Wearable etc. MobileInternetDevices), above-mentioned terminal is only citing, and non exhaustive, including but not limited to above-mentioned terminal.
Refer to Fig. 1, for the first embodiment schematic flow sheet of a kind of fingerprint input method that the embodiment of the present invention provides.Fingerprint input method described in the present embodiment, comprises the following steps:
101, gathering fingerprint shape, wherein, described fingerprint shape is gathered by touch screen, or, described fingerprint shape is gathered jointly by described touch screen and fingerprint recognition module.
In the embodiment of the present invention, the touch screen of terminal can be the touch screen supporting multiple point touching, and this touch screen can be used for gathering roughly the fingerprint profile of finger.Wherein, terminal can be gathered fingerprint shape by this touch screen, or, fingerprint shape can be gathered together with touch screen by fingerprint recognition module.This fingerprint shape is primarily referred to as the finger of user and carries out pressing the outermost profile of the finger-marks described on the touchscreen.Or, this fingerprint shape is primarily referred to as the finger of user and carries out the outermost profile of the finger-marks that pressing is formed on touch screen and fingerprint recognition module.It should be noted that preset fingerprint template can be pressed the average fingerprint shape of the fingerprint shape that described touch screen collects or maximum fingerprint shape at least one times by same the finger of user.Further, when storing fingerprint shape, the position of this fingerprint shape can also be stored.
Specifically, fingerprint recognition module can be used to gather fingerprint, can collect to degree of precision the feature lines of fingerprint.This fingerprint recognition module is touched screen around (being referred to Fig. 1 a), or, one end of fingerprint recognition module is close to the edge of touch screen (being referred to Fig. 1 b).In the embodiment of the present invention, when touch screen and fingerprint recognition module are pressed by user, available fingerprints identification module gathers fingerprint shape and target fingerprint together with touch screen, meanwhile, records the position of the fingerprint shape collected and the position of target fingerprint.
Preferably, when user is when the fingerprint recognition module that pressing fingerprint collecting area is less, namely the finger of user once presses fingerprint recognition module and collects partial fingerprints only, and fingerprint is acquired by the touch screen of user, this touch screen can be used for gathering the fingerprint shape of fingerprint, thus, the fingerprint positions of this fingerprint is determined by the position of fingerprint positions and fingerprint recognition module.The position of target fingerprint can be regarded as the coordinate position of the fingerprint that fingerprint recognition module collects, fingerprint recognition module also is understood as the coordinate position of this fingerprint recognition module, alternatively, before step 101, terminal also can the template of typing preset fingerprint on the touchscreen in advance, this preset fingerprint template can be one or more.The average for the fingerprint shape repeatedly pressing generation with a finger that preset fingerprint template can be collected by the touch screen of terminal, or, preset fingerprint template can be collected by the touch screen of terminal.
Such as, user can adopt same finger to press on the touchscreen, assume pressing n times, wherein this N is the integer more than or equal to 1, then, user face on the touchscreen presses each time and all can produce a fingerprint shape, so, n times pressing then can produce n times fingerprint shape, this n times fingerprint shape is taken average, then obtains the average of fingerprint shape.The average of this fingerprint shape is to be preset by pressuring template.It should be noted that owing under normal circumstances, fingerprint typing is imperfect, so needing to carry out repeatedly typing, the fingerprint shape of repeatedly typing averaged, then can obtain comparatively accurate fingerprint shape as preset fingerprint template.
Further, when terminal typing is over a preset fingerprint template, then preserving this preset fingerprint template, then, terminal can gather another fingerprint as another preset fingerprint template.Based on which, terminal can the multiple preset fingerprint template of typing in the terminal.
102, described fingerprint recognition module is utilized to gather target fingerprint.
In the embodiment of the present invention, press with finger in the process of fingerprint recognition module user, the fingerprint of finger can be gathered by fingerprint recognition module, i.e. target fingerprint, meanwhile, the position of this target fingerprint recordable, namely in terminal, the target fingerprint of storage can comprise pattern and position.
103, the first mapping area that described target fingerprint is mapped in described fingerprint shape is determined in the position according to described target fingerprint, described fingerprint shape and described fingerprint recognition module.
In the embodiment of the present invention, the position of target fingerprint it is known that fingerprint shape position it is also known that, thus, can determine that target fingerprint is mapped in the first mapping area in fingerprint shape according to the position of target fingerprint, fingerprint shape and fingerprint recognition module.Wherein, carry out in fingerprint Input Process user at fingerprint recognition module, the position of the position of this fingerprint shape, target fingerprint can be obtained, the position of this fingerprint shape is carried out overlapping with the position of fingerprint recognition module, using both common region as target area, it is clear that this target area comprises target fingerprint.Thus, then mark the region of target fingerprint in the region of interest, thus, it may be determined that the area maps of target fingerprint the first mapping area in fingerprint shape.
104, extract the feature lines of described target fingerprint and preserve described feature lines.
In the embodiment of the present invention, the target fingerprint that fingerprint recognition module can be collected by terminal carries out contours extract, thus, the feature lines obtained after this contours extract is exactly target fingerprint, and preserves this feature lines.
Alternatively, terminal can determine whether whether this feature lines completely fills this first mapping area, if this first mapping area is filled out is filled with feature lines, so, step 105 can be performed, if this first mapping area is not filled by full feature lines, namely judge the feature lines that whether there is disconnection in this first mapping area, user then can be pointed out to carry out fingerprint pressing operation continuing with this first mapping area, namely re-execute step 101.
105, prompting user, to carry out fingerprint typing operation to other regions except described first mapping area in described fingerprint shape.
In the embodiment of the present invention, terminal can point out user that the region except the first mapping area in preset fingerprint template is carried out fingerprint typing operation, pass through which, can when fingerprint recognition module is less, by fingerprint piecemeal typing, finally, the fingerprint of repeatedly typing is spliced, thus, a complete finger print can be formed, this fingerprint can be described as cryptographic fingerprint.Obviously, it can be seen that as long as cryptographic fingerprint typing is complete, the overall big I of this cryptographic fingerprint is consistent with preset fingerprint template size.Alternatively, after step 105 completes, step 101 can be returned to, continue to complete as procedure described above the fingerprint typing operation in other regions except the first mapping area in preset fingerprint template.
Alternatively, first mapping area position in preset fingerprint template can be shown by terminal on a display screen, and the region beyond the first mapping area is carried out labelling, to point out user that the region beyond the first mapping area carries out fingerprint typing operation.
nullAlternatively，Assume that the fingerprint that step 101 gathers is shaped as a fingerprint shape，The target fingerprint gathered is a target fingerprint，After step 105，User can carry out pressing fingerprint recognition module again，Then terminal can continue to gather fingerprint shape and target fingerprint，The fingerprint continuing to collect is shaped as secondary fingerprint shape，The target fingerprint continuing to gather is secondary target fingerprint，So，According to secondary fingerprint shape、The second mapping area that secondary target fingerprint is mapped in secondary fingerprint shape is determined in the position of secondary target fingerprint and fingerprint recognition module，Second mapping area and the first mapping area are overlapped，If the first mapping area and the second mapping area completely fills a whole fingerprint shape，Then point out user，Fingerprint typing success，If the first mapping area and the second mapping area are not filled up completely with this fingerprint shape，Then the extra-regional region of conjunction of the first mapping area and the second mapping area is carried out fingerprint typing operation by prompting user.
Pass through the embodiment of the present invention, gather fingerprint shape, wherein, this fingerprint shape is gathered by touch screen, or, this fingerprint shape is gathered jointly by this touch screen and fingerprint recognition module, utilizes this fingerprint recognition module to gather target fingerprint, determines, according to the position of this target fingerprint, fingerprint shape and fingerprint recognition module, the first mapping area that target fingerprint is mapped in this fingerprint shape；Extract the feature lines of this target fingerprint and preserve this feature lines；Prompting user, to carry out fingerprint typing operation to other regions except described first mapping area in this fingerprint shape.Thus, the available touch screen of user and fingerprint recognition module gather fingerprint shape and target fingerprint simultaneously, determine that partial fingerprints that this fingerprint recognition module collects is relative to the first mapping area in fingerprint shape by the position of this target fingerprint, fingerprint shape and fingerprint recognition module, by which, fingerprint Input Process can be effectively realized.Being particularly suited in less fingerprint recognition module can piecemeal typing user's complete finger print.
Refer to Fig. 2, for the second embodiment schematic flow sheet of a kind of fingerprint input method that the embodiment of the present invention provides.Fingerprint input method described in the present embodiment, comprises the following steps:
201, gathering fingerprint shape, wherein, described fingerprint shape is gathered by touch screen, or, described fingerprint shape is gathered jointly by described touch screen and fingerprint recognition module.
202, described fingerprint recognition module is utilized to gather target fingerprint.
203, described fingerprint shape is mated with preset fingerprint template.
In the embodiment of the present invention, from the foregoing, it will be observed that preset fingerprint template is the fingerprint shape of typing in advance, then, fingerprint shape can be mated by terminal with preset fingerprint template, and detailed process can be as follows:
First, terminal can calculate the matching degree between fingerprint shape and preset fingerprint template, then, it is judged that whether this matching degree is more than predetermined threshold value, and when this judged result judged is as being, this fingerprint shape is successful with this preset fingerprint template matching.Under normal circumstances, can being used for weighing two width images match degree based on structural similarity (StructuralSimilarity, SSIM), its matching degree is closer to 1, then, fingerprint shape is more high with preset fingerprint template more matching degree, and maximum match degree is 1.Owing to SSIM is prior art, do not repeat them here.Thus, can directly calculate the matching degree between fingerprint shape and preset fingerprint template, if this matching degree is more than predetermined threshold value, so, it is believed that preset fingerprint template and fingerprint form fit, namely may know that the fingerprint of the finger that the fingerprint of finger corresponding to preset fingerprint template is corresponding with this fingerprint shape is the same, namely both come from the fingerprint of same finger.Wherein, this predetermined threshold value can be 0～1, it is preferable that this predetermined threshold value can be 0.8.
Further, in the fingerprint shape matching process with preset fingerprint template, it is also possible to fingerprint state and preset fingerprint template are carried out overlap operation, if, fingerprint shape and preset fingerprint template can be completely overlapped, then, fingerprint shape and preset fingerprint template matching can be described.
204, when described fingerprint shape is with described preset fingerprint template matching, determine, according to the position of described target fingerprint, described fingerprint shape and described fingerprint recognition module, the first mapping area that described target fingerprint is mapped in described fingerprint shape.
205, extract the feature lines of described target fingerprint and preserve described feature lines.
206, prompting user, to carry out fingerprint typing operation to other regions except described first mapping area in described fingerprint shape.
In the embodiment of the present invention, terminal can point out user that the region except the first mapping area in preset fingerprint template is carried out fingerprint typing, pass through which, can when fingerprint recognition module is less, by fingerprint piecemeal typing, finally, the fingerprint of repeatedly typing is spliced, thus, the fingerprint of a complete finger can be formed, this fingerprint can be described as cryptographic fingerprint.Obviously, it can be seen that as long as cryptographic fingerprint typing is complete, the overall big I of this cryptographic fingerprint is consistent with preset fingerprint template size.
Alternatively, first mapping area position in preset fingerprint template can be shown by terminal on a display screen, and the region beyond the first mapping area is carried out labelling, to point out user that the region beyond the first mapping area carries out fingerprint typing operation.
Further, after user completes the fingerprint of a complete finger, terminal also can the fingerprint of other fingers of typing.
Further, after the complete fingerprint of terminal typing, can be used for this fingerprint terminal is encrypted, thus, the safety of terminal can be improved.So, in decrypting process, terminal may utilize the touch screen of this terminal and fingerprint recognition module gathers fingerprint simultaneously, the position utilizing the position of this target fingerprint, fingerprint shape and fingerprint recognition module determine fingerprint (i.e. target fingerprint) that fingerprint recognition module collects relative to preset fingerprint template (or, cryptographic fingerprint) opposed area, the feature lines of target fingerprint is mated with the feature lines of cryptographic fingerprint, if the match is successful, terminal can be decrypted.
In specific implementation process, can refer to Fig. 1 a, in the embodiment of the present invention, the induction region of fingerprint recognition module can be designed in the induction region of touch screen, so, before being actually typing fingerprinting operation, first the fingerprint of finger can be pressed against the induction region of touch screen, and the region of user's pressing all with the induction zone of fingerprint recognition module without common factor, and record fingerprint shape that finger presses to form preset fingerprint template.User can press repeatedly with the fingerprint of same finger, and calculates this average fingerprint shape as preset fingerprint template.In fingerprint Input Process, detect current finger print position and fingerprint shape by touch screen and fingerprint recognition module and combine the overall shape forming current finger print, then mate with default template finger, after the match is successful, the first mapping area of the target fingerprint of current typing can be accurately known further according to the position of the position of current goal fingerprint, fingerprint shape and fingerprint recognition module, thus, effectively determine the pressing position of user, efficiently solve the problem that typing region is not enough.
Alternatively, in specific implementation process, can refer to Fig. 1 b, the induction region of fingerprint recognition module can be designed side under a touch screen, so, before being actually typing fingerprinting operation, first the fingerprint of finger can be pressed against the induction region of touch screen, and the region of user's pressing all with the induction zone of fingerprint module without common factor, and record fingerprint shape that finger presses to form preset fingerprint template.User can press repeatedly with the fingerprint of same finger, and calculates this average fingerprint shape as preset fingerprint template.In fingerprint Input Process, current finger print position and fingerprint shape is detected by touch screen and fingerprint recognition module, less at fingerprint recognition module, the fingerprint shape of the fingerprint collected based on this touch screen and fingerprint recognition module can be partial shape, this partial shape can be mated with preset fingerprint template, after the match is successful, the region of target fingerprint typing can be accurately known further according to the position of the position of target fingerprint, fingerprint shape and fingerprint recognition module, thus, effectively determine the pressing position of user, efficiently solve the problem that typing region is not enough.
nullAlternatively，Assume that the fingerprint that step 201 gathers is shaped as a fingerprint shape，The target fingerprint gathered is a target fingerprint，Wherein，Can using fingerprint shape as preset fingerprint template，After step 206，User can carry out pressing fingerprint recognition module again，Then terminal can continue to gather fingerprint shape and target fingerprint，The fingerprint continuing to collect is shaped as secondary fingerprint shape，The target fingerprint continuing to gather is secondary target fingerprint，So，Secondary fingerprint shape can be mated with a fingerprint template，If coupling，Then illustrate that secondary fingerprint shape is the same with a fingerprint shape，Namely，The finger of twice pressing fingerprint is same finger，Then can according to secondary fingerprint shape、The position of secondary target fingerprint and fingerprint recognition module determine secondary target fingerprint be mapped in fingerprint shape (or，Secondary fingerprint template) in the second mapping area，If the first mapping area and the second mapping area have had been filled with this preset fingerprint template，So，Fingerprint typing success，If the first mapping area and the second mapping area have had been filled with this preset fingerprint template，So，Prompting user，So that other regions except the first mapping area and outside the second mapping area in this fingerprint shape are carried out fingerprint typing operation.
