Description
Technical field
The present invention relates to characteristics of human body's extractive technique field, specifically, it is related to a kind of many fingerprint syncs of mobile phone camera
Extracting method and system.
Background technology
In today of network times, in various places, we are nearly all stepped on carrying out fingerprint using various smart machines
Record, fingerprint pay and fingerprint identity validation, and corresponding fingerprint identity validation then includes unlocked by fingerprint, fingerprint and checks card and fingerprint body
Part identification etc..
Although it is very little to run into fingerprint identical example in practice so that carry out fingerprint login, fingerprint using fingerprint
The safety coefficient such as payment and fingerprint identity validation is high, but, undeniable to be, the fingerprint of two people is identical to be also possible to
, also, in the existing stage, fingerprint is identified by what software was carried out, when the identification of fingerprint is carried out by software, then leads
If seeing the similarity of the fingerprint texture for subsequently being recognized and the fingerprint texture for previously prestoring, when similarity reaches preset value,
Software then differentiates fingerprint recognition success, because software is when fingerprint recognition is carried out, simply differentiates the similarity of fingerprint texture, and in Pang
In big fingerprint database, then the similar fingerprint that similarity reaches preset value is had unavoidably, so, entered by a fingerprint
Row fingerprint is logged in, fingerprint pays and fingerprint identity validation, then do not have good security and reliability still.
And it is well known that before fingerprint login, fingerprint payment and fingerprint identity validation is carried out using fingerprint, it is necessary to it is pre-
Extraction is first acquired to fingerprint, therefore, the collection of fingerprint is extracted, then be that subsequent fingerprint is logged in, fingerprint pays and Fingerprint Identity
The prerequisite necessary condition of certification, the finger print data for gathering extraction is more complicated, subsequently carries out fingerprint login, fingerprint branch using fingerprint
Pay and the safety coefficient of fingerprint identity validation is higher.
So, design a kind of method and system that many fingerprints are synchronously extracted by mobile phone camera, then it is that have very much must
Want.
The content of the invention
It is an object of the invention to overcome above-mentioned prior art deficiency and provide a kind of many fingerprints of mobile phone camera it is same
Step extracting method and system.
The present invention solves the technical scheme that is used of prior art problem：
A kind of many fingerprint sync extracting methods of mobile phone camera, it is comprised the following steps：
S1, transmission fingerprint shoot request；
S2, fingerprint shoot；
S21, by the forefinger of the same hand, middle finger, the third finger and pinkie at least two fingers be aligned cell-phone camera
Head, and it is displayed on mobile phone display screen；
S22, reference mobile phone display screen, by the clear fingerprint image of mobile phone camera synchronization catch finger at least described in two
Picture；
S23, caught when the fingerprint image definition of finger reaches preset value at least described in two, it is automatic by mobile phone
Screen locking is simultaneously automatically performed the shooting of the fingerprint image of finger at least described in two；
S3, fingerprint picture processing；The fingerprint of finger at least described in two in captured fingerprint image is processed, with
Corresponding fingerprint texture is obtained, and intercepts the fingerprint picture containing corresponding fingerprint texture；
S4, fingerprint picture confirm；By by the fingerprint picture after fingerprint picture processing with to be preset with fingerprint clear scale accurate
Fingerprint reference picture contrasted, the fingerprint picture for being up to default resolution standard confirms as qualified fingerprint picture.
Above technical scheme is further elaborated below：
Preferably, step S21 also includes；The distance between finger and mobile phone are adjusted manually, so that finger at least described in two
The finger part almost all containing fingerprint be displayed on mobile phone display screen.
Preferably, step S5 is also included after step S4；
S5, fingerprint picture application；Including qualified fingerprint picture transfer to the external intelligence being connected with mobile phone signal is set
Need to carry out fingerprint in the APP for use fingerprint picture in standby and in mobile phone to put on record and use.
Preferably, in step S5, fingerprint picture application includes that fingerprint is logged in, fingerprint pays and fingerprint identity validation.
A kind of many fingerprint sync extraction systems of mobile phone camera, it includes：
Fingerprint shoots request module；The fingerprint shoots request module and is used to send fingerprint shooting request；
Fingerprint taking module；The fingerprint taking module is used to receive the fingerprint transmitted by the fingerprint shooting request module
Shooting is asked, and completes the fingerprint image of at least two fingers in the forefinger, middle finger, the third finger and pinkie of the same hand
Sync pulse jamming；
Fingerprint picture processing module；The fingerprint picture processing module is used in the fingerprint image to institute's sync pulse jamming extremely
The fingerprint of finger is processed described in few two, to obtain corresponding fingerprint texture, and intercepts the fingerprint containing corresponding fingerprint texture
Picture；
Fingerprint picture confirms module；The fingerprint picture confirms that module is used to by the fingerprint image after fingerprint picture processing
The piece fingerprint reference picture accurate with fingerprint clear scale is preset with is contrasted, and is up to the fingerprint picture of default resolution standard
Confirm as qualified fingerprint picture.
Above technical scheme is further elaborated below：
Preferably, it also includes：
