Information.
Next, by being specifically described for a kind of papers-scanning method combination attached drawing that specification embodiment provides:
Fig. 2 is a kind of flow diagram for papers-scanning method that this specification embodiment provides.For program angle,
The executing subject of process can be to be equipped on the program or application client of application server.
As shown in Fig. 2, the process may comprise steps of:
Step 202: obtaining the first image of multiframe being scanned with the first scanning angle to certificate, obtain the first figure
Image set, the scanning angle are the angle where plane where scanning lens and the certificate between plane.
Certificate can refer to for proving the certificates such as user identity, experience and file, such as:: resident identification card, the card such as passport
Part.
When carrying out papers-scanning identification, papers-scanning mode can be opened, such as: it is opened by the application program of installation
There is papers-scanning interface in camera function.Scanning angle mentioned herein can be understood as
Angle where plane where camera and certificate between plane.
When shooting direct picture, scan to obtain the first image of front scan with the first scanning angle.First scan angle
Degree can indicate front scan certificate image, and in practical applications, the first scanning angle can indicate flat where scanning lens
Smaller the first image to obtain front scan certificate of angle where face and certificate between plane.First scanning angle can be with table
Show an angle value, can also indicate an angular range.Such as: the first scanning angle is 10 ° or the first scanning angle is
0°-20°。
It should be noted that the first image mentioned in above-mentioned steps does not imply that the front and back sides of certificate, also refer to
The certificate image that front scan obtains, it is understood that are as follows: the first image is that plane where camera is kept as far as possible and swept
Retouch the image that plane where certificate is parallel or less parallel is scanned.
Step 204: obtaining the second image of multiframe for being scanned with the second scanning angle to the certificate, obtain the
Two image sets, second scanning angle are greater than first scanning angle.
Side image also refers to scanning lens and is tilted a certain angle the image that scanning obtains.Therefore, the second scan angle
Degree can be greater than the first scanning angle.Such as: the first scanning angle can be set to 0 ° -20 ° and (be more than or equal to 0 °, be less than
20 °), 20 ° -90 ° are set by the second scanning angle.
Step 206: determining the similarity between the first image collection and second image set.

With multinomial printing anti-counterfeiting technology.Such as: in gender item destination locations on resident identification card, there is " Great Wall " figure of orientation phototropic
Case, " Chinese CHINA " printed words for thering is light darkening to store under photograph；If certificate front is placed under ultraviolet light, Huo Zheqing
When obliquely view, it can be found that " Great Wall " pattern of fluorescent printing.Certificate had under different light different gloss and
Information, the certificate image scanned from different angles will not be identical.
In addition, when determining the similarity between front elevation image set and side view image set certificate can be being extracted just using CNN
The feature vector in face and side, then alignment similarity.Similarity-rough set can also be carried out using other algorithms, specifically calculate phase
Like degree method in this programme without limitation.
Step 208: judging whether the similarity is less than preset threshold, obtain the first judging result.
Due to the particularity of certificate, anti false film, the warning chip of document surface are under different directional rays or different
The image that angle scanning obtains can be different, wherein anti false film can be a kind of directional light color-changing membrane, therefore, in practical application
In, the first image of the front scan of true certificate and the second image of dip sweeping have difference.

Step 210: when first judging result indicates that the similarity is less than preset threshold, display the first prompt letter
Breath, first prompt information is for prompting the certificate to pass through fake certification.
If similarity is higher than preset threshold, it is believed that the front scan image of scanned certificate and the side of dip sweeping
Face image it is essentially identical (such as: can't see " Great Wall " pattern of fluorescent printing when identity card front scan, swept after tilt angle
Can't see the pattern on anti false film in the corresponding different images of the different angle retouched, then illustrate that the certificate is false papers), this
When, it is believed that scanned certificate is false papers.Conversely, when similarity value is less than preset threshold, it is believed that scanned card
Part is true certificate.
When it is true certificate that the result that scanning obtains, which is certificate, show for prompting certificate described in user to pass through fake certification
Or the information that scanning is completed.
It should be appreciated that application architecture dispositions method part step described in this specification one or more embodiment
Sequence can be exchanged with each other according to actual needs or part steps therein also can be omitted or delete.
It should be noted that needing to judge quilt according to two image sets after obtaining the first image set and the second image set
The true and false of certificate is scanned, at this point, in addition to being mentioned in the above method by calculating the similarity between two image sets, and compare
The size of similarity and preset threshold determines except the certificate true and false, can also be for the first image set and the second image obtained
Collection carries out integrated treatment using other recognition methods, judges the true and false of certificate, such as: use character recognition method, icon-based programming
Method, pixel recognition methods etc..This is not construed as limiting in this programme.
Method in Fig. 2 passes through the card for when scanning the image of certificate, guaranteeing to obtain front scan with the first scanning angle
First image of part scans the second image for obtaining the certificate of dip sweeping with second, does not need four sides of alignment to obtain scanning
Image, image could be obtained by avoiding the need for for the four edges of certificate being aligned with the frame at surface sweeping interface, and alignment procedure is many and diverse
