Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for generating a certificate photo in some embodiments of the present application. The certificate photo generation method is used in self-service certificate handling equipment. The certificate photo generation method comprises the following steps:
s101, acquiring an identity card number, fingerprint information and a face image of a user to be authenticated, which are acquired in real time;
s102, acquiring reference fingerprint information of the user to be authenticated based on the identity card number;
s103, judging whether the user to be authenticated is the user or not according to the fingerprint information and the reference fingerprint information;
s104, acquiring a first standard photo which is uploaded by a user and accords with a dressing standard of a certificate photo;
s105, judging whether the first standard photo and the face image are the same person or not according to the first standard photo and the face image;
and S106, if the first standard photo is the same person, processing the first standard photo to obtain a standard certificate photo.
In this step S101, the identification number may be obtained based on a manual input by the user. The fingerprint information is acquired by a fingerprint collector arranged on the self-service certificate handling equipment. The face image is a positive high-definition face image of the user collected by a high-definition camera of the self-service certificate handling equipment.
In step S102, the reference fingerprint information is the fingerprint information that the user entered during the last transaction, and since the fingerprint of the person is not changed, the fingerprint information can be used as a determination condition for determining whether the transactor is the person.
In step S103, if the fingerprint information is the same as the reference fingerprint information, it indicates that the transacted certificate is the principal, and if not, the transacted certificate is not the principal.
In step S104, the toilet dressing standard of the identification photo is a rule issued by the certificate authority, for example, the nose ring cannot be worn, the hair cannot block five sense organs, the beauty pupil cannot be worn, the sunglasses cannot be worn, the hair style cannot be too high, and the like, and the relevant rules can be specifically checked. Of course, a pre-established and trained neural network model may be used to determine compliance.
In step S105, a face matching algorithm commonly used in the prior art may be used to calculate a matching degree between the face in the first standard photo and the face image, and only when the matching degree is higher than a set threshold, it can be determined that the face in the first standard photo and the face image are the same person.
In step S106, if the person is the same person, the first standard photo is processed to obtain a standard identification photo, for example, background switching, image cropping, zooming, and the like are performed.
In some embodiments, as shown in fig. 2, this step S106 may include the following sub-steps: s1061, extracting the human body image of the user to be certified from the first standard photo; s1062, cutting and zooming the human body image to obtain a target human body image meeting the certificate handling requirements; s1063, calling a corresponding background image based on the certificate handling requirement, and combining the background image and the target human body image into a standard certificate photo. In step S1061, a background segmentation algorithm or a common automatic matting algorithm in the prior art may be used to obtain the human body image of the user. In step S1062, body parts other than the body part required for id card transaction are trimmed, and the size of the image is adjusted to the size prescribed for id card transaction. Specifically, in some embodiments, the human body image is cut to obtain a first image of a human body part meeting the requirement of certificate handling; and zooming the first image to obtain a target human body image meeting the requirement of the certificate handling size. In step S1063, different certificates correspond to different background images. When synthesizing, the standard certificate photo can be obtained by adopting an image synthesis algorithm in the prior art.
In some embodiments, this step S105 may include the steps of: s1051, carrying out face matching on the first standard photo and the face image to obtain similarity; s1052, if the similarity is larger than a preset threshold value, judging that the first standard photo and the face image are the same person. The preset threshold value is an empirical value obtained through multiple tests, so that the obtained first standard photo is guaranteed to be a user to be authenticated, and the representation force of the first standard photo is improved.
In some embodiments, as shown in fig. 3, this step S101 may include the steps of: s1011, acquiring a plurality of pre-prepared standard photos uploaded by a user, wherein the standard photos are obtained by shooting the user in advance according to a certificate handling, dressing and dressing requirement; s1012, identifying the standard photos to obtain a plurality of second standard photos meeting the certified dressing and making up requirements in each standard photo; and S1013, selecting one of the second standard photos as a first standard photo.
In step S1011, since the user' S own judgment of the standard may have a deviation, some more standard photos may be prepared, so as to avoid the situation that all of the standard photos do not meet the requirements during the transaction. The standard photo has no requirement on the background, only has a requirement on the dressing and the dressing of the user, and needs the user to perform the dressing and the dressing as much as possible according to the dressing and the dressing requirements.
In step S1012, a pre-trained neural network model is produced according to the dressing requirement, and a second standard photo meeting the dressing requirement is selected from the plurality of standard photos through the neural network model. And the quality of the screened second standard photo is improved by screening through the neural network model.
In this step 1013, there are many selection criteria, for example, a second standard photo with the highest pixel degree with the currently captured face image may be selected as the first standard photo, so as to improve the recognition degree or the recognition degree of the standard certificate photo.
In some embodiments, this step S1013 may include the steps of: calculating the similarity between each second standard photo and the face image; and taking the second standard photo with the maximum similarity as the first standard photo.
In some embodiments, this step S1013 may include the steps of: calculating the pixel color degree of each second standard picture; and taking the second standard photo with the largest degree of plain color as the first standard photo. The degree of pigment is used for evaluating the degree of makeup failure, and can be calculated by adopting a pre-trained neural network model.
As can be seen from the above, the certificate photo generation method provided in the embodiment of the present application obtains the identity card number, the fingerprint information, and the face image of the user to be authenticated, which are acquired in real time, by the certificate photo generation method; acquiring reference fingerprint information of the user to be authenticated based on the identity card number; judging whether the user to be authenticated is the user or not according to the fingerprint information and the reference fingerprint information; acquiring a first standard photo which is uploaded by a user and accords with a dressing standard of a certificate photo; judging whether the first standard photo and the face image are the same person or not according to the first standard photo and the face image; if the first standard photo is the same person, processing the first standard photo to obtain a standard certificate photo; thereby realize the generation of standard certificate photo, make the user can need not to make up specially and make up the collection that comes the self-service certificate handling equipment department of outside to carry out standard certificate photo, and because it has introduced fingerprint identification and face identification, the people that both can avoid the official to correspond with the identity card number is not same alone, also prevented the problem of identity falsely, the photo that also can avoid handling the certificate is not same people with the person of handling the certificate, the possibility of falsely using other people's photo to handle the certificate has been avoided, not only can improve the convenience of handling the certificate, can also guarantee the degree of accuracy of the information of identity card, can prevent that the identity from being falsely used, also can prevent to come counterfeit other people through counterfeit photo.

Wherein, the identification number can be obtained based on the manual input of the user. The fingerprint information is acquired by a fingerprint collector arranged on the self-service certificate handling equipment. The face image is a positive high-definition face image of the user collected by a high-definition camera of the self-service certificate handling equipment.
The reference fingerprint information is the fingerprint information which is input by the user during the last certificate handling, and because the fingerprint of the person is not changed, the fingerprint information can be used as a judgment condition for judging whether the certificate handling person is the person.
If the fingerprint information is the same as the reference fingerprint information, the certificate transacted is the principal, otherwise, the certificate transacted is not the principal.
The dressing and dressing standard of the certificate photo is a rule issued by a certificate authority, for example, the certificate photo can not be worn with a nose ring, the hair can not shield five sense organs, the certificate photo can not be worn with a pupil, the certificate photo can not be provided with sunglasses, the hair style can not be too high, and related regulations can be checked. Of course, a pre-established and trained neural network model may be used to determine compliance.
The matching degree between the face in the first standard photo and the face image can be calculated by adopting a commonly used face matching algorithm in the prior art, and the face in the first standard photo and the face image can be judged to be the same person only when the matching degree is higher than a set threshold value.
