Abstract
The invention discloses a method for automatically distinguishing a first-generation identity card from a second-generation identity card, which comprises the following steps of: obtaining an identity card image; analyzing and recognizing characters in the appointed image; judging whether the recognized characters have 15 just continuous figures or not; if so, returning the identity card type as the first generation identity card; if not, judging whether the recognized characters have a character string of citizenship number; if so, returning the identity card type as the second generation identity card, if not, judging whether the recognized characters have a character string of number; and if so, returning the identity card type as the first generation identity card. The method for automatically distinguishing the first-generation identity card from the second-generation identity card is used for automatically distinguishing whether the identity card is the first generation or the second generation according to the identity card image shot or scanned by a scanner, and improves the convenience for using and authenticating the identity card.
Description
Technical field
The invention belongs to the character recognition technology field, relate to a kind of I.D. recognition methods, relate in particular to the method for a kind of automatic distinguishing first generation and second generation I.D..
Background technology
As the unique identification of personal identification, I.D. is the certificate that people often will use.Though at present domestic large tracts of land has been used second generation I.D., according to law, first generation I.D. still can legally use before the deadline, and this just means that can there be a very long time simultaneously in first generation I.D. and second generation I.D., and is expired up to all first generation I.D.s.
One of common use-pattern of I.D. is by scanner scanning or takes pictures and obtain the picture of I.D., utilize image processing techniques and optical character identification (OCR then, Optical Character Recognition) technology identifies Word message wherein, comprise identification card number, name etc., and then the related web site that this identification card number and name send to the Ministry of Public Security got on to inquire about, see with the website on record whether conform to, judge the true and false of I.D. with this.In this was used, the accuracy rate of identification card number and name identification was very important, otherwise will strengthen the burden of artificial correction identification error.
First generation I.D. and second generation I.D. are at typesetting format, all there is very big difference font or the like aspect, if can know earlier that the certificate in the picture of being discerned is first generation I.D. or second generation I.D., and then literal wherein discerned, can improve the accuracy rate of identification greatly.
And in the existing scheme, also do not have can subregion two generation ID types method.
Summary of the invention
Technical matters to be solved by this invention is: the method for a kind of automatic distinguishing first generation and second generation I.D. is provided, can improves the efficient that I.D. uses and authenticates.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
The method of a kind of automatic distinguishing first generation and second generation I.D., described method comprises the steps:
The literal in the specified image is analyzed and discerned to step 102;
Whether step 103 exists just continuous 15 numeral in the literal that identifies; If answer forwards step 107 to for being, otherwise forward step 104 to;
Whether step 104 exists character string " citizenship number " in the literal that identifies; If answer forwards step 108 to for being, otherwise forward step 105 to;
Whether step 105 exists character string " numbering " in the literal that identifies; If answer forwards step 107 to for being, otherwise forward step 106 to;
Step 109 finishes.
As a preferred embodiment of the present invention, in the described step 101, take or scanner scanning is obtained the I.D. image by image unit, perhaps duplicate to obtain by memory carrier; Perhaps need not to take, only obtain the I.D. image of preview by image unit; In the described step 102, analyze and discern the literal in the specified image-region, search the literal in the image-region, and utilize the OCR technology to discern.
As a preferred embodiment of the present invention, in the described step 103, whether there is just continuous 15 numeral in the literal that identifies; So-called just continuous 15 numeral is meant does not have continuous 16 or the numeral of multidigit more, thereby is confirmed to be first generation I.D..
As a preferred embodiment of the present invention, in the described step 106, described I.D. image is carried out people's face to be detected, in image, detect the size and the position of people's face, the result who detects according to people's face judges the I.D. type, and specific practice comprises: image is carried out people's face detect, if do not detect people's face, then return failure, can't judge type of credential; If detect people's face on the image left side, then returning type of credential is first generation I.D., if detect people's face on image the right, then returning type of credential is second generation I.D..
Beneficial effect of the present invention is: the automatic distinguishing first generation that the present invention proposes and the method for second generation I.D., to scanner scanning or take pictures that to obtain I.D. picture automatic distinguishing certificate be first generation I.D. or second generation I.D.; This method has improved the convenience that I.D. uses and authenticates.
