Background
After the OCR engine scans the identity card, the identity card information is identified so as to provide data for subsequent business processing. Since the recognition accuracy of the OCR engine cannot reach 100%, after the OCR engine recognizes the identification card information, the identification card information needs to be corrected to improve the accuracy of the identification card information. The identity card address is generally corrected through empirical values, for example, characters "mansion" and "" are particularly similar and are easy to be confused, and the "mansion city" is easy to be recognized as " city" by an OCR recognition engine. Since addresses generally only appear in "Xiamen", the "Xiamen" is used directly in the correction process to replace "". The method for directly replacing and correcting has limited correcting quantity and is easy to cause excessive replacement due to over subjectivity in practical algorithm application, and the corrected information has low accuracy.

The identity card number is generated randomly by a program and is an identity card number in an unrealistic identity.
S2, verifying the accuracy of the ID card number to obtain a verification result; the verification results include accurate and inaccurate.
Wherein, the accuracy of the ID card number is judged according to the 5.1.4.1 validation formula and the calculation of 5.1.4.2 validation code character set in GB11643-1999 citizen ID number.
And S3, if the verification result is accurate, acquiring three-level address information corresponding to the first six bits of the identification number.
And only when the verification result of the ID card number is accurate, the ID card address is corrected according to the first six digits of the ID card number. The first six digits of the ID card number are address codes, and the address codes are administrative division codes of the county (city and district) where the encoding object house entrance is located.
S4, acquiring three-level address information corresponding to the first six digits of the ID card number from a preset address mapping table; the third-level address information comprises provincial-level address information, city-level address information and county-level address information; each record in the address mapping table comprises a two-digit code and address information corresponding to the two-digit code.
For example, the first six digits of the id number "360222198610060711" are "360222", where "36" represents provincial-level address information "Jiangxi province", "02" represents city-level address information "Jingdezhen city", and "22" represents county-level address information "Floating Beam county".
S5, correcting the first part of the ID card address according to the three-level address information; the identity card address comprises a first part and a second part; the first part comprises provincial, city and county addresses; the second part is the address information of the identity card address except the first part. The method specifically comprises the following steps:
s51, judging whether the county level address information in the three-level address information exists in the ID card address.
For example, the id card address "wanxi province shadow town city floating beam county through public bridge town doodle group 136" is traversed, and county-level address information "floating beam county" corresponding to the id card number "360222198610060711" exists in the id card address.
S52, when the county level address information in the three levels of address information exists in the ID card address, correcting the first part of the ID card address according to the provincial level address information and the city level address information in the three levels of address information.
In order to avoid inconsistency between an identity card address and an address corresponding to an identity card number due to the fact that some identity card addresses are changed to sign a user port address, in the embodiment, whether county-level address information corresponding to the identity card number exists in the identity card address recognized by the OCR engine is searched, and if the county-level address information exists, the county-level address of the identity card number is consistent with the identity card address obtained through recognition, so that the provincial-level address and the city-level address corresponding to the identity card number are also consistent. Therefore, the address of the identity card obtained by the OCR engine can be corrected through the provincial address and the urban address corresponding to the identity card number.
Preferably, the correcting the first part of the id card address according to the provincial address information and the urban address information in the three-level address information specifically includes:
s521, obtaining the position information of the character province in the ID card address to obtain the province address ending position.
S522, setting the position of the first character of the ID card address as the provincial address starting position.
For example, the location of the "wane" character in the identification card address "wane west shadow town city floating beam county city via public bridge town doody group 136" is the provincial address starting location.
And S523, replacing characters from the start position of the provincial address to the end position of the provincial address by using the provincial address information in the three-level address information.
For example, the character from the provincial address start position to the provincial address end position is "wangxi province", and the provincial address information in the three-level address information corresponding to the identification number is "jiangxi province". Therefore, the provincial address of the identification card address recognized by the OCR engine is 'Wangxi province' with an error, and the 'Wangxi province' needs to be replaced by 'Jiangxi province' so as to correct the recognition result of the OCR engine.
And S524, setting the position information of the last character of the provincial level address ending position in the ID card address as the city level address starting position.
For example, in the id card address "wanxi province shadow town city floating beam prefecture through public bridge town doodle joe group 136", the position of the "province" character is the province level address ending position, and the position of the "scenery" character is the city level address starting position.

For example, in the identification card address "wanxi province shadow town city floating beam county city dobby joe group 136 via public bridge town dobby," floating "character is located as the county-level address starting position.
S526, setting the position information of the previous character of the county-level address starting position in the identity card address as the city-level address ending position.
For example, in the identification card address "wanxi province shadow town city floating beam county city doodle group 136 via public bridge town doodle village," city "character is located at the city level address ending position.
S527, replacing the characters from the start position of the city level address to the end position of the city level address with the city level address information in the three levels of address information.
For example, the character from the start position of the civic address to the end position of the civic address is "jing de zhen", and the civic address information in the third-level address information corresponding to the identification number is "jing de zhen". Therefore, the identity card address recognized by the OCR engine has an error in the "madder town" and needs to be replaced by the "madder town" to correct the recognition result of the OCR engine.
S6, correcting the second part of the ID card address according to a preset address information base; the address information base comprises a plurality of pieces of correct address information; the address information in the address information base comprises village and town address information, village address information and street address information.
Wherein the second portion of the identification card address can be corrected using existing identification card address correction methods.
Preferably, the similarity between the second part of the ID card address and each address information in the address information base is calculated; and replacing the second part of the ID card address with the address information with the maximum similarity in the address information base.
For example, in this embodiment, the second part of the address of the identity card is "number 136 of the crow group of the crow of the public bridge town," a large amount of address information which does not include the provincial address, the city address and the county address is stored in the preset address information base, and the address information with the maximum similarity in the preset address information base is "number 136 of the crow group of the crow of the public bridge town. Thus, the second portion of the identification card address "bridge number 136 via bridge town doodle bridge number 136" is replaced with "bridge number 136 via bridge town doodle bridge number via bridge town doodle bridge".
The identity card address obtained by the OCR engine identification is corrected through the steps, and the finally obtained identity card address is 136 number of the crow bridge group of the city of the Town bridge, Jingdezhen, Xia, the city of the floating girder, the city of the public bridge, the town, the crow bridge and the village.
In this embodiment, the first six digits of the identification card number are used to correct the identification card address obtained by OCR recognition. Since the first bit to the second bit of the identification card number are codes of provincial level address information, the third bit to the fourth bit are codes of city level address information, and the fifth bit to the sixth bit are codes of county level address information, the first six bits of the identification card number can be used for directly and effectively correcting provincial level address information, city level address information and county level address information in the identification card address, and the parts except the provincial level address information, the city level address information and the county level address information in the identification card address are compared with the addresses in the address information base to achieve the purpose of correction. In the embodiment, the provincial level address information, the municipal level address information and the county level address information in the identity card address are corrected by utilizing the first six digits of the identity card number, so that the times of calling an address information base for comparison in the process of correcting the identity card address obtained by OCR recognition are effectively reduced, and the time for correcting the identity card address is greatly shortened. Meanwhile, the address information base does not need to store provincial level address information, city level address information and county level address information, the capacity of the address information base can be reduced, and the time for correcting the ID card address by comparing the ID card address with the address in the address information base is further shortened.

Preferably, the similarity between the second part of the ID card address and each address information in the address information base is calculated; and replacing the second part of the ID card address with the address information with the maximum similarity in the address information base.
For example, in this embodiment, the second part of the address of the identity card is "number 136 of the crow group of the crow of the public bridge town," a large amount of address information which does not include the provincial address, the city address and the county address is stored in the preset address information base, and the address information with the maximum similarity in the preset address information base is "number 136 of the crow group of the crow of the public bridge town. Thus, the second portion of the identification card address "bridge number 136 via bridge town doodle bridge number 136" is replaced with "bridge number 136 via bridge town doodle bridge number via bridge town doodle bridge".
The identity card address obtained by the OCR engine identification is corrected through the steps, and the finally obtained identity card address is 136 number of the crow bridge group of the city of the Town bridge, Jingdezhen, Xia, the city of the floating girder, the city of the public bridge, the town, the crow bridge and the village.
In this embodiment, the first six digits of the identification card number are used to correct the identification card address obtained by OCR recognition. Since the first bit to the second bit of the identification card number are codes of provincial level address information, the third bit to the fourth bit are codes of city level address information, and the fifth bit to the sixth bit are codes of county level address information, the first six bits of the identification card number can be used for directly and effectively correcting provincial level address information, city level address information and county level address information in the identification card address, and the parts except the provincial level address information, the city level address information and the county level address information in the identification card address are compared with the addresses in the address information base to achieve the purpose of correction. In the embodiment, the provincial level address information, the municipal level address information and the county level address information in the identity card address are corrected by utilizing the first six digits of the identity card number, so that the times of calling an address information base for comparison in the process of correcting the identity card address obtained by OCR recognition are effectively reduced, and the time for correcting the identity card address is greatly shortened. Meanwhile, the address information base does not need to store provincial level address information, city level address information and county level address information, the capacity of the address information base can be reduced, and the time for correcting the ID card address by comparing the ID card address with the address in the address information base is further shortened.
And S7, calling an OCR engine to identify the gender of the identity card to obtain a gender identification result.
S8, judging the parity of the 15 th bit to the 17 th bit of the ID number to obtain a judgment result; the judgment result comprises an odd number and an even number.
S9, if the judgment result is odd, correcting the sex identification result to be male; otherwise, correcting the gender identification result to be female.
Wherein, the 15 th to 17 th of the ID number are sequence codes, the sequence code for male is odd, and the sequence code for female is even. Accordingly, the gender recognition result by the OCR engine can be corrected according to the parity of the sequential code.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
