And if the characters of the first crown word number and the second crown word number are consistent, the recognition of the first crown word number and the second crown word number has almost no error, and the recognition result is accurate.
In this embodiment, if the characters of the first crown number and the second crown number are not identical, it is indicated that an error exists in the recognition process of at least one of the first crown number and the second crown number. And when the characters of the first crown number and the second crown number are inconsistent, judging whether the number of the characters of the first crown number and the second crown number which are inconsistent is larger than a preset threshold value. The specific preset threshold is 1-5, preferably 2.
And 143, if the number of the characters with the inconsistent first crown word number and the second crown word number is not larger than a preset threshold value, correcting the first crown word number and/or the second crown word number to obtain a target crown word number of the paper money.
In this embodiment, when the number of characters with inconsistent first and second crown numbers is not greater than the preset threshold, error correction is performed on the inconsistent characters. Specifically, a first character image of a character in the first crown word number, which is inconsistent with the second crown word number, is compared with a character template of the standard crown word number to obtain a first similarity result, a second character image of a character in the second crown word number, which is inconsistent with the first crown word number, is compared with the character template of the standard crown word number to obtain a second similarity result, and the first similarity result and the second similarity result are compared to confirm the target crown word number.
Illustratively, if the first crown word number is not consistent with the first character of the second crown word number, the recognition result of the first character of the first crown word number is 0, the recognition result of the second character of the first crown word number is 8, the first character image is compared with the template of the character 0 of the standard character template to obtain the similarity of 99%, the second character image is compared with the template of the character 8 of the standard character template to obtain the similarity of 60%, it indicates that 8 in the second character image is likely to be recognized as the number 8 by mistake during recognition because there is a dirty in the middle of the character 0, and therefore the first character of the target crown word number should be 0, the character with the similarity higher than that of the character template is taken as the character of the target crown word number, namely 0 is taken as the first character of the target crown word number, since the other characters are completely identical, the other characters can be directly mapped to the character marked as the target crown number in order.
In an alternative embodiment, in step 142, after determining whether the number of characters with the first crown number and the second crown number being inconsistent is greater than a preset threshold, the method further includes:
and 144, if the number of the characters with the inconsistent first crown word numbers and the second crown word numbers is larger than a preset threshold value, prompting that the paper money is abnormal.

Exemplarily, the euro is that the number of characters on both sides is different, i.e. the number of the prefix numbers on one side is different from that on the other side, wherein the prefix number on one side is only a part of the prefix number on the other side; coins are different sets of codes to which the two side crown numbers belong.
In this alternative embodiment, if the banknote is a banknote with a crown word number on both sides and the attributes of the crown word number on both sides are different, the obtaining the target crown word number of the banknote according to the first crown word number and the second crown word number in step 350 further includes:
and converting the first crown word number or the second crown word number to obtain the first crown word number and the second crown word number with the same attribute, and obtaining the target crown word number of the paper money according to the first crown word number and the second crown word number with the same attribute.
In this alternative embodiment, when the crown word numbers of the crown word numbers on both sides are not identical, the correspondence rule of the crown word numbers on both sides can be obtained according to the banknote information, the first crown word number is converted into the attribute identical to the second crown word number according to the correspondence rule, or the second crown word number is converted into the attribute identical to the first crown word number according to the correspondence rule, and after the conversion, the first crown word number and the second crown word number having the identical attribute can be obtained.
Illustratively, when the current banknote is euro, the first crown number has fewer characters than the second crown number, the first crown number has only the last six digits, and the second crown number has twelve complete digits, the first six digits of the second crown number are supplemented in front of the first crown number, so that the first crown number with the same attribute as the second crown number can be obtained.
For example, when the first crown number and the second crown number have different character types, if the first crown number is the first character and the second crown number is the second character, the first crown number is converted into the second character to obtain the first crown number with the same attribute as the second crown number.
After a first crown number and a second crown number with the same attribute are obtained, whether the characters of the first crown number and the second crown number are consistent or not is judged. And if the characters of the first crown word number and the second crown word number are consistent, confirming the first crown word number or the second crown word number as a target crown word number. If the characters of the first crown word number and the second crown word number are not consistent; then judging whether the number of the characters with the inconsistent first crown word number and the second crown word number is larger than a preset threshold value or not; and if the number of the characters with the inconsistent first crown word number and the second crown word number is not larger than a preset threshold value, correcting the first crown word number and/or the second crown word number to obtain a target crown word number of the paper money. And if the number of the characters with the inconsistent first crown word number and the second crown word number is larger than a preset threshold value, prompting that the paper money is abnormal.
According to the technical scheme of the embodiment, the first crown word number or the second crown word number is converted to obtain the first crown word number and the second crown word number which have the same attribute, and the target crown word number of the paper money is obtained according to the first crown word number and the second crown word number which have the same attribute, so that the problem of identifying crown word numbers with different attributes on two sides is solved, the effect of identifying crown word numbers with different attributes on two sides is achieved, and the identification accuracy of crown word numbers with different attributes on two sides is improved.
