Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
A kind of invoice provided in an embodiment of the present invention knows method for distinguishing, shown in Figure 1, comprising:
Step 101: obtaining the invoice image of target invoice.
In the embodiment of the present invention, target invoice is the invoice for needing to identify verifying, that is, needs to verify the true of the target invoice
It is pseudo-.Specifically, the invoice image of target invoice can be obtained by way of scanning；Alternatively, if the target invoice is electronics hair
Ticket, can be by the corresponding image of electronic invoice directly as invoice image.
Step 102: the invoice information in identification invoice image, invoice information includes invoice field and opposite with invoice field
The invoice data answered.
In the embodiment of the present invention, after getting invoice image, that is, invoice field and the phase in invoice image may recognize that
The invoice data answered identifies the invoice information in invoice image.Wherein it is possible to identify invoice based on image recognition technology
Invoice information in image, for example it is based on OCR (Optical Character Recognition, optical character identification) technology
Deng.
In the embodiment of the present invention, invoice field includes that invoice codes, invoice number, date of making out an invoice, amount issued (are free of
Tax), check code, purchaser's title, purchaser's Taxpayer Identification Number, seller title, in seller Taxpayer Identification Number etc.
One or more, invoice data is the corresponding data of invoice field.For example, " invoice number " that invoice field is 8, phase
Corresponding invoice data is " 12345678 ".
Step 103:, will according to the corresponding relationship between the textview field of invoice validation system and the invoice field of invoice information
Corresponding invoice data is input in the textview field of invoice validation system in invoice information, and obtains invoice validation system feedback
Verification result.
In the embodiment of the present invention, invoice validation system is the system or official's platform that can verify true from false of bills, such as state
Shui Ju official website etc..Textview field is the control of invoice validation system, the textview field in the present embodiment be specifically as follows uniline or
The Input of multirow.The corresponding invoice field of each textview field, for facilitating user to submit corresponding invoice data, into
And inquiry true from false of bills can be enabled a user to.In the embodiment of the present invention, after identifying invoice field and invoice data, if
It can determine the corresponding relationship between the textview field of the invoice validation system and invoice field, it can be by corresponding invoice data certainly
Dynamic filling verifies the target invoice by the invoice validation system into corresponding textview field, and available to hair
The verification result of ticket verifying system feedback.If the invoice data submitted automatically is correctly, invoice validation system feeds back the mesh
Mark invoice is the verification result of legalized invoice；Conversely, invoice validation system feeds back the verifying knot that the target invoice is illegal invoice
Fruit.
Optionally, due to that can include much information in invoice, but invoice validation system be only needed when verifying true from false of bills
User is wanted to submit the partial information of invoice, therefore step 102 " the invoice letter in identification invoice image in the embodiment of the present invention
Breath " specifically includes:
Determine effective invoice field needed for invoice validation system；It identifies relevant to effective invoice field in invoice image
Invoice information, the invoice field in invoice information are effective invoice field.
In the embodiment of the present invention, effective invoice field is that invoice validation system verifies required field when true from false of bills,
When identifying invoice information in a step 102 at this time, it is only necessary to identify effective invoice field and corresponding invoice data.Example
Such as, invoice validation system needs user to provide three invoice fields when verifying invoice: invoice codes, invoice number and issuing gold
Volume, i.e., effective invoice field includes invoice codes, invoice number and amount issued, when identifying the invoice information of target invoice,
It only needs to identify invoice data corresponding with invoice codes, invoice number and amount issued.By determining effectively hair
Ticket field, it is possible to reduce the treating capacity of image recognition improves recognition efficiency.
A kind of invoice provided in an embodiment of the present invention knows method for distinguishing, can carry out automatic identification to invoice, and identify
Invoice data is filled into invoice validation system true to invoice by invoice field and invoice data in invoice image automatically later
Puppet carries out inquiring and authenticating, and the available verification result to invoice validation system feedback, true so as to automatically determine invoice
It is pseudo-.Which does not need manual verification, can largely save time and the cost of staff, improves the speed of verifying true from false of bills
Degree and efficiency.Meanwhile passing through the effective invoice field of determination, it is possible to reduce the treating capacity of image recognition improves recognition efficiency.
On the basis of the above embodiments, shown in Figure 2 in order to more accurately identify invoice information, on
Stating step 102 " invoice information in identification invoice image " includes:
Step 1021: all data undetermined in identification invoice image, according to the data format of data undetermined determine with to
Fixed number determines the corresponding one or more indefinite numbers of each invoice field according to corresponding one or more invoice fields respectively
According to.
Invoice data and corresponding invoice are determined in the embodiment of the present invention by way of identifying invoice data first
Field.Since the invoice data in invoice is usually to be made of number, i.e., " invoice data " in the present embodiment refers to wrapping
Data containing number；For example, the invoice data of corresponding " amount issued " is " 100.00 " or " $100.00 ", correspondence " issues day
The invoice data of phase " is " on January 1st, 2018 " or " 2018/1/1 " etc..Under normal circumstances, number is identified based on image recognition technology
Accuracy when word is higher, and in the present embodiment by way of identifying invoice data first, the accuracy of identification can be improved.
Specifically, the data undetermined are to wrap firstly the need of the data undetermined identified in invoice image in the present embodiment
Data containing number；Since the corresponding invoice data of invoice fields different in invoice generally has specific format, the present embodiment
The middle data format according to data undetermined can determine that the data undetermined may correspond to which or which invoice field, that is, can determine
The corresponding one or more invoice fields of data undetermined.Wherein, the data format of data undetermined refer to the data digit,
Intrinsic form of expression of data etc..For example, 12 invoice codes (invoice codes of VAT invoice before are 10), 8
The invoice number of position, " X X month X day " format, " X-X-X " format or " X/X/X " format are made out an invoice the date, " $XXX " format or
The amount issued etc. of " XX.XX member " format.For example, the number that invoice number is 8, phone (such as complaint telephone etc.) is also 8
The number of position, if some data undetermined is " 12345678 ", the data " 12345678 " undetermined and " invoice number " and " electricity
Words " are corresponding, i.e., " 12345678 " may be invoice number, it is also possible to phone.
It meanwhile as described above, between the data undetermined in the present embodiment and invoice field being one-to-one or one-to-many
Corresponding relationship, correspondingly, be also possible to one-to-one or one-to-many corresponding relationship between invoice field and data undetermined, i.e., one
Invoice field may correspond to a data undetermined, it is also possible to corresponding multiple data undetermined.For example, the data lattice with 8 bit digitals
The data undetermined of formula include " 12345678 " and " 87654321 ", corresponding two data undetermined of invoice field " invoice number "
" 12345678 " and " 87654321 ", i.e. invoice number may be 12345678, it is also possible to 87654321.
It should be noted that " data undetermined " and " invoice data " in the present embodiment be same data in different time points
Two address.Specifically, " data undetermined " refer to the data for most starting to identify from invoice image, do not know also at this time
Road should " data undetermined " which corresponding invoice field；And " invoice data " refers to knowing the data of which corresponding invoice field,
I.e. if it is known which invoice field is some data correspond to, then the data are known as " invoice data ".For example, being identified from invoice image
Data " 12345678 " out, then the data " 12345678 " are known as " data undetermined " at this time, if determining the corresponding " hair of the data later
This field of ticket number ", then the data " 12345678 " are known as " invoice data " at this time.
Step 1022: when the corresponding data undetermined of invoice field, using data undetermined as corresponding with invoice field
Invoice data.
Step 1023: when invoice field corresponds to multiple data undetermined, an indefinite number is chosen from multiple data undetermined
According to as effective data undetermined, and will effective data undetermined as invoice data corresponding with invoice field.
In the embodiment of the present invention, if invoice field and data undetermined are one-to-one relationships, can directly determine this to
Fixed number is according to as invoice data corresponding with invoice field.When invoice field corresponds to multiple data undetermined, can therefrom select
Take a data undetermined as invoice data corresponding with the invoice field.
Specifically, above-mentioned steps 1023 " choosing a data undetermined from multiple data undetermined as effective data undetermined "
Include:
Step A1: it will have determined that with the data undetermined of invoice field corresponding relationship labeled as identification state.
In the embodiment of the present invention, data undetermined for part can uniquely determine invoice corresponding with the data undetermined
Field, such data undetermined are " having determined that the data undetermined with invoice field corresponding relationship ", this thing can be by the indefinite number
According to labeled as identification state.Wherein, the data undetermined determined in step 1022 are " to have determined that and invoice field corresponding relationship
Data undetermined ".For example, the data format on date is issued as " xx xx month xx day " or " xx/xx/xx ", and invoice image
In only one data fit undetermined this issue the data format on date, then the data undetermined are the corresponding invoice of invoice image
Data, at this time can be by the data undetermined labeled as identification state.
Step A2: reject be in the corresponding multiple data undetermined of invoice field identification state data undetermined, and from surplus
A data undetermined are chosen in remaining data undetermined as effective data undetermined.
In the embodiment of the present invention, when invoice field corresponds to multiple data undetermined, if some or certain indefinite numbers therein
According to being identification state, then explanation has determined that the corresponding relationship of the data undetermined and other invoice fields, the i.e. indefinite number
According to certain uncorrelated to current invoice field, the data undetermined that such is identification state can be rejected at this time, from remaining
A data undetermined are chosen in data undetermined as effective data undetermined.Wherein, if after rejecting the data undetermined of identification state,
The invoice field is only corresponding with a remaining data undetermined, then remaining unique data undetermined are effective indefinite number
According to.By rejecting the data undetermined of identification state in the present embodiment, can be further improved when choosing effectively data undetermined
Accuracy.
Optionally, since invoice type is relatively more, such as common invoice, VAT invoice etc., and every kind of invoice there is also
A variety of groups, for example VAT invoice includes again: VAT invoice, value-added tax common invoice, the unified hair of motor vehicle sale
Ticket, used car sale uniform invoice, carrying trade VAT invoice etc., and there are also quota invoice, universal machines to dismiss ticket
Deng the nominal value size of every kind of invoice and typesetting are distinct, and it is tired to lead to identify that the invoice information in invoice image exists
It is difficult.In order to overcome the problems referred above, in the embodiment of the present invention, above-mentioned steps 1023 " choose an indefinite number from multiple data undetermined
According to as effective data undetermined " include:
Step B1: using the invoice field of the multiple data undetermined of correspondence as target invoice field, and target invoice word is determined
Position of the corresponding each data undetermined of section in invoice image.
Step B2: invoice text corresponding with target invoice field in identification invoice image, and determine that invoice text is being sent out
Position in ticket image.
In the embodiment of the present invention, if some invoice field corresponds to multiple data undetermined, in order to facilitate subsequent descriptions, by the hair
Ticket field is known as target invoice field.Meanwhile data undetermined are the data identified from invoice image, data undetermined are located at hair
Specific position in ticket image can also determine each data undetermined corresponding with the target invoice field in invoice image at this time
In position.For example, establishing two-dimensional coordinate system for invoice image, which can be described in the form of coordinate points at this time
Position, such as using the coordinate of the point in the data lower left corner undetermined as the position of the data undetermined, or by the data undetermined
Central point position of the coordinate as the data undetermined.
In addition, when identifying invoice information, identifying invoice data first in the embodiment before above-mentioned；Due to each
The invoice field that invoice includes is known, even identical, the invoice field in the invoice information identified in the present embodiment
It is the determination according to the invoice data identified, not by image recognition technology, Direct Recognition is come out from invoice image
's.Likewise, the target invoice field is not that Direct Recognition comes out from invoice image yet.But in the present embodiment,
It is which invoice field in order to which correctly determining invoice data is corresponding, based on the hair in image recognition technology identification invoice image
Ticket text, which is invoice field identify from invoice image, textual form, if the hair identified
Ticket text is corresponding with the target invoice field, it is determined that the position of the invoice text in invoice image.Wherein it is determined that invoice
Text is similar with the process of above-mentioned " determining position of the data undetermined in invoice image " in the position in invoice image, herein not
It repeats.
Step B3: according to invoice text in the position of position and each data undetermined in invoice image in invoice image
It sets, determines the spacing between invoice text and data undetermined respectively, spacing includes line space and/or column pitch.
Step B4: using data undetermined corresponding to the minimum spacing in all spacing as effective data undetermined.
Both in the embodiment of the present invention, according to the position of invoice text and data undetermined in invoice image, can determine
Line space or column pitch in invoice image.Specifically, a kind of form of expression of invoice image is shown in Figure 3, in Fig. 3 with
Invoice image includes four invoice texts and three data instance explanations undetermined.
In the embodiment of the present invention, the line space between invoice text and data undetermined refers to the position coordinates of invoice text
With the difference of the position coordinates of data undetermined on y direction；Correspondingly, the column pitch between invoice text and data undetermined
Difference of the position coordinates of the position coordinates and data undetermined that refer to invoice text in X direction.Line space is smaller, says
The bright invoice text and data undetermined more may be in same a line；Column pitch is smaller, which is more possible to data undetermined
In same row.As shown in figure 3, line space between invoice text a and data undetermined 1 is smaller, invoice text d and data 1 undetermined,
2, the column pitch between 3 is smaller.
If the line space or column pitch between invoice text and data undetermined are that the invoice text is relevant with other all
The smallest in spacing between data undetermined, then the line space or column pitch are minimum spacing, corresponding with the minimum spacing
Data undetermined and the invoice text are very likely located at same a line or same row, the corresponding data undetermined of the minimum spacing and the hair
Ticket text is corresponding relationship, at this time can will using data undetermined corresponding to the minimum spacing in all spacing as effectively
Data undetermined.As shown in figure 3, if the corresponding invoice text of target invoice field is invoice text a, with the target invoice field pair
The data undetermined answered include data 1 undetermined, data undetermined 2, data undetermined 3；Invoice text a and data 1 undetermined known at this time it
Between there is minimum spacing (minimum line space), at this time can be by data 1 undetermined as the corresponding effective indefinite number of invoice text a
According to.
In the present embodiment, invoice field corresponding with data undetermined is determined by minimum spacing, is adapted to difference
Invoice pattern.Meanwhile machine dismiss ticket invoice text may not go together with data undetermined, possibly even wrong row (similar Fig. 3 institute
Show), for example amount issued printed to date a line of making out an invoice；If directly being closed according to the position between invoice data and invoice text
System is to determine field corresponding to the data undetermined, then there may be erroneous judgements.The number of data undetermined is primarily based in the present embodiment
The invoice field that data undetermined may belong to is judged according to format, is corrected again based on invoice text later, it can be more quasi-
Really determine invoice data corresponding with target invoice field.
It should be noted that " the invoice text d " of the multiple data undetermined of correspondence in Fig. 3 is usually " amount of money ", accordingly
Invoice text a and b are article of consumption respectively, for example are " mobile phone " and " computer " respectively, then corresponding data 1 undetermined are exactly mobile phone
Price, data 2 undetermined are the prices of computer.But " amount issued " in invoice field is actually total amount, if invoice
Text c is " total amount ", then and the corresponding data 3 undetermined of invoice text c are only invoice data corresponding with amount issued.At this time
Can be by " invoice text c " as invoice text corresponding with " target invoice field ", namely which data undetermined only considered
It is minimum with the line space or column pitch of invoice text c.
In addition, invoice includes many numbers, i.e., data undetermined, such as invoice codes, invoice number, invoice, check code
Etc. corresponding number；Invoice be directly write exactly number meaning, such as " invoice number: 12345678 ", and some only
There are a number, such as " 12345678 ", not writing this number exactly is " invoice number ".That is, the invoice data in invoice
It is than more complete, and invoice text may be imperfect.Alternatively, the same invoice field may be different in different invoices
The form of expression, i.e., different invoice text, such as " invoice number " this invoice field, the specific manifestation in invoice image
Form (i.e. invoice text) may be " invoice number ", it is also possible to " No. ".Invoice data is first identified in the present embodiment, later
Corresponding invoice field is determined again, even if the invoice field in invoice is imperfect, can also clearly and completely be determined all
Invoice information.
On the basis of the above embodiments, above-mentioned steps 1023 " choose a data undetermined to make from multiple data undetermined
For effective data undetermined " include:
Step C1: it according to having determined that and the data undetermined of invoice field corresponding relationship and corresponding invoice field, determines
Relevant identification information.
Step C2: using the invoice field of the multiple data undetermined of correspondence as target invoice field, in target invoice field pair
When in the invoice data answered including identification information, using the data undetermined to match with identification information as effective data undetermined.
In the embodiment of the present invention, it can identify that other are unidentified according to the invoice data and invoice field that have identified
Invoice data.Specifically, determining relevant identification information according to the invoice data and invoice field that identify, basis should later
Identification information identifies the corresponding data undetermined of target invoice field.Wherein, which is specifically as follows date information, position
Set relationship etc..For example, the format on date of generally making out an invoice is special, it is easier to identify, is identifying date of making out an invoice corresponding invoice
After data, that is, it can determine the time (i.e. identification information) made out an invoice；And in invoice codes the 6th~7 expression of years code (such as
18 indicate 2018), can be chosen at this time according to the time on date of making out an invoice the 6th~7 of data undetermined be the time to
Fixed number is according to as effective data undetermined.Alternatively, the identification information can be positional relationship.For example, general invoice codes and invoice
The neighbouring arrangement of number can be using 8 bit digitals below invoice codes as invoice number after identifying invoice codes.
Optionally, with the prevalence of electronic invoice, invoice, which easily exists, repeats the case where submitting an expense account.To solve this problem, at this
In embodiment, after step 103 " verification result for obtaining invoice validation system feedback ", this method further include: when verifying is tied
Fruit is to submit an expense account flag bit when being verified for invoice information setting, and after the corresponding target invoice of invoice information is submitted an expense account, more
The reimbursement flag bit of new invoice information.
In the embodiment of the present invention, invoice database can establish, can also be deposited according to the invoice information that invoice image recognition goes out
Storage is every invoice information setting reimbursement flag bit in database, for example do not submit an expense account invoice letter in the invoice database
The reimbursement flag bit of breath is 0, and the reimbursement flag bit for having submitted an expense account invoice information is 1.It can determine and be somebody's turn to do according to the reimbursement flag bit
Whether the corresponding invoice of invoice information has been submitted an expense account, so as to avoid repeating submitting an expense account.
A kind of invoice provided in an embodiment of the present invention knows method for distinguishing, can carry out automatic identification to invoice, and identify
Invoice data is filled into invoice validation system true to invoice by invoice field and invoice data in invoice image automatically later
Puppet carries out inquiring and authenticating, and the available verification result to invoice validation system feedback, true so as to automatically determine invoice
It is pseudo-.Which does not need manual verification, can largely save time and the cost of staff, improves the speed of verifying true from false of bills
Degree and efficiency.Meanwhile passing through the effective invoice field of determination, it is possible to reduce the treating capacity of image recognition improves recognition efficiency.Pass through
The mode for identifying invoice data first, further increases the accuracy of identification；And the data format for being primarily based on data undetermined is come
Judge the invoice field that data undetermined may belong to, is corrected, can more accurately be determined based on invoice text again later
Invoice data corresponding with target invoice field.
The method flow of invoice identification is described in detail above, this method can also be realized by corresponding device, below
The structure and function of the device is discussed in detail.
