Below, describe embodiments of the invention in detail.
The address of being put down in writing on the paper spare, for example in Japan, by represent what number etc. was formed corresponding to postcode, counties and cities district, Dou Dao mansion street name and the address of city's realm name, usually district street, counties and cities, Dou Dao mansion name roughly is a Chinese character, and the address represents that number then is expressed as numeral and label symbol.Among Shuo Ming the embodiment, be the beginning that a coding (calling street name sign indicating number in the following text) of the compositions such as numeral corresponding with the street name is attached to the address below.Below, the address that calls of containing this street name sign indicating number, counties and cities district, Dou Dao mansion street name and the residence number of expression.
In addition, one of the address be illustrated among Fig. 2.Among the figure, 1A is a street name sign indicating number, and 1B is city's realm name/street name, and 1C is that number is represented in the residence.At this point in the example of location, preceding 3 figure places of street name sign indicating number 1A i.e. " 183 " are equivalent to given postcode now, are expression " Fu Zhong city " in the case, and street name sign indicating number 1A back 3 promptly " 123 " be the street name, corresponding to " Ri Xinding ".
Below, with reference to accompanying drawing the 1st embodiment of the present invention is described.
In this embodiment, the input characters row that are equivalent to the address are word-for-word carried out literal identification, and judge word kind (Chinese character, numeral, symbol etc.) according to the result of identification.From the beginning of input characters row detected words kind in turn, at first the continuous part of numeral or symbol is regarded as street name sign indicating number then, detect the word kind again and be converted to the position of numeral or symbol, its later part is regarded as the residence number of expression from Chinese character.Discern the address in conjunction with this street name sign indicating number and the residence number of expression.
Fig. 1 is the block diagram of embodiment 1, and visual extraction unit 101 becomes the electric diagram picture signals to literal on the paper spare or symbol etc.
Address location detecting element 102 detects the information such as number of length, direction and row of the text line of the picture intelligence that becomes in visual extraction unit 101, detect the text line that conforms to contained address on the paper spare according to the information that is detected.Detect technology as position, this address, can consider to adopt disclosed technology in the applicant's for example the special public clear 59-39065 communique.
In the public clear 59-39065 communique of spy, at the uniform velocity carry the note of mail that one side of addressee's name address is arranged with certain width range scanning, therefrom text line carry out compressing during certain and detect therefrom warp certain during the initial and final position of text line of compression, again the addressee's name group of addresses on the mail of the compression text line combination that obtains therefrom and the gradient of its row, position, literal size and row etc. are differentiated.
Literal is selected portion 103 text line that detects as the address is selected processing seriatim.Select technology as this literal and can consider to adopt disclosed technology in the applicant's for example the special public clear 63-57831 communique.
In the special public clear 63-57831 communique, when input operation signal is compressed and upgrades along the direction vertical with scan-line direction, the suppressed range that stores each literal module in the sweep signal of compressing successively, and with the compression sweep signal and input scan signal compare, do not represent in the pairing input scan signal of continuous literal module for compression that literal that the part occasion of literal is done selects action and detect, and read the suppressed range that the synchronous regime selected with literal is stored.
Open in the flat 1-94490 communique the spy, the test pattern modularization of identification with same classification in the character library, at this classification Inner the setting value of Halfway Stopping contrast is upgraded with diminishing one by one, and inconsistent at it be to end such purpose contrast at 0 o'clock, then 1 inconsistent number of minimum for 1 classification is as a result of exported.
Open in the flat 2-137080 communique the spy, from feature pattern storage portion, read the feature pattern signal, from reference pattern storage portion, read each reference pattern of respectively reading object word kind, during not unison on asking feature pattern each several part field and reference pattern between the counterpart field, feature series of having added all directions of recording and narrating feature pattern each several part domain features and the series that obtains for one one of the feature series of the adjacency on each feature series adjacent part field are formed the feature series of multiple class in additional a plurality of modes, on all directions, former feature series and formed multiple category feature series each and and the feature series of the serial corresponding reference figure of former feature between carry out non-linear coupling, because the evaluation value of the non-linear coupling of all directions is that the sum total of its minimum value is decided to be not unison between the certain fields, just determine not unison with reference between the figure of character and graphic and each word kind thus, according to this not unison classification, and the result who is told is exported.
Word kind detection unit 106 is according to judging word kind (Chinese character, numeral, symbol etc.) from the recognition results of the used literal in the address of character recognition portion 104 outputs, promptly, when the literal recognition result in the character recognition portion 104 is exported with JIS flip-flop, if No. 2300 positions of its JIS flip-flop (preceding 3 of coding is 233) judges that then this literal is the arabic numeral of " 0 "～" 9 ", if JIS flip-flop No. 3000 more than the position (the 1st of coding more than 3) judge that then this literal is a Chinese character.Judge similarly that for symbols such as marker characters Fig. 3 represents that the word kind declares word result's a example.
107 in Address Recognition portion at first is listed as from its beginning part according to pair input characters corresponding with the address of the result of determination in the word kind detection unit 106 in turn detects its word kind, and the continuous part of numeral or symbol is looked do street name sign indicating number and temporarily store.Detect the transfer point of word kind from the Chinese character to the numeral of input characters row again, promptly detect the starting position of the residence number of expression, and this starting position later numeral and symbol be considered as the residence number of expression, then, discern the residence in conjunction with the street name sign indicating number and the residence number of expression of temporary transient storage.
Below, more this address recognition device is made specific description.
On paper spare, for example, the text line that is equivalent to the address shown in the image pattern 2 is recited as " new raised path between farm fields 1-10 of market day in the 183-123 mansion ", and this text line is the street name sign indicating number 1A that is put down in writing by the address beginning, and counties and cities district, Dou Dao mansion street name 1B and the residence number of expression 1C form.
At first, visual extraction unit 101 is converted to visual electric signal (step 401 shown in Figure 4) to literal on this paper spare and symbol etc.This picture intelligence that extracts is defeated by address position testeding outleting part 102, and address position testeding outleting part 102 detects position, address (step 402), and the extraction text line suitable with the address, i.e. the picture intelligence of " new raised path between farm fields 1-10 of market day in the 183-123 mansion ".
Then, the input characters that is extracted in the address position testeding outleting part 102 is listed in literal to be selected and one by one carries out literal in the portion 103 and select (step 403), again literal that character recognition portion 104 is selected this respectively with literal pool 105 in Inner hold and contrasted, promptly, character recognition portion 104 is when making text point return initial value (i=1: step 404), character library number is returned initial value (j=1: step 405), and the literal of text point P (i) and the literal of character library No.D (j) are compared (step 406).Fig. 5 (a) shows the relation of input characters row and text point P (i), the relation among Fig. 5 (b) between expression character library No.D (j) and character library, classification (JIS flip-flop), the word kind.
In the word kind detection unit 106, acceptance is from results of comparison r (the 1)～r (n) of identification part 104, and the stored position of results of comparison returned initial value (i=1: step 412), according to the classification of results of comparison r (i) the word kind is judged (step 413) then, and it is judged that the word kind deposits among the k (i) (step 414).Relation between word kind and the classification (JIS flip-flop) has been shown among Fig. 6 (a), that is, and during as if " 2330 "≤r (i)≤" 2339 ", be judged to be numeral, if r (i)=" 213D " is judged to be symbol, it is Chinese character that r (i) 〉=3000 declares word, and result of determination is deposited among the k (i).Do you then, whether check i=n? (step 415), if i ≠ n, make i=i+1 (step 416) after, return step 413.In step 415, if i=n, then result of determination k (1)～k (n) is passed to Address Recognition portion 107 from word kind detection unit 106, promptly result of determination k (1)～k (n) as word kind result of determination, being exported shown in Fig. 6 (c).
That is, identification part, address 107 is that from the beginning the input characters row corresponding to the address are in turn detected the word kind, and at first, " 183-123 " regards the street name as the continuous part of numeral or symbol, and gives temporary transient storage.The word kind that detects again in the input characters row becomes digital change point from Chinese character, promptly detects the starting position of the residence number of expression, and starting position later numeral and symbol " 1-10 " are regarded as the residence number of expression.Then, temporary street name sign indicating number " 183-123 " and the residence number of expression " 1-10 " are combined the identification address.
Below, with reference to accompanying drawing the 2nd embodiment of the present invention is described.
In this embodiment, the input characters row that are equivalent to the address are word-for-word carried out literal identification, at first detect the border of city's realm name and street name by the city's realm name in the identification input characters row, detect street name sign indicating number from the literal recognition result again, and detect street name sign indicating number corresponding character number therewith, then, begin to put down in writing the position, and the later input characters in this starting position is listed as the residence number of expression detects according to what the literal number of the boundary position of city's realm name and street name and street name detected the residence number of expression.It is exactly the address recognition result that this residence number of expression is combined with street name sign indicating number.
Fig. 7 is the block scheme of expression embodiment 2 structures, and the structure that portion 103, character recognition portion 104 and character library 105 selected in visual extraction unit 101, address location detecting element 102, literal is all identical with the foregoing description 1, so the explanation of repeating part has been omitted.In the present embodiment, be the literal recognition result in the character recognition portion 104 to be defeated by street name literal count search part 201, city's realm name search part 203 and Address Recognition portion 205.
City's realm name search part 203 is literal recognition result in the character recognition portion 104 and pre-registration are had the Inner of the urban district famous-brand clock 204 of city's realm name to hold to compare and to carry out city's realm name retrieval, retrieve city's realm name like this, and detect the city's realm name in the input characters row and the street name put down in writing thereafter between boundary position.At this, urban district famous-brand clock 204, as shown in Figure 9, registration be the Japan whole nation city's realm name and with the JIS flip-flop of its corresponding character.And the capacity of this urban district famous-brand clock 204 is limited to the degree of about 3000 city's realm names from present situation, and it is very little having the table capacity of street name to compare with registration.
Below, specifically describe this address recognition unit.
In this embodiment, putting down in writing as shown in Figure 2 the text line that is equivalent to the address " new raised path between farm fields 1-10 of market day in the 183-123 mansion " on the paper spare.
At first, visual extraction unit 101 becomes electric diagram picture signals (step 401 shown in Figure 4) to literal on the paper spare and symbol etc.The picture intelligence that is extracted is flowed to address position testeding outleting part 102.Address position testeding outleting part 102 detects text line that position, address (step 402), extraction conform to the address, promptly, the picture intelligence of " new raised path between farm fields 1-10 of market day in the 183-123 mansion ".
Then, the input characters that will be extracted in address position testeding outleting part 102 is listed in literal and selects and word for word select (step 403) in the portion 103.Each all holds with the Inner of character library 105 and contrasts in character recognition portion 104 the literal of selecting again.Processing again identical with the explanation among the embodiment 1 (step 404～411), character recognition portion 104 are exported as the literal recognition result results of comparison r (1)～r (n) with the JIS flip-flop shown in Fig. 5 (d).
Street name literal is counted search part 201 and is obtained results of comparison r (1)～r (n), partly in turn this results of comparison r (1)～r (n) is checked from the outset from character recognition portion 104, extract the classification (step 501 among Figure 10) that conforms to street name sign indicating number, promptly, to as the corresponding input characters in the address of the literal recognition result in the character recognition portion 104 row from the outset part rise and check, detect street name sign indicating number " 183-123 " and kept in.Then, in street name literal numerical table 202 shown in Figure 8, retrieve the literal number " 3 " of the street name " Ri Xinding " that street name sign indicating number " 183-123 " is corresponding therewith, and deposit it among the CNO (CNO=" 3 ", step 502).
With street name literal count in the search part 201 processing simultaneously, city's realm name search part 203 has literal recognition result in the character recognition portion 104 and pre-registration the Inner of the urban district famous-brand clock 204 of city's realm name to hold to compare, and retrieval city's realm name " Fu Zhong city ".Like this, when retrieving its city's realm name " Fu Zhong city ", detecting note has the middle city's realm name " Fu Zhong city " of input characters row " new raised path between farm fields of market day in the mansion " of counties and cities district, Dou Dao mansion street name part and the boundary position of street name " Ri Xinding ".
That is, city's realm name search part 203 is the beginning set positions of city's realm name i=8 (step 503).Make the return initial value of urban district name table position (j=1, step 504) then, and the later result of the literal code of the C of urban district famous-brand clock 204 (j) and r (8) is compared (step 505).If the later result of the literal code of the C of urban district famous-brand clock 204 (j) and r (8) is inconsistent, in step 506, then enter step 507, and make j=j+1 for NO, return step 505.If the later result of the literal code of the C (j) of urban district famous-brand clock 204 and r (8) is consistent, then corresponding with YES in the step 506, enter step 508.In step 508, the border of city's realm name and street name, promptly the beginning position of street name deposits among the CST.Under this occasion, because resulting city realm name is " Fu Zhong city ", so CST=" 11 ".
Identification part, address 205 is the starting position JST (JST=CNO+CST that calculate the residence number of expression in city's realm name search part 203 according to the boundary position (CST=" 11 ") of the street name literal number " 3 " (CNO=" 3 ") corresponding with the street name sign indicating number that detects in the street name search part 201 and city's realm name " Fu Zhong city " that detects and street name " Ri Xinding ", step 509), and regarding the residence number of expression as at this number of expression starting position, residence later record literal " 1-10 " of JST.Then, with this residence number of expression " 1-10 " be temporarily stored in street name literal and count street name sign indicating number " 183-123 " of search part 201 and combine as address recognition result " 183-123 1-10 ".
Promptly, 205 the results of comparison r (1) that conforms to the street name sign indicating number～r (7) in identification part, address deposit among end product f (1)～f (7) (step 510), and in depositing in the later information of results of comparison r (JST) that is equivalent to the residence number of expression after the end product f (8) (step 511), obtain therefrom and identical end product f (the 1)～f (m) shown in Fig. 6 (b).
Below, with reference to description of drawings the 3rd embodiment of the present invention.
Present embodiment is that a lot of preassigned specific regions are being arranged in handled a large amount of paper spare for example, even when the street name sign indicating number in the specific region of this appointment is not documented in the input characters row that are equivalent to the address, also can discern the device in address.That is, being ready to has the street name to reach the character library of the street name sign indicating number corresponding with its street name about the registration of this specific region, infers street name sign indicating number by the street name of being put down in writing in the input characters row.
Figure 11 is the block scheme of expression embodiment 3 structures, visual extraction unit 101, address location detecting element 102, literal select portion 103, character recognition portion 104 and character library 105 all with the foregoing description 1 in identical, the explanation of Therefore, omited repeating part.In this embodiment, the literal recognition result in the character recognition portion 104 being transferred to city's realm name search part 301, street name search part 303, street name literal counts in search part 305 and the identification part, address 306.
City's realm name search part 301 has the Inner appearance of the urban district famous-brand clock 302 of city's realm name to compare and city's realm name is retrieved literal recognition result in the character recognition portion 104 and pre-registration.And when retrieval city realm name, detect city's realm name and the border between the name of street in the input characters row that record counties and cities district, Dou Dao mansion street name part, its result who detects is outputed in street name search part 303 and the identification part, address 306.
In urban district famous-brand clock 302, as shown in figure 12, the record street name sign is " having " on the city's realm name that conforms to preassigned specific region in city's realm name of being registered, and then puts down in writing street name sign " nothing " on the city's realm name that does not conform to.At the street name sign corresponding with the urban district name of being retrieved by city's realm name search part 301 is the occasion of " having ", street name sign " is had " be defeated by street name search part 303.And when the street name sign of the city's realm name that retrieves is " nothing ", street name sign " nothing " is passed to street name literal count search part 305.At this, as far as possible street name sign is appointed as for example processed paper spare for city's realm name of " having " and compares many a lot of regions with other region.
Street name search part 303 is when the output that the street name sign that receives from city's realm name search part 301 " has ", reach from the literal recognition result of character recognition portion 104 outputs according to city's realm name and the boundary position between the name of street from 301 outputs of city's realm name search part, the literal recognition result of the text line that city's realm name is later has the street famous-brand clock of predetermined specific region street name to compare contrast with registration, retrieval street name.On this street famous-brand clock, as shown in figure 13, registration has street name and the street name sign indicating number corresponding with this street name.The street name sign indicating number of street name search part 303 its street names examined of output and street name correspondence.And then the street name of being registered on this street famous-brand clock is only limited to the street name of preassigned specific region Inner, so have the situation of Japanese national street name to compare with registration, its employed capacity is very little.
During street name sign " nothing " in retrieving city's realm name search part 301, literal recognition result according to the input characters row of exporting from character recognition portion 104, from city's realm name of city's realm name search part 301 output and the boundary position between the name of street and count the street name literal number that search part 305 exports from street name literal and detect the reference position of the residence number of expression, and detect the later literal of this reference position and be used as the residence number of expression.Then, this residence number of expression and street name literal are counted in the search part 305 address of discerning that temporary street name sign indicating number combines.
Below, more this address recognition device is specifically described.
In this embodiment, putting down in writing as shown in Figure 2 the text line that is equivalent to the address " new raised path between farm fields 1-10 of market day in the 183-123 mansion " on the paper spare.
At first, visual extraction unit 101 becomes electric diagram picture signals (step 401 among Fig. 4) to literal on this paper spare and symbol etc.The picture intelligence that is extracted is passed to address position testeding outleting part 102.Address position testeding outleting part 102 detects position, address (step 402), extracts the input characters row that are equivalent to the address, that is, and and the picture intelligence of " new raised path between farm fields 1-10 of market day in the 183-123 mansion ".
Then, the input characters that extracts in the address position testeding outleting part 102 being listed in literal selects and word for word selects (step 403) in the portion 103.Respectively selected literal is held with the Inner of character library 105 in character recognition portion 104 again and contrast, afterwards, carry out and same processing (step 404～411) illustrated in embodiment 1, character recognition portion 104 as the literal recognition result, is exported results of comparison r (1)～r (n) with the JIS flip-flop as shown in Fig. 5 (d).
City's realm name search part 301 is to have the Inner of the urban district famous-brand clock 302 of city's realm name to hold literal recognition result in the character recognition portion 104 and pre-registration to compare, retrieve city's realm name " Fu Zhong city ", then, under the condition that retrieves city's realm name, detect the boundary position of city's realm name " Fu Zhong city " and street name " Ri Xinding " in the input characters row of record Dou Dao mansion counties and districts street name part, and this output result is defeated by street name search part 303 and identification part, address 306.In addition because city's realm name " Fu Zhong city " of detecting, be to conform to as shown in Figure 12 preassigned specific region, be " having " so detect street name sign, street name sign " is had " export to street name search part 303 thus.At this moment, because city's realm name search part 301 do not pass to street name literal to street name sign " nothing " and counts search part 305, so it is failure to actuate.
Street name search part 303 is accepted the output that the street name sign from city's realm name search part 301 " has ", reach from the literal recognition result of character recognition portion 104 outputs according to the boundary position between the city's realm name " Fu Zhong city " exported from city's realm name search part 301 and street name " Ri Xinding ", retrieve street name " Ri Xinding " with street famous-brand clock 304, be defeated by identification part, address 306 the street name that detects and with the pairing street of street name name sign indicating number.
