Description

Apparatus for recognizing hand-written characters
The invention relates to character is written on the tablet pattern tablet with hand, and read character, carry out the dictionary control treatment, the apparatus for recognizing hand-written characters of identification input character.
Apparatus for recognizing hand-written characters of the present invention is to set a plurality of writable character frames of going into 1 above character in the character input field of tablet pattern tablet, when identification writes the character of character input field, utilize and export its identification character sign indicating number and character position coordinate thereof in couples, then can grasp the character frame of charging to character, therefore, character writes personnel can import the character of number arbitrarily in the character frame, thereby can realize easily writing character and improve operating efficiency.
In the past, there is the people to propose in the literal input field of tablet pattern tablet, to set the scheme that a character frame can only be charged in a plurality of each character for this character recognition device.But in the time of in this way, character writes personnel when writing character manipulation, watching attentively always unexpectedly the character frame about, left and right sides Ge Bian, this has just increased the weight of the mental burden that character writes personnel significantly, widely, has reduced work efficiency.
Therefore, the apparatus for recognizing hand-written characters of the present inventor's exploitation can be charged to the mode of a plurality of characters owing to adopted in a character frame, thereby solve existing problem in the such scheme.
Utilize this device, character writes the limit, the left and right sides that personnel needn't expressly remove the attention character frame, then character can be logged in the character frame, and this has not only alleviated the mental burden that character writes personnel widely, and character charges to easily, improved the efficient of character write operation.
Yet, this mode hand-written gone into disposal system etc. that recognition device refers to the dedicated processes numeral when going up, can numeral be charged in the character with spacing freely, and the figure place that will charge in the character frame is defined as fixed value.Root this, when numeral input reaches the regulation figure place, then process object can be moved on on the character late frame.
But character writes personnel on one side needs the interior digit of attention character frame often, Yi Bian hand-writtenly go into numeral.In addition, when the numeral of input when following, needs the key input at interval in the regulation figure place, perhaps hand-writtenly go into " 0 ", to reach the figure place of defined.This has become the increase literal to write personnel's homework burden, hinders the main cause of increasing work efficiency.
The purpose of this invention is to provide a kind of novel hand-written character recognition apparatus.This device is in the character input field of tablet pattern tablet, set a plurality of when can be hand-written going into the character frame of 1 above character, particularly when digital input operation, needn't go the figure place of the numeral in the attention character frame fully, nor must go to proofread some loaded down with trivial details operations such as figure place.
For achieving the above object, the present invention has, and sets the character frame tablet pattern tablet that a plurality of experts write an above character in the character input field; Go into the input pen that character is used with hand-written, make nib can touch the tablet pattern tablet; And from the character input field of tablet pattern tablet, read and write character, carry out character recognition, and the recognition processor of output identification character sign indicating number.Above-mentioned processor controls is by trying to achieve input character location coordinate in the character input field, this coordinate information and above-mentioned identification character sign indicating number are exported in couples being constituted.
Utilize device of the present invention, can grasp the hand-written character frame of going into of this character according to coordinate information, therefore, needn't regulation need charge to number of characters in the character frame etc., like this, character writes personnel can the attention provision figure place etc., can import the character of any number.And, also needn't import interval or " 0 " and come filling figure place etc.Therefore, alleviated character significantly and write personnel's homework burden, and alleviated operating efficiency etc. significantly, reached goal of the invention and significantly imitate and play.
The 2nd figure represents to quote the disposal system complete machine skeleton diagram of numeral etc. of the hand-written character recognition apparatus 7 of this invention.Hand-written character recognition apparatus 1 shown in the figure is made of tablet pattern tablet 2 and recognition processor 3.The each several part of these devices is connected with the device 4 of lead and main frame, and the main frame 7 that the device 4 of main frame is made up of display 5 and keyboard 6, main frame are connected with printing 8 and diskette unit 9 again.
Above-mentioned recognition processor 3 is by CPU (central processing unit) CPu(Central Processing Otit), random memory ram (Randam Access Memory), read-only memory ROM(Read only memory) etc. the computer circuit of storer is formed.Utilize this recognition processor 3 discriminably to hand-written character input reason, comprise that a series of character recognition of dictionary contrast are handled, and the output of recognition result processing is controlled.
Above-mentioned tablet pattern tablet 2 is owing to be provided with character input field 10, contact keypad 11 and fault display lamp 12 on graphic tablet; Each distinguishes 10, the 11 contact situations of nib that can feel special-purpose input pen 13.Contact keypad 11 comes selection operation by the nib of input pen 13, is furnished with to be several function keys such as key input various command.Character input field 10 makes the nib of input pen 13 contact with the graphic tablet face, also move, and it is used for the hand-written character of going into will write.In the inboard of above-mentioned graphic tablet face, corresponding with character input field 10, form coordinate by matrix circuit and detect the loop, utilize this loop to detect Building X mark and Building Y mark with the nib of character input field 10 contact positions.
On above-mentioned character input field 10, the character frame 14 1 of rectangle of growing crosswise connects and forms several sections, any number numeral all hand is written in the frame of these character frames 14, after the account of identical character frame printing is marked on and locatees on the graphic tablet face, with input pen 13 with numeral one by one hand be written in this character frame, like this, each numeral is identified in order, this identification character sign indicating number, output in couples on the device 4 of host computer side with the location coordinate of this character input field 10, at this moment, above-mentioned recognition processor 3 is when having the stroke input, the stroke that hand-written character constitutes is discerned processing, and check the mutual alignment relation of each stroke input, judge that whether its input character is after the numeral that constitutes of Multi strokes, differentiates the result according to stroke recognition result and numeral, access character, deliver on the device 4 of above-mentioned main frame.
The character " 4 " that the 5th figure (a)~(d) expression Multi strokes constitutes access example.In the (a) and (b) of the 5th figure, first stroke and the 2nd stroke has certain position relation, can discern, and accesses character " 4 ".But the 1st stroke and the 2nd stroke when not having certain position relation, during as the 5th figure (c), (d), handle as error originated from input.In (b) of the 5th figure, first stroke at first is identified as " 7 " afterwards, and in the time of the 2nd stroke, identification obtains corrigendum.The result is " 4 ".In the 5th figure (c), first stroke of quilt discerned mistakenly, and the 2nd stroke is identified as that " 1 " handle.
When above-mentioned input pen 13 contacts on the tablet pattern tablet 2 when nib, and when adding certain pressure, for example, on nib, produce the structure of the magnetic line of force, and on tablet pattern tablet 2, utilize to detect the motion track of this magnetic line of force, obtain the data of each stroke of the input character of starting writing from starting to write to.
The 3rd figure represents the memory content of recognition processor 3.There are a series of programs that usefulness is handled in character recognition program area 15 among the figure.There is coordinate counter 17 workspace 16, and pen stroke counter 19 is divided, direction code memory block 20, stroke sign indicating number memory block 21, coordinate counter protected location 22, stroke sign indicating number protected location 23 etc. in coordinate memory block 18.The number that on coordinate counter 17, has input pen 13 coordinate points by on the tablet pattern tablet 2 time; the location coordinate of each that has on the coordinate memory block 18 that input pen 13 moves on tablet pattern tablet 2; the number that has 8 direction codes (shown in the 4th figure) that comprise stroke on the branch pen stroke counter 19; 8 direction codes that have each minute stroke (aftermentioned) that constitutes stroke on the direction code memory block 20; store the code of pressing the species that have the particular stroke input on 21 at the stroke sign indicating number, have the coordinate counter 17 in regulation stage and every content of stroke sign indicating number memory block 21 on coordinate counting protection pressure 22 and the stroke sign indicating number protected location 23.Stroke identification is with having in the dictionary district 24 by relevant normal datas that contrasts usefulness such as 1 stroke of digital " 0 " of forming " 2 " " 3 " " 6 " " 8 " " 9 " in addition.And have numeral " 4 " " 5 " the contrast normal datas such as " 7 " that Multi strokes is formed in the dictionary district 25 that digit recognition is used.
Fig. 1 represents the control action of above-mentioned identification handling part 3.At first, will discern the handling part initialization, remove the content of above-mentioned stoarge workspace 16 in the 31st step.Then, the 32nd step was judged the instruction input that has or not from graphic tablet 2 key zones 11.At this moment, press the key of demand graph tablet input.At this moment, the judgement of " the having or not the instruction input " in the 32nd step and the judgement of " the having or not the input sign on " in the 33rd step are " YES ", enter for the 34th step, remove the content of stoarge workspace 16.If press other instruction enter key, then the 33rd step became " NO ", entered for the 35th step, and this order code flows to main frame.
So, the character input field 10 of input pen 13-contact pattern tablet 2, the pen that adds regulation is pressed, being judged as of " have or not instruction input " in the 36th step " NO " then, being judged as of " whether starting to write " " YES " in the 37th step, then in the 37th step with stroke input processing subroutine shown in Figure 6.
At first, in the 71st step of Fig. 6, judge starting to write a little whether in character frame 14 of above-mentioned 37 steps.Be judged as " YES ", the content of coordinate counter 17 adds 1, and the coordinate in the graphic tablet 2 detects loop detecting pen location coordinate simultaneously, and is stored in (the 72nd, 73 step) in the coordinate memory block 18.If nib moves, stroke draws in same character frame 14, being judged as of " whether starting writing " " NO " in the 74th step then, so returned for the 71st step, being judged as of " whether in the character frame " " YES ", and with above-mentioned the same, the coordinate counter adds 1, and a storage location coordinate (the 72nd, 73 step).
When coordinate points was passed through in the position of nib at every turn, this was handled action and just repeats once.A stroke end of input, when nib left graphic tablet 2, the judgement in the 74th step was " YES " just, and entered for the 75th step.
In the 75th step, the coordinate that above-mentioned stroke is imported point jumpy (point that 90 ° of variations for example occur) occurs as the change point detection, disconnects with the stroke of each change point with this character, is divided into a plurality of minutes strokes.
(1) of Fig. 7, (2) show the branch stroke segmentation example of character " 2 ", " 5 ".Among the figure, stain 26 expressions are started to write a little, and stain 27 expressions are started writing a little, white point 28 expression change points, and straight line 29 expressions divide stroke.
Above-mentioned each minute stroke, become the direction code shown in the numeral 1~8 among Fig. 4 according to its direction transformation.The branch stroke number that constitutes stroke in the 76th step is inserted branch pen stroke counter 19.Then in the 77th step each minute stroke direction code store in the direction code memory block 20.
Fig. 8 illustrates the direction code conversion example of first stroke of character " 5 ".The direction code of 5., 2., 3., 4., 5., 6., 7., 8. representing each minute stroke among the figure.During this code conversion, adjacent direction code links to each other (2.~8. part of illustrated example), then carries out so-called graphics process, promptly 3. 5. 7. represents long stroke with direction code.
Fig. 9 represents the direction code row of the character " 5 " after circular the processing.5. 3. 5. first stroke have 7. all directions sign indicating number, and 3. second stroke have direction code, constitutes this two strokes respectively.
Then, above-mentioned stroke input contrasted with the content of stroke identification with dictionary district 24 in the 78th step, and whether check exists has the normal data that is listed as corresponding to direction code row with stroke input direction sign indicating number.When having consistent data, being judged as of " whether consistent " in the 79th step " YES " inserted stroke sign indicating number memory block 21 in the 80th step with the code (to call the stroke sign indicating number in the following text) of the specific character stroke relevant with this normal data, and returned master routine.On the other hand, when not existing with dictionary district 24 corresponding to normal datas, the 79th step then was " NO ".At this moment as input error, return master routine equally.
In the written character stroke process during nib shiftout character frame 14, being judged as of " whether in the character frame " in above-mentioned the 71st step " NO " sent wrong voice signal in the 81st step, and the wrong pilot lamp 12 on the graphic tablet 2 brightens in the 82nd step simultaneously.At this moment nib is mentioned from graphic tablet 2, so the 83rd step for " YES ", as input error, was returned master routine.
So when returning from above-mentioned the 79th, 83 steps as input error, the 39th step of Fig. 1 is " YES ", produce wrong acoustic signal in the 40th, 41 steps, and wrong pilot lamp 12 brightens.Then insert coordinate counter 17 in the value (at this moment being initial value 0) of the 42nd step coordinate counter protected location 22.
Otherwise, when returning master routine owing to end of input, the 39th step be judged as " NO ", then entered for the 43rd step, check whether the content of stroke sign indicating number protected location 23 is 0.At this moment, because this protected location 23 is an original state, be 0, so the 43rd step was " YES ".The 44th step judged whether the stroke input of above-mentioned contrast unanimity is correct stroke, judged promptly whether this stroke is imported is the stroke of the numeral " 4 " that is made of a plurality of strokes, " 5 ", " 7 ".The 44th the step be judged as " NO " time; promptly conclude when the input of this stroke is the stroke of the digital " 0 " that is made of a stroke, " 2 ", " 3 ", " 6 ", " 8 ", " 9 " (except " 1 "); flow to main frame 4 together at the 45th coordinate (coordinate) and the stroke sign indicating number of this character that goes on foot the character input field 10 of this character position for starting to write a little in this example; remove the content of coordinate counter 17 and two protected locations 22,23 in 46,47 steps then, wait for stroke input next time (the 37th step).
On the other hand, when stroke input was the stroke of the numeral " 4 " that is made of several strokes, " 5 ", " 7 ", being judged as of the 44th step " YES ", and entered for the 48th step checked that this stroke is whether as numeral " 1 " formation character itself.The 48th the step be judged as " YES " time; then flow to main device 4 together with this stroke sign indicating number at the 49th point coordinates of starting to write that goes on foot this stroke; in the 50th step, the value of coordinate counter 17 is inserted protected location 22; to receive into stroke sign indicating number protected location 23 in the stroke sign indicating number memory block 21, wait for stroke input next time (the 37th step) then.
Otherwise; when stroke self did not constitute character, the 48th step was " NO ", in the 51st step the value of coordinate counter 17 was inserted protected location 22; to receive into another protected location 23 in the stroke sign indicating number memory block 21, wait for stroke input next time (the 52nd step) then.If stroke input is next time arranged, then the 52nd step was " YES ", carried out the stroke input in the 38th step and handled.On the other hand, if do not have in the stipulated time stroke input then the 50th step be " NO ", being judged as of " whether the time surpasses " in the 53rd step " YES " changes following fault processing of 40 steps over to.
Now, if handwritten numeral " 4 " import.At this moment, if the end of input time of stipulating first stroke shown in Fig. 5 (a), then this stroke input of first stroke itself can not constitute character.So, above-mentioned the 48th step be judged as " NO ", the content of coordinate counter 17 of relevant this stroke input and the content (the 51st goes on foot) of stroke sign indicating number memory block 21 are inserted in each protected location 22,23.Then, if second stroke stroke of handwriting characters " 4 ", then the 52nd step was " YES ", and is identical with above-mentioned the 38th step, carries out the stroke input of being undertaken by Fig. 6 master routine and handles.At this moment return master routine, the 39th step was " NO ", and the 43rd step was " NO ", entered for the 54th step.The 54th step judged whether the stroke input is paired stroke.At this moment, the 54th step be judged as " YES ", entered for the 55th step.In the 55th step, the combination of two strokes inputs of first stroke and second stroke is contrasted with the content of digit recognition with dictionary district 25, whether inspection exists to have with this direction code is listed as the normal data that corresponding to direction code is listed as.When having consistent data, being judged as of " whether contrast is consistent " in the 56th step " YES " then is used for the relative position of the paired stroke of program (not shown) inspection in the 57th step.
In this master routine, check that whether above-mentioned paired stroke input is which structure stroke of character " 4 ", " 5 ", " 7 ", check the mutual alignment relation condition whether up to specification of each stroke input subsequently.
Figure 10 illustrates start to write an a, c that relevant character " 4 " constitutes stroke start writing a b, d and the coordinate position of change point e.For example, check following condition respectively: the y coordinate values y that 1. puts c cWhether greater than the mean value ((y of e, b point y coordinate values e+ y b))/2; 2. put the y coordinate values y of d dWhether less than y coordinate values the mean value ((y of e, b e+ y c))/2; 3. put the Building X scale value X of e eWhether less than the mean value ((Xc+Xd))/2 of the Building X scale value of a c, d; 4. put the Building X scale value X of b bWhether greater than the mean value ((X of the x coordinate values of a c, d c+ X d))/2.When each condition all satisfies, just conclude that each paired stroke input is the formation stroke of character " 4 ", and return master routine.But when having which condition not satisfy, conclude that then each paired stroke input is not the formation stroke of character " 4 ", and return master routine.
Separately condition is also set in character " 5 ", " 7 ", implement conditional test same as described above.
Therefore, after which is the structure stroke in judging character " 4 ", " 5 ", " 7 ", the 57th step " condition of mutual alignment relation is coincide? " judgement become " YES ".In the 58th step; the coordinate of the character input field 10 at that character place (being a little the coordinate of starting to write of first stroke in this example) and this stroke code send to host apparatus 4 in couples; remove the content (the 46th, 47 step) of coordinate counter 17 and each protected location 22,23 then, wait for the input (37 step) of character late.
In contrast, above-mentioned 56 steps or 57 steps be judged to be " NO " time, entered into for 59 steps, import the stroke of the 2nd stroke, whether check stroke itself has constituted character.When this is judged to be " YES ", turned back to for 45 steps, become the state of the start to write point coordinates and the stroke code transmission main frame thereof of the 1st stroke.If 59 steps be judged to be " NO ", just turned back to for 40 steps, as the stroke fault processing.
And stroke input mutual alignment relation is not limited to the conditional test of above-mentioned example, also can import, check other condition.
The 11st figure represents the memory content of host apparatus 4.The program area is 60 li in the drawings, has stored to receive and has handled from the instruction of hand-written character recognition apparatus 1 and the program of character recognition data, has stored a series of programs relevant with system handles in addition.Distinguish 61 li in the record of account ticket format information, deposited the account ticket form (location coordinate of the number of character frame and character frame etc.) that is arranged on the above-mentioned graphic tablet 2.
Workspace 62 has reception number of characters memory block 63, receives character memory block 64, character frame number storage district 65 and received block scale value protected location 66 etc.Receive the 63 li number of characters that receive a character frame in number of characters memory block; Receive 64 li identification character sign indicating number and the coordinate information thereof that received from hand-written character recognition apparatus 1 in character memory block; Be provided with the character frame number relevant in the character frame number storage district 65 with receiving character; Received block scale value protected location is provided with the coordinate information in the reception character memory block 64 of inserting the defined stage for 66 li.
Host apparatus 4 has the zone by character frame storage reception information.In each zone, be provided with maximum number of digits memory block 67, character counter 68 and character memory block 69.Maximum number of digits memory block 67 is provided with the storage numeral of maximum number of digits.The number of 68 pairs of store characters of character counter is counted.Character memory block 69 is in rapid succession to receiving character with the corresponding address storage of the value of character counter 68.
Figure 12 represents the control action of main frame 4, at first carries out initialization when 91 steps, removes the content of the workspace 62 of above-mentioned storer.Then, read the content of account ticket format information memory block 61, at the picture of display 5 and on show after the form of the ticket of entering an item of expenditure in the accounts, allow to receive the information (92 steps, 93 steps) of self terminal (comprising hand-written character recognition apparatus 1).
In this stage, hand-written character recognition apparatus 1 sends to main frame in couples with identification character sign indicating number and character coordinate information thereof, main frame 4 has received this information, 94 go on foot " having received " then? be judged to be " YES ", 95 the step " received content be the instruction? " judgement become " NO ", leave this reception information in reception character memory block 64 li, and be arranged on 63 li of reception number of characters memory blocks receiving a number of characters " 1 ".Meanwhile, according to next step 96 coordinate information that receives, it is relevant with which character frame to retrieve this information.
When having received instruction under above-mentioned accepting state, 95 steps became " YES ", and 97 steps forbade receiving from after the terminal information, carried out handling with this instruction is corresponding in 98 steps.
In 99 steps, whether the character that check receives is initial character, at this moment because of being judged to be " YES ", so entered for 100 steps.100 steps were that the character frame number with above-mentioned retrieval is arranged in the character frame number storage district 65.Then, in 101 steps, remove the character counter 68 of this character frame and the content of character memory block 69.Meanwhile, 102 steps were also removed the interior character of this character frame that display 5 shows.Then, the coordinate information in the reception information is stored in 66 li of received block scale value protected locations (103 step), again will be in this character frame that display 5 shows foremost the initial character that receives of position show (104 step).In 105 steps, be on the numeral of above-mentioned character counter 68, to add 1.106 steps be the value of this character counter 68 as relative address, leave the code that receives character in character memory block 69 li.Then, turned back to for 94 steps, wait for the next information that receives.
Then, one receives the information of second character that comprises this character frame, 99 the step " being initial character? " be judged to be " NO ", 107 the step " identical characters frame sign indicating number? " judgement become " YES ", just enter into 108 the step.Whether the content that the 108th step was judged above-mentioned character counter 68 is less than the content of maximum number of digits memory block 67.Be judged as " YES " as if 108 steps then checks in the 109th step whether the character coordinate information of existing reception is consistent with the memory contents of received block scale value protected location 66.That is to say the 109th step checked whether the initial character that receives is equivalent to first stroke of first reception character.It is judged as " NO " (two characters are different characters) time, in the 110th step the coordinate information of the character of second reception is inserted protected location 66, the character in the 111st step with this reception is presented on the display 5.Transfer to above-mentioned the 105th step then, on character counter, add 1, then go on foot the storage of carrying out to character memory block 69 the 106th.
On the other hand; the 109th the step be judged as " YES " (two characters are identical) time; the 112nd step will be stored in the protected location 66 on once coordinate information remove; a character (at this moment being initial character) in the 113rd step, showing on the cancellation display 5; the character that will now receive in the 114th step is presented on the display 5 then; transferred to for 106 steps subsequently, change the memory contents of character memory block 69.
Above-mentioned a series of processing angle receives a character and just repeats once, so shows the character that receives successively on the display 5, and character counter 68 adds 1 one by one simultaneously, and the information that 69 storages receive in the character memory block (the 111st, 105,106 step).When the count value of character counter reaches maximum number of digits; the 108th step be judged as " NO "; at this moment; when only the coordinate information of a last character of storage is consistent in the coordinate information of the character of count value at character counter 68 consistent with maximum number of digits (the 115th step was " YES ") and reception and the protected location 66; just returned for the 112nd step, implement to receive the demonstration of character.Otherwise which in the 115th, 116 steps, it was excessive then to become input when being judged as " NO " in step, and entered for the 117th step, showed mistake on the picture of display, and produced wrong acoustic signal.Then character counter adds 1 in the 118th step.
So the reception processing of a character frame finishes,, just retrieve corresponding character frame (the 96th step) according to its coordinate information if receive the character information of character late frame.At this moment, because the numbering of the character frame of retrieval is inconsistent with the character frame numbering of inserting character frame numbering memory block 65, so being judged as of " whether being identical character frame " " NO " in the 107th step inserted new character frame numbering in the 100th step, carries out the following processing of the 101st step then.
