Background technology

Word is the great achievement of human civilization, is record, succession, development civilization and cultural important carrier, is people The important channel of thinking, expression, exchange is social life, study, work indispensable powerful.Specification, clear, height The writing imitate, created an aesthetic feeling is all intension, attainment, ability or even the levels of culture of people and the mark of sentiment and again since ancient times Want component part.With the development of computer technology, the mankind have enter into the information age, and storage, transmission, the processing of word are more Ground electronization, digitlization, networking, need the occasion of Hand writing word fewer and fewer, and people more use keyboard, screen Selection, even voice input word to electronic equipment or computer, and the necessity of personal letter word and importance is made to have reduction trend. Groups of people may think that a to master simultaneously can skillfully use electronics or computer input method, it might even be possible to need not great Fei Word is write in one's own hand in ground practice of being scared.This is the overall background that word is write and the circumstances faced.

But the mode for the acquisition word for being still most natural, most convenient, additional conditions and Least-cost of starting to write, Be also understanding, understand, study, using word basis and must the roads You Zhi, even more people forge thinking, express thoughts, and culture is resistance to The important channel that the heart, logic and creativity, even people are touched one's very soul with heart.The biology bred such as exquisite the Nature It is difficult to identically be copied the same, contact this work of word, lived, with people instinct and person's character by the mankind of crude The work of directly related great creation, it is also not possible to be done completely by machine.In general, if the mankind also want log history, Probe into future, also to learn at all times, thinking advance and retreat, Written Communications, developing creation, then, writing words just will be essential, nothing How rare have by the occasion and quantity of writing！

At all times, people study write, always undergo one from the superficial to the deep, by letter enter it is numerous, from the easier to the more advanced, by not familiar to ripe Practice, from restraining to free training or practice process, finally reaches the unification of heart hand, hand by aroused in interest.Chinese's writing of Chinese characters, the foreigner The foreign languages such as English, French, German are write, there can be no exception whatever for the process of this training.Method correctly and under the time arrives, and can train one Good word oneself writes efficient and handy, and it is errorless and pleasing that others sees that word understands.Write, it is primary certainly just Really, write position, meanwhile, also to write out font, structure and the aesthetic feeling for having quality of specification, in general, the two be it is disposable simultaneously It is formed.Start to learn to write, it is lifelong to be benefited if perfected；If white silk is bad, the later stage is difficult torsion and takes on a new look.So-called " word Product such as moral standing ", " see word as meet ", good word on the other hand is inside and outside minor as a result, be the extraordinary business card of a people and image, It is believed that majority have an intimate knowledge to this, have no objection.Writing style and attainment once being formed, will as temper nature Go deep into marrow, " length " into body, become the characteristic of a people, not malleable, this is the important rule that practice is write.Cause This, writing training requires correct method and perseveres from the beginning, this is extremely important to practising handwriting.

There are five the fundamentals of aspect for writing exercise：The direction of word, font, writing position, the size of word, word.With book Pen is write to discuss, there is hard-tipped pen and soft pen：Pencil, chalk, ball pen, pen etc. are common hard-tipped pen, for expansion it, finger, The characteristics of icking tool, club should also can be regarded as hard-tipped pen, hard brush character be stroke and lines more uniformly, thickness variation it is smaller, write and manipulate letter It is single, it is main to practice font and structure.And soft pen is then the pen with hairbrush or hairbrush pleading writing head, is commonly called as " writing brush ", stroke Line weight variation is apparent, and expressive force is abundant, can realize numerous fonts, but the manipulation of soft pen, operation difficulty are higher, need Be precisely controlled, show font, structure and stroke comprehensively, to the basic training of writer and write skill and technique, ability, attainment require compared with It is high.Soft pen is chiefly used in writing Chinese characters.In general, can finish writing soft word, hard-tipped writing instrument will be easy.Practice with regard to writing For the process and mode of habit, general beginner usually first depicts, including learns to write by tracing over characters printed in red, open up patch, imitate patch, in the book with stroke groove It writes and practises handwriting on plate etc., pursue " likeness in form "；After having certain basis, you can start " facing note ", i.e. reference or comparison copybook or model word, It based on observing, remember, is write in adjacent position, the size of word can change, and focus on " alike in spirit "；It is repeated multiple times undergoing Observation, memory, practice, after forming muscle memory, you can start automation writing, the automation writing at initial stage usually requires to be aided with the Chinese The sphere of movements for the elephants lattice of word or the format line of foreign letter, wait write it is skilled, controlled, can accomplish balmy and bracing after, you can break away from auxiliary Format line is helped, Free Writing is done on plain pape or other media；When reach act freely, write random degree freely and easily after, you can Calligraphy creation is carried out, or even establishes personal writing style, font and school.In short, writing practising be from it is restrained, carried The lower stage shown, which is gradually transitioned into, frees one's minds, exempts prompt, advanced stage for arriving Free Writing or even calligraphy creation again One process assists any method of writing training and scheme all to must comply with this objective law.

It is the body and mind developmental process of people in writing training essence, is the grasp process of an important skill, is one It needs the constraint surmounted all obstacles with bottleneck and obtains free process of writing, thus arduous task, difficulty be not small, needs to pay Go out the cost of the forms such as high time, experience and expense, but because its achievement can benefit from throughout one's life, no matter how high cost is, All highly.Traditional auxiliary writing training articles for use or device are mostly mechanical, such as：Calligraphy exercise-book or copy book, carry The board of groove, " copybook " add " large-character edition ", face note formula copybook, and repeatable " water writing cloth " write or sand table, etc.. Writing training scheme is broadly divided into unidirectional implantation formula and interactive improvement type two major classes：Unidirectional implantation formula training is more likely to learn by oneself Or self training, such as：Calligraphy study course, calligraphy video frequency, calligraphy demonstration etc., only inform what how the person of practising handwriting should write and need to pay attention to Problem, training effect rely primarily on the comprehensibility of practitioner, understandability and feel, and interactive improvement type be mostly " teach-by-doing " or " face-to-face " formula being taught or teaching, such as：Calligraphy gives lessons, calligraphy training class, writes comment etc., not only illustrate the method write, Main points also comment on quality, the gain and loss of writing, it is indicated that deficiency, the gap of practitioner helps to improve, although final effect is still main It depends on practitioner itself, but is trained relative to one-way fashion, interactive still to have a clear superiority, the time limit is short, process is fast, efficiency Height, effect are good, and advantage is derived mainly from comment, points out the abundant and abundant of the feedback informations such as deficiency, thus directiveness, enlightening by education property It is stronger, meanwhile, because the resource that it is used is more, in particular for the auxiliary of the people as teacher so that its costly, cost It is bigger than normal.

Remember as a child to learn white silk to be write big character with writing brush, from learning to write by tracing over characters printed in red, to facing note, then arrives automation writing, a piece of paper has 20 on face The grid or blank boxes of a matts or band " rice " font auxiliary line, write 20 words, can write preferably when teacher reads and makes comments With the circle of red stroke one on word, then to whole word give first, second, third, the total quality of fourth evaluate, can also feel in retrospect now All kindness is obtained, feels that the judge of teacher is very careful, rigorous, highly significant is played to the culture and promotion of basic training of writing Effect.Primary school 6 years has practiced 6 years like this, few daily then to write one page, at most several pages, always unremittingly, just there is it The One-stroke charater of eye is slightly seen afterwards.Present follow-on child is reviewed, as with regard to lucky without.School is not as Pay attention to practicing big word, few will practise handwriting of student adheres into custom, teachers will not it is conscientious like that, patient, for many years such as one Adhere to correcting Brush calligraphy operation to day, or even more used the courseware of the electronic forms such as projection, display screen on classroom, is connected in Write that all seldom or even some are as teacher on blackboard, the writing mastery of itself or the word write all be difficult to flatter.Once geometry When, the writing on the blackboard of teacher is exactly that student learns the important demonstration practiced and write, and is another speechless exchange between teachers and students, is " to explain in words body The important component of religion ", but almost soon disappear now.Students a little learn to write for slightly system, deeply, practice Calligraphy, have to be by parent with going to rush towards training or tutorial class, and ancillary cost pile is not said, just the road of round-trip training class The spent time has been no small cost on way, this is also not counting parent picks the waiting time of child.

The copybook at that time practised handwriting, is mostly that stone inscriptions opens up patch, or the great master of calligraphy that prints authentic work, The Liu style is the Liu style, and the Yan style is the Yan style.The type and style of copybook product on the market are more complicated great miscellaneous now, but do not know be For the reason of the copyright, or in order to pursue the individual character and characteristic of product, a big chunk copybook all alienation, deform, lose mark Accurate and specification taste, exquisite binding and layout and creative layout are difficult to conceal the vague and general of its substantive content and distortion, this is " real Matter content " is exactly word, seem come from some write can be said to be delicate and pretty and have grounding in basic skills people hand, nominal " Liu style ", " Yan style ", but Its font has been apparently not the charm of the authentic Liu style or Yan style word, and only a kind of nameless " body " of someone or Imitative body word, also hardly possible is mentioned in the same breath with everybody real handwriting by the essence of word, gas, god.It is practised handwriting with such copybook, is really " to make a gift of Evil is infinite ", student perhaps can only be allowed to acquire " write good ", practiced to slightly logical fur, and it is difficult to really to train the iron-cloth bottom of writing simultaneously It is drawn into the marrow of calligraphy, the long word that can allow practitioner is without body without god.This just can't help that people is allowed to associate, not as good as from computer Or some standard letters or specification hand-written script are searched, download or transferred and print on internet, it goes as copybook to white silk Word.

With the development of electronic computer and its word processing technology, hand-written inputting method is developed, various hand-written Computer and hand-written electric equipment, product category are various, emerge one after another, and constitute the new way and one of electron assistant writing training greatly Class.

The orderly track of hand-written formation or position sequence are converted to word Internal Code by handwriting input or handwriting recognition technology, after And the word for determining personal letter is screened, and realize the input to computer or electronic equipment, i.e., it is so-called " on-line handwritten recognition ".This skill The further developing stage of art is that existing word, including handwritten word and printed words are identified and inputted, i.e., so-called " off line Identification ".Currently, off-line identification is mainly used in because it is higher to the misclassification rate of handwritten word also remote immature to block letter word In terms of identification.

The core of handwriting input or handwriting recognition technology scheme is to identify and input, and emphasizes the reliability of identification and accurate Property, ignore stroke details, do not recognize font, thus and be not concerned with writing quality or level, also do not solve writing training and closed The font of the heart, stroke details and the problem of write in place, it is seen then that handwriting recognition or writing technology itself are not particularly suited for book Write training.But wherein include to write, thus can derive some auxiliary in its thought and technical foundation and write after all Training program, basic principle are：Under the premise of the word to be write is known in advance, handwriting recognition is by distinguishing write knowledge Whether other result word and precognition word are consistent, to judge whether the word write is correct, and the result word of handwriting recognition often has It is multiple, according to the identifying schemes or foundation taken, best suits, is closest, most possible result word often comes first It is a, become preferred recognition result word, while can also provide other alternative words, is arranged in order from high to low by matching degree, It distinguishes and selects for writer.This " judgement " result is influenced by identification accuracy, so being typically only used for recognition accuracy With the higher regular script word of reliability, and for as running hand and the higher font of these misclassification rates of rapid style of writing, then not using generally, or Person, even with also having little significance.

There are some to operate in the program software on smart mobile phone or computer, by the hand-written key of hand-written screen or computer of mobile phone Disk or other handwriting devices provide writing training, are namely based on the technology or similar with its of aforementioned handwriting recognition.Scheme is：In hand The model word of " learning to write by tracing over characters printed in red " formula is provided on the hand-written screen of machine or computer, as long as the stroke that practitioner's finger or induction pen are write is fallen into It learns to write by tracing over characters printed in red in region, the stroke of screen display can fill up corresponding stroke area of learning to write by tracing over characters printed in red, as long as so completing each stroke of full word Input, system can judge to write correctly, otherwise, can prompt mistake；Some such systems also do the sequence of stroke input It limits, only the order of strokes observed in calligraphy is correct simultaneously, can just judge to write correctly, otherwise, can still be judged to mistake；For those display screens and hand Write the separated computer of input unit, then present on the screen for facing the model word of note, then to writer touch keypad or other The word write on the handwriting device of form compares together together with stroke order, to judge that writes corrects errors.

This kind of auxiliary writing training scheme substantially only training writer correctly write or " word write to " ability, and Not to the writing skill and technique and level of the person of practising handwriting do it is any judge, close examination and intervene, raising or training to writing level " Word is finished writing " energy force effect it is little, or even almost in nothing." word write to " and " word is finished writing " though upper have certain pass writing Connection, but emphasis fundamental difference, in terms of practising handwriting or practicing calligraphy, what people usually more valued, it is also the fact that or objective It is upper prior, exactly " word is finished writing ", writes out quality, high level and aesthetic feeling.This is higher just as some person writing's levels, Although word not being write complete or not writing pair, the writing effect for not revealing out and literal " good ", this " good " are not interfered It is exactly good-looking, have aesthetic feeling, have that power, font be regular, structural coordination.

Due to the limitation of technical solution, it can only be entry level that aforementioned electronic, which assists writing training method and device, it There are two important features：When only it is trained finger is calculated including hard-tipped pen calligraphical works, second is that be only capable of differentiate word write to obtain correctness, wrap The stroke order for including word is write fine or not, the processing of word details, is write for soft pen this higher level writing and word The factor more close with level relationship is write such as font, then be difficult to be related to.

In terms of electron assistant writing training, there is a novel technology to merit attention：2015, Sharp（SHARP）It pushes away A highly sensitive electronic curtain for perceiving brush writing trace is gone out, this technological break-through is that the soft pen of electron assistant writes instruction White silk opens new possibility.But up to now, this screen is highlighted focus of attention and is only limitted to its " high sensitivity ", mainly answers It is used compared with muting sensitivity screen side it to be focusing more on the touch screens manipulation electronic product such as replacement smart mobile phone, tablet computer with direction Face, and in terms of assisting writing training, not yet occur surmounting new departure of aforementioned " entry level " horizontal level, only make existing Screen writing in scheme expands to usable writing brush, is no longer limited to hard-tipped pen, does not occur giving full play to and utilizes this Novel screen " can perceive brush writing " this important feature and being specifically applied to solves the problems, such as " soft writing training of auxiliary ", very It is thoroughly solved the problems, such as " electron assistant writing training " in higher degree of intelligence and deeper, thinner, more fully horizontal level Brand-new scheme, in other words, this new screen not yet " is made the best use of everything ", this can't but be a great shortcoming.

Talk about this, the problem of just there are one seem subtle but must examine, it is necessary to one to carry, here it is write impression and Writing experience.Common writing is started to write on paper.Paper is as writing medium, there are two key property, be exactly flexibility and Absorbency.Hard-tipped writing instrument can be more apparent to flexible impression, and the weight of power is pushed with pen tip, can form the depth in paper Not equal impression, and soft pen writes, and very thoughts are attached on paper to prepared Chinese ink, writing brush head dips the ink of concentration and adhesiveness Paper movement is contacted after juice, writer can experience one deeply attached to each other, continuous resistance without cease.No matter hard-tipped pen or soft pen, paper All there is feedback in face of people, this just sets up a kind of intercommunication sense and a body-sensing between people, pen, paper, ink.In very hard, light That slips is main using glass on the electronic curtain of material, either still to use brush writing with finger, is all not use prepared Chinese ink , it is very big also all to experience gap with writing on paper.The hand-written electricity that screen is detached with touch keypad or other handwriting devices Brain, there is also similar problems.These fine distinctions can all have notable and great influence to writer, as some people, change Fall the pen being accustomed to the use of, or even can feel a little will not write or write bad word.Objectively, lettering pen, writing ink, writing are situated between The height and angle of matter or even writing counter etc. it is any with write related factor, may all influence writing level performance and The exact level of the height of writing quality, influence may vary with each individual, but this influence is objective reality.Therefore, even if the summer It is general to have developed brush writing screen, even if can be based on this screen carries out writing training, but " genuineness " is not achieved Writing impression, be not still ideal writing training scheme.Can not negate hand-written completely and brush writing screen though saying so Curtain and other types hand input device for transitional writing training meaning and value, on condition that the design of scheme will meet The demand and essence of writing.

Also a kind of and the related prior art of Text region or product --- " point reader " and " write-read machine ", Qian Zheying With off-line identification technology, identification being done to print hand writing and reads the pronunciation of word by loud speaker, the latter applies on-line recogrition, Write complete when, or herein in connection with off-line identification technology, in writing process, or even when just having started to write, institute can be provided The pronunciation of word is write, or even is also read together together with paraphrase.The precondition of word tone can be read before writing does not complete is：Book It is in reeded board or to have the interface for writing of learning to write by tracing over characters printed in red to carry out to write, and inherently belongs to imitating for the formula of learning to write by tracing over characters printed in red.With regard to its skill Be still the positive erroneous judgement based on Text region in terms of electronics for art feature, trained purpose be still " word write to ", and The training ingredient of " word is finished writing " then transfers to mechanical board or interface of learning to write by tracing over characters printed in red undertakes, not its electron assistant training Ability and technical characteristic.

Panoramic auxiliary writing training scheme is made a general survey of, every electron assistant, it is difficult to find to writing skill and technique and level The trace evaluated and fed back, under its training, can only solve the problems, such as " word write to ", and cannot reach cause " word is finished writing ", This does not simultaneously meet the writing training essence requirement for improving and writing attainment and training sturdy grounding in basic skills.Though artificial interactive reaction type training So it is with the obvious advantage and meet writing training essence and it is inherently required, but by teacher's subjective factor and individual difference it is other influence compared with Greatly, high-level, patient calligraphy counselor is such as narrow resources, and not everybody can obtain, also, involve it is artificial, expense and Cost is high, and extraordinary people can bear.

Then, an imagination is just drawn naturally, i.e., realizes that the auxiliary as interactive with teacher writes instruction with electronic intelligence Practice, is conceived to " word is finished writing ", the comment of teacher, guidance, the even crucial interactive element such as demonstration is electronic, intelligent, with Electronic intelligence auxiliary system realizes that teacher gives directions the Core Feature of writing training, and it can be book as master is in side to make the system Training is write great convenience is provided and is effectively supported.With electronic intelligence simulation, the function of imitation calligraphy teacher, advantage is to eliminate The subjective factor of people and individual difference can realize that objective, just, stringent, unified guidance feedback, deficiency are：Lack The active appreciation of people and perceptual evaluation factor, for some streams of consciousness and with individuality formation style, the unwilling book followed the beaten track It writes or the judge of works may lose in accurate, mistake in meaning.But this kind of writing majority exceeds already lays foundation, practices the first of bottom In the grade stage, the advanced stage lifted and distilled is had enter into, in other words, learns the early stage practiced and write, that is, need honestly By standards and norms write stage, with electronic intelligence substitution teacher give directions scheme objectively be set up and it is possible, be based on This, is formed core of the invention thought and technical characteristic.

Invention content

The present invention is to improve, improve writing quality as core, it is therefore an objective to provide a kind of brand-new, comprehensive, thorough electronic type The method and apparatus for assisting writing practising, it is provided in time with the intelligent supplementary means of electronics or computer about writing matter The problem of technical feedback of amount, answer " how writing ", " where is gap ", makes psychology feel uncertain and is able to releasing, skill and technique not Foot is indicated, to solve the critical issue and technology needs of writing training, realizes that the interactive gain of writing training process follows Ring, power-assisted writing level steadily improve.It is specific aim of the present invention, directiveness, complementary very strong, as good teacher and helpful friend accompanies in side, Not depending on people but surpasses the effect of assisting a ruler in governing a country of people, and the cost of writing training is made to be greatly lowered, and convenience greatly improves, and it is richer at Effect.

The object of the present invention is achieved like this：A kind of electronic intelligence auxiliary writing training and analysis and evaluation system, it is borrowed It helps sense to take the photograph device and obtains character image or information, it is characterised in that：Sense is taken the photograph to pair that the written word of device acquisition is transferred with system Answer model patch word do quantization or it is intuitive compare, both provide and to be harmonious metrization evaluation and/or visually compare image, as feedback, use To instruct writing training, improves and write skill and technique and level.

It is described it is mutually right be registration or similarity or alike degree or the distortion factor, the quantitatively evaluating is score value, or is waited Grade or ratio pattern, it is described to do quantization or " comparison " that intuitively compares is that image compares or writing information comparison, it is described The mode that system provides feedback is picture and/or sound, and it is hand input device or digital image dress that device is taken the photograph in the sense It sets or scanner.

The visual comparison chart seems statically and/or dynamically visually to compare image, and the static visual comparison chart seems logical Cross still image output equipment by model paste the comparison image for the written word that word and fidelity obtain or comparison information be presented on it is same can Depending on picture, the dynamic visual comparison chart seems to write the writing of model patch word and written word by dynamic image output equipment to move Draw or multidate information play is presented in same visual interface simultaneously, or by the writing of one of them write animation or multidate information with Another still image or information is presented in same visual interface simultaneously.

The model patch word is used as writing the word or strokes of characters with font of model and Appreciation gist, it is transferred certainly Computer standard fontlib or specification writing character library, or automatic network server is transferred, or transfer from the sense and take the photograph device storage Written word or printed words or casting are carved characters, and the corresponding model patch word is the knowledge that online or off-line handwritten recognition and determination are done to written word Other result word and its standard letter, or linked up in advance through human-computer interaction before comparing, it is regarded as by book by system The word and its font write.

Described image compare be writing image compare or writing other than be left white or blank image compare, described image Compare registration quantitatively evaluating using the ratio of corresponding region as foundation, the region is weighed with pixel number, or with regional edge along The area that is surrounded is weighed, the ratio of the corresponding region is written word and model patch word coincides or corresponding writing region with Ratio or written word in two writing regions between the greater and model patch word coincide or corresponding are left white or clear area Domain and two be left white or white space in ratio between the greater or aforementioned writing regional percentage and be left white or white space The product of ratio or associative operation or function.

It is relative size and the direction that word image is pasted by regulating writing word and model that described image, which compares, makes the two scale phase Comparison under the conditions of, the scale are used to identify the size and Orientation of character image, and the scale is that Chinese character band is cornerwise The external frame of format line or word of sphere of movements for the elephants lattice or part thereof or foreign letter, or mark word size and Orientation Vector or word outer envelope or character contour polygon, or " learning to write by tracing over characters printed in red " formula strokes of characters edge line, institute Scale is stated to import together with model patch word from standard or specification character library, or be manually set, or paste word or book with model Write device acquisition taken the photograph by sense together, or generated through writing pretreatment, writing pretreatment be in the horizontal direction with And vertical or its inclined direction crosses the four of the writing image external frame of word for obtaining surrounding writing to boundary pixel point.

The sense takes the photograph device and obtains character image or information from the desk horizontally or diagonally or vertically placed, described to write Platform is dark material table top or luminous table top or electronic curtain, or includes the device of light transmission table top, light transmission table top The light that backlight screen or projection arrangement are sent out is can pass through, the brightness and/or presentation scale for enhancing writing back light or model patch Word is write to guide.

The sense takes the photograph device on lettering pen.

The system is software or program, or operation has software or the device of program.

The system is connected with mechanical arm, for writing out model patch word, demonstrates as writing.

The present invention is based on the culture promotion that sense is write in word sense and word, core concept is will to feel the written word for taking the photograph device acquisition The model patch word that device acquisition is taken the photograph in prestore with system or sense does that quantization compares or visual image compares, and provides intuitive reflection and writes matter The feedback result of amount or level.It is accompanied in side as obtained a calligraphy counselor, passes through profession, specification, stringent guidance Training, effectively culture promote write standard sense and the aesthetic feeling of writer, and sturdy writing basic training was trained in acceleration.

The acquisition is that fidelity obtains.The fidelity obtains, and to be the word that obtains authentic with reality word or reality word Writing registration of analog image under the conditions of binaryzation digital picture is not less than 50% or the distortion factor is no more than 1%, the coincidence Degree is written word and model patch word coincides or corresponding writing region and written word and model to paste writing region in word relatively large Ratio between person, the reality word are that the basis word being acquired or true write are formed by writing or track or trace Mark.The comparison done in quantization or intuitive comparison is that character feature compares or stroke details compares or dynamic comparison.

Specific implementation mode

Fig. 1 is the technological thought schematic diagram of embodiment 1.Embodiment 1 is to be applied to inventive concept to do phase to written word A kind of scheme of right quantitatively evaluating.With " learning to write by tracing over characters printed in red " formula stroke edge line for presenting model patch word in cornerwise sphere of movements for the elephants lattice 21 20, be used as write prompt and constraint, handwriting 17 be follow model patch word " learn to write by tracing over characters printed in red " formula stroke edge line 20 personal letter and felt Take the photograph the character image that device fidelity is got, blank or to be left white 19 be that model patch word " is learnt to write by tracing over characters printed in red " formula stroke edge line 20 or written word The stroke edge in region or handwriting 17 between the stroke edge of mark 17 and frame with cornerwise sphere of movements for the elephants lattice 21 The region between " learning to write by tracing over characters printed in red " formula stroke edge line 20 of word is pasted with model.Because model pastes the interior of " learning to write by tracing over characters printed in red " formula stroke edge line 20 of word Portion is the writing region of model patch word and is following for hand-written handwriting 17, so " learning to write by tracing over characters printed in red " formula stroke edge of model patch word Line 20 can also be the scale of model patch word, can also be the scale of handwriting 17 either model patch writing.As it can be seen that " retouching It is red " the stroke edge line of formula both may be used as writing, it is also used as scale, this is the various informative property of writing and/or scale A kind of specific manifestation.Written word is had been presented in figure and compares image with the visual of model patch word, and the presentation region of the two is It overlaps.In order to carry out accurately quantitatively evaluating to writing quality, can choose with cornerwise sphere of movements for the elephants lattice 21 as model patch " learning to write by tracing over characters printed in red " formula stroke edge line 20 of word and the common scale of handwriting 17 can also choose " learning to write by tracing over characters printed in red " formula stroke of model patch word Edge line 20 pastes the common scale of word and written word as model, and the scale of model patch word is the pen of its formula of " learning to write by tracing over characters printed in red " in such cases Draw edge line.It overlaps in scale or under the same conditions, with the writing of written word and model patch word and/or corresponding is left white or blank Registration can be used as evaluation writing quality Quantitative Feedback information.It is described corresponding to be left white or blank is corresponding with writing , other than writing, being left white within scale or blank.The registration refers to the pixel that two regions for participating in comparing coincide Ratio in number or area and the two between pixel number or the relatively large person of area." learning to write by tracing over characters printed in red " formula stroke edge line of word is pasted with model 20 to paste the scale of word as model be a kind of extreme case, in the case, model patch writing do not have it is corresponding be left white or blank, therefore It just can only be using writing registration as Quantitative Feedback.The present embodiment system is transferred from computer standard fontlib or specification hand The correspondence word in body character library or outstanding calligraphy work is write as reference and the object compared, that is, is used as model and pastes word, by accurate Technology compare, feed back the registration or alike degree or similarity that written word and model paste word to writer or onlooker or judge Or the distortion factor.It relates to comparison condition since comparing, alignments, compare fineness Railway Project.About comparison condition：Book If there is the Chinese character sphere of movements for the elephants lattice or box that can follow and foreign language format line etc. are used for prompting or identifying writing words position when writing Set, the constraint of size and Orientation, even the only folding line of paper, then, word it is well-behaved write on specified position, write as Suitable size, and proper direction is kept, this inherently writes the important component of attainment and grounding in basic skills, and writes energy Therefore power and horizontal important embodiment strictly judge writing quality, should just be included in such " specification ", and the present invention will mark The constraint of knowledge word size and Orientation is known as " scale ", then, " stringent to judge " is exactly under scale coincidence or the same terms It judges.There is no dominant scale for following when if writing, scale is not present, and must be present in book stealthyly In the idea and control of writer, because facing a blank sheet of paper, it is impossible to Non-precondition or conceive to write on where, to write It just starts to write in the case of at what direction and size writing, then, the autonomous or Free Writing of this no scale is judged, It just needs under the rational guide for judging orientation, determines that an effective scheme, the present invention pass through " writing pretreatment " and obtain The external frame of word of parallelogram pattern, it centainly has the side of two horizontal directions, meanwhile, model patch word is also done similarly " writing pretreatment ", and ensure it is consistent or parallel with the corresponding edge direction of written word, thus by intervene make written word and model Patch word has obtained comparable " scale " simultaneously.Then, so that it may to be compared by scale.The direction of writing is to take the photograph device by sense Defined, in other words, it is exactly that writer needs the direction followed that sense, which takes the photograph device and obtains the direction of word, this judge scheme be with Simplify and compare to be orientated, if the sense of direction of writer is bad or control is indifferent, it is possible to cause relatively low or not The evaluation result that writing quality must be accurately reflected, is hard on but if not fearing, and takes the orientation of encouragement, and can also take makes to compare counterweight Right higher scheme, specifically：Progressive regulating writing word pastes the relative position of word, size and Orientation with model, makes the word of the two Mark registration highest is more than preset threshold value, and using this registration as the evaluation feedback to written word, this scheme is in place It sets, do progressive adjusting comparison in size, three, direction dimension, data processing amount can be relatively large, and Appraisal process can be time-consuming longer, And ignore the influence of writing position, size, direction to writing quality, the evaluation result obtained is the most advantageous to writer, Most incentive.It is the progressive selection for adjusting step-length to the external factor that final appraisal results are affected, i.e.,：Phase is adjusted every time To the least displacement of position, the minimum zoom ratio of relative size is adjusted every time, and adjusts the minimum rotation of relative direction every time Gyration.In short, the condition compared there are three types of scheme, i.e., harsh " scale " scheme simplifies the loose scheme being orientated and encouragement The loose scheme being orientated.About alignments：Mainly there are two major classes scheme, i.e. image comparison and information comparison.Character feature ratio , stroke details is compared and dynamic comparison, can be all included into image or information comparison after all, alternatively, to use this two The technical solution that class compares.Image, which compares, is based on Digital image technology, and comparison can be accurate to pixel, in order to reliable, accurate, clear Writing registration is known on ground, binary image processing can be done to written word and model patch word, to eliminate color, shade and light The disturbing factors such as light and shade.Pixel-level comparison has been the limit of current technical capability, and information comparison can then seem relatively simple With it is more coarse, mainly the mathematical quantity or physical quantity or geometric sense that characterize writing are compared, advantage is simple and efficient, energy It is enough to obtain evaluation result rapid and not complicatedly.Similar to the hospital diagnosis state of an illness, only sees appearance or sees inside clearly by CT machines, Corresponding information comparison scheme is that shape compares and word slice compares.For comparing fineness, one can be integrally given with full word Evaluation locally can also provide evaluation respectively with regard to each stroke or piecemeal or fragment to each word, can also be to multiple full words It is whole to an evaluation, be similar to teacher couple one " big word " 20 words provide it is excellent, good, in, difference or first, second, third, fourth it is total Body is evaluated.The information fineness that the fineness of comparison pastes word with the model that can be transferred is associated with, if model patch word does not have the detailed of each stroke Thin information, the comparison for being difficult to do stroke grade are judged；Meanwhile the evaluation feedback of different fineness to the guidance of writing feedback meaning and It acts on it is also apparent that different, thinner more certain feedback informations of evaluation that compare are more rich, can make which stroke writer knows Write well, which is not finished writing, alternatively, which part write standard in place, which part not to the utmost comply with one's wishes, this for improve improve works as It is so more specific, more effective.But the raising of fineness is compared along with the costs such as data processing amount and respective handling time, resource cost Increase and handle complexity raising.Mutually right by comparing determination, core is to determine word registration, alike degree or similar Degree can be converted to and recognized registration by the relative position and/or size and/or angle of regulating writing word and model patch word It is fixed.The maximum value of registration is 1, that is, is completely superposed；The part that registration is differed with 1, the as distortion factor can also be used to weigh It is mutually right.Mutually right quantization is to carry out quantitative description or expression to mutually right, can be quantitatively accurate or rough.It provides Determining score is the mode of accurate quantification, and hundred-mark system integer fraction or score value usually using full marks for 100 points are such as intended to precision Higher, can retain decimal after hundred-mark system score value, and the decimal digits more at most precision of reservation is higher.Certainly, if wanted to precision It is not very high to ask, and can also use the integer score value of ten point system or 5 points of systems, it is equally possible that retaining decimal, becomes decimal point Value, to improve evaluation accuracy.About decimal score value, the quantitative representation that can be expected naturally further includes：Use pure decimal Or the score no more than 1, such as 0.95 or 3/4ths, etc..Rough further includes quantitatively the mode for providing opinion rating, is usually used It is excellent, good, in, difference or first, second, third, the sequence of fourth indicate grade, can also indicate grade with 1,2,3,4.Ten point system or 5 points of systems Integer score value can also be interpreted as grade.Other than directly giving the evaluation method of score value or grade, it can also use more It visualizes, the patterned fashion of more lively performance ratio or score value or class information.It is usually seen to be presented in computer screen Progress bar, and indicate with the ingredient sector in round the figure of ratio, can be used as quantitative assessment.Pattern also may be used certainly To show grade, such as the icon of battery dump energy on electronic product, the icon of mobile phone WIFI signal intensity is used in music notation Staff indicate scale and statistical graph in vertical bar shape pattern sequence and draw the line parallel with bottom edge in the triangles " pyramid " pattern that section is showed, is all the example of level pattern.Quantization degree of being harmonious intuitively is provided in order to be more clear Evaluation can also be integrated using aforementioned score value, grade and pattern, indicate score value simultaneously such as in " progress bar " pattern, or to " gold Each grade of word tower " shape pattern fills different colours, and the approximation ratio to the limit or pinnacle of a pagoda is showed with color change.If it is The higher situation of fineness is compared, be harmonious metrization evaluation or the grade of each strokes of characters or part can be listed with a table Or pattern is enriched, full and accurate feedback information to keep writer very clear to writing gain and loss and quality condition.In short, Be harmonious metrization evaluation of the written word with model patch word is provided, it is significant to the review of writing, self-examination, improvement, raising.This implementation Example can be the APP applied to smart mobile phone, or run on the program software of handwritten computer, and can also be operation has " word The auxiliary writing training smart mobile phone or handwritten computer of the metrization that is harmonious evaluation " program can also be that taking the photograph device by sense obtains Character image or information, with to written word and model patch word do the metrization that is harmonious compare evaluation system or in which software.

Fig. 2 is the technological thought schematic diagram of embodiment 2.Embodiment 2 is that inventive concept is applied to written word and model Patch word does a kind of scheme intuitively compared.Model pastes writing 16 or together with sphere of movements for the elephants lattice or grid 18 and/or blank or is left white 19 structures At model patch word, handwriting 17 or together with sphere of movements for the elephants lattice or grid 18 and/or blank or it is left white 19 composition written words, it is seen then that institute It includes its writing to state written word or model patch word, can also include its scale and being left white corresponding to writing under the scale simultaneously Or blank.Blank or be left white 19 be on writing substrate adhere to or cover writing after remaining part or region, it is with writing Stroke edge line is boundary, or collectively forms its boundary together with the boundary of scale or writing medium or presentation interface.It can with writing Word is pasted to determine or present written word and model, is left white with scale combination or blank can also realize identical presentation purpose, it is this kind of The relationship being similar between " characters cut in intaglio " and " characters cut in relief " to carve a seal, or " egative film " and " photograph " of flushing photograph is the same.Model is pasted in figure Word and written word are presented in same viewable pictures side by side, and model pastes word and the presentation region of written word is adjacent, as word scale Sphere of movements for the elephants lattice or grid 18 are identical, and such visual comparison image can make that viewer is intuitive, brightly senses based on written word Mark 17 compared to model paste writing 16 mutually right or otherness writing skill and technique and level, thus by body odour, self-examination, self-criticism, It summarizes and improves writing quality.The present embodiment is so-called to be exactly intuitively while being presented on same picture, and written word is presented and model pastes word Picture area can overlap, and can also connect, can be with adjacent, and principle is can and can to see the two simultaneously at a glance.With regard to presenting Can be character image for content, such as authentic image or fidelity image or binary image, can also be text information, such as The external frame of word or word " slice " pattern." slice " generally has multiple or multigroup, and when presentation, written word pastes word pair with model It answers two " slices " at position at one group, presents simultaneously.Either write on electronic handwriting equipment, or on paper and/ Or write on other mechanical media, also either " learn to write by tracing over characters printed in red " or face note or autonomous or Free Writing, written word is taken the photograph into dress through sense Acquisition is set into electronic form, and the electronics that position, size and Orientation is adjustable, controllable, changeable is done with the model of electronics form patch word Formula compares, always valuable and easy-to-use to obtain progress for savouring, introspecting writing.Especially work as book It writes with the non-visual or the two of model patch word alternative one at different interfaces, the two is presented in same visual comparison image just It is more valuable, and meaning and effect are more notable, this is also the huge advantage place of electronic intelligence auxiliary writing training.It is described " non-visual " is not present, is invisible, or not leaving visual ink marks or trace or writing, or in writing visualization or electricity It is more than 50% that distortion and the distortion factor occur during sonization.The process that device obtains character image and information, inherently word are taken the photograph in sense Mark visualization, electronic process, it is objective, accurate evaluation basis and premise that sense, which takes the photograph device fidelity and obtains written word,.Existing Have under technical conditions, the sense for capableing of " fidelity acquisition " takes the photograph what device was readily available, critical issue be acquisition scheme selection and The support and cooperation of software, especially software, which cannot apply acquisition process, may lead to the increased unfavorable intervention of the distortion factor and shadow It rings.The form that the present embodiment visually compares image be it is abundant, can be quiet movable.Both written word and model patch word are static or equal It is moved for dynamic or one quiet one, is all the scheme that can be taken.It is so-called it is " quiet " be that complete word is presented, it is so-called " dynamic " to be It presents and writes dynamic process or writing writing animation.A kind of extreme situation is：Device acquisition written word is taken the photograph in sense and model pastes word Dynamic text process, and provide visual comparison image, it means that the presentation mode of model patch word is write in one's own hand by outstanding writer, Even scene or synchronous demonstration personal letter.For the autonomous or Free Writing of non-imitation, writer is to see in writing process Word is pasted less than model, model corresponding with written word pastes word and specified by writer before writing or after writing, or by system pair Writing process does on-line handwritten recognition determination, and after the completion of writing, writer sees corresponding model patch word, and see its with The visual comparison image oneself just to have been write, even dynamic text or animated image can feel warm, steady and sure, impression depth It carves, this impact force and strong impression can do a great deal of good for writing the promotion of skill, this exactly intuitive meaning visually compared Where value.
