(first embodiment)

Below, the determining method of the visual information of the mating information of the coating of multi-colour pattern of first embodiment of the present invention and base material is elaborated.Fig. 5 is the flow chart of determining method of visual information that is used to explain mating information and the base material of the coating of multi-colour pattern that has used system shown in Figure 1.In following explanation; Treating apparatus 101 is accepted observer's (designer etc.) operation and the processing carried out; Be in inner arithmetic element (following note the is made CPU) record cell (hard disk drive etc.) internally predetermined data to be read in the inner temporary (following note is made memory); With the processing that memory carries out as the working region use, CPU suitably is recorded in result in the record cell.

In step S1, prepare determination object thing 104, operate image-input device 103 by the observer, the image on the surface of determination object thing 104 is taken into treating apparatus 101 as electronic data (multi-color decorative pattern image).Determination object thing 104 is to have multi-color decorative pattern on its surface, has promptly distributed atypic colored particles and the object of the decorative pattern that forms.So, in being taken into the multi-color decorative pattern image of handling in the device 101 (electronic data), have spot as stated.Be taken into the multi-color decorative pattern image of handling in the device 101 and be the graph image that the surface of building etc. is given.And in the present invention, the object that has formed the decorative pattern of flow coat that kind on the surface is not used as the determination object thing.In addition, also can obtain the material data that becomes electronic data via communication lines such as internets uses.

Here, do not limit the preferred data mode that adopts in sRGB (standard RGB) space though the form of electronic image data is special.The international standard of the sRGB color space that to be IEC (International Electrotechnical Commission (IEC)) formulate in October, 1998 is a standard of having confirmed not have the form of expression of the dependent color of type.The electronic image data can be conduct and the L of the approaching table look form of people's visual resulting impression from the sRGB formal transformation ^*a ^*b ^*Form, its conversion method be owing to be known, and (in fact, being to be the XYZ form from the sRGB formal transformation, is L from the XYZ formal transformation more therefore to omit explanation ^*a ^*b ^*Form).The color space of sRGB is compared with other color space; The narrow range of the color that can show; Be difficult to show rightly emerald green, darkcyan, orange, cerise or yellow etc.; Yet at the internal and external ornament with building is in the field of coating of purpose, owing to do not adopt the high color of these colourities, therefore can not become problem.

In step S2, the visual information of the colored particles of decision multi-color decorative pattern formation coating and the visual information of base material.Specifically, the operating unit of observer's operational processes device 101, such decision as follows is used for utilization and brushes the color of the colored particles of reproducing the spot of all kinds on the multi-color decorative pattern image (electronic data) and the color of base material.

At first, the multi-color decorative pattern image that treating apparatus 101 will be obtained in step S1 is shown in display unit 102 as coloured image, accepts the operation of operating portion.The size of multi-color decorative pattern image to display, shape are (for example 1 limit are the square of 256 pixels) arbitrarily.Then, when observer's operating operation unit (for example pressing the button of computer), on the multi-color decorative pattern image that is shown during the specified position with mouse; Treating apparatus 101 decisions are the regulation zone at center with specified position; To the visual information of the whole pixels in this zone, promptly rgb value averages, and resulting mean value is assumed to the sRGB value; Convert the XYZ value into, convert L then into ^*a ^*b ^*Value.At last, treating apparatus 101 uses resulting L ^*a ^*b ^*Value and be recorded in the visual information of a plurality of colour atlas in the record portion in advance, i.e. color data, decision and resulting L ^*a ^*b ^*Be worth immediate colour atla, promptly determine L ^*a ^*b ^*The minimum colour atla of geometry distance (aberration) Δ E in the space.The every specified of observer position, treating apparatus 101 are all carried out these processing repeatedly.So,, then can determine the colour atla corresponding with each spot of different colours if the observer on the multi-color decorative pattern image that is shown on the display unit 102, specifies the interior pixel of spot of certain color rightly.That is, can determine to be used to reproduce color and the color of base material of colored particles of the coating of spot.As a rule,, comprise base material, determine 3～4 kinds of colors by an image.For later processing specifies to step S3; Here; Suppose spot, determined that base material is that a kind of color, colored particles are the colour atla (colour atla 0 is corresponding to material, and colour atla 1～3 is corresponding to colored particles) that amounts to four kinds of colors of three kinds of colors corresponding to four kinds of colors.

In addition, in (a) of Fig. 2, represent to ask the example in regulation zone of the mean value of rgb value with square.In the regulation zone; As a rule using on one side is the zonule in the four directions of 10～20 pixels, yet, so long as the zone that is contained in basically in the spot on the multi-color decorative pattern image gets final product;, be 8～256 pixels for example Yi Bian can make for foursquare situation.In addition, in the conversion of color form, can use known toCIEXYZ as the canonical function of JAVA (registration mark) language.Perhaps also can use on the internet (http://www005.upp.so-net.ne.jp/fumoto/linkp25.htm) disclosed function.

The coating that colour atla can use Japanese coating TIA distribution is with the Standard Colors schedule of samples etc.Also can use DIC color guide, Munsel colour atla etc. in addition.The color card table of Japanese coating TIA is because the color card when being to use coating, therefore preferred especially its colour atla.

In addition, for color space (chromatic diagram), though be described L near visual sensation ^*a ^*b ^*Form, however be not limited thereto, also can use RGB, Lab, HSI etc.

In said explanation; Although clear observer utilizes visual situation of specifying the position that is used to determine representative color; Yet also can be shown in Fig. 2 (b); Analyze the RGB, HSI of whole pixels of multi-color decorative pattern image etc., utilize image to handle to lose lustre processings (minimizing of tonal gradation number is handled), extraction representative color.In addition; It also can not the color of from image, selecting colored particles; But the color of color, colored particles that preestablishes a plurality of base materials is similar to the color retrieval, the color of decision base material and the color of colored particles as reference colour from whole pixels of image.

Can be according to the actual measurement reflectivity and the KS value of look material of the colour atla of the color card that determined numbering, the CCM that the KS theory of Kubelka-Munk has been used in use calculates the cooperation ratio of look material.And, in following explanation, not method, but cooperate the method for ratio to be elaborated asking according to the multi-color decorative pattern view data to known CCM.

Then, in step S3, treating apparatus 101 is obtained the representative color of spot, i.e. the area ratio of the representative color of colored particles.Specifically, at first, with expression and representative color, be the variable N of the number of the approximate colored particles of colour atla j (j=1～3) _jThe initial value of (j=1～3) is made as " 0 ".After this, select a pixel of multi-color decorative pattern image, RGB converts L into this pixel value ^*a ^*b ^*, calculate resulting L ^*a ^*b ^*L with determined each colour atla j in step S2 ^*a ^*b ^*The aberration Δ E of value.After this, determine the minimum colour atla j of aberration Δ E among a plurality of colour atla j (j=1～3), with the variable N of this colour atla j _jAdd 1, as new variable N _jIf the whole pixels to the multi-color decorative pattern image are carried out these processing, then variable N _j(j=1～3) just become the number of the approximate pixel of the representative color of color and each colored particles.After this, calculate and whole pixel count N _AllRatio (N _j/ N _All), obtain the area ratio of the spot (colored particles) in the image.This area ratio (N _j/ N _All) be the mating information (cooperation ratio) that multi-color decorative pattern forms each colored particles in the coating.When the size distribution of supposing colored particles, proportion were all identical for which kind of color, area ratio was directly proportional with the number of colored particles.

In said explanation, though use the minimum colour atla of the aberration Δ E ratio of quadraturing, as other method, also can obtain each pixel of multi-color decorative pattern image and the aberration Δ E of colour atla, it is carried out " weighting " and obtains area ratio.As a kind of " weighting " method, also can calculate at L ^*a ^*b ^*The L of determined colour atla in the color space ^*a ^*b ^*L with each pixel ^*a ^*b ^*Aberration Δ E, accumulative total Δ E below the setting, for example Δ E is at the number of the pixel below 3, decides the mating information (cooperation ratio) of each colored particles according to this aggregate-value.So just can be more approaching visual impression ground cooperates the color of image and decides as coating.

As another kind of " weighting " method; For with the said pixel of aberration Δ E below setting of likewise obtaining; On Δ E, multiply by the contribution coefficient corresponding with Δ E; Resulting value is added up, decide the mating information (match ratio) of each colored particles, so also can according to this aggregate-value.For example, if Δ E≤1 then makes contribution coefficient=1, if Δ E=1～3 then make contribution coefficient=0.8, if Δ E>=3 then make contribution coefficient=0.2.So also can be more approaching visual impression ground cooperates the color of image and decides as coating.

Processing through above step S1～S3; The colour atla of base material and each colored particles and the area ratio of each colored particles have been obtained; Therefore in the step shown in following; Use resulting these information to generate coating of multi-colour pattern, utilize simulation to estimate under situation about being painted on the base material whether can obtain required multi-color decorative pattern.

In step S4, specify the condition of simulation.For example, the observer considers the result of step S1～S3, with quality ratio, the amount of colored particles and the size of colored particles of color, vehicle and the colored particles of the color of base material, colored particles, through operating unit input processing device 101.Provided an example of input picture among Fig. 6.Among Fig. 6, base material is bg, and the colored particles of three looks is c1～c3.The color of colored particles is with rgb value, and promptly each Red with 8 (0～255), Green, Blue import.The quality ratio of vehicle (playing the material of the effect of " slurry ") composition and colored particles is specified in the scope of vehicle/colored particles=60/40～70/30, is generally 65/35.In the coating of reality, consideration appearance of film and performance are come the total amount of regulation colored particles, so the amount Haigo of colored particles specifies with the cooperation ratio (%) with respect to total amount.The big or small Dia of colored particles all is appointed as 10.0 (pixels) for three kinds of colors.And because colored particles will cover base material or other colored particles that overlapped fully, so the turbidity hase of coating is appointed as 100 (%).

For the color of colored particles, can directly import rgb value as stated, also can import the colour atla numbering.Among Fig. 6, in the color hurdle, shown the colour atla numbering (C15-75B, C25-90A etc.) of the coating of Japanese coating TIA distribution with the Standard Colors schedule of samples.That is,, then also can automatically set corresponding Red, Green, Blue if specify the colour atla numbering.

In step S5, treating apparatus 101 uses the information of in step S4, importing to come the noise of the color of drawing colouring particle.Here; Be set at corresponding to the result among step S1～S3, in step S4, imported vehicle/colored particles=65/35; The color of colored particles is the rgb value of brown, white, grey three looks, has imported palm fibre/white/ash=12/26/62 as amount (cooperation ratio) separately.And palm fibre/white/ash=12/26/62nd is counted N with each colored particles of in step S3, obtaining _jThe ratio of (j=1～3) is approaching, amount to the combination of 100 real positive value.So, be not limited to illustrative positive integer value here, also can be the value that comprises the position below the decimal point.

Fig. 7 representes the photo of actual colored particles.It is following such colored particles, that is, be in the pigmented finiss of color arbitrarily to using the coloring pigment slurry with water-based reaction-curable crylic acid resin coating (white) toning; Add mosanom; Splash in the calcium hydroxide aqueous solution, stir the back and filter the colored particles that modulates thus.Owing to be such particle, therefore can substrate (surface of base material) be covered.Can know that from Fig. 7 colored particles is unsetting particle, its size is indefinite, and the distribution of size is wide.Fig. 8 is that expression is measured the particle diameter of actual colored particles and the chart of the size distribution that obtains.According to instrumentation result shown in Figure 8, can't be that the diameter of particle is depicted as the noise on the base material in the colored particles below the 0.2mm through visual identification.Like this, have CG describe to handle accelerate and the texture of image more near the actual advantage of filming.

With reference to Fig. 9, the processing of describing noise is specified.At first, shown in Fig. 9 (a), treating apparatus 101 is described the color of base material with given size.Then, treating apparatus 101 is selected a kind of color (colour atla j) in the middle of the colored particles of three looks, decision the rgb value that will describe.Then, treating apparatus 101 is selected a pixel randomly on the image of base material color, will to the processing that selected pixel is set the rgb value of colour atla j carry out repeatedly with image in the corresponding number of times of number of this colored particles.For example; In size of images is under the situation of 512 pixels * 512 pixels; For brown colored particles, (vertical pixel count) * 512 (horizontal pixel count) * 0.35 of describing 512 randomly the ratio of total pixel number (total colored particles number with) * 0.12 ratio of the amount of total colored particles (amount of each colored particles with) 11010 pixels of ≈.Likewise, describe the noise of the individual grey of noise, 56885 (≈ 512 * 512 * 0.35 * 0.62) of the individual white in 23855 (≈ 512 * 512 * 0.35 * 0.26) at random.(b) of Fig. 9 is the image of having described the state of noise to the colored particles of a color.

Originally should that kind as shown in Figure 8, only the spot of diameter below 0.2mm described as noise.But; Of the back, because diameter is described as polygon (being coated with full) greater than the spot of 0.2mm, therefore to describe the situation of circle (being coated with full) little for the area ratio of the actual spot of being described; So, describe the noise of the amount corresponding with whole granule numbers of each colored particles in order to remedy this difference.Experiment is found,, obtain " area of having described noise " to a kind of colored particles of color, makes preferably as stated, to be set at the area of the area described with circle=describe with polygon+described the area of noise:

The ratio of the total pixel number of the number=integral image of the noise of describing * total colored particles number and amount with the amount of total colored particles of ratio * each colored particles of total pixel number.

Owing to use a plurality of (being brown, white, grey three looks) colored particles here; Therefore the noise from the few colored particles of use level begins to describe successively; Do not have the situation of noise crested of the colored particles of the many colors of use level, thereby can obtain image near the actual impression of filming.So, preferably describe noise here with brown, white, grey order.

Then, in step S6, treating apparatus 101 utilizes CG to obtain according to the information of importing among the step S4 to be used to describe the condition of diameter greater than the colored particles of 0.2mm.After in the generation of CG image of the step S7 that states, use the multithreading of JAVA (registration mark) language, describe the colored particles of multiple color simultaneously.That is, adopt the plotting method that has used as JAVA (registration mark) multithreading of known technology (with reference to pp.97～109 of " Java is handbook on top of " (the U.S. tree work in high fields, technology review society puts down in May, 16)).It is following method; Promptly; To handle as the thread of computer program unit with corresponding the describing of carrying out with spray gun with a brushing of spraying brushing and make, the thread of the number similar number of preparation and spray gun is being described when carrying out a plurality of threads synchronously.And, though actual coating of multi-colour pattern is a kind of coating that has mixed the colored particles of multiple color,, in this simulation, simulation utilizes the brushing of a plurality of spray guns to generate the CG image.

The condition of describing is the stand-by period ST, the size distribution of particle that each thread is described of color (rgb value), each thread of coating of number (corresponding with coating number, number of colours), each thread of used thread.The color of the number of thread, the coating of each thread is directly used the data of being imported among the step S4.Stand-by period ST is the calculating as following of the amount of quality ratio, colored particles according to the vehicle (vehicle) in step S4, imported and colored particles.In addition, in the size distribution of the particle of being described, use logarithm normal distribution.

At first, obtain the area ratio (%) of the colored particles of each thread according to the vehicle of in step S4, importing and the quality ratio of colored particles, the amount of colored particles (cooperating ratio).For example; Under the situation of vehicle/colored particles=65/35, palm fibre/white/ash=12/26/62; If the supposition colored particles does not overlap ground orientation from the teeth outwards, then the area of the colored particles of grey can be thought 0.35 * 0.62=0.217 (21.7%) with the ratio of the area of integral image.But in fact, colored particles overlaps.In addition, as stated, fine particle (particle diameter is below 0.2mm) is described as noise, so the area ratio of describing in the processing afterwards should be less than 21.7%.The instrumentation result who films according to reality can know, preferably will be multiply by 0.6 value that obtains according to the area that specified cooperation is inferred in step S4 as area ratio.

So, for example the area of the colored particles of grey is set at 0.35 * 0.62 * 0.6=0.1302 (13.02%) with respect to the area ratio of integral image.Likewise, the area of brown, white colored particles is set at 0.0252 (=0.35 * 0.12 * 0.6) (2.52%), 0.35 * 0.26 * 0.6=0.0546 (5.46%) respectively with respect to the area ratio of integral image.

Then, calculate the stand-by period ST of each thread according to the area ratio (%) of colored particles.So-called stand-by period ST is meant, after having described with a kind of color inside to be coated with the polygon (will narrate in the back for polygonal generation) of having expired from a thread, up to describing the next polygonal time, specifies with msec (millisecond) usually.If stand-by period ST is short, then the polygonal number described of time per unit will become many, can describe intensive colored particles image, and is then opposite if the stand-by period is long, can describe sparse colored particles image.Specifically, obtain formula 1 in advance, use it to decide stand-by period ST as regression equation.

Y=ax ^b(formula 1)

Here, x is the area ratio (%) of colored particles, and y is stand-by period ST (msec).

In addition, the regression coefficient a of formula 1, b be with the size of colored particles accordingly with little, in, big three models obtain in advance.

Little: be the situation of particle diameter (pixel)≤7,0.1≤average grain diameter (mm)≤0.5, the formula of being obtained when using particle diameter to be 5 pixels

In: be 7 < particle diameter (pixels) < 15,0.5 < average grain diameter (mm) < 1.5 situation, the formulas of being obtained when using particle diameter to be 10 pixels

Greatly: be the situation of particle diameter (pixel)>=15,1.5≤average grain diameter (mm)≤3, the formula of being obtained when using particle diameter to be 20 pixels

Figure 10 is the expression curve of describing the relation of area ratio x that the polygon that size is 10 pixels (D=10) (will narrate in the back about polygonal generation) obtained in 60 seconds and stand-by period ST (" in " situation of model).Curve by Figure 10 can know, obtained the regression equation y=e of regression coefficient a=4.41, b=-1.01 ^4.41X ^-1.01Coefficient correlation is up to R ²=0.996, have very strong correlation, the repeatability of the regression equation of explanation formula 1 is good.

Then, as the size distribution of the particle that will describe, ask logarithm normal distribution.When utilizing CG to describe polygonal region repeatedly; For example in being depicted in step S4 during the polygon of the size of specified colored particles; If moderately change the distance R on center and polygonal summit on one side; Describe with the distribution of approaching actual size distribution of brushing on one side, then can be near actual multi-color decorative pattern.The result who studies various particle diameters distributions and obtain is that logarithm normal distribution is the most approaching actual distribution that is coated with brush board.When utilizing the CG image to realize logarithm normal distribution, as long as decide the polygonal shape that to describe according to following order.

At first; Utilize the normal distribution of record in pp.152～153 of known algorithm (" the algorithm dictionary of JAVA " (the fine man of virtue and ability in village grade difficult to understand, technology review society, put down in May, 15) to produce algorithm); Produce the variable f of normal distribution (mean value=0, standard deviation=1), shown in 2, calculating with variable f is the exp (f) of index; It multiply by exp (0.5); Then with its big or small Dia that multiply by colored particles specified in step S4, generate into the size distribution of logarithm normal distribution, i.e. conduct becomes the granular size g of the variable of logarithm normal distribution.

G=Dia * exp (f)/exp (0.5) (formula 2)

Then, use the granular size g that generates by formula 2, the polygonal center that will describe by formula 3 decisions and the distance R on polygonal summit.

R=0.5 * g (formula 3)

Here, the relation of following formula 4 is arranged between the normal distribution of average value mu=0, standard deviation=1 and the logarithm normal distribution, coefficient exp (0.5) is used for the mean value of logarithm normal distribution is adjusted into 0 coefficient.

Expected value=exp (μ+σ of logarithm normal distribution ²/ 2)=exp (0+1/2)=exp (0.5)=1.64872 (formula 4)

In step S7, use the parameter (size distribution of the particle that the stand-by period ST of the color of the number of thread, the coating of each thread, each thread, each thread are described) that determines through above calculating to carry out CG and describe.Promptly; Started multithreading; Each thread (corresponding with each colored particles) is in each stand-by period ST; Produce the number n (n is the natural number more than 3) on polygonal summit and the position coordinates at center, use formula 2 and formula 3 generate the distance R of n one-tenth logarithm normal distribution, use the rgb value overwrite of the coating of each thread to be the pixel data in n the polygon of R from center distance to the limit.

With reference to Figure 11, polygonal describing specified.Actual colored particles is atypic, can also think that in addition filming after brushing deforms when forming.So, in multi-color decorative pattern is filmed, become atypic polygon.So, in this step S7, describe polygon.That is, utilize same random function to generate the polygonal centre coordinate that to describe,, generate a shape n at random polygon with probability to each n limit shape appointment.For example, the probability with 1/3 generates triangle (n=3), and the probability with 1/3 generates quadrangle (n=4), and the probability with 1/3 generates pentagon (n=5) (with reference to (a) of Figure 11).In addition, if the number n on polygonal summit determine, then use formula 2 and formula 3 to generate the distance R of n one-tenth logarithm normal distribution.In Figure 11 (b), n=4 representes the distance R from center O to tetragonal each summit with L1～L4.In addition, decision n is the position coordinates of R with the distance at center, is the pixel of inboard of the n limit shape on summit to being positioned at a determined n position, sets the rgb value of the coating of each thread.(c) of Figure 11 is the image of the multi-color decorative pattern that generates like this.And here, because the decision at random through the distance R at an appointment and center of the position on the summit of n limit shape, the polygon of therefore being described is not necessarily convex polygon.So owing to also have concave polygon or limit that the polygonal situation of intersecting takes place, therefore the inboard of so-called n limit shape is meant at least by 3 limit area surrounded.

Carry out so successively and describe to handle, the data on the VRAM are shown in display unit 102 as the CG image.Treating apparatus 101 stops the execution of each thread constantly being transfused under the situation of the instruction of describing to stop arbitrarily, and the rest image in this moment is shown in display unit 102 as multi-color decorative pattern.Stopping of describing for example both can be indicated the operation of operating unit by the observer, and the time after also can the limit record describing to begin, the limit is described, and after having passed through the predefined time, automatically makes it to stop.

In step S8, whether the pattern of the multi-color decorative pattern of the CG image that the observer utilizes is that visual judgement is described in step S7, be shown in display unit 102 is near oneself the imagination (impression).If near observer's the imagination (impression), then treating apparatus 101 is accepted observer's operation, stops the simulation of the described CG of utilization, describe reference record in record portion with what use at last, transfer to step S9.If the observer does not approve this pattern, then treating apparatus 101 is accepted indication, gets back to step S4, to simulate once more.At this moment, can compare, estimate the pattern of the multi-color decorative pattern of the CG image that is shown in display unit 102 with the multi-color decorative pattern image on the surface of determination object thing 104 itself or the determination object thing 104 that in step S1, obtains.

Utilize above a succession of processing, just can and cooperate ratio based on the color of the color of base material, colored particles, the generation coating of multi-colour pattern utilizes the CG image to envision through brushing the multi-color decorative pattern that it obtains and films.

(second embodiment)

Below, the determining method of the visual information of the mating information of the coating of multi-colour pattern of second embodiment of the present invention and base material is described.The structure of employed computer system is identical with Fig. 1.In addition, represent that the flow chart of summary situation of processing of second embodiment is identical with Fig. 5, comprise the processing identical with first embodiment.That is, the processing of the step S1 of second embodiment～S5 is identical with described first embodiment.So, here their explanation is omitted, and later processing describes to the step S6 different with first embodiment.

In second embodiment, in step S6, treating apparatus 101 is obtained according to the information of in step S4, importing and is used to utilize CG to describe to represent the condition of diameter greater than the figure of the colored particles of 0.2mm.After in the generation of CG image among the step S7 that states, for to describe to represent the figure of colored particles to use random number with the corresponding frequency of ratio of the number of colored particles.

The condition of describing does, (i) color of colored particles (describing look), the (ii) corresponding relation of the size distribution of the colored particles of every kind of color (by the particle diameter decision of colored particles), the random number (stating after the details) that (iii) generated and the color of colored particles.In the middle of these conditions, the color of colored particles, the particle diameter of colored particles directly use the value of in step S4, importing.Random number and the corresponding relation of the color of colored particles can use in step S4, import, vehicle and the quality ratio of colored particles and the amount of colored particles (cooperating ratio), as following explanation, calculate.The size distribution of the particle that describe in addition, is used logarithm normal distribution.

Figure 12 is the flow chart of the processing of expression step S6.At first, in step S61, utilize formula 5 to obtain the total N of the colored particles of all categories that will describe _r

N _rThe ratio of the pixel count * colored particles of=integral image * execution efficient * coefficient (formula 5)

Here, the number of so-called colored particles is not a pixel count, but the number of the figure of being described, and the ratio of so-called colored particles is the colored particles in step S4, imported and the quality ratio of vehicle.

Introduced in the formula 5 " execution efficient " be because; In the brushing of reality; Colored particles is distributed in the inside of filming, and be not that whole colored particles all is positioned at surface (multi-color decorative pattern with reference to Fig. 4 is filmed), and fine particle (particle diameter is below 0.2mm) can't be identified as colored particles through visual.For fine particle (particle diameter is below 0.2mm), in step S5, be depicted as noise.Can know according to experimental result, preferably carry out efficient=0.6.

In addition, " coefficient " is image and the actual parameter that is coated with the difference of brush board that is used to adjust the multi-color decorative pattern of being described.Utilize visual image and the actual brush board that is coated with of relatively describing a plurality of patterns and obtaining, the result finds, best coefficient=0.4.

For example, if N is then being described under the situation of foursquare image that 1 limit is 512 pixels in the quality ratio of colored particles and vehicle=0.35 (vehicle/colored particles=65/35) _r=512 * 512 * 0.35 * 0.6 * 0.4 ≈ 22020.

In step S62, judge whether the particle diameter Dia of each colored particles of in step S4, setting is identical, if all be identical value, then transfer to step S63, if any one difference is arranged, then transfer to step S64.

Under the color the situation how particle diameter of colored particles is all identical, because the individual percentage of colored particles is (with respect to the total N of the figure of being described _rRatio) equal area ratio, therefore in step S63, the individual percentage of colored particles is set at the cooperation ratio of pairing colored particles.

With the difference of color under the condition of different, in step S63, obtain the individual percentage of colored particles accordingly at the particle diameter of colored particles with the area ratio of 1 colored particles.When to reality be coated with brush board and image through describing to obtain, represent the magnitude relationship of colored particles with pixel unit, for example during the concerning of large, medium and small Three Estate, find to be about following scope.

Small particle diameter≤7 (being actually 0.1≤average grain diameter (mm)≤0.5)

In 7 < particle diameter≤15 (being actually 0.5 < average grain diameter (mm)≤1.5)

Big particle diameter>15 (being actually 1.5 < average grain diameter (mm)≤3.0)

So, following decision like this each average grain diameter, i.e. average diameter.

Little average diameter=5

Middle average diameter=10

Big average diameter=15

At this moment, the ratio of 1 average area of each colored particles does, little/in/big=5 ²/ 10 ²/ 15 ²=0.25/1/2.25.So, with the cooperation ratio α of the colored particles of i of all kinds _iWith the β corresponding in these area ratios with particle diameter _jValue is removed (α _i/ β _j), obtain resulting merchant's summation S, obtain the ratio (α of each merchant and this summation S _i/ β _j)/S is as the individual percentage of colored particles.

Provide an example below particularly.For example; In vehicle/colored particles=65/35; Palm fibre/white/ash=26/12/62, the particle diameter Dia of the colored particles of specified brown, white, grey is categorized as respectively under the situation of middle or small, big value among the step S4, and the merchant of brown colored particles is 26/1=26.Likewise, the merchant of the colored particles of white, grey is respectively 12/0.25 ≈, 48,62/2.25 ≈ 28.So, brown individual percentage is set at 26/ (26+48+28) ≈ 0.26.Likewise, the individual percentage with white, grey is set at 48/ (26+48+28) ≈ 0.47,28/ (26+48+28) ≈ 0.27 respectively.Here can suitably carry out the processing that rounds of result of calculation.

And the classification of the size of 1 colored particles is not limited to described 3 grades (large, medium and small), also can be divided into 4 more than the grade.In addition, the benchmark with particle size classification also is not limited to said value (under the situation that is categorized as 3 grades, being 7,15 pixels).

Then, in step S65, according to the individual percentage of the colored particles of in step S63 or S64, obtaining, the relation of the random number that decision produces when describing and the color (describing look) of the colored particles of correspondence.That is, with the individual percentage β of the colored particles of color i _iThe scope r of the random number that pro-rata is accordingly produced _Min～r _Max, determine and describe the scope of look random number corresponding.

Below specifically provide an example.For example; In described step S63 (situation that particle diameter is identical); The individual percentage of the colored particles of brown, white, grey is determined to be 0.26,0.12,0.62 respectively; In 0.0～1.0 scope, produce under the situation of uniform random number, can be with doing with the scope decision of respectively describing the look random number corresponding

Brown scope 0.0≤r≤0.26 with random number r

White scope 0.26 with random number r r≤0.38 (=0.26+0.12)

Grey is with scope 0.38 < r≤1.0 of random number r

In addition; For example in described step S64 (particle diameter condition of different); The individual percentage of the colored particles of brown, white, grey is determined to be 0.26,0.47,0.27 respectively; In 0.0～1.0 scope, produce under the situation of uniform random number, can be with doing with the scope decision of respectively describing the look random number corresponding

Brown scope 0.0≤r≤0.26 with random number r

White scope 0.26 with random number r r≤0.73 (=0.26+0.47)

Grey is with scope 0.73 < r≤1.0 of random number r

In addition, as long as pro rata distribute accordingly, also can be the scope beyond the said scope with the scope of respectively describing the look random number corresponding with a percentage.For example, in the example of said step S63, also can with the scope of the lower limit that comprises random number 0.0 corresponding with white and determine do,

White is with scope 0.0≤r≤0.12 of random number r

Brown scope 0.12 with random number r r≤0.38 (=0.12+0.26)

Grey is with scope 0.38 < r≤1.0 of random number r

Can also determine to do,

White is with scope 0.0≤r≤0.12 of random number r

Grey with the scope 0.12 of random number r r≤0.74 (=0.12+0.62)

Brown scope 0.74 < r≤1.0 with random number r

In addition, also can not continuous zone with the scope of respectively describing look random number corresponding r.For example, also can be as follows, brown scope with random number is divided into 2.

Brown scope 0.0≤r≤0.10 with random number r

White scope 0.10 with random number r r≤0.22 (=0.10+0.12)

Brown scope 0.22 with random number r r≤0.38 (=0.26+0.12)

Grey is with scope 0.38 < r≤1.0 of random number r

In addition, about the logarithm normal distribution of using as the size distribution of the particle of being described, since identical with first embodiment, explanation therefore omitted.

In step S7, use parameter through above calculating decision (in the describing of colored particles size distribution, the random number that is generated of every kind of color of used color, colored particles and describe the corresponding relation of look) to carry out CG and describe.That is, the total N with the colored particles that will describe is carried out in following a series of processing (A)～(E) repeatedly _rCorresponding number of times (N _rInferior),

(A) in 0.0～1.0 scope, produce uniform random number

(B) according to random number r that is produced and corresponding relation (in described step S6, the determining) decision of describing look and describe look (rgb value)

(C) position coordinates at generation polygonal summit number n (n is the natural number more than 3) and center

(D) use with (B) in decision describe look corresponding particle diameter Dia, by the distance R of formula 2 and n one-tenth of formula 3 generations logarithm normal distribution

(E) with on image-region randomly the point of decision be the center, be used in the pixel data in describing of being determined in (D) n the polygon that the look overwrite is R from center distance to the limit.

Here, the polygonal center that is determined in (E) is as long as decide through the uniform random number that produces in 0.0～1.0 the scope.For example, be the situation of the foursquare image of 512 pixels for 1 limit, can use the random number r that is produced ₁, will be no more than r ₁The integer value of * 512 (pixels) is used the random number r that is produced then as the X coordinate ₂, will be no more than r ₂The integer value of * 512 (pixels) is as the Y coordinate.

In addition, describe about polygonal, identical with first embodiment, therefore omit explanation.

In step S8, whether the pattern of the multi-color decorative pattern of the CG image that the observer utilizes is that visual judgement is described in step S7, be shown in display unit 102 is near oneself the imagination (impression).If near observer's the imagination (impression), then treating apparatus 101 is accepted observer's operation, stops the simulation of the described CG of utilization, describe reference record in record portion with what use at last, transfer to step S9.If the observer does not approve this pattern, then treating apparatus 101 is accepted indication, gets back to step S4, to simulate once more.At this moment, can compare, estimate the pattern of the multi-color decorative pattern of the CG image that is shown in display unit 102 with the multi-color decorative pattern image on the surface of determination object thing 104 itself or the determination object thing 104 that in step S1, obtains.

Utilize above a series of processing, just can and cooperate ratio based on the color of the color of base material, colored particles, the generation coating of multi-colour pattern utilizes the CG image to envision through brushing the multi-color decorative pattern that it obtains and films.

Though more than first and second embodiment of the present invention is illustrated, the present invention is not limited to described embodiment.

For example, in said explanation, though following situation is illustrated; Promptly; After the visual information of the spot that has determined multi-color decorative pattern, in step S4, the observer considers the result of step S3; Input corresponding simulating condition (mass ratio of the color of base material, the color of colored particles, vehicle and colored particles, the amount of colored particles and the size of colored particles), however also can determine these conditions automatically.After this, also can use the simulated conditions of automatic decision to describe the CG image, after the evaluation of having accepted the observer, as required, the part of slight modification simulated conditions is described the CG treatment of picture once more repeatedly.

In addition; Can consider multiple multi-color decorative pattern is decided as standard decorative pattern color card (following note is made reference colour); The multi-color decorative pattern that sale can be reproduced them forms with coating (compo); In addition, it is also conceivable that the color or the mixed proportion of each colored particles in these reference colours are slightly adjusted that the multi-color decorative pattern of processing new wound forms uses coating.If using the present invention in such cases, the multi-color decorative pattern that then can simulate new wound at an easy rate forms uses coating.

In addition; Even do not have under unsatisfied situation at decorative pattern to reference colour; Through using the present invention; Also can easily determine to reproduce the cooperation of coating of the multi-color decorative pattern of the tone different (for example in the multi-color decorative pattern that comprises white, black and peach granite, pink is changed to blueness, make black white reverse) with reference colour.

In addition, under the situation of carrying out these customizations, though can in very wide scope, change the simulated conditions of multi-color decorative pattern,, in fact preferably simulated conditions are restricted to the scope that can reproduce as coating.In addition, also can limit simulated conditions according to the mode that does not generate the factitious CG image of colour harmony.Therefore, for example if with the variables such as number of the color of the number of the color of colored particles, each colored particles, each colored particles be limited in they corresponding respectively prescribed limits in.

In addition, original image is not limited to the multi-color decorative pattern image, the image arbitrarily (picture with scenes, intaglio plate photo, abstract painting etc.) that also can use the user to like.For example, can apply the present invention to image is arbitrarily implemented that image is handled and the image that obtains determines a plurality of colors (coating) and their cooperation.

In addition, implement also can use the present invention under the situation such as interior trim of multi-color decorative pattern in the inside (specific rooms such as hotel, hotel, office) of building.In this case,, carry out the processing identical, can generate the three-dimensional CG image that the regulation wall has been decorated with multi-color decorative pattern with said step S5～S7 through to regulation wall by the decision of the three-dimensional structure data of object.In addition, also can utilize said step S5～S7 to generate the multi-color decorative pattern image of two dimension in advance, to the regulation wall, generate three-dimensional CG image through its is shone upon (mapping).
