As shown in fig. 1, fig. 1 is a schematic diagram of a hardware structure of a terminal according to an embodiment of the present invention.

As shown in fig. 1, the embodiment of the present invention relates to a terminal, and the terminal may include: a processor 1001, such as a CPU, a communication bus 1002, a memory 1003, and a database 1004. The communication bus 1002 is used for realizing connection and communication among these components, and the database 1004 stores color schemes of the plastic template and colorimetric values corresponding to the color schemes, where the colorimetric values include black-and-white colorimetric values, red-and-green colorimetric values, and yellow-and-blue colorimetric values. The memory 1003 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory). The memory 1003 may alternatively be a storage device separate from the processor 1001. Those skilled in the art will appreciate that the configuration shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

As shown in fig. 1, the memory 1003 as a computer storage medium may include a preparation scheme determination program for the plastic template.

In the apparatus shown in fig. 1, the processor 1001 may be configured to call a preparation scheme determining program of the plastic template stored in the memory 1003, and perform the following operations:

acquiring the performance requirement of a client on the plastic;

In one embodiment, the processor 1001 may call the preparation scheme determining program of the plastic template stored in the memory 1003, and further perform the following operations:

the types of the ingredients and pigments in the target preparation recipe are the same as the types of the ingredients and pigments in the matched preparation recipe, the difference between the mass ratio of the ingredients in the target preparation recipe and the mass ratio of the ingredients in the matched preparation recipe is less than a first preset difference, and the difference between the mass ratio of the pigments in the target preparation recipe and the mass ratio of the pigments in the matched preparation recipe is less than a second preset difference.

the performance requirements include at least one of hardness requirements, transparency requirements, finish requirements, and concealer requirements.

According to the scheme, the terminal obtains the first chromatic value of the plastic template provided by the client, determines the second chromatic value matched with the first chromatic value in the database, and obtains the performance requirement of the client on the plastic, so that the preparation scheme of the plastic template is determined according to the performance requirement and the color scheme corresponding to the second chromatic value. Because the color matching scheme of the prepared plastic sample plate and the chromatic value corresponding to the color matching scheme are stored in the terminal by the plastic manufacturer, the terminal can quickly and accurately determine the color matching scheme of the plastic required by a customer, and then the preparation scheme of the plastic sample plate is obtained according to the determined color matching scheme and the performance requirement, the color matching of the plastic required by the customer is not required according to the experience of workers, the situation that whether the plastic meets the requirement or not is repeatedly confirmed by the customer to prepare the plastic sample plate for multiple times is avoided, and the cost loss of plastic production equipment is low.

Based on the hardware architecture of the terminal, the embodiment of the method for determining the preparation scheme of the plastic template is provided.

Referring to fig. 2, fig. 2 is a first embodiment of a method for determining a preparation scheme of a plastic template according to the present invention, the method comprising the steps of:

step S10, obtaining a first chromatic value of a plastic template, and determining a second chromatic value matched with the first chromatic value in a database, wherein the database stores color schemes of various plastic templates and chromatic values corresponding to the color schemes;

in this embodiment, the execution subject is a terminal. The terminal can be intelligent equipment such as a computer, a mobile phone and the like. And a database is arranged in the terminal, and the color scheme of the plastic sample plate and the chromatic value corresponding to the color scheme are stored in the database. The colorimetric values include a black-and-white colorimetric value L, a red-and-green colorimetric value a, and a yellow-and-blue colorimetric value b. L represents illuminance (luminance), which corresponds to brightness, a represents a range from red to green, and b represents a range from yellow to blue. L ranges from 0 to 120; the value range of a and b is from +120 to-120, wherein, the +120a is red, and the green is changed when the value range is gradually transited to-120 a; similarly, +120b is yellow and-120 b is blue. All colors are composed by alternating changes of these three values. The color matching scheme further comprises various pigments and mass ratios corresponding to the pigments, namely the colorimetric values of the plastic sample plate prepared by mixing the main materials with fixed mass according to the mass ratios corresponding to the pigments are the colorimetric values corresponding to the color matching scheme.

The main material is plastic granules which can be in any color. The color scheme may thus contain the color of the plastic granules of the plastic template. The color of the plastic particles can be any color.

The terminal may be in communication with the spectrometer. The light splitting detector is used for detecting a first colorimetric value of the plastic template provided by a customer. After the light splitting detector detects the plastic template, the chromatic value can be displayed, or the chromatic value is directly sent to the terminal, so that the terminal stores the first chromatic value of the plastic template.

After the terminal obtains the first chromatic value, the terminal traverses the chromatic value of each color scheme in the database to search for a second chromatic value matched with the first chromatic value, wherein the color difference value between the second chromatic value and the first chromatic value is smaller than a preset color difference value, the color difference value comprises a black-white color difference value △ L, a red-green color difference value △ a and a yellow-blue color difference value △ b, and the color difference value △ L between the chromatic value and the first chromatic value of the color scheme is smaller than L₀△ a is less than a₀And the difference value △ b is less than b₀Then, the colorimetric value of the color scheme can be determined as a second colorimetric value, L, matching the first colorimetric value₀For presetting black and white color difference value, a₀Is a preset red-green color difference value b₀To prepareAnd setting a yellow-blue difference value.

Step S20, obtaining the performance requirement of the customer for the plastic;

in this embodiment, the customer has other performance requirements besides the color of the plastic. For example, customers require plastics to be translucent, transparent, or opaque; or the customer requires the hardness of the plastic to reach above the preset hardness; alternatively, the customer may request that the plastic be rough or smooth. That is, the performance requirements include at least one of hardness requirements, transparency requirements, finish requirements, and concealer requirements.

The plastic manufacturer can input the performance requirement of the customer and the customer number in the terminal for correlation storage, and the customer number is consistent with the number of the plastic template. After the second chrominance value is determined, the stored performance requirements of the customer can be obtained according to the number of the plastic template providing the first chrominance value.

And step S30, determining a target preparation scheme of the plastic template according to the performance requirement and the color scheme corresponding to the second chromaticity value, wherein the color scheme corresponding to the second chromaticity value comprises various pigments of the plastic template and mass ratios corresponding to the various pigments.

And after the terminal determines the second chromatic value, the terminal determines the color scheme corresponding to the second chromatic value. The terminal determines the ingredients and the mass ratio of the ingredients according to the performance requirements. For example, if the performance requirement contains a concealing degree requirement, the ingredient is titanium dioxide, and the larger the concealing degree is, the larger the mass ratio of the titanium dioxide is. The terminal can form a preparation scheme of the plastic template according to the mass ratio of the main materials to the main materials, the mass ratio of the ingredients to the auxiliary materials, and the mass ratio of the pigment to the pigment, so that a plastic manufacturer can prepare the plastic template according to the preparation scheme.

In the technical scheme provided by this embodiment, the terminal obtains a first chroma value of a plastic template provided by a client, determines a second chroma value matched with the first chroma value in the database, and obtains a performance requirement of the client on the plastic, so that a preparation scheme of the plastic template is determined according to the performance requirement and a color scheme corresponding to the second chroma value. Because the color matching scheme of the prepared plastic sample plate and the chromatic value corresponding to the color matching scheme are stored in the terminal by the plastic manufacturer, the terminal can quickly and accurately determine the color matching scheme of the plastic required by a customer, and then the preparation scheme of the plastic sample plate is obtained according to the determined color matching scheme and the performance requirement, the color matching of the plastic required by the customer is not required according to the experience of workers, the situation that whether the plastic meets the requirement or not is repeatedly confirmed by the customer to prepare the plastic sample plate for multiple times is avoided, and the cost loss of plastic production equipment is low.

Referring to fig. 3, fig. 3 is a second embodiment of the method for determining a preparation scheme of a plastic template according to the present invention, wherein the step S30 includes:

step S31, determining the ingredients of the plastic sample plate and the mass ratio of the ingredients according to the performance requirements;

and step S32, obtaining the mass ratio of the main materials of the plastic sample plate, and determining a target preparation scheme of the plastic sample plate according to the ingredients, the mass ratio of the main materials and the color scheme corresponding to the second chromaticity value.

In this embodiment, the performance requirement may be a relatively fuzzy requirement. For example, customers only require transparency, opacity, or translucency for transparency. That is, the terminal can determine the ingredients and the mass ratio of the ingredients according to the high, medium and low performance requirements. Different performance requirements correspond to different ingredients. For example, concealer requires the ingredient to be titanium dioxide. And the mass ratio corresponding to the high, medium and low performance requirements decreases in turn.

In addition, the performance requirements vary as the customers require plastics made by the plastics manufacturer to be used for different purposes. For example, if plastic is used for the housing, the performance requirements are high smoothness and concealer; for another example, if plastic is used as a flange for equipment, the performance requirements are corrosion resistance, low requirements for smoothness, and no concealer requirements. It is understood that the performance requirement may be the use of the plastic, and the terminal determines the ingredients of the plastic template and the mass ratio of the ingredients according to the use; that is, the terminal stores the mapping relation table of the plastic usage, the ingredients and the ingredient mass ratio, and the ingredient and ingredient mass ratio of the plastic sample plate can be determined by the plastic usage as the performance requirement.

The main material of the plastic template is plastic particles, and the mass ratio of the main material is generally a fixed value and does not change. And the terminal acquires the mass ratio of the main materials of the plastic sample plate, so that the preparation scheme of the plastic sample plate is formed according to the ingredients, the mass ratio of the main materials and the color scheme corresponding to the second chromaticity value.

In the technical scheme provided by this embodiment, the terminal determines the ingredients of the plastic sample plate and the mass ratio of the ingredients according to the performance requirement, so that the preparation scheme of the plastic sample plate is determined according to the mass ratio of the main materials, the ingredients, the mass ratio of the ingredients, and the color scheme corresponding to the second chromaticity value.

Referring to fig. 4, fig. 4 is a third embodiment of the method for determining a preparation scheme of a plastic template according to the present invention, wherein the step S30 includes:

step S33, determining the performance parameters corresponding to the performance requirements;

step S34, determining a batching scheme matched with the performance parameters in the database, wherein the batching scheme comprises the performance parameters of the plastic template;

and step S35, determining a target preparation scheme of the plastic template according to the ingredient scheme and the color scheme corresponding to the second chromaticity value.

In this embodiment, the performance requirements have corresponding performance parameters. For example, if the hardness of the plastic required by the customer needs to be higher than a certain hardness, the hardness is the performance parameter corresponding to the performance requirement. It is understood that the performance requirements include the performance parameters that are present, or the performance requirements include the performance parameters of the plastic that can be determined. For example, the performance requirement is that the plastic is transparent, and the terminal can determine the performance parameters of the plastic according to the transparency.

And the terminal analyzes according to the input performance requirement so as to determine the performance parameters corresponding to the performance requirement. The database of the terminal stores a lookup table of performance parameters, ingredients and the mass ratio of the ingredients. And the terminal determines the performance parameters, namely the ingredients and the mass ratio of the ingredients can be found in the lookup table according to the performance parameters, and the ingredients and the mass ratio of the ingredients which are found form an ingredients scheme. Of course, various batching schemes can be stored in the terminal, and the batching schemes have corresponding performance parameters; and if the difference value between the performance parameters of the batching scheme and the performance parameters of the performance requirements is smaller than the preset difference value, the batching scheme is the color matching scheme matched with the performance parameters of the performance requirements.

And after the batching scheme is determined, the terminal forms a preparation scheme of the plastic sample plate according to the batching scheme, the color matching scheme and the mass ratio of the main materials.

In the technical scheme provided by this embodiment, the terminal determines the performance parameters corresponding to the performance requirements, and determines the ingredient scheme matching the performance parameters in the database, so as to determine the preparation scheme of the plastic template according to the ingredient scheme and the color scheme corresponding to the second chroma value.

Referring to fig. 5, fig. 5 is a fourth embodiment of the method for determining a preparation scheme of a plastic template according to the present invention, and based on any one of the first to third embodiments, after the step S30, the method further includes:

step S40, determining whether a preparation scheme matched with the target preparation scheme is stored in the database;

step S50, when the database stores the preparation proposal matched with the target preparation proposal, the serial number of the matched preparation proposal and the plastic sample plate of the stock corresponding to the serial number are determined,

step S60, outputting the plastic template of the stock corresponding to the serial number as the prompt information of the plastic template corresponding to the plastic template;

and step S70, when the database does not store the preparation scheme matched with the target preparation scheme, outputting the target preparation scheme to allow a manufacturer to prepare the plastic template corresponding to the plastic template based on the target preparation scheme.

In this embodiment, since the plastic production equipment has a lower limit value for the amount of the plastic to be produced, the plastic production equipment can be started to produce the plastic template when the material for preparing the plastic template reaches the lower limit value. More than ten plastic templates can be produced by one-time material production, and the performance parameters of each plastic template are basically consistent. Therefore, after each time the plastic manufacturer produces the plastic template, the plastic manufacturer will stock the remaining plastic templates. And if other customers have the same requirements, the plastic template in stock is provided for the customers without preparing the plastic template.

In this regard, after determining the target preparation scheme, the terminal searches the database for a preparation scheme that matches the target preparation scheme. Specifically, the terminal determines a first ingredient and a first pigment in a target preparation scheme, and then brushes out a first preparation scheme with the first pigment and the first ingredient from a database; the terminal further determines a first mass ratio of the first ingredients and a second mass ratio of the first pigments; and finally, the terminal determines whether a preparation scheme close to the first mass ratio and the second mass ratio exists in each first preparation scheme, and if so, the terminal can judge that the database stores the preparation scheme matched with the target preparation scheme. The approach to the first mass ratio and the second mass ratio is: the difference between the mass ratio of the pigments of the preparation scheme and the mass ratio of the first pigment in the database is less than the preset mass ratio difference, and the difference between the mass ratio of the ingredients of the preparation scheme and the mass ratio of the first ingredient in the database is less than the preset mass ratio difference. When the terminal judges that the preparation scheme matched with the target preparation scheme is stored in the database, the number of the matched preparation scheme is obtained, and the plastic sample plate corresponding to the number is output as prompt information of the plastic sample plate corresponding to the plastic template, namely, the plastic manufacturer is prompted to adopt the stock plastic sample plate corresponding to the number as the plastic sample plate corresponding to the plastic template provided by the customer.

And when the terminal judges that the preparation scheme matched with the target preparation scheme is not stored in the database, outputting the target preparation scheme to allow a manufacturer to prepare the plastic template corresponding to the plastic template based on the target preparation scheme.

In the technical scheme provided by this embodiment, after the target preparation scheme is determined, the terminal determines whether a preparation scheme matched with the target preparation scheme is stored in the database, and if so, prompts the manufacturer to use the stock plastic sample plate corresponding to the serial number of the matched preparation scheme as the plastic sample plate corresponding to the plastic template, so that the stock plastic sample plate is fully utilized, and the production cost of the plastic production equipment is saved.

Referring to fig. 6, fig. 6 is a fifth embodiment of the method for determining a preparation scheme of a plastic template according to the present invention, and based on the fourth embodiment, after the step S70, the method further includes:

step S80, determining the number of the target preparation scheme and the plastic sample corresponding to the target preparation scheme;

step S90, storing the serial number and the target preparation scheme association in the database.

In this embodiment, after the plastic manufacturer produces the plastic template according to the target preparation scheme, a portion of the plastic template remains. The plastic manufacturer numbers them and inputs the numbers into the terminal.

In the technical solution provided in this embodiment, the terminal obtains the input serial number, and uses the serial number as the serial number corresponding to the target preparation scheme, so that the target preparation scheme and the serial number are stored in the database in a related manner, so that a manufacturer can provide the plastic template corresponding to the target preparation scheme to other customers having the same plastic requirements by using the plastic template corresponding to the target preparation scheme.

In an embodiment, the terminal traverses the color scheme in the database, and stops traversing when finding the second chroma value matched with the first chroma value.

Specifically, the terminal traverses the color schemes according to the arrangement sequence of the color schemes in the database. The arrangement order may be the size of the color scheme numbers or the morning and evening of the storage time of the color schemes. The terminal selects a color matching scheme to be matched from a database as a current color matching scheme, and then calculates each color difference value between the first chromaticity value and the chromaticity value of the current color matching scheme, wherein each color difference value is a black-white difference value delta L, a red-green color difference value delta a and a yellow-blue difference value delta b.

If each color difference value is smaller than the corresponding preset color difference value, that is to say△ L is less than L₀△ a is less than a₀And the difference value △ b is less than b₀And then, the color difference value of the current color scheme is the second chroma value matched with the first chroma value. At this time, the terminal stops traversing the chromatic value of the color scheme in the database.

If at least one color difference value is larger than or equal to the corresponding preset color difference value, it can be determined that the chromatic value of the current color scheme is not matched with the first chromatic value, and the terminal needs to traverse the chromatic values of other color schemes which are not traversed in the database. And then, the terminal determines the current color scheme from the color schemes which are not selected as the current color scheme in the database, and returns to the step of calculating the color difference values between the first chromaticity value and the chromaticity value of the current color scheme, thereby judging whether the chromaticity value of the current color scheme is matched with the first chromaticity value.

In one embodiment, where there are many color schemes stored in the database, a terminal traversing color scheme chromaticity values one by one may increase terminal traversal time. In this regard, when storing the color scheme, the chromaticity label of the color scheme may be determined according to the chromaticity value of the color scheme.

Specifically, the terminal determines the value of the black-and-white colorimetric value L, and determines the label corresponding to the black-and-white colorimetric value according to the value, for example, if L is less than 50, the plastic template is white, and if L is greater than or equal to 50, the plastic template is black. The terminal determines the value of the red-green colorimetric value a, and determines the label corresponding to the red-green colorimetric value according to the value, for example, if a is a + value, the plastic sample plate is red, and if a is a-value, the plastic sample plate is green. And finally, the terminal determines the value of the red-green chroma value b, and determines the label corresponding to the yellow-blue chroma value according to the value, for example, if b is a + value, the plastic sample plate is yellow, and if b is a-value, the plastic sample plate is blue. The three labels constitute the color scheme's chromaticity labels, which are, for example, black, red, and yellow.

The terminal determines the first chromaticity label of the plastic template according to the first chromaticity value, and the determination manner of the first chromaticity label refers to the above description, which is not repeated herein. The terminal searches for the second chromaticity label matched with the first chromaticity label in the database, namely the first chromaticity label is the same as the second chromaticity label, so that the color schemes corresponding to the second chromaticity labels are screened out from numerous color schemes to be used as the color schemes to be matched, and the searching amount of the terminal is greatly reduced. And the terminal selects the current color scheme from the color schemes to be matched so as to determine a second chroma value matched with the first chroma value.

In the technical scheme provided by this embodiment, the terminal determines the first chromaticity label corresponding to the first chromaticity value, and determines the color scheme corresponding to the second chromaticity label matched with the first chromaticity label as the color scheme to be matched in the database, so that the workload of searching the color scheme of the second chromaticity value matched with the first chromaticity value by the terminal is greatly reduced.

In an embodiment, the terminal obtains a predetermined color difference value corresponding to the first chrominance value, that is, the predetermined color difference value is L₀、a₀And b₀. And the terminal determines a first preset color difference value in each preset color difference value. And the terminal determines a first color scheme meeting a first preset color difference value in the database, namely determines the color scheme with the color difference value between the chromatic value and the first chromatic value smaller than the first preset color difference value as the first color scheme. For example, the first predetermined color difference value is L₀The terminal will have all △ L less than L₀Is determined as the first color scheme.

After the first color scheme is determined, the terminal determines a second preset color difference value from the preset color difference values which are not selected as the first preset color difference value, and then determines a second color scheme meeting the second preset color difference value from the first color scheme. The second predetermined color difference value is different from the first predetermined color difference value, e.g., the first predetermined color difference value is L₀If the second predetermined color difference value is a₀Or b₀. The first color scheme satisfying the second predetermined difference may be determined as the second color scheme, i.e. the chromaticity value of the second color scheme and the first color difference value are smaller than the second predetermined color difference value, e.g. the second predetermined color difference value is a₀Then △ a is less than a₀Is a second color scheme.

And after the second color scheme is determined, the terminal takes the last preset color difference value as the remaining preset color difference value, so that the second color scheme meeting the remaining preset color difference value is determined as the third color scheme. For example, the remaining predetermined color difference value is b₀Then △ b is less than b₀Is a third color scheme. And finally, determining the chromatic value of the third color scheme as a second chromatic value matched with the first chromatic value.

It is understood that the color difference value between the chromatic value and the first chromatic value of the color scheme is smaller than the preset color difference value, that is, the color scheme is determined to satisfy the preset color difference value.

In one embodiment, the terminal matches the first color value with each color scheme in the database to determine the color schemes for which the first color value matches.

And displaying all the matched color schemes and the chromatic values of the color schemes by the terminal, so that the manufacturer views each color scheme and the chromatic values of the color schemes. The manufacturer may compare the first chromaticity value of the plastic template with each displayed chromaticity value, thereby selecting a target color scheme among the plurality of color schemes.

Each color scheme displayed by the terminal is provided with a corresponding selection button, and if the fact that the selection button is clicked is detected, the terminal can be regarded as detecting the selection operation of the color scheme. And the terminal determines the chromatic value of the color scheme corresponding to the selected operation as the second chromatic value matched with the first chromatic value, namely the chromatic value of the color scheme of the clicked selection key is used as the second chromatic value matched with the first chromatic value.

In one embodiment, the terminal may calculate the total color difference value according to the black-and-white color difference value, the red-and-green color difference value, and the yellow-and-blue color difference value, specifically, the total color difference value △ E²＝△L²+△a²+△b²That is, the predetermined formula is △ E²＝△L²+△a²+△b². And after the terminal obtains each color difference value corresponding to the second chromatic value, bringing each color difference value into a preset formula, thereby calculating to obtain a total color difference value corresponding to the second chromatic value.

The size of the total color difference value can reflect the difference between the plastic template stored in the database and the plastic template provided by the customer, and the larger the total color difference value is, the more obvious the difference between the two is. The terminal may determine the color scheme corresponding to the second chroma value smaller than the preset total chroma value as the target color scheme of the plastic template.

In one embodiment, people are more sensitive to black and white colors. Therefore, the terminal needs to determine the target color matching scheme of the plastic sample plate by combining the black and white difference value and the total color difference value.

Specifically, after determining the total color difference value corresponding to each second chroma value, the terminal determines each first color scheme with the total color difference value smaller than the preset total color difference value. And the terminal determines the black-white difference value corresponding to each first color scheme, and further determines the first color scheme with the black-white difference value smaller than the preset black-white difference value as the target color scheme corresponding to the plastic sample plate. It is understood that the total color difference value between the chromatic value of the target color scheme and the chromatic value of the plastic template is smaller than the preset total color difference value, and the black-white difference value is smaller than the preset black-white difference value.

Specifically, after determining the total color difference value corresponding to each second chroma value, the terminal determines each second color scheme with a black-white difference value smaller than a preset black-white difference value. And the terminal determines a second color scheme with the total color difference value smaller than the preset total color difference value and determines the second color scheme as a target color scheme corresponding to the plastic sample plate. It is understood that the total color difference value between the chromatic value of the target color scheme and the chromatic value of the plastic template is smaller than the preset total color difference value, and the black-white difference value is smaller than the preset black-white difference value.

In one embodiment, the terminal determines the smallest total color difference value among the respective total color difference values. And the terminal judges whether the minimum total color difference value is smaller than a preset total color difference value or not.

And if the minimum total color difference value is smaller than the preset total color difference value, determining the color scheme corresponding to the minimum total color difference value as the target color scheme of the plastic sample plate, and determining the color scheme with the minimum difference from the plastic template as the target color scheme of the plastic sample plate.

In one embodiment, there is still a slight difference between the second chrominance value and the first chrominance value. Therefore, the plastic template prepared according to the color scheme of the second chromaticity value is not necessarily the plastic required by the customer. In this regard, the terminal may adjust the second chromaticity value to obtain a plurality of color schemes to be determined. The second chromatic value is adjusted to be a black-white chromatic value, a red-green chromatic value and a yellow-blue chromatic value, and the adjustment amplitude is small, namely the adjustment of the second chromatic value by the terminal is fine adjustment. The fine adjustment can be characterized by that each color difference value between the chromatic value and the second chromatic value of the color scheme to be determined is smaller than a corresponding preset threshold value, and the color difference values comprise a black-white color difference value, a red-green color difference value and a yellow-blue color difference value.

The second chromaticity value may be fine-tuned a plurality of times, each fine-tuning resulting in one color scheme to be determined. And performing one up-adjustment and one down-adjustment on the second chromatic value to obtain two color schemes to be determined in consideration of cost. And the terminal determines the color scheme to be determined and the color scheme corresponding to the second chromatic value as the target color scheme and displays each target color scheme, so that the manufacturer can prepare different plastic sample plates according to different target color schemes. And mixing the various pigments in the target color matching scheme, the corresponding mass ratios of the various pigments and the pre-prepared plastic particles by a plastic manufacturer to obtain a mixed material, and putting the mixed material into plastic production equipment to prepare a plastic sample.

And the plastic sample plate prepared according to the down-regulated color scheme is a lower limit plastic sample plate, the plastic sample plate prepared according to the up-regulated color scheme is an upper limit plastic sample plate, and the plastic sample plate prepared according to the unadjusted color scheme is a middle limit plastic sample plate.

In an embodiment, the preset adjustment value is stored in the terminal, and the preset adjustment value is an absolute value, and the preset adjustment value includes a preset adjustment value corresponding to a black-and-white chromatic value, a preset adjustment value corresponding to a red-and-green chromatic value, and a preset adjustment value corresponding to a yellow-and-blue chromatic value.

After the terminal determines the second chromatic value, acquiring a preset adjustment value, and accordingly increasing the corresponding preset adjustment value of the black-white chromatic value, the red-green chromatic value and the yellow-blue chromatic value in the second chromatic value to obtain a third chromatic value; and then, correspondingly reducing preset adjustment values of the black-white chromatic value, the red-green chromatic value and the yellow-blue chromatic value in the second chromatic value to obtain a fourth chromatic value.

And the terminal determines the color scheme to be determined corresponding to the third chroma value and the color scheme corresponding to the fourth chroma value.

In an embodiment, the terminal stores a look-up table of the mass ratio of the black-white colorimetric value, the red-green colorimetric value and the yellow-blue colorimetric value to the pigment. Specifically, the numerical value of the black-white colorimetric value is divided into a plurality of intervals, each interval of the black-white colorimetric value corresponds to the pigment and the pigment ratio, the numerical value of the red-green colorimetric value is divided into a plurality of intervals, the numerical value of the yellow-blue colorimetric value is divided into a plurality of intervals, and one interval of the black-white colorimetric value, one interval of the red-green colorimetric value and one interval of the yellow-blue colorimetric value correspond to the mass ratio of the pigment to the pigment. After the terminal obtains the third chroma value, the terminal can determine respective intervals according to the black-white chroma value, the red-green chroma value and the yellow-blue chroma value of the third chroma value, so that the pigment and the mass ratio of the pigment are determined in the lookup table according to the three intervals. An interval may be a range of values or may be a specific number. The lookup table is obtained by arranging the pigment, the pigment mass ratio and the chromatic value required by plastic cement preparation of a plastic cement manufacturer, and the lookup table is stored in the terminal.

For example, the terminal may determine the third chroma value according to the third chroma value and the look-up table, and the terminal may determine the first pigments and the mass ratios of the first pigments according to the third chroma value and the look-up table, where the plurality of first pigments are different, so as to form the color scheme to be determined corresponding to the third chroma value according to the mass ratios of the first pigments and the third pigments. Similarly, after the terminal determines the fourth chroma value, the mass ratio of the second pigments and the mass ratio of the second pigments are determined according to the fourth chroma value and the lookup table, so that the color scheme to be determined corresponding to the fourth chroma value is formed according to the mass ratio of each second pigment and each second pigment.

In an embodiment, after determining the third chroma value and the fourth chroma value, the terminal may determine a color scheme matching the third chroma value in the database, and determine a color scheme matching the fourth chroma value, where the specific determination scheme refers to a process in which the terminal determines a color scheme of the second chroma value matching the first chroma value in the database, which is not described herein again.

After the terminal determines the color scheme with the third chroma value and the fourth chroma value matched, the matched color scheme can be determined as the color scheme to be determined.

In one embodiment, when the second chrominance value is adjusted, the terminal needs to determine the adjustment amount according to the specific value of the second chrominance value. Specifically, assuming that the chromatic value of black and white is 50, i.e. the plastic is more clear in black and white, even if the adjustment amount of the chromatic value of black and white is smaller, the change of black and white of the plastic is more obvious, therefore, the adjustment amount is smaller between 30-60 of the chromatic value of black and white, and can be slightly larger than 30-60 of the chromatic value of black and white. It will be appreciated that the second chrominance values differ in value and by the amount of adjustment. The terminal stores the interval of each colorimetric value and the increment value and decrement value corresponding to the interval, the interval tends to be neutral color (the proportion of the two colors is not large, such as black and white color, red and green color and yellow and blue color), and the increment value and decrement value are small. While the interval tends to be a certain color, the increment value and decrement value corresponding to the interval may be slightly larger, for example, the chromaticity value of red and green is +100, and tends to be red, and the increment value and decrement value are slightly larger, and the variation of the shade of red on the plastic is not very large. It should be noted that, the absolute values of the increment value and the decrement value corresponding to the interval are both smaller than the preset value, so as to ensure that the second chrominance value is finely adjusted.

And the terminal determines increment values and decrement values corresponding to the black-white chromatic value, the red-green chromatic value and the yellow-blue chromatic value according to the second chromatic value, so that the second chromatic value is increased according to each increment value to obtain a third chromatic value, the second chromatic value is reduced according to each decrement value to obtain a fourth chromatic value, and the color scheme to be determined corresponding to the third chromatic value and the fourth chromatic value is determined. The determination of the color scheme to be determined refers to the above description, and is not repeated herein.

In one embodiment. The light splitting detector is used for detecting a second chromaticity value of the plastic sample plate. The beam split detector can display the second chromaticity value after the plastic sample plate is detected, or directly sends the second chromaticity value to the terminal, so that the terminal stores the second chromaticity value of the plastic sample plate.

It should be noted that the plastic template is prepared from a target color scheme determined by the manufacturer according to the first chromaticity value of the plastic template provided by the customer. The terminal stores color schemes corresponding to the multiple plastic sample plates and chromatic values corresponding to the color schemes, determines the target color schemes of the plastic sample plates according to the chromatic values of the plastic templates, and then prepares the plastic sample plates according to the target color schemes.

The terminal determines a black-white difference value, a red-green difference value and a yellow-blue difference value between the second chrominance value and the first chrominance value, and determines a total color difference value between the second chrominance value and the first chrominance value according to the black-white difference value, the red-green difference value and the yellow-blue difference value, wherein the color difference values comprise a black-white difference value △ L, a red-green difference value △ a and a yellow-blue difference value △ b, and a total color difference value △ E²＝△L²+△a²+△b²And after the terminal obtains each color difference value between the second chroma value and the first chroma value, substituting each color difference value into a formula, thereby calculating to obtain the total color difference value between the second chroma value and the second chroma value.

The size of the total color difference value can reflect the difference between the prepared plastic template and the plastic template provided by the customer, and the larger the total color difference value is, the more obvious the difference between the two is. And after the total color difference value is obtained through calculation, judging whether the total color difference value is larger than a preset total color difference value, if so, judging that the difference between the prepared plastic template and the plastic template provided by the customer is larger, namely the preparation of the plastic template fails. And then, the terminal acquires each color scheme to be determined corresponding to the target color scheme. And the manufacturer takes one matched color scheme as the target color scheme to prepare the plastic sample plate. And if the currently prepared plastic sample plate fails, preparing the plastic sample plate by adopting other determined color matching schemes.

The terminal re-determines the target color scheme among the various color schemes to be determined. It should be noted that the newly determined target color scheme is different from the previous target color scheme, i.e., the color scheme of the currently prepared plastic template is not included in each color scheme to be determined. And after the terminal re-determines the target color scheme, outputting the re-determined target color scheme for the manufacturer to prepare the plastic sample plate according to the re-determined target color scheme.

In one embodiment, after saving each color scheme to be determined, the terminal may assign a corresponding priority to each color scheme to be determined. Specifically, the plastic template prepared by each color scheme to be determined is theoretically less different from the plastic template. The difference between the plastic template and the plastic template is determined through the total color difference value and the black-white difference value between the plastic template and the plastic template, so that the weight corresponding to the total color difference value and the black-white difference value is given, the black-white difference value and the total color difference value of the color scheme to be determined are weighted and calculated according to the weight, and the reference value of each color scheme to be determined is obtained. The smaller the reference score, the least difference between the plastic template and the plastic template is indicated. And the terminal carries out the priority of the color scheme to be determined according to the reference score, and the smaller the reference score is, the higher the priority of the color scheme to be determined is.

And after determining the priority of each color scheme to be determined, the terminal stores the color schemes to be determined in association with the priority. When the plastic sample plate prepared by the target color scheme is greatly different from the plastic template, the terminal acquires each color scheme to be determined and the priority of each color scheme to be determined, so that the color scheme to be determined with the highest priority is re-determined as the target color scheme, and the plastic sample plate is prepared again.

In one embodiment, the customer provides the manufacturer with a plastic template, and then obtains a first chromaticity value of the plastic template through the spectrometer. And color schemes of a plurality of plastic templates and chromatic values corresponding to the color schemes are stored in the terminal.

And the terminal determines a color scheme matched with the first chromatic value in the database, and adjusts the second chromatic value of the color scheme to obtain a plurality of color schemes to be determined. And the terminal outputs the color scheme to be determined and the color scheme corresponding to the chromatic value, so that the manufacturer can prepare a corresponding plastic sample plate for each output color scheme.

It should be noted that, the size of the total color difference value can reflect the difference between the plastic template stored in the database and the plastic template provided by the customer, and the larger the total color difference value is, the more obvious the difference between the two is. Therefore, the total color difference value between the chromatic value of each color scheme output by the terminal and the first chromatic value is smaller than the preset total color difference value, that is, the total color difference value between the color difference value of the prepared plastic sample plate and the color difference value of the plastic template is smaller than the preset total color difference value.

After preparing a plurality of plastic templates, placing the plastic templates and performance data of the plastic templates in a sample delivery file, wherein the performance data comprises chromatic values, hardness, transparency, smoothness and concealing parameters of the plastic templates. The manufacturer distributes the sample file to the client, so that the client can confirm the sample file according to the plastic template in the sample file and the performance parameters of the plastic template. After the customer confirms, the customer fills confirmation information in the confirmation area of the sample sending file, and then returns the confirmed sample sending file to the manufacturer.

The terminal determines the target plastic template confirmed by the customer in the sample file. The terminal can determine the target plastic template according to the confirmation information in the sample sending file input by the manufacturer. In addition, the terminal also has an optical character recognition function. The terminal collects the image of the plastic sample plate confirmation area in the sample sending file, so that binarization processing is carried out on the image, the binarization processed image is identified through an optical character identification function so as to identify character information in the image, and the target plastic sample plate is determined according to the character information.

In one embodiment, the customer has other performance requirements in addition to the color requirements for the plastic. For example, customers require plastics to be translucent, transparent, or opaque; or the customer requires the hardness of the plastic to reach above the preset hardness; alternatively, the customer may request that the plastic be rough or smooth. That is, the performance requirements include at least one of hardness requirements, transparency requirements, finish requirements, and concealer requirements.

The plastic manufacturer can input the performance requirement of the customer and the customer number in the terminal for correlation storage, and the customer number is consistent with the number of the plastic template. After determining the first colorimetric value of the plastic template, the terminal may obtain the stored performance requirement of the customer according to the serial number of the plastic template providing the first colorimetric value. And the terminal determines the ingredients and the mass ratio of the ingredients according to the performance requirement so as to form an ingredient scheme, and stores the ingredient scheme. For example, if the performance requirement contains a concealing degree requirement, the ingredient is titanium dioxide, and the larger the concealing degree is, the larger the mass ratio of the titanium dioxide is.

And after the terminal determines the target plastic sample plate, the terminal obtains the color scheme matched with the plastic template and the stored color scheme, and then determines the identity of the client. The identity may be the name, code number, etc. of the customer. Specifically, each sample sending file has a corresponding number, and the number can be an identification of the client. The terminal collects the serial numbers of the sample sending files through the camera, and accordingly the identity of the client is determined according to the serial numbers. And finally, the terminal stores the color matching scheme, the ingredient scheme and the identity in an associated manner.

In one embodiment, the detection system comprises a detection platform, an image acquisition module and a terminal. The terminal is the control center. The detection platform is used for placing the plastic finished products provided by the customers, and the image acquisition module is used for acquiring images of the plastic finished products. The image acquisition module can be a camera, and the image acquisition module can rotate to gather the finished plastic product's of different angles image.

The manufacturer can place the plastic finished product on the detection platform and input the detection instruction on the terminal. At this time. The terminal starts the image acquisition module to acquire the detection platform image and identifies the image so as to determine whether the plastic finished product is placed on the detection platform. If the detection platform is provided with the plastic finished product, the terminal controls the image acquisition module to acquire images of the plastic finished product at different acquisition angles. The collection angle is an angle between a plane where a camera of the image collection module is located and a plane where the detection platform is located, each collection angle is a preset collection angle, and the terminal obtains images of the plastic finished products at different collection angles.

After the terminal obtains a plurality of images, the terminal pulls out the plastic finished product in each image through built-in pulling out software to the plastic finished product that pulls out is spliced to the collection angle that corresponds based on different images, thereby founds the off-the-shelf space model of plastic. In addition, when the plastic finished product is detected to be positioned on the detection platform, a client corresponding to the plastic finished product is determined, and therefore whether a space model of the plastic finished product provided by the client is stored or not is determined in the system. If not, the image acquisition module is controlled to acquire the images of the plastic finished product at different acquisition angles so as to form a space model of the plastic finished product. If yes, directly extracting the space model of the plastic finished product provided by the customer.

After the terminal obtains the space model of the plastic finished product, the region with smaller planeness of the plastic finished product can be analyzed from the space model, and the region with smaller planeness is determined as the intercepting region. The distances between the plane formed by the boundary of the intercepting region and the points on the intercepting region are smaller than the preset distance, namely the flatness of the characteristic intercepting region is smaller. Specifically, the terminal may use the detection platform as a reference surface to construct a three-dimensional space coordinate, and then convert the coordinates of each pixel point of the plastic product in the image into the three-dimensional space coordinate through a conversion formula between the pixel coordinate and the real coordinate, so that each point on the space model of the plastic product has a corresponding space coordinate. And the terminal can determine the intercepting area according to the space coordinates of each point on the space model. For example, the terminal acquires all points with the same height on the spatial model, the points form a plane, the points of the spatial model higher than the plane form a region, and the distance between the highest point in the region and the plane is smaller than a preset distance, which indicates that the flatness of the region is small and can be used as a capture region.

The space model is actually equivalent to the plastic product on the detection platform. After the terminal determines the intercepting area, each point of the boundary of the intercepting area can be determined, and each point has a corresponding space coordinate. The terminal can be provided with a transmitter of monochromatic visible light, the transmitter can move, and the terminal can move by controlling the transmitter to send the monochromatic visible light to the space coordinates of each point, so that the intercepted area is marked. The terminal can set up a plurality of transmitters, marks the intercepting region through monochromatic visible light of each transmitter transmission to make the measurement personnel carry out the entity mark in this region on to the plastic finished product according to monochromatic visible light, also promptly to intercepting regional marking off mark, thereby carry out the intercepting of plastic template to this intercepting region.

In one embodiment, the terminal selects three reference points from each point on the spatial model representing the plastic product, the three reference points are not on the same straight line, that is, the three reference points are connected to form a plane, and the plane is defined as a reference plane.

And the terminal connects the three reference points to obtain a reference plane, and then cuts the space model along the reference plane to obtain an area corresponding to the reference point, wherein the area forms a curved surface.

The terminal then determines the spatial coordinates of each point on the region, and the determination manner of the spatial coordinates refers to the above description, which is not repeated herein. And the terminal determines the space coordinates of each point on the reference plane according to the space coordinates of the three reference points, so that the distance between each point on the area and the reference plane can be calculated, wherein the distance refers to the height of the point relative to the reference plane.

And the terminal acquires the maximum distance again and judges whether the maximum distance is smaller than or equal to the preset distance.

When the maximum distance is less than or equal to the preset distance, the flatness of the area can be judged to be close to zero, namely the area can be used as an intercepting area to intercept the plastic template.

When the maximum distance is larger than the preset distance, the flatness of the area can be judged to be larger, and the area is not suitable for intercepting the plastic template. In this regard, the terminal reselects three reference points among the points on the spatial model, and the reference plane formed by the reselected reference points cannot be parallel to or overlap with the previous reference plane. So that the terminal determines the cutting area on the plastic finished product again.

It should be noted that the plastic template needs to cover the small hole of the spectroscopic detector, so the area of the intercepting region for intercepting the plastic template needs to be larger than the preset area, and the preset area is larger than the area of the small hole. Therefore, when the terminal determines the three reference points, a reference plane formed by the three reference points needs to be larger than a preset area, so that the area of the intercepting region is larger than the preset area (the intercepting region is a curved surface, and the area of the curved surface is larger than the reference plane). In addition, in order to facilitate the terminal to calculate the area of the reference plane, three reference points selected by the terminal form a right triangle, the right triangle has a unique circumscribed circle, and the external interface forms the reference plane (boundary points on the reference plane are points on the space model). Therefore, the hypotenuse of the right triangle is the diameter of the circumscribed circle, the area of the circumscribed circle can be calculated through the diameter, the length of the hypotenuse of the right triangle limited by the terminal is larger than or equal to the preset length, and the preset length is determined according to the preset area.

The invention further provides a terminal, wherein color schemes of a plurality of plastic templates and chromatic values corresponding to the color schemes are stored in the database, the terminal comprises a memory, a processor and a preparation scheme determining program of the plastic templates, the preparation scheme determining program of the plastic templates is stored in the memory and can be operated by the processor, and when being executed by the processor, the preparation scheme determining program of the plastic templates realizes the steps of the preparation scheme determining method of the plastic templates.

The present invention also provides a readable storage medium storing a preparation scheme determining program for a plastic template, wherein the preparation scheme determining program for the plastic template, when executed by a processor, implements the steps of the preparation scheme determining method for the plastic template according to the above embodiments.
