Description

METHODS OF DERIVATION OF CAMOUFLAGE PATTERNS AND PRINTING RECIPES SATISFIED THROUGH THE RANGES OF VISIBLE AND INFRARED LIGHTS, AND CAMOUFLAGING FABRICS MANUFACTURE THEREBY}

The present invention relates to a method for calculating the dyeing prescription for each pattern of the camouflage pattern that satisfies the camouflage conditions of the visible-near-infrared region and to a camouflage fabric manufactured therefrom, and more specifically, to camouflage in a digital image secured from the natural environment (S11). To determine the camouflage pattern that satisfies the camouflage conditions of the visible-near-infrared region under given natural environment conditions by substituting the visible visual digital pattern (S12) and replacing it with the spectral database of the pre-constructed natural-visible-near-infrared region. The spectrum for each pattern is determined (S13), and color matching is performed on the pattern representing the spectrum of the visible-near-infrared region (350 nm to 1200 nm) that matches the spectrum of the determined camouflage pattern to calculate a prescription combination necessary for printing on the fabric (S14). Method of calculating the staining prescription for each pattern of the camouflage pattern satisfying the camouflage conditions of the visible-near infrared region It relates to a camouflage fabric produced therefrom.

In the technical field aimed at achieving conventional camouflage, reports on camouflage articles that can avoid near-infrared wavelengths, that is, fabrics that can be converted into clothing or equipment, such as jackets, backpacks, ballistic vests and boots, are dominant. Publications 83-2624 and 83-2624.

For camouflage in the near-infrared region that is virtually invisible, techniques have been made to closely match the reflectance of a camouflage article or equipment with the near-infrared reflectance of the surrounding environment.

Specifically, each topographical element has a different reflection signal based on its chemical composition, for example, leaves (main components of the forest environment) have relatively low reflectance in the visible region and relatively high reflectance in the near infrared region. On the other hand, sand, which is a major component of desert environments, and concrete, which is a major component of urban environments, have relatively high reflectance in the visible region and low reflectance in the near infrared region.

It is also known that synthetic polymeric polyamides and polyester fibers have very high reflective properties in the 400-2000 nanometer (nm) region. As a result, the near-infrared reflectance of the polyamide and polyester garments and equipment should be adjusted to more closely match the near-infrared reflectance of the environment, and this adjustment of the near-infrared reflectance substantially hides the garment and the equipment, which, in turn, It should be avoided when viewed using implied devices such as implied goggles or image amplification transducers.

For example, Korean Patent Publication No. 2008-86494 discloses a dyeing fabric manufactured to have visible and near infrared differential signals, and has a substantially single color appearance in the visible light (VIS) spectrum and a gastrointestinal appearance in the near infrared (NIR) spectrum. Fabrics have been reported. However, since the present invention has a single color in the visible light reflectance spectrum, the camouflage is limited to the near-infrared (NIR) spectrum according to a pigment or an additive that adjusts the near infrared reflectance characteristics while the stomach is substantially insufficient during the day. It just provides an appearance.

However, in addition to the gastrointestinal tract in the near-infrared region, in particular, the camouflage should be camouflaged under visible light conditions during the day, and at night, the gastrointestinal tract may be observed even when using a recently developed near-infrared telescope (the near-infrared wavelength range 700 to 1200 nm). It should be possible.

Nevertheless, it is not possible to provide an accurate basis for what type of pattern and color is suitable for camouflage under visible light conditions. In other words, since the pattern and color of the camouflage are different depending on the surrounding gastrointestinal environment, the method of objectively inducing the optimal camouflage pattern (shape and color) according to the surrounding environment has not been presented. I can't.

Furthermore, in order to be able to camouflage under a night near infrared telescope, the reflective properties of the dye-dyed fabric pattern used in the daytime camouflage pattern selected above should be the same as the natural environment under night and near infrared conditions. There is no technique for obtaining a camouflage pattern to satisfy the camouflage conditions at the same time.

It is an object of the present invention to provide a method for calculating the dyeing prescription for each pattern of the camouflage pattern that satisfies the camouflage conditions of day and night at the same time in a given natural environment.

Another object of the present invention is a camouflage fabric prepared from color matching by prescription of the pattern color from a plurality of dye groups to implement the printing on the fabric to satisfy the day and night camouflage conditions simultaneously for each pattern of the camouflage pattern To provide.

In order to achieve the above object,

Step (S14); provides a method of calculating the dyeing pattern for each pattern of the camouflage pattern that satisfies the camouflage conditions of the visible- near infrared region.

Therefore, more preferably, in the method for calculating the pattern of dyeing for each pattern of the camouflage pattern of the present invention, the step S13 corresponds to the same color of the visible area digital pattern determined in the step S12, in the visible-near-infrared region of natural products. In contrast to the spectral database B11, the color pattern of the camouflage visible-near infrared region is determined.

Accordingly, the present invention stores the digital image and color of each constituent pattern completed from the method for calculating the staining pattern for each pattern of the camouflage pattern that satisfies the camouflage conditions of the visible-near infrared region as an image file, and the digital image of the stored constituent pattern It provides a camouflage fabric that meets the camouflage conditions in the visible-near-infrared region, which consists of printing colors on the fabric.

According to the present invention, the pattern-specific dyeing method of the camouflage pattern satisfying the camouflage conditions of the visible-near infrared region provides an optimal camouflage pattern that can simultaneously satisfy the camouflage conditions of the visible region of daytime and the near-infrared region of night at a given natural environment. To be configured.

In addition, the present invention can easily obtain the prescription of the necessary dye for each pattern necessary to implement the optimum camouflage pattern to the fabric to satisfy the gastrointestinal conditions of daytime visible region and night-infrared region at the same time in the given natural environment. do.

Accordingly, the present invention can provide a fabric having a camouflage pattern that is the same as the pattern of the natural environment by printing on the fabric by using the pattern of the pattern of the camouflage pattern, the digital image for each color and the prescription of the necessary dye for each pattern.

Specifically, the present invention is to secure the digital image from the natural environment (S11);

Determining a camouflage visible region digital pattern from the digital image (S12);

The pattern-specific spectrum of the visible-near-infrared region of the camouflage pattern to be obtained by replacing the camouflage visible-area digital pattern determined in the step S12 with the spectral database B11 of the visible-near-infrared region of the natural product. Determination step (S13); And

Step S14; It provides a method for calculating the dyeing pattern for each pattern of the camouflage pattern to satisfy the camouflage conditions of the visible-near infrared region.

1 is a flowchart illustrating a method for calculating dyeing prescription for each pattern of a camouflage pattern satisfying the camouflage conditions of the visible-near infrared region of the present invention.

Hereinafter, the present invention will be described in detail step by step.

1. Digital image acquisition step from the natural environment (S11)

The image used in the present invention includes all photographs taken of the natural environment, color copies scanned from the photographs, photographs of the natural environment, or all images digitized by scanning them.

In this step (S11), the colors for each of the constituent patterns of the natural environment image are selected to represent various constituent colors of the natural environment as several representative colors, and the color characteristic values of the area ratio corresponding colors in the entire image with respect to the pattern L *, a *, b *) is calculated to reconstruct the natural environment image into several representative colors.

2. Determination step of the camouflage visible area digital pattern in the digital image (S12)

From the digital image of the natural environment secured in the step S11, the color pattern in the visible region constituting the image is subdivided, wherein the area ratio of the subdivided color pattern and color characteristic values (L *, a *, b *) Based on the above, a plurality of colors having a large composition ratio are selected to reconstruct an image.

This will ensure that the camouflage pattern has a pattern that is closest to the given natural environment in several representative colors.

Thus, in the step S12, the area ratio in the entire image of the pattern calculated in the step S11 among the patterns selected in the step S11 in order to represent the various constituent patterns of the natural environment as several representative patterns. The number of representative patterns and their colors are determined by considering the color characteristic values (L *, a *, b *) and the number of colors (printing frequency) to be displayed in the final camouflage welfare.

3. Spectrum-determining step for each pattern in the visible-near-infrared region of the camouflage pattern (S13)

In this step S13, the camouflage visible region digital pattern determined in the step S12 is replaced with the spectral database B11 of the visible-near-infrared region of the natural product, which has been constructed in advance, to obtain the visible pattern of the camouflage pattern to be obtained. As a spectrum-determining step for each pattern of the near infrared region, first, the construction of the spectral database B11 of the visible- near infrared region of natural products will be described.

FIG. 2 shows an example of a spectral database B11 of the visible-near-infrared region of natural products, and shows visible-near-infrared spectral characteristic values of natural objects (leaves, tree skin, soil, rocks, etc.) existing in a given natural environment. Build a database by securing the reflectance).

More specifically, even if the digital image of the natural environment secured in the step S11 is the same natural object, the color or tone varies depending on the location or the photographing environment. In addition, since the image obtained in step S11 contains only visible light range information, the obtained image data should be replaced with the average information of actual natural constituents to obtain objective pattern characteristics of the natural environment including both visible and near infrared regions. have.

Accordingly, this step (S13) is for a wide range of natural objects, the spectrum in the visible region and the near infrared region (350nm ~ 1200nm) is measured by a visible-near infrared spectroscopy (spectrophotometer) to build the spectral information of the natural object. In addition, spectral information of known natural products can be used as they are if the wavelength ranges match.

By establishing a spectral database of the natural-visible-near-infrared region, if spectrum values are obtained in a plurality of different environments with respect to one natural product, even if the same natural product is used, the spectrum varies depending on the image acquisition environment, surrounding conditions, observation angles, and the like. On the contrary, a pattern capable of better camouflage can be obtained.

The digital image of the natural environment secured in step S11 is reconstructed into several patterns (including shapes and colors) as in step S12, and the color of the reconstructed pattern is constructed by step S13. By replacing the spectral database B11 in the visible-near-infrared region of the natural product, the spectrum of the visible region of the color for each pattern constituting the digital image can be set, and the digital image of the natural environment secured in the step S11 can be set. The spectrum of the near infrared region which is not included can be secured.

By the above method of extracting a camouflage pattern, the present invention can establish a method capable of objectively inducing an optimal camouflage pattern according to a given surrounding environment.

4. Obtaining a prescription combination required to print on the fabric by color matching (S14)

In order to be camouflaged even under a near-infrared telescope, the spectrum in the near-infrared region of the pattern constituted by the combination of dyes used to match the color of the visible region above must be equal to that of the natural environment of the target pattern. Therefore, the dye used to obtain a prescription for each color of the gastrointestinal pattern should include not only the visible region but also the spectral data of the near infrared region.

Thus, the step of constructing the database B12 of the dye in which the spectral characteristic information of the visible-near-infrared region is stored will be described.

FIG. 3 shows an example of a database B12 of a dye in which spectral characteristic information of visible-near-infrared regions is stored for calculating a pattern-specific dyeing prescription of a camouflage pattern of the present invention. First, a dye selected from a plurality of dye groups The dyeing prescription of the dye required to implement the pattern of the camouflage visible-near infrared region determined in the step (S13) to the fabric should be the same as in Equation 1 below. That is, the density | concentration of the dye group which satisfy | fills Formula (1) is calculated | required.

Equation 1

f (R) = f (Rw) + (A ₁ × C ₁ ^g1 ) + (A ₂ × C ₂ ^g2 ) + (A ₃ × C ₃ ^g3 ) +. ... + (A _n × C _n ^gn )

In Equation 1, R is a reflectance for each wavelength of a target color, Rw is a reflectance of the fabric itself to be printed, f (R) is a spectral vector of the target color, and f (Rw) is a spectral vector of the fabric. Where A is a spectral vector for the unit concentration of each dye, C is a concentration vector of n dyes satisfying the target color, and g is a nonlinear factor between the spectral vector f (R) and the concentration vector C of the color.

At this time, the relationship between the reflectance R and f (R) may be given in various forms, the most common relationship is by the function of Kubelka-Munk or a modification thereof as shown in Equation 2 below.

Equation 2

f (R) = (1-R) / (2 × R)

Similarly, the relation of the reflectance of the fabric itself is satisfied.

Using Equation 3 in which Equation 1 is modified again, the number of dyes (n) required to make a target color and the concentrations C ₁ , C ₂ ,... ... C _n can be found.

Equation 3

f (R) -f (Rw) = (A ₁ × C ₁ ^g1 ) + (A ₂ × C ₂ ^g2 ) + (A ₃ × C ₃ ^g3 ) +... ... + (A _n × C _n ^gn )

In the manufacturing method of the present invention, in the step (S14), the CIE in the visible region between the spectrum obtained by the dye prescription selected from the plurality of dye groups and the spectrum for each pattern of the visible visible near-infrared region determined in the step (S13) The color difference ΔE in the L * a * b * system is as in Equation 4 .

Equation 4

ΔE = (ΔL ² + ΔC ² ) ^1/2

(Wherein ΔL is the difference in brightness between the two spectra, ΔC is the difference in saturation between the two spectra, and saturation C in the a *-b * chromaticity coordinates is C = (a * ² + b * ² ) ^1/2 .)

In addition, the difference between the two spectra in the near-infrared region is defined as the difference in the brightness (ΔLir) when viewed with a night vision device, as shown in Equation 5 .

Equation 5

Lir = 200 (Yi) ^1/3 -16

ㆍf(Ri)이며, Yir(i)는 야시장비의 700～1200nm 범위에서 파장별 감도, f(Ri)는 Kubelka Munk 함수, k는 정규화 인자로 k =

F (Ri), Yir (i) is the sensitivity for each wavelength in the range of 700 ~ 1200nm of the field of vision equipment, f (Ri) is the Kubelka Munk function, k is the normalization factor, and k =

to be.

In step (S14) of the manufacturing method of the present invention, a combination of prescription values for each pattern is given in plurality, and the selection of the optimal dyeing prescription is selected from a plurality of groups in consideration of characteristics of dyes such as ΔE, ΔLir and dye price, color fastness, etc. Can be.

Furthermore, the present invention stores the digital image and color of each constituent pattern completed from the dyeing prescription for each pattern of the camouflage pattern as an image file, and prints the digital image and color of the stored constituent pattern on the fabric, visible in a given environmental conditions Provides a camouflage fabric that optimally meets the camouflage conditions in the near infrared region.

As shown in (B11), the target for each pattern of the camouflage visible-near infrared region determined in step S13 for each pattern using the database B12 of the dye in which the spectral characteristic value information of the visible-near-infrared region previously constructed is stored. The dyeing prescription of the dye (the type and concentration of the dye satisfying the above conditions) necessary for embodying the color on the fabric is obtained using a color matching technique.

In general, the principle and method of color matching are the method of maximally matching the color characteristic values (for example, tristimulus values X, Y, Z) of the left and right sides (metameric matching method) or the spectrum of the left and right sides in Equation 3 The optimum combination of dyes (number and type of dyes and respective concentrations) is calculated by isomeric matching.

Figure 4 shows a screen that is monitored through a computer program the performance of the method of selecting a staining prescription for each pattern of the camouflage pattern to meet the camouflage conditions of the visible- near infrared region of the present invention.

In the present invention, both of the above methods can be used for prescription calculation, and the number of dyes used for prescription calculation is not limited, but considering that the number of dyes actually used for each color pattern is about 3 to 4, It is advantageous in many ways to choose a dye group that is made up of compatible dyes.

In this case, the number of dyes included in the prescription for one color implementation may be prescribed in plural numbers according to the calculated color range of the prescription, and the number of prescriptions may be presented in two or more.

In addition, if it is determined that the prescription of some colors obtained is inappropriate, it is possible to calculate the prescription by a combination of various dyes by changing the type and number of dyes to mobilize the prescription calculation.

At this time, the plurality of dyes of the pattern-specific spectral characteristic value of the spectral database (B11) of the visible-near-infrared region of the natural product constructed in the step (S13) and the camouflage visible-near-infrared region determined in the step (S14) The color difference between the spectra for each pattern is preferably minimized, and more preferably set within a color difference range of less than 1.5, which is difficult for a human to distinguish.

Further, the brightness difference ΔLir in the near infrared region between the two spectra is set to be within 10. At this time, as the ΔLir becomes larger or smaller than 10, there is a possibility that it becomes difficult to camouflage the night vision equipment.

From the above method, the same camouflage pattern as that of the given natural environment can be easily obtained, and the obtained pattern can be dyed to a given fiber fabric, and the same reflectance as the natural environment for the visible-near-infrared region (350-1200 nm) at the same time It is possible to formulate dyes for the implementation of a camouflage pattern to have properties.

Furthermore, when the prescription calculation for each pattern of the camouflage pattern is completed, as shown in FIG . 5 , the pattern and color of the obtained constituent pattern are stored in a picture file, and the pattern is printed in the print CAD using the stored picture file. It is confirmed and printed on the fabric to provide a camouflage fabric that meets the camouflage conditions in the visible-near infrared region.

Hereinafter, the present invention will be described in more detail with reference to Examples.

This example is for explaining the present invention more specifically, and the range of fibers and dyes used in the present invention is not limited to these examples.

≪ Example 1 >

As shown in FIG. 4, the performance of the present embodiment will be described with reference to the execution screen of the computer program. First, the photograph 4- (a) taken in the forest was secured, and the main constituent patterns of 4- (a) were analyzed. The expected main components are as shown in 4- (b). Among the colors of the pattern shown in 4- (b), the main constituent pattern representing the image of 4- (a) is the main constituent ratio in consideration of the area ratio and color characteristic values for each quantified color pattern of 4- (b). Five visible colors were selected and confirmed as 4- (c) by the camouflage visible area digital pattern.

Subsequently, the five color patterns of 4- (c) are replaced with the natural products represented in 4- (a) on the spectral database B11 of the visible-near-infrared region of the pre-built natural product as shown in FIG. [4- (d)].

In this case, the spectrum of the natural product is difficult to obtain at various intensities (brightness), so if one is obtained and set, a representative one is adjusted to the brightness most similar to the selected color when the selected color pattern is replaced with the natural object constructed in (B11). Make up the video.

In the 4- (d), the digital pattern of the visible region selected as the representative pattern of the 4- (a) image is replaced with the natural one, so that the representative patterns of the 4- (a) image are replaced with all the spectral information of the visible-near infrared region. Accordingly, the representative pattern of the 4- (a) image can be identified not only in the visible region as in 4- (d) but also in the near-infrared region observed by the night vision equipment.

In order to implement the pattern-specific spectra of the camouflage visible-near-infrared region determined as the representative pattern of the 4- (a) image as described above, the dyeing prescription for each pattern required for printing with a dye dye for cotton fibers is shown in FIG. It calculated as in step S14.

At this time, the number of dyes used in formula calculation was selected to seven listed in Table 1 and Table 2.

In Table 1, as the dyes selected from Table 2, the staining prescriptions for the five colors for implementing the 4- (d) image were calculated.

In Table 1, two possible prescription combinations are set for one color, but it can be composed of multiple prescription combinations according to the number of dyes and the color range of the prescription. In addition, if it is determined that the prescription of some colors obtained is inappropriate, various dye prescription calculations are induced by changing the type or number of dyes that can be mobilized for prescription calculation.

4- (e) in FIG. 4 shows images in the visible region and near-infrared visual field of the gastrointestinal pattern implemented in the cotton fiber by the calculated prescription.

In this case, the smaller the color difference (DE) of each pattern of the image 4- (e) and 4- (d) image implemented on the cotton fabric with the dyeing prescription calculated as shown in Table 1, the more preferably, it was set to 1.5 or less. In addition, in the near-infrared region, the brightness (DLir) in the night vision equipment is less, the better the night camouflage performance, it is preferable to be less than 10.

In Example 1, the color difference DE was less than 1.5 and the DLir was less than or equal to 10 in all patterns.

<Example 2>

The digital image and the color of each component pattern completed in Example 1 are shown as shown in (1), (2), (3), (4) and (5) of FIG. Specifically, given a camouflage visible region digital pattern spectrum determined from a digital image, the (R, G, B) value is obtained from the spectrum and represented on the monitor as a visible image.

The digital image and color of the stored structural pattern were printed on cotton fabric using the prescription obtained in Example 1. At this time, the pattern and color of the constituent pattern for which the prescription calculation is completed are stored as the picture files of (1), (2), (3), (4) and (5), as shown in FIG. Using to determine the pattern in the printing CAD to produce a camouflage fabric through the printing operation on the fabric.

As described above, the present invention extracts the image and color of the camouflage pattern to satisfy the camouflage conditions of the visible region of the day and near-infrared region of the night for a given natural environment, and the camouflage pattern is printed on the fabric To provide a method for calculating the dyeing prescription for each pattern to implement.

That is, the present invention constructs spectral information over a wide range of visible and near-infrared regions of natural objects (B11), and replaces the digital image obtained from the natural environment with the pattern color of the visible region of the natural environment, thereby disguising the visible- The spectrum for each color pattern of the near infrared region can be obtained.

Furthermore, the present invention is a fabric of the pattern-specific spectrum of the visible-near-infrared region for the camouflage in the pattern-specific spectrum of the visible-near-infrared region for the camouflage in the database (B12) of a plurality of dyes stored spectral characteristic information of the visible-near-infrared region The dyeing prescription required for printing may be calculated through color matching technique, and the dyeing prescription may be printed onto the fabric to provide a camouflage fabric that is optimal for a given natural environment in the visible region and the near infrared region.
