Problems solved by technology

[0004] At present, bionic color design lags behind the color extraction of rough and shallow surfaces, without more accurate color extraction and analysis, and there is relatively little academic research and practice on the application of bionic color design in home textiles, and relevant theoretical research needs to be done. further improvement

Embodiment 1

[0028] A design method for color extraction optimization in this embodiment includes the following steps:

[0029] a) Through proper sorting and screening, select the orange butterfly specimen as the color bionic object;

[0030] b) Extract the color parameters of the Nephila orange specimen, put the Nephila orange specimen into the VeriVide light box, and then extract the color of the Nephila orange specimen;

[0031] c) adopt the digital camera to take pictures of the orange powder butterfly specimens with color extraction, and obtain the specimen photos with RGB values;

[0032] d) Use the DigiEye color analysis system to correct the photos of the orange butterfly specimens with RGB values ​​to obtain the digital photos of the color standard;

[0033] e) After obtaining the digital photo of the color standard, use the DigiEye color analysis system to read the XYZ color value of the digital photo of the color standard, and then convert the XYZ color value into an L*a*b* col...

Embodiment 2

[0048] A design method for color extraction optimization in this embodiment includes the following steps:

[0049] a) Through proper sorting and screening, green agate is selected as the color bionic object;

[0050] b) Extract the color parameters of the green agate, put the green agate into the VeriVide light box, and then extract the color of the green agate;

[0051] c) adopting a digital camera to shoot the green agate with color extraction to obtain a sample photo with RGB values;

Abstract

The invention provides a design method for color extraction optimization, which is characterized in that it comprises the following steps: a) selecting a color bionic object; b) extracting natural color parameters; c) using a digital camera to photograph the specimen to obtain a photograph of the specimen with RGB values ; d) modify the photo of the specimen with RGB value to obtain the color standard digital photo; e) read the XYZ color value of the color standard digital photo, convert the XYZ color value into L*a*b* color value, and obtain the color of each color Percentage; f) convert the original data of the sample L*a*b* color value into Munsell color; g) correct the Munsell value obtained by comparing the image coordinates based on the PCCS color system, and obtain the corresponding hue; h) draw Aiming at the monochromatic image coordinates and color image coordinates of the biological color, quantitative analysis is carried out to obtain the color scheme. The design method for color extraction optimization of the invention provides new ideas and methods for the design of home textiles, and expands the means of design.

Description

【Technical field】 [0001] The invention relates to the technical field of digital image processing and color, in particular to a design method for color extraction optimization. 【Background technique】 [0002] Bionic color design belongs to the branch of form bionic in bionic design. Bionic design refers to a design concept and method that consciously seeks inspiration from the biological world in product design, or directly simulates the function, structure or form of organisms. Since "bionics" was first proposed at an academic conference in the United States in 1960, the objects of bionics have not only been limited to "living things", but also extended to "non-living things" in nature. In Xu Bochu's "Bionic Design" The book "Introduction" clearly points out that: Color bionics is a method of simulating natural organisms and environmental colors and applying them to product color design. [0003] The main purpose of studying natural colors is to try to find those exciting...
