Problems solved by technology

[0002] In the prior art, when designing a waterjet pattern, the designer usually uses drawing software to manually color match the material of the area in the drawn pattern, but the pattern is often complicated, and the color matching process is very cumbersome and takes a lot of time
In addition, some designers are inexperienced, which will also cause the problem of unsatisfactory color matching effects.

Embodiment 1

[0045] refer to figure 1 The flow chart of a color matching method shown can be executed by electronic devices such as computers and processors, and the method mainly includes steps S101 to S106:

[0046] Step S101, import the color matching file into the preset software to generate wireframe diagram and point, line and surface data.

[0047]Wherein, in this embodiment, the file to be matched includes a file generated from an image drawn by CAD software, and the preset software is a pre-designed color matching software. Save the CAD file in DWG format or DXF format, then import the CAD file into the preset software for analysis, and output the blank black and white wireframe after analysis, with a size of 512*512. If it is a rectangle or a special-shaped pattern, the longest The edge is scaled to 512, and then the shortest edge is evenly filled to 512, and the analyzed point, line, and surface data, as well as the contour point data of all polygons in the graph are output at ...

Embodiment 2

[0065] refer to image 3 A schematic diagram of a color matching device shown, including:

[0066] The import unit 301 is used for importing the file to be matched into preset software to generate a wireframe diagram and point-line-surface data.

[0067] The color matching unit 302 is configured to color match the wireframe image according to the pre-trained GAN model to generate an RGB image.

[0068] The segmentation unit 303 is configured to segment the RGB image according to the point-line-plane data to obtain multiple closed areas.

[0069] The analysis unit 304 is configured to analyze multiple closed areas by principal component analysis to obtain RGB pixel values ​​of each closed area.

[0070] The matching unit 305 is configured to use the Euclidean distance method to match the RGB pixel value of each closed area with the preset color material type to obtain the corresponding color of each closed area.

[0071] The generating unit 306 is configured to match the sam...

Abstract

The invention provides a color matching method and device, and electronic equipment, and relates to the technical field of image color matching, and the method comprises the steps of importing a to-be-color-matched file into preset software to generate a wireframe diagram and point-line-surface data; performing color matching on the wireframe diagram according to a pre-trained GAN model to generate an RGB image; performing region segmentation on the RGB image according to the point-line-surface data to obtain a plurality of closed regions; analyzing the plurality of closed regions by using a principal component analysis method to obtain an RGB pixel value of each closed region; matching the RGB pixel value of each closed region with a preset color material type by using an Euclidean distance method to obtain a corresponding color of each closed region; and performing color matching on the same closed areas in the plurality of closed areas according to the corresponding colors to generate an effect picture of the file to be subjected to color matching. The color matching operation can be effectively simplified, the working efficiency is improved, and the color matching rationality is improved.

Description

technical field [0001] The invention relates to the technical field of image color matching, in particular to a color matching method, device and electronic equipment. Background technique [0002] In the prior art, when designing waterjet patterns, designers usually use drawing software to manually color match materials for the areas in the drawn pattern, but the patterns are often complex, and the color matching process is very cumbersome and takes a lot of time. In addition, some designers are inexperienced, which will also cause the problem of unsatisfactory color matching effects. Contents of the invention [0003] The purpose of the present invention is to provide a color matching method, device and electronic equipment, which can effectively simplify the color matching operation, improve work efficiency and improve the rationality of color matching. [0004] In a first aspect, the present invention provides a color matching method, including: [0005] Import the c...
