Abstract

The invention discloses a computer-assisted same-color same-spectrum paint color matching method, and belongs to the technical field of camouflage color camouflage design. The method comprises the following steps: establishing a basic pigment data establishing spectral data of various pigments at different concentrations; establishing a two-parameter calculation model: establishing an optical model based on an absorption coefficient and a scattering coefficient; establishing a full-spectrum color matching model: in a full-wavelength range, fitting a spectrum curve to be consistent with a target spectrum curve; and solving by adopting a dual simple line method: fitting an optimal spectrum curve and a pigment proportion thereof by adopting the dual simple line method. The technical means of simulating color matching through a computer is adopted, and the effect that the matched color and the background color are the same in color and spectrum is achieved.

Description

technical field

[0001] The invention discloses a computer-aided color matching method for same-color and same-spectrum paint, which belongs to the technical field of camouflage and camouflage design.

[0002] technical background

[0003] Camouflage camouflage mainly refers to the coating of camouflage paint or other materials on the surface of the equipment to change the spectral characteristics of the equipment surface to reduce the salience of the target or to distort and segment the outline of the target. Photography and multispectral imaging for reconnaissance and guided attack, etc. The principle of camouflage design is to make the color and brightness of some spots blend with the background and become a part of the background.

[0004] At present, most camouflage paints can only achieve the same color in the visible light band as the background color. However, the new generation of camouflage paint must meet the requirements of the consistency of the reflection spect...

Examples

Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0053] A computer-aided color matching method for paints with the same color and spectrum, comprising the steps of:

[0054] (1) Establishment of basic pigment database

[0055] Mix the base color paste with other pigment color pastes in different proportions to obtain several mixed color samples with different concentrations, and measure the optical parameters and spectral data of these mixed color samples as the basic data of the pigment in the basic pigment database;

[0056] The basic database establishment steps are as follows:

[0057] (1) Color sample configuration;

[0058] (2) Measure the reflectance spectrum r of each group of mixed color samples with a UV-visible spectrophotometer i , where r represents the reflectance spectrum, i represents the type of pigment, and r i Represents the reflectance spectra of different pigments;

[0059] (3) Est...
