HSV/HSB color space colorimetric method and system for determining concentration of monochromatic solution and storage medium

Abstract

The invention provides an HSV / HSB color space colorimetric method for measuring the concentration of a monochromatic solution. The HSV / HSB color space colorimetric method comprises the following steps of acquiring a monochromatic color image of a to-be-measured solution acquired by an image acquisition device under the irradiation of a light source, obtaining the brightness value and saturation value of each pixel point of the color image under an HSV / HSB model, obtaining a corresponding brightness mean value and a saturation mean value according to the brightness value and the saturation value of each pixel point, and indicating a color depth representation value according to the ratio of the brightness mean value to the saturation mean value so as to match the concentration tau of the to-be-detected solution. A relationship is built between the color depth characterization value of the color image of the to-be-detected solution and the concentration of the to-be-detected solution, and the concentration of the to-be-detected solution can be solved by obtaining the brightness value and the saturation value of the color image of the to-be-detected solution. The method can be used for measuring the concentration of a single to-be-measured solution and measuring the concentrations of a plurality of to-be-measured solutions at the same time, high-throughput quantitative analysis is realized, and the operation is simple and rapid.

Description

technical field

[0001] The invention relates to the technical field of detection, in particular to an HSV / HSB color space colorimetric method, system and storage medium for measuring the concentration of a single-color solution. Background technique

[0002] The colorimetric analysis method is to use the color of the tested colored solution itself, or the color presented after adding the reagent, to observe and compare the color depth of the colored solution with the eyes (or a visual colorimeter), or to measure with a photoelectric colorimeter to determine the color. A method for measuring the concentration of a substance in a solution. At present, the commonly used method is generally to use the principle of spectrophotometer for colorimetric analysis. By setting up laser transmitters and receivers on both sides of the container holding the sample to be tested, by measuring the light absorption of the colored solution at a specific wavelength or within a certain wavelength...

Embodiment 1

[0042] Light is a kind of electromagnetic wave. The mixed light composed of electromagnetic waves of different wavelengths (380-780nm) in a certain proportion can be decomposed into continuous visible lights of various colors such as red, orange, yellow, green, blue, blue, and purple through a prism. spectrum. When white light passes through a solution, if the solution does not absorb all wavelengths of light, the solution has no color. If the solution absorbs some of the wavelengths of light, the solution takes on the color of the rest of the light that has passed through the solution. The color of the colored solution is the complementary color of the absorbed light. The more absorbed, the darker the complementary color. Comparing the depth of the color of the colored solution is essentially comparing the degree of absorption of the light absorbed by the colored solution.
