Substance content detection method, system and device based oncolordata analysis

Abstract

The invention belongs to the field of content detection of color-changed substances, and specifically relates to a substance content detection method, system and devicebased on color data analysis. According to the technical scheme, the method mainly comprises the following steps: S1, creating a standard sample color database; S2, selecting color data corresponding to a certain amount of standard samples according to a detection result accuracy demand, and printing a plurality of color blocks; S3, shooting and frame the to-be-detected samples and the plurality of color blocks in onesame horizontal plane; S4, recognizing the color blocks inthe color the most close to the color data of the to-be-detected samples; and S5, finding out the substance content corresponding to the color blocks from the standard sample color database, and then defining to be the substance content in theto-be-detected sample. With the adoption of the method, the problems that a colourimetric card is used for visually comparing the color in case of little color difference, subjective factors highly influence the result, and the visual color difference comparing capability is limited, can be solved; the detection process is objective; the detecting accuracy is high; the field detection is convenient; the detection cost is low; and the result is accurate and clear.

Description

technical field [0001] The invention belongs to the field of substance content detection that produces color changes, and in particular relates to a substance content detection method, system and device based on color data analysis. Background technique [0002] For the detection of colored substances in liquid samples, a spectrophotometer test instrument can be used. For example, in the detection method of formaldehyde concentration, the national standard adopts adding formaldehyde to phenol reagent and then carrying out color reaction, and then detects the absorbance of colored substances in the solution through a spectrophotometer, and obtains the content of colored substances according to the absorption spectrum curve, thereby calculating the formaldehyde concentration. However, this method requires a specific spectrophotometric device, and there are problems such as complicated operation and calculation process, high dependence on the instrument during the use process, ...

Problems solved by technology

However, the system required by this method requires a special image acquisition device, including the structural cooperation of the image acquisition chamber and the optical channel, to complete the entire detection process, which still has a high dependence on external equipment, and the final color value of the sample to be tested The acquisition is still taken by the camera of the mobile phone and the color data is detected by selecting the center size part of the image. Different mobile phone camera structures and materials may cause deviations between the acquired image and the real image, and the deviation between the collected color data and the real data will be Lead to large deviations in the final concentration analysis results
