Problems solved by technology

However, when this determination method converts the test paper color patch image into a grayscale image, since the grayscale image only has brightness information, it will lead to the loss of effective color information on the one hand, and on the other hand, the image processing equipment may convert the grayscale image with higher brightness value into a grayscale image. Confusion between the high-degree image and the white background image makes the determined effective area inaccurate, which leads to the inability to determine the accurate effective color from the color block image of the test paper, which affects the detection of the concentration of urine components

Abstract

An embodiment of the present invention provides a method and device for determining effective colors in urine test paper, wherein the method includes: dividing the urine test paper image into multiple image areas centered on the initial sampling point; The average value of the color value of the pixel points within the range; for each adjacent pixel point of the initial sampling point, calculate the color difference value between the color value of the adjacent pixel point and the reference color value, and according to the size relationship between the color difference value and the preset threshold Judging whether to use the adjacent pixel as a new sampling point; when the adjacent pixel is determined to be a new sampling point, perform the step of determining the color difference value until all sampling points in the image area are determined; calculate multiple The mean value of the color value of the sampling point, and the color corresponding to the mean value of the color value is determined as a valid color. The embodiment of the present invention can improve the accuracy of the determined effective color, thereby improving the detection accuracy of the urine component concentration.

Description

technical field [0001] The invention relates to the technical field of urine test paper color analysis, in particular to a method and a device for determining effective colors in urine test paper. Background technique [0002] Urine test strips are a type of test paper used to test the concentration of different components in urine. The urine test paper is usually in the shape of a strip with a white background color, and multiple test paper color blocks are arranged in each urine test paper, and the multiple test paper color blocks are used to detect the concentration of different components in the urine. In the process of using software to analyze the component concentration of each test paper color block, it is necessary to collect the image of the urine test paper first, and then compare the color of each test paper color block image in the image with the standard color to determine the concentration of each component. [0003] Before comparing the color of the test pap...
