However, due to various reasons, various test papers are still not available to thousands of households.
The main reason is that many current applications either use complex electronic equipment to analyze the change of the color of the test paper, which is a high-cost and long-term test solution, or directly use human eyes to interpret it. Misjudgments or large deviations in results

Embodiment 1
[0065] refer to figure 1 A method for analyzing biological test paper using mobile phone imaging, comprising the following steps:
[0066] S1: Use the camera of the mobile phone to obtain the sampling frame image on the test strip, white balance the sampling frame image and then perform grayscale processing to obtain the grayscale image of the sampling frame, and obtain the array A(m) in the grayscale image of the sampling frame ,n).
[0067] Among them, after the test strip is sampled for a certain reagent, it will present a test line and a quality control line, that is, T line and C line. The function of the sampling frame is to frame the color-developing part on the test strip, that is, to frame the T line and the C line, so that the T line and the C line are located in the relative middle of the sampling frame. And in the sampling frame, the T line is on the left, and the C line is on the right. The array A(m,n) is obtained from the grayscale image of the sampling frame...
Embodiment 2
[0106] Embodiment 2 also discloses a method for analyzing biological test paper using mobile phone imaging. Compared with the method in Embodiment 1, the difference between this method is that step S1 is different, and a step is added between steps S6 and S7. For the convenience of description, step S7 in Embodiment 1 is changed to step S8 in this embodiment, and the newly added step in this embodiment is S7.
[0107] S1: Use the mobile phone camera to obtain the total image on the test strip, the total image includes the sampling frame image, and then perform grayscale processing on the total image to obtain the total grayscale image, and obtain the total grayscale image Array Z(x,y), and array A(m,n) in the sampling frame image in the total grayscale image.
[0108] The reason why the total grayscale image is obtained is that if the sampling of the C-line area or T-line area in the sampling frame image is incomplete and the elements need to be expanded, the elements are obta...

Abstract
The invention discloses a method for analyzing biological test paper by using mobile phone imaging. The method includes the following steps that an array A (m, n) representing a sampling frame image is obtained; median filtering processing is performed on the array A (m, n) to obtain an array C (m, n); summation processing is performed on all columns of elements in the array C (m, n) to obtain an array Dn; difference processing is performed on the array Dn to obtain an array En; the array En is analyzed, and the sum value Csum of a C line area after a background is removed and the sum value Tsum of a T line area after a background is removed are solved; Tsum is divided by Csum, the obtained result is recorded as a K value, and the concentration represented by the K value is obtained according to the relation between the K value and a preset concentration corresponding value. The method has the advantages that a mobile phone can be used for shooting the image of the test paper on which reagent sampling is already carried out, and the concentration of a reagent which is sampled on the test paper can be read by analyzing the color specific value between the T line area and the C ling area.
Description
technical field [0001] The invention relates to the field of test paper analysis, in particular to the use of mobile phone imaging to analyze biological test paper to obtain the concentration of reagents on the test paper. Background technique [0002] Biological test paper is a common method to reflect a certain biological parameter through color depth. But due to various reasons, various test papers still cannot approach thousands of households. The main reason is that many current applications either use complex electronic equipment to analyze the change of the color of the test paper, which is a high-cost and long-term test solution, or directly use human eyes to interpret it. This may lead to problems such as misjudgment or large deviation of the results. After several years of development, smart phones have entered thousands of households, and almost everyone has one. Therefore, how to use the camera of the smart phone to take images of biological test strips, so as ...
