Problems solved by technology

[0007] The technical problem to be solved by the present invention is: in the existing test paper detection method, the accuracy and stability of manual judgment are poor, and quantitative judgment cannot be carried out, while machine judgment requires professional equipment, and may also need to rely on the experience judgment of professionals. Testing done in a professional place
The performance of traditional detection products will also decay with time, which will affect the measurement accuracy

Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0050] as attached figure 1 As shown, the system of the present invention includes a test strip 1, a mobile terminal 2, a cloud server 3 and a user 4. The camera 301 of the mobile terminal 2 first collects the identification code of the test paper 1 (step 101), and sends the identification code to the cloud server 3 (step 102), and the cloud server 3 calls information such as test paper detection items and batches from the database and returns to the mobile terminal. terminal (step 103), the mobile terminal 2 collects the picture of the color zone of the test paper (step 104), and sends the picture of the color zone to the cloud server 3 (step 105), and the cloud server calculates the concentration of the sample according...

Abstract

The invention discloses a test paper reading and analyzing method and system based on a mobile terminal camera, which is used for calculating a concentration value of a to-be-detected substance in a detection sample and analyzing a test result. The method comprises the following steps: collecting, by the mobile terminal camera, a test paper image, analyzing and identifying the edge of a color developing area, and intercepting a required color development area; calculating a color value or a gray value of a test area (T line) and a control area (C line) in the color development area picture, and calculating the concentration ratio of the sample by utilizing the ratio of the color value or the gray value of the test area (T line) and the control area (C line); calibrating the sample concentration ratio in batches, substituting the sample concentration ratio into a standard curve of the test paper of the batch to perform the fitting operation, and calculating the real concentration value of the to-be-detected substance in the sample; looking for a matched detection result according to the real concentration value, and transmitting the detection result to the mobile terminal.

Description

technical field [0001] The invention belongs to the field of test paper reading and analysis, in particular to a test paper reading and analysis method and system based on a mobile terminal camera and a cloud server. Background technique [0002] Test strips have been widely used in sample testing in many fields, such as routine urine testing, prenatal and postnatal care, and infertility testing commonly used in clinical medicine, formaldehyde and benzene content testing in environmental testing, and food safety testing. Clenbuterol, melamine, waste oil or pesticide residue detection, etc., need to use the corresponding special test paper for detection. [0003] Some simple test paper tests can be achieved by visually observing the test paper, such as early pregnancy test paper, but this method of visual test paper can only be used for qualitative detection, and if the content of the detected object is low and the color is light , It is prone to misreading, and the naked ey...
