The invention provides a test paper reading method and a test paper reading device, which can read dry chemical test paper strips, colloidal gold immunochromatograohic assay test paper strips / cards and rapid pesticide residue test cards, are easy to operate, need no extra detection instrument and equipment, can automatically judge and read the detection result by only acquiring corresponding developing pictures through electronic equipment such as computers or mobile phones, have reliable testing accuracy and are particularly suitable for personal and household wide application. The method comprises the following steps: A. acquiring images; B. processing the acquired images; C. performing negative and positive discrimination; and D. performing concentration conversion on a sample which is discriminated to be positive in the step C through a concentration-gray scale relation to obtain a concentration value of the to-be-tested paper card / strip. The device comprises a shell and a built-in standard gray scale strip, wherein the shell is provided with a standard gray scale strip display window and is also provided with a first card slot, a second card slot and a third card slot for arranging the colloidal gold card, the rapid pesticide residue test card and the dry chemical test paper respectively.
Description
technical field [0001] The invention relates to a test paper reading method and device, which are used for reading dry chemical test paper strips, colloidal gold immunochromatographic test paper strips or test paper cards, and pesticide residue rapid test cards for enzyme inhibition methods. Background technique [0002] As a rapid on-site detection method, the test paper method is characterized by simple operation, convenient portability, low price, and certain selectivity, accuracy and sensitivity. The test paper method includes dry chemical test paper, biological test paper, etc. Due to its characteristics of easy portability, simple operation, and fast measurement speed, it has attracted more and more attention from people, and it has played an increasingly important role in rapid on-site detection. Dry chemical test paper, pesticide residue test paper, colloidal gold test paper, etc. have been widely used in food, water quality, air, medical and health and other fields....
