Patent 201110389165.9 proposes a method for searching the color-developed area of chromatography test strips through image processing technology. In this method, the computer is used to frame the color-developed area on the image first, and then search for the upper and lower boundaries, detection lines and quality control lines respectively. This method does not involve the concentration detection algorithm and the elimination of ambient light interference

Embodiment Construction
[0025] The invention provides a quantitative detection device and method for immunochromatographic test strips. By photographing a colorimetric card and an immunochromatographic test strip placed on the colorimetric card, photographed pictures are obtained, and then the photographed pictures are analyzed and processed to obtain the Measured substance concentration. Wherein, the immunochromatography test strip quantitative detection device may be a smart phone, the image capturing unit is a camera of the smart phone, and the analysis processing unit is an analysis processing software built in the smart phone. The device and the method of the invention can conveniently and quickly carry out quantitative detection of the concentration of the object to be tested, and eliminate the interference of ambient light, so that the detection result is more accurate.
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present inventi...

The present invention discloses an immunochromatography test strip quantitative detection apparatus and an immunochromatography test strip quantitative detection method. The method comprises: shooting colourimetric card and immunochromatography test strip placed on the colourimetric card to obtain shot pictures, and carrying out analysis processing on the shot pictures to obtain the concentration of an object to be detected, wherein the immunochromatography test strip quantitative detection apparatus can be a smart phone, the image shooting unit is the camera of the smart phone, and the analysis processing unit is the analysis processing software built in the smart phone. With the apparatus and the method of the present invention, the concentration of the object to be detected can be conveniently and rapidly subjected to quantitative detection, the environment light interference is eliminated, and the detection result is accurate.
Description
technical field [0001] The invention belongs to the field of mobile medical detection, and in particular relates to an immunochromatographic test strip quantitative detection device and method, where the immunochromatographic test strip is used to detect the concentration of a test substance. Background technique [0002] Colloidal gold chromatography test strips apply immune technology, chromatography technology and colloidal gold chromogenic technology, and can detect disease markers contained in blood, urine, saliva and other body fluids. Low cost and other advantages, so the development is very fast. Since the emergence of this technology, amazing development has been achieved, and dozens of measurable items have been achieved, including antigens and antibodies of infectious diseases, myocardial markers, tumor markers, hormones and various proteins. [0003] At present, colloidal gold chromatography test strips mostly use visual inspection for qualitative judgment, whic...
