Example Embodiment
[0035] Example 1: Refer to the attached Figure 1-11 . A CCD type colloidal gold immunochromatographic diagnostic test paper quantitative analysis system, which is composed of an image collector, a data processor, and a result output; the signal exchange end of the main board in the data processor is respectively connected with the image processing and reading software and the image collector The industrial camera in the two-way data exchange. The image collector is composed of a target tray, an LED lighting room, an optical plane mirror, and an industrial camera. The receiving surface and the reflecting surface of the optical plane mirror are distributed at 45 degrees and the LED lighting room located below the optical plane mirror illuminates the measured target The above light is reflected vertically to the 45-degree distributed optical plane reflecting mirror, and the measured target image is reflected to the industrial camera lens through the 45-degree distributed optical ...
Example Embodiment
[0066] Example 2: On the basis of Example 1, a CCD type colloidal gold immunochromatographic diagnostic test paper quantitative analysis method, the light is emitted from the LED lighting chamber, irradiated on the test strip after the reaction, and the surface of the test strip is diffused. After reflection, the light is reflected by the optical plane mirror to the industrial camera, and the digital image is taken by the industrial camera, and then sent to the computer software for analysis and processing, and finally the reading values of the test line and the quality control line on the colloidal gold immunochromatographic diagnostic test paper are obtained. On the test strip test line and quality control line, due to the light absorption characteristics of gold nanoparticles, the scattered light signal at the test line-T line and quality control line-C line will be less than that of other areas of the test strip Signal, after the brightness analysis of the real-time image,...
