Problems solved by technology

[0003] Since the test results of the current immunochromatographic test strips mainly rely on the naked eye to judge the results, the test results of the immunochromatographic test strips can generally only be used for qualitative judgment results. Shallow, it is often difficult to judge the results with the naked eye at this time, and it is easy to cause misjudgment. Moreover, the original color rendering results cannot be kept for archiving after each test, especially the public security departments and commodity inspection departments need to keep the original results, so the practicability is limited. very restrictive

[0004] At present, there are also some devices used for quantitative detection, but they are all realized by the principle of photoelectric sensors. Due to the sensitivity and method of this principle itself, the purpose of quantitative detection in the true sense cannot be achieved. There are several disadvantages as follows:

The grayscale / chromaticity limit resolution of the human naked eye is about 4 to 5 levels of difference, and the image information below this limit cannot be distinguished by human eyesight.

When the concentration of the detected object is very low, the resolution is about 4 levels, and when it is almost close to the critical value, the color of the color band or color block in the test color area is very light, and it is difficult for the human eye to distinguish the tomographic test. Whether there is color on the board, it is easy to make a judgment error

[0006] At present, all devices made by using the principle of light reflection to detect the detection results of immunochromatography test plates, due to the limited sensitivity of the light receiving sensor itself, coupled with the noise of components, when the concentration of the detected object is very low, When it is almost close to the critical value, when the color of the color band or color block in the test color area is very light, this type of instrument cannot distinguish whether there is color, and it is prone to wrong judgment results

[0007] However, no matter whether the detection results of the immunochromatographic test plate are directly judged by the naked eye, or the detection results are judged by means of a device made of a photoelectric sensor, there is a problem of limited resolution of gray scale / chromaticity, and it is easy to be caused by individual differences of the testers. Or the sensitivity of the device, to draw wrong conclusions

[0008] Disadvantages of the prior art: most of them use devices made of artificial naked eyes or photoelectric sensors to discriminate the detection results of immunochromatographic test plates. The accuracy and stability of the discrimination are poor, quantitative analysis cannot be performed, and the original data cannot be preserved. Image data
