Abstract

The invention embodiment belongs to the technical field of communication and computer, and provides a method and a device used for calibration of light sources in test paper detection equipment. The method comprises following steps: test paper to be measured is inserted into a test paper detection equipment, and an actual measured image of the test paper to be measured is obtained; a first calibration image is obtained; the first calibration image and the actual measure image are subjected to processing so as to obtain relative gray values and / or relative channel color values of pixel points in a preset zone of the actual measured image; and the gray values and / or the channel color values of the corresponding pixel points on the calibration image of standard test paper and the corresponding pixel points on the actual measured image of the test paper to be measured are subjected to related treatment so as to obtain the real gray values and / or the channel color values of the test paper to be measured, eliminate measuring error of the test paper to be measured caused by light source illumination nonuniformity of the test paper detection equipment, and avoid inaccurate measuring results caused by the illumination nonuniformity of test paper in the prior art.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication and computer technology, and more specifically, embodiments of the present invention relate to a method and device for calibrating light sources in test paper detection equipment. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Gold-labeled immunochromatography is a solid-phase labeled immunochromatographic detection technology developed in the 1980s that uses colloidal gold as a marker. Because of its strong specificity, high sensitivity, simplicity and speed, it has been widely used in human medicine, agriculture and animal husbandry, food safety and environmental monitoring and other fields. In recent years, research on quantitative gold standard immunochromatography has ...
