Secretion test paper image recognition method based on color correction mode

The invention relates to a secretion test paper image recognition method based on a color correction mode. A secretion test paper comprises three parts, namely a two-dimensional code, a standard color card and detection test paper. After the test paper is used for sampling detection, a mobile phone is used for photographing, a test paper image is automatically collected and uploaded to a cloud platform, the cloud platform integrates an image recognition method, and a result is returned to the mobile phone after processing. The recognition method comprises the following steps: firstly, obtaining a test paper image, and then carrying out Harris corner detection to calibrate the image; generating a color correction model according to color data of a color correction color card in the image and standard color card data, performing brightness adjustment and color correction on the test paper image, performing accurate color restoration, and finally sampling the corrected test paper image to obtain a pixel value.
