  • METHOD AND DEVICE FOR DETECTING WATER QUALITY BASED ON COLOR RECOGNITION, AND STORAGE MEDIUM
    Publication number: 20210096121
    Abstract: A method and device for detecting water quality based on color recognition, and a storage medium. The method includes: collecting a water quality parameter sample and a RGB color parameter sample; normalizing the water quality parameter sample and the RGB color parameter sample; fitting a non-linear curve formed by RGB-PH values by using a RBF neural network model; establishing a RGB-water quality parameter lightweight database by using the non-linear curve of the RGB-water quality parameter; acquiring a color RGB value after a water sample to be detected reacts with a reagent; and comparing the color RGB value with the database to obtain a water quality detection parameter of the water sample to be detected.
