The invention relates to a method and a device for adjusting the vibration intensity of an electric
toothbrush. The method comprises the following steps: acquiring a real-time
oral cavity image of a user, carrying out
anomaly detection on the real-time
oral cavity image, marking an abnormal area of the real-time
oral cavity image, extracting a reference oral cavity image and reference adjustment information corresponding to the abnormal area from a preset
database, carrying out feature comparison
processing on the real-time oral cavity image and the reference oral cavity image, and judging whether the real-time oral cavity image is abnormal or not. Judging the redness and swelling degree of the gum of the user, and adjusting the vibration intensity of the electric
toothbrush according to the redness and swelling degree of the gum and the reference adjustment information, so that the user can
clean teeth by adopting the electric
toothbrush after the vibration intensity is adjusted. According to the scheme provided by the invention, the gingival problem of the user can be accurately identified, and meanwhile, the gingival problem is quantified as the gingival red and swollen degree, so that the vibration intensity of the electric toothbrush is flexibly adjusted according to the gingival red and swollen degree and the reference adjustment information, and the experience feeling of the user is improved.
