The invention relates to a chain type flue-cured tobacco grading method based on a cascade classifier. The method relates to the technical field of machine learning and flue-cured tobacco grading, according to flue-cured tobacco purchasing standards, samples are formulated, images are collected, a grading data set is established, the images of the grading data set are preprocessed by using OpenCV and a feature extraction algorithm, and features such as the shape and the color of a flue-cured tobacco preprocessing data set are extracted. And performing flue-cured tobacco chain type grading model parameter training by using the flue-cured tobacco preprocessing data set and the extracted features to obtain a flue-cured tobacco chain type grading model. Adjusting parameters of the flue-cured tobacco chain type grading model, completing reasoning deployment on flue-cured tobacco grading equipment, and obtaining a flue-cured tobacco grading result based on the flue-cured tobacco chain type grading model.
