This invention discloses a method and apparatus for sorting and grading cold-rolled strip steel based on a gray-level co-occurrence matrix and a decision tree, relating to the fields of metallurgical machinery and automation technology. It includes: acquiring image data and text data of the surface of the cold-rolled strip steel to be graded; inputting the image data and text data into a pre-constructed surface quality sorting and grading model for cold-rolled strip steel; and obtaining the surface quality sorting and grading result of the cold-rolled strip steel based on the image data, text data, and the surface quality sorting and grading model. This invention enables better intelligent judgment of the surface quality of cold-rolled strip steel, improves the accuracy of surface quality judgment, and makes the judgment system results more relevant to quality inspectors.
