Intelligent online detection and automatic grading method and system for pottery tiles

The invention discloses an intelligent online detection and automatic grading method and system for pottery tiles. The method comprises the steps of acquiring image data of a to-be-detected pottery tile, respectively carrying out crack defect detection, unfilled corner defect detection, chromatic aberration defect detection, glaze lack defect detection and bulge defect detection on the image data,obtaining the grade of the to-be-detected pottery tile according to the defect detection results, respectively carrying out first pretreatment or second pretreatment on the acquired image according to the detection requirements, adopting different filtering and defect extraction modes at the same time, carrying out color discrimination during glaze lack detection in particular, and carrying out image pretreatment, image segmentation, feature extraction and corresponding defect grades on to-be-detected pottery tiles with different colors by adopting different algorithms, so that the detectionof various defects can be
