Abstract

The invention relates to an intaglio roller surface defect detection method and device and a storage medium. The method comprises the following steps that a to-be-detected intaglio roller is obtained; the gravure plate roller is driven to rotate, multi-layer scanning is conducted in the surface height direction of the gravure plate roller in the rotating process of the gravure plate roller, and a three-dimensional image of the surface of the gravure plate roller is obtained; and carrying out ink cell identification in the three-dimensional image, and obtaining net shape and ink cell depth information according to the identified ink cell so as to carry out defect point detection. Compared with the prior art, the method has the advantages that the printing roller does not need to be subjected to trial printing, defect detection is directly carried out on the surface of the printing roller, cost waste caused by trial printing is avoided, comprehensive and accurate defect detection on the surface of the printing roller is achieved, and the defect detection efficiency is improved.
