Rolling surface defect detection system and method

The invention relates to the field of rolling surface defect detection, in particular to a rolling surface defect detection system and method. The rolling surface defect detection system comprises a control device, a light source generation device, a galvanometer and an identification device, wherein the galvanometer is arranged on a light path between the light source generation device and a rolling surface to be detected; the light source generating device, the galvanometer and the recognition device are all in communication connection with the control device; light beams emitted by the light source generating device are projected to the rolling surface to be measured through scanning of the galvanometer to form stripes; the control device adjusts driving signals of the galvanometer to adjust the positions of the stripes projected to the rolling surface to be measured; and the identification device shoots the rolling surface to be detected to obtain multiple target images and detectsthe defects of the rolli
