Laser visualization processing method and system

The invention discloses a laser visualization processing method and system. The processing method comprises the steps that a product coordinate system, an image coordinate system and a drawing file coordinate system are established correspondingly; a to-be-processed graph is drawn on a drawing software interface of an industrial personal computer; an image of a product under the product coordinatesystem is acquired through a camera; according to the mapping relation between the coordinate systems, the product coordinate system is converted to the drawing file coordinate system, and an image of the product under the drawing file coordinate system is obtained; the product is processed according to the to-be-processed graph on the drawing file coordinate system, meanwhile, a processing planeis photographed through the camera, an image of the product in the processing process is obtained in real time, and the image is updated to the drawing file coordinate system in real time; and the graph on the drawing file is
