Method and system for positioning and measuring defects of glass blocks

The invention discloses a positioning and measuring method and system for defects of a glass block material, and relates to the technical field of glass quality detection.The method comprises the steps that the glass block material to be detected is horizontally placed in a detection area, a lamp bead of a first illumination light source is lightened in sequence, a first collecting system shoots a first image, a second image is shot after a second illumination light source is turned on, and the second image is obtained; scanning the whole to-be-detected glass block material, and recording each defect point and the corresponding xyz coordinate; sequentially inputting the coordinates of all the defect points into a second acquisition system, turning off the first illumination light source and the second illumination light source, turning on the third illumination light source, sequentially moving the second acquisition system to the corresponding positions of the defect points for shooting, shooting an image fo
