| Abstract: | A measuring method of the surface defects for the large model of the monitor tube, by scanning with planar CCD array is presented. And the connective method for images of detection with the software and using the theory of subdivision for the gray value has the advantages of the experimental result. The resolution is 0.05mm. |
