Claim 7:
8. The method of claim 1, wherein the defect type comprises a pit defect and a protrusion defect, and the determining the segmented defect mask based on a predefined defect rule to output a defect detection result further comprises:
when the defect type of the defect region is a pit defect, if both the segmented 2D defect mask and the segmented 3D defect mask comprise the defect region, or the depth of the defect region is greater than a predefined threshold for the pit detect, outputting a detect class as the defect detection result; or
when the defect type of the defect region is a protrusion defect, if both the segmented 2D defect mask and the segmented 3D defect mask comprise the defect region, and the size and the depth of the defect region are greater than predefined thresholds for the protrusion defect, outputting a defect class as a defect detection result.
