Challenge & Solution
Stamped Sheet-Metal Surface Defect Detection
ChallengeDefects are as small as 0.3mm; manual visual inspection missed up to 2.8% of them, and defects that reach downstream stages significantly raise rework cost.
SolutionSpecialized optical imaging suppresses metal glare and enhances contrast; multi-angle, multi-spectral lighting combined with deep learning identifies micro-defects.
