According to characteristics of optical element surface defect
such as low contrast
fuzzy boundaries
and the existing automatic detection algorithm
propose a digital evaluation system based on machine vision technology
which solves the problems in automatic detection such as camera localization
image acquisition
defects detection
image mosaic and defects statistics during flaw image acquiring process. Experimental results show the system can realize the automatic detection of the precision optical element surface defect and distinguish the defects of micron level effectively
