How to Detect Mask Defects
Using masks as an example, Wordop can detect defects in machine vision to detect features such as mask breathing valve, front/back distinction, dirt, hair, ear band length/offset, nose bar length/offset, etc.
Breathing valve - positive and negative differentiation test
Aluminum bars with or without testing
External contour inspection, stitch positioning inspection
Check if the ear band cord of the mask is properly pressed
