Abstract
A machine vision-based sheet defect labeling method and apparatus, a device and a medium are provided. The method includes: performing a defect inspection on a target sheet conveyed to a preset defect inspection position, specifically, the target sheet continues to be conveyed towards a preset labeling position after passing the preset defect inspection position by being conveyed; generating a defect label of the target sheet when a defect present in the target sheet is determined, specifically, the defect label carries defect information represented by a two-dimensional barcode symbol including discontinuous dots; and labeling the defect of the target sheet at the preset labeling position with the defect label of the target sheet.
