ABSTRACT:
A glass defect detection system comprising an apparatus and methods for the real-time inspection for defects in and on transparent sheets, such as a large sheets of glass is disclosed. The defect detection system utilizes a plurality of dark-field illumination systems and bright-field illumination systems and a plurality of baffles. A plurality of imaging devices are deployed to obtain images of transparent sheets. The defect detection system provides uniform lighting capable of equal detection of defects in all orientations and geometries. An image processing system analyzes for defects in and on the transparent sheet.
