Abstract
This paper makes a proposal regarding a new construction of automatic visual inspection system for web-shape products. The inspection process is divided into “detection” and “investigation” stages aim to imitate a retina function of human vision. LCI-method, developed by author as a new defect inspection method, is introduced to the detection process. LCI simulates “Peripheral Visual Inspection”, recently have been quite effective for various production fields. Then 3D measurement of defect shape by using Quasi-phase-shift method is adapted for the investigation process. This separated inspection system makes it possible to improve the sensitivity of defect detection and reduce the number of imaging equipment.
