Integrating a machine vision system for cosmetic inspection of optical parts

Open Access Open Access

Abstract

A multistation inspection center has been built that performs cosmetic inspection of small lenses. The system design considerations and tradeoffs involved in constructing the system are discussed. Included are such issues as central vs distributed image processing, speed, and cost. Of particular importance are issues of defining and characterizing cosmetic defects on a machine vision system that correlates with visual grading. A distributed processing system with a central controller was developed. It provides characterization of nine different defects including scratches, pits, haze, dimples, and several other defects relating to the method of manufacture.
