Abstract

The paper presents a solution for inspection of contact lens based on machine vision. Being characterized by a high degree of automation the proposed system satisfies the current manufacturing requirements that require short times to obtain the final product. The machine vision system(MVS) proposed integrates two classic systems used in the inspection process: a profile projector and a system for image acquisition and processing. For validating the results, three contact lenses from the same batch were inspected generating the possibility to identify possible defects or technological errors from manufacturing process. Evaluated parameters were the lens diameter(LD), front optical radius(FOR) and the front peripheral radius(FPR) of the lens. The study presents a series of important conclusions about the possibility of integrating vision systems(VS) in the contact lens inspection process, as well as the performance of the proposed system.
