Abstract: A method for detecting and classifying defects in high-throughput transparent articles such as syringes, vials, cartridges, ampules, and bottles is provided. The method includes the steps of providing a stream of the articles; capturing a first digital image of each of the articles in the stream; inspecting the first digital image for objects; determining parameters of the objects; performing a first classification step to classify the objects into a first defect class and a second defect class; performing a second classification step to classify the objects into a plurality of defect types using at least two second classification models; comparing at least one object parameter of a classified object with a predetermined defect type dependent threshold; classifying the article as defective or non-defective based on the comparing step; and separating defective articles from non-defective articles.

Abstract: Apparatuses and methods for inspecting a pharmaceutical cylindrical containers are provided. The apparatus includes a support device, a light emitting unit, and a light receiving unit. The support device supports the pharmaceutical cylindrical container and rotates the cylindrical pharmaceutical container around a longitudinal axis. The light emitting unit has a light source that illuminates the pharmaceutical cylindrical container with a detection beam while the support device rotates the pharmaceutical cylindrical container. The light receiving unit has a camera that acquires polarization information of the detection beam.
