US 2025/0180489 A1 · METHOD AND DEVICE FOR INSPECTING HOT GLASS CONTAINERS WITH A VIEW TO IDENTIFYING DEFECTS

Abstract

There is provided a method for inspecting still hot glass containers. The method includes, for each container, acquiring at least one transmission image of the container illuminated by a source of a light passing through the container and at least one infrared radiation image of the container. The method also includes analyzing at least one transmission image and at least one infrared radiation image and ensuring a matching of at least part of the transmission image and at least part of the infrared radiation image. The method also includes classifying the container, from at least one transmission image and at least one infrared radiation image, matched with each other, in order to identify, for a container, at least one type of defect.

Dependent claims

A method for inspecting still hot glass containers exiting a manufacturing facility, for identifying, for a container, a type of one or more defects, the method comprising:

for each container,
acquiring at least one transmission image (It) of the container illuminated by a source of a light passing through the container and at least one infrared radiation image (Ir) of the container,
analyzing said at least one transmission image and said at least one infrared radiation image,
ensuring a matching of at least part of the transmission image and at least part of the infrared radiation image,
classifying the container, from said at least one transmission image and said at least one infrared radiation image, matched with each other, in order to identify, at least one type of defects.
