Claims23
A system for inspecting a glass container comprising:
- a panel configured to illuminate the glass container, the panel including a first plurality of light sources directed parallel to one another;
- a first camera configured to image the illuminated glass container;
- a controller configured to adjust the amount of power supplied to each of the light sources individually;
- and
- a processor configured to evaluate the image of the illuminated glass container for indications of defects in the container.
A method of inspecting a glass container using a first panel including a first plurality of light sources, the method comprising:
- illuminating a first predetermined set of the first plurality of light sources to illuminate the glass container with a first predetermined illumination pattern;
- capturing a first image of the illuminated glass container;
- illuminating a second predetermined set of the first plurality of light sources to illuminate the glass container with a second predetermined illumination pattern, the second predetermined illumination pattern being different from the first predetermined illumination pattern;
- capturing a second image of the illuminated glass container;
- and
- evaluating the first and second images to determine whether the glass container includes a defect.
