IDENTIFYING DEFECTS IN TRANSPARENT CONTAINERS
First Claim
1. A system that is configured to detect a defect in a transparent container, the system comprising:
- an emitter that directs a color gradient through a sidewall of the transparent container, wherein color of light passing through the sidewall of the transparent container varies across the sidewall of the transparent container;
a camera that is configured to capture an image of the sidewall of the transparent container while the color gradient is directed through the sidewall of the transparent container; and
a computing system that is in communication with the camera, the computing system is configured to receive the image, detect a defect in the transparent container based upon the image, and output an indication that the transparent container includes the defect based upon the image of the sidewall of the container.

Abstract
Described herein are various technologies related to inspecting transparent containers for both opaque and transparent defects. An emitter is configured to direct a color gradient through a sidewall of a transparent container, such that color of light that passes through the sidewall varies across the sidewall. A camera is configured to capture an image of the sidewall of the transparent container while the color gradient passes through the sidewall of the container. A computing system receives the image and determines whether the sidewall of the container includes either an opaque or a transparent defect based upon the image.

10. A method comprising:
-
emitting, by a backlight, a color gradient, such that the color gradient passes through a sidewall of a transparent container that is under inspection; while the color gradient passes through the sidewall of the container, capturing an image of the sidewall of the container; identifying a defect in the sidewall of the container based upon the image of the sidewall of the container; and responsive to identifying the defect, outputting an indication that the sidewall of the container includes the defect. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A container inspection system that is configured to inspect transparent containers, the container inspection system comprising:
-
means for directing a color gradient through a sidewall of a transparent container; means for generating an image of the sidewall of the container while the color gradient is directed through the sidewall of the container; and a computing system that is configured to receive the image, detect a defect in the sidewall of the container based upon the image, and output an indication that the sidewall of the container includes the defect. - View Dependent Claims (20)
