Abstract
A system for the automated analysis of image quality obtained by a camera in a camera tunnel system includes a test pattern on an item for placement in the camera tunnel system and an imaging subsystem configured to capture an image of the item using the camera tunnel system, wherein the image includes an image of the test pattern. The system further includes an image analysis tool configured to automatically identify and analyze the image of the test pattern for generating one or more image quality metrics.
Claims43
A system for the automated analysis of image quality obtained by at least one camera in a camera tunnel system, comprising:
- a test pattern on an item for placement in the camera tunnel system;
- an imaging subsystem configured to capture an image of the item using the camera tunnel system, wherein the image includes an image of the test pattern;
- and
- an image analysis tool configured to:
- automatically identify the image of the test pattern;
- and
- automatically analyze the image of the test pattern and generate and display one or more image quality metrics.
A method for the automated analysis of image quality obtained by at least one camera in a camera tunnel system, comprising:
- a test pattern on an item for placement in the camera tunnel system;
- capturing an image of the item using the camera tunnel system, wherein the image includes an image of the test pattern;
- identifying the image of the test pattern automatically;
- and
- automatically analyzing the image of the test pattern and generating and displaying one or more image quality metrics.
A system for the automated analysis of image quality obtained by at least one camera in a camera tunnel system, comprising:
- a test pattern on an item for placement in the camera tunnel system;
- an imaging subsystem configured to capture an image of the item using the camera tunnel system, wherein the image includes an image of the test pattern;
- and
- an image analysis tool configured to:
- automatically identify the image of the test pattern;
- automatically analyze the image of the test pattern for generating one or more image quality metrics;
- and
- generate a printable version of the test pattern.
A system for the automated analysis of image quality obtained by at least one camera in a camera tunnel system, comprising:
- a test pattern on an item for placement in the camera tunnel system, said test pattern comprising a central contrast area having adjacently disposed dark and light areas defining a central location where the dark and light areas meet;
- an imaging subsystem configured to capture an image of the item using the camera tunnel system, wherein the image includes an image of the test pattern;
- and
- an image analysis tool configured to:
- automatically identify the image of the test pattern;
- and
- automatically analyze the image of the test pattern for generating one or more image quality metrics.
