Abstract
A method for identifying defects in a web of material translating along a travel path is provided. The method includes receiving a first image from a first camera; receiving a second image from a second camera; identifying a candidate as a possible defect within the first image; determining a first x-y position of the candidate relative to the first image; identifying the candidate within the second image; and determining the candidate is a probable defect based on the first x-y position and a second x-y position of the candidate within the second image. The first x-y position and the second x-y position predict the candidate is located on the web of material within a margin-of-error.
Claims20
A method for identifying defects in a web of material, comprising:
- receiving a first image from a first camera;
- receiving a second image from a second camera;
- identifying a candidate as a possible defect within the first image including identifying a first deviation in opaqueness of a portion of the web of material within the first image;
- determining a first x-y position of the candidate relative to the first image;
- identifying the candidate within the second image based on a predicted x-y position relative to the second image and identifying a second deviation in opaqueness of the portion of the web of material within the second image;
- and
- determining the candidate is a probable defect based on the first x-y position and a second x-y position of the candidate within the second image, wherein the first x-y position and the second x-y position predict the candidate is located on the web of material within a margin-of-error.
A computing device for identifying defects in a web of material, the computing device comprising:
- a memory;
- and
- at least one processor configured for:
- receiving a first image from a first camera;
- receiving a second image from a second camera;
- identifying a candidate as a possible defect within the first image including identifying a first deviation in opaqueness of a portion of the web of material within the first image;
- determining a first x-y position of the candidate within the first image
- identifying the candidate within the second image based on a predicted x-y position relative to the second image and identifying a second deviation in opaqueness of the portion of the web of material within the second image;
- and
- determining the candidate is a probable defect based on the first x-y position and a second x-y position of the candidate within the second image.
A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium storing instructions to be implemented on at least one computing device including at least one processor, the instructions when executed by the at least one processor cause the at least one computing device to perform a method for identify defects in a web of material, the method comprising:
- receiving a first image from a first camera;
- receiving a second image from a second camera;
- identifying a candidate as a possible defect within the first image including identifying a first deviation in opaqueness of a portion of the web of material within the first image;
- determining a first x-y position of the candidate within the first image
- identifying the candidate within the second image based on a predicted x-y position relative to the second image and identifying a second deviation in opaqueness of the portion of the web of material within the second image;
- and
- determining the candidate is a probable defect based on the first x-y position and a second x-y position of the candidate within the second image.
