This data “object” representation of the roll map is recorded, and then compared to predetermined product set-up parameters and machine vision hardware integrity data to determine the accuracy of the web inspection. The generated “certification” assures with a substantial degree of precision that the machine vision hardware is calibrated and operating correctly, and that the correct system setup parameters for the particular web product being inspected are being applied.Field of SearchBY MONITORING OF WEBS OR THREADFor flaws or imperfections INSPECTION OF FLAWS OR IMPURITIES Manufacturing or product inspection With circuit for evaluating a web, strand, strip, or sheet With indication of presence of material or feature Flaw or defect detection Radiant energy (e.g., X-ray, infrared, laser) Quality evaluation TESTING SYSTEM Performance or efficiency evaluation History logging or time stamping Remote supervisory monitoring | |
