A system for contactless color label identification and - review and method therefor

摘要

an optical monitoring system, the presence of defects in colored labels check, for example, the sidewalls of cylindrical beverage cans are mounted.the optical monitoring system uses a carrier for carrying the cans in a production line where such cans typically randomly oriented.the optical monitoring system to a optikkopf positioned near the cans, if you move in the production line.without physically intervene or interact with the movement.the optikkopf feels a predetermined number of colors in a predetermined field of view, each moving can appear.the randomly oriented cans of different parts of the label in the predetermined field of view is visible in its position.the optikkopf produces analog electrical signals corresponding to the intensity of each abgefu00fchlten color.a computer is used for the analog electrical signals from the optikkopf to process.the first computer creates a number of zweifarbsignaturen based on the selected number of colors.after enough doses of the optikkopf happen, with all zweifarbsignaturen are fully developed.does the computer the colors of each subsequent dose, and compares it with the generated farbsignatur. if the abgefu00fchlte choices in the generated farbsignaturen falls...
