Ceramic tile color difference online detection system and method based on machine vision

Abstract

The invention discloses a ceramic tile color difference online detection system and method based on machine vision, and belongs to the technical field of ceramic tile production. The system comprises a sealing device, a standard module, a coordination module, a detection module and a server; the sealing device is an isolation camera obscura body installed in a production line, an industrial camera and a multicolor light source are arranged in the sealing device, and the standard module is used for simulating an acquired image of a standard ceramic tile in the sealing device to obtain a standard ceramic tile image; according to the ceramic tile sorting and classifying device, quick sorting and classifying of ceramic tiles are achieved, manpower is reduced, uncertainty and waste caused by various human factors are avoided, the production efficiency is improved, the consistency and stability of product quality are guaranteed, and full-automatic production of a ceramic tile production line becomes possible; and by arranging the reutilization module, tiles which do not meet the original design standard are reutilized, tiles with one color number are rearranged, waste of resources is avoided, and economic benefits are greatly improved for manufacturers.

Description

technical field [0001] The invention belongs to the technical field of ceramic tile production, in particular to a system and method for on-line detection of tile color difference based on machine vision. Background technique [0002] In the ceramic tile production process, due to its many production processes and long production process, there are many and complicated factors affecting product quality. Various design colors, in this process, due to the stability and consistency of materials, the accuracy of each process, the stability of kiln firing, etc., will cause some inevitable color changes in ceramic tile products. Changes and differences; if these color differences are not classified, the consistency requirements of product quality cannot be met. Therefore, the way to solve this problem is to manually sort the color numbers at present. [0003] In the production of tiles, except for grading, the production automation of other pre-processes is relatively high. The ...

AI Technical Summary

Problems solved by technology

[0003] In ceramic tile production, except for grading, the production automation of other previous processes is relatively high. The production speed on the assembly line is 25m / min or above, and the output is large and the speed is fast. As the final color separation and grading process, it is currently manual To sort the color number of finished tiles, the production factory requires a lot of labor, high labor intensity and low efficiency, and because it is manual sorting, it is affected by individual visual judgment, human eye fatigue, human physiology, mood and other factors. The color separation error of the tiles is relatively large, and the consistency and stability of the final product are relatively poor
