On-line detection system and method of tile color difference based on machine vision

Abstract

The invention discloses an on-line detection system and method for tile color difference based on machine vision, which belongs to the technical field of tile production, and includes a sealing device, a standard module, a coordination module, a detection module and a server; the sealing device is an isolated black box installed in a production line, The sealing device is equipped with an industrial camera and a multi-color light source, and the standard module is used to simulate the collected images of standard tiles in the sealing device to obtain images of standard tiles; the present invention realizes rapid sorting and classification of tiles, reducing the Artificial, avoiding the uncertainty and waste caused by various human factors, improving production efficiency, ensuring the consistency and stability of product quality, making it possible to realize fully automated production for the tile production line; by setting the reuse module , Realize the reuse of tiles that do not meet the original design standards, re-open a color number of tiles, avoid waste of resources, and greatly increase economic benefits for manufacturers.

Description

technical field [0001] The invention belongs to the technical field of ceramic tile production, in particular to an on-line detection system and method for color difference of ceramic tiles based on machine vision. Background technique [0002] In the ceramic tile production process, due to its many production processes, long production process, and many and complex factors affecting product quality, the most important thing is that the product is fired at high temperature, and the complex physical and chemical changes are presented in this process. Various design colors, in this process, due to the stability and consistency of materials, the accuracy of the execution of each process, the stability of kiln firing, etc., will cause some inevitable color changes in tile products. Changes and differences; if these color differences are not classified, the consistency requirements of product quality cannot be met. Therefore, the current solution to this problem is to manually s...

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
