Automatic detection device and method of plane figure color shading

Abstract

The invention relates to an automatic detection device of plane figure color shading based on machine vision technology. The automatic detection device of the plane figure color shading comprises a camera, a memorizer, a displayer and a processor. The camera shoots a plurality of plane figures on work pieces. The processor stores images shot by the camera in the memorizer. The processor establishes a first classification and a comparison standard. A deviation value is obtained by comparing an image shot for the K+1th time with the comparison standard. The deviation value is judged whether exceeding an allowed error range value or not. When the deviation value is in the allowed error range value, the image shot for the K+1 time are classified as the first classification. When the deviation value is beyond the allowed error range value, a second classification and a comparison standard are established. The displayer displays each classification result obtained. The automatic detection device of the plane figure color shading based on the machine vision technology can automatically detect the color shading and classify the color shading. The invention further relates to an automatic detection method of the plane figure color shading.

Description

[0001] technical field [0002] The invention relates to an automatic detection device and method for plane graphic color difference based on machine vision technology. [0003] Background technique [0004] With the improvement of people's living standards, furniture and hotel decoration equipment are becoming more and more diversified, such as being made of materials such as ceramics, plastics, and wood, and the types of patterns and colors are also increasing. For example, with more and more colors, patterns and patterns of tiles, the surface color of tiles becomes more and more complicated. the [0005] At present, major tile factories manually group and number tiles according to the degree of color difference. However, due to the fatigue of the human eye and the interference of various factors (such as light, mental state, etc.), misjudgments and misjudgments are prone to occur, resulting in Inaccurate color separation and low production efficiency.
