Anti-dazzle circular daily ceramic device applique out-of-bound detection method

Abstract

The invention discloses an anti-dazzle circular daily ceramic device applique out-of-bound detection method. The method comprises the steps of: first, obtaining a dazzle-free original ceramic grayscale image in the low-light condition through a camera; second, obtaining a grayscale enhanced image which is apparent in contrast; third, obtaining a binary image through a threshold segmentation technology; fourth, filling the outermost boundary inner area; fifth, obtaining a second outer boundary with probable out-of-bound patterns through an image residual error technology; sixth, filling the inner area of the second outer boundary and obtaining the contour of the second outer boundary through a boundary extraction operator; seventh, determining the center of the circular ceramic device and drawing a radius curve, a radius residual error curve and a radius residual error power exponent curve; eighth, positioning the out-of-bond patterns and measuring the dimension. The method is efficient and convenient, simple and convenient to operate and provided with broad market prospects.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a decal out-of-bounds detection method for an anti-glare round ceramic device for daily use. Background technique [0002] As a traditional industry, the production process of ceramic utensils has the characteristics of low toughness, special production technology, and difficult quality control during batch production. In order to improve the yield rate of products and enhance the competitiveness of enterprises, most manufacturers will set up product quality inspection departments. However, the detection of defects in daily-use ceramics in most enterprises still remains at the level of manual naked eye detection. The detection efficiency is low, the labor intensity is high, the product quality is unstable, and the high missed detection rate has become a major criticism. [0003] At present, with the advancement of industrial modernization, the detection technology based...

However, the detection of defects in daily-use ceramics in most enterprises still remains at the level of manual inspection with naked eyes. The detection efficiency is low, the labor intensity is high, the product quality is unstable, and the missed detection rate is high, which has become a major criticism.

[0003] At present, with the advancement of industrial modernization, the detection technology based on machine vision has been widely used in various fields, but the popularity in the traditional ceramic industry is far from enough, and the only equipment is concentrated on high-precision engineering ceramics , intelligent testing equipment for daily-use ceramics is almost in a blank state

One of the important reasons that restricts the promotion of computer vision technology in the daily-use ceramics industry is that there is glare on the ceramic surface, which is not easy for computer vision equipment to collect images, that is, the ceramic surface will be glare under the light, covering the details of the ceramic surface, directly affecting the later stage.
