Texture surface defect detection and segmentation device and method in industrial environment

Abstract

The invention relates to a texture surface defect detection and segmentation device and method in an industrial environment, and belongs to the technical field of industrial texture surface defect detection and segmentation. The device comprises an input module I, a feature extraction module II, a defect region extraction module III, a defect region alignment module IV, a detection module V and asegmentation module VI; the input module I outputs to the feature extraction module II; the feature extraction module II outputs to the defect region extraction module III and the defect region alignment module IV, the defect region extraction module III outputs to the defect region alignment module IV, and the defect region alignment module IV outputs to the detection module V and the segmentation module VI. The specific types, accurate position coordinates and spatial distribution information of multiple types of defects can be automatically obtained, and the method has good robustness for the multi-scale of the defects. The method has wide applicability and relatively high detection precision for texture surface defects.

Description

technical field [0001] The invention relates to a texture surface defect detection and segmentation device and method in an industrial environment, belonging to the technical field of industrial texture surface defect detection and segmentation. Background technique [0002] In the process of industrial product processing, due to raw materials, rolling equipment and technology, it is inevitable that different types of defects will appear on the surface. Common defects include scratches, pores and inclusions, etc. These defects not only affect the appearance of the product , It will also reduce the corrosion resistance, wear resistance and fatigue strength of the product, causing huge economic losses to the enterprise. How to automatically detect and segment surface defects in the production process to control and improve product quality has always been a matter of great concern to enterprises. [0003] Traditional detection methods use morphology, local ring comparison, sal...
