Abstract

The invention discloses a product surface defect detection method in an industrial scene, and relates to the technical field of product surface defect detection and machine vision in the industrial scene, the method comprises the following steps: step 1, image acquisition: acquiring a surface image of a product on an industrial assembly line; step 2, image labeling: performing defect labeling on the surface image to obtain a surface defect data set; step 3, data enhancement: the surface defect data set is subjected to data enhancement, the data enhancement is a combination of one or more of the following data enhancement modes, and the data enhancement modes comprise random cutting, random horizontal overturning, random vertical overturning, scale jitter, color jitter, Mosaic or Mixup; 4, constructing a surface defect detection model; 5, training a surface defect detection model; and step 6, predicting the surface defect detection model.

Description

technical field [0001] The invention relates to the technical field of product surface defect detection and machine vision in an industrial scene, and in particular to a product surface defect detection method in an industrial scene. Background technique [0002] In industrial scenarios, efficient and stable quality inspection is an important part of the product manufacturing process. The speed and accuracy of quality inspection will directly affect the production capacity of the assembly line and the final quality of the product. Whether there is any defect on the surface of the product is an important basis to measure whether the product meets the requirements of industrial quality. In the process of industrial production and manufacturing, the detection of defects on the surface of products is mostly done through manual quality inspection, but manual detection methods require high labor costs, and there are high false detection rates and missed detection rates, which can...
