The invention relates to a glass surface defect detection method, device and system and a computer readable storage medium. The method comprises the steps: acquiring a first glass surface image and asecond glass surface image of to-be-detected glass, wherein the first glass surface image and the second glass surface image are the same image; carrying out mean filtering on the first glass surfaceimage by adopting a first filtering template to obtain a first filtered image, and carrying out mean filtering on the second glass surface image by adopting a second filtering template to obtain a second filtered image, wherein the first filtering template and the second filtering template are different in size; extracting difference areas of the first filtering image and the second filtering image, wherein the difference areas are in one-to-one correspondence with the surface defects of the glass to be detected. According to the invention, the problem of low glass surface defect detection efficiency in related technologies is solved, and the glass surface defect detection efficiency is improved.
Description
technical field [0001] The present application relates to the field of glass detection, in particular to a glass surface defect detection method, device, system and computer-readable storage medium. Background technique [0002] Large glass is widely used in various design and application fields: such as household applications, architectural applications, decoration applications, transportation equipment applications, etc., large glass has a wide range of application fields. The traditional glass defect detection method can no longer meet the requirements of modern production, especially for the defect detection of large glass surface, there is an urgent need for an automatic and reliable glass surface defect detection technology. [0003] Glass surface defect detection usually collects glass surface images through a dedicated high-definition camera, and then performs grayscale, binarization, image enhancement, image area filling, edge enhancement, edge contour extraction, a...
