Abstract

The invention discloses a cylindrical pot surface defect detection method, which comprises the following steps of: fixing a product to be detected on a rotating device, and enabling a detection surface of the product to be detected to be positioned on a focal plane of an area-array camera to synchronously rotate along with the rotating device; driving coaxial light source equipment to provide illumination for the to-be-detected product; driving the area-array camera to carry out image acquisition on the surface of the to-be-detected product to generate a target image; driving the industrial personal computer to recognize the target image so as to extract feature information of the target image; and driving the industrial personal computer to carry out dimension reduction and classification processing on the feature information so as to identify the defects of the to-be-detected product. The invention further discloses a controller, an industrial personal computer and a cylindrical pot surface defect detection system. By adopting the method, the classification of the surface defects of the high-brightness reflective metal cylindrical pot can be accurately completed.

Description

technical field

[0001] The invention relates to the technical field of metal surface defect detection, in particular to a cylindrical pot surface defect detection method, a controller, an industrial computer and a cylindrical pot surface defect detection system. Background technique

[0002] Pot-type kitchen utensils need to be polished and sanded to keep the surface beautiful and durable. In the production process, the irregular polishing operation is prone to defects such as scratches, concave deflation, wavy wrinkles, etc., and the sanding process can easily lead to dragging. The appearance of surface defects such as flowers, wrinkled bottoms, and browning. In the current production process, the surface defect detection of cookware is generally completed by manual visual inspection. The detection efficiency is low, and it is easily affected by subjective factors and missed inspections. It is no longer suitable for the small batch and customized production of products in t...
