Abstract

The invention provides a coating surface defect identification method based on deep learning. The method comprises the following steps: S1, selecting a feature extraction network; s2, designing an inverted pyramid type classifier; s3, constructing an identification model; s4, training the recognition model by using the optimized and adjusted training method; and S5, identifying the surface defects of the coating. According to the coating surface defect identification method based on deep learning provided by the invention, rapid and high-precision identification of the coating surface defect can be realized under the condition of a small sample, and the method has a relatively good application prospect in the field of automatic detection and identification of the coating surface defect.

Description

technical field [0001] The invention belongs to the field of surface defect recognition and deep learning, in particular to a method for recognizing coating surface defects based on deep learning. Background technique [0002] Coating is a covering layer with a certain thickness formed on the surface of metal or non-metal substrate, which is different from the substrate material and has certain reinforcement, protection or special functions. It is widely used in modern mechanical equipment. However, in the process of actual spraying and use, the coating is prone to various defects, such as sagging, orange peel, exposed bottom, cracking, etc., which greatly reduces the overall protective performance of the coating and shortens the service life. Layers use devices to effect. [0003] In the past, the method of detecting and identifying coating surface defects by human eyes was difficult to meet the precision and speed requirements of industrial production due to high cost, lo...
