Abstract

The present invention provides a method for identifying coating surface defects based on deep learning, comprising the following steps: S1: selecting a feature extraction network; S2: designing an inverted pyramid classifier; S3: constructing a recognition model; S4: using training after optimization and adjustment The method trains the recognition model; S5: recognizes the surface defects of the coating. The invention provides a coating surface defect identification method based on deep learning, which can realize fast and high-precision identification of coating surface defects in the case of small samples, and has a good application prospect in the field of automatic detection and identification of coating surface defects .

Description

technical field [0001] The invention belongs to the fields of surface defect identification and deep learning, in particular to a coating surface defect identification method based on deep learning. Background technique [0002] Coating is a layer formed on the surface of a metal or non-metal substrate with a certain thickness, which is different from the substrate material and has a certain strengthening, protection or special function. It has been widely used in modern machinery and equipment. However, in the actual spraying and use process, the coating is prone to various defects, such as sagging, orange peel, exposed bottom, cracks, etc., which greatly reduces the overall protective performance of the coating, shortens the service life, and further affects the coating. Layer using the device has an impact. [0003] The previous methods of detecting and identifying coating surface defects relying on human eyes are difficult to meet the precision and speed requirements of...
