Abstract

A bathroom ceramic surface defect detection method comprises the following steps: collecting an original image of bathroom ceramic, and constructing a bathroom ceramic surface defect image data set; expanding bathroom ceramic surface defect images, and then making all the bathroom ceramic surface defect images into a bathroom ceramic surface defect data set; constructing an improved Center Net defect detection model by utilizing a Tensorflow and Keras open source deep learning framework; inputting bathroom ceramic defect images into the improved Center Net defect detection model in batches, and iteratively training the model to finally obtain a bathroom ceramic surface defect detection model; after the training is completed, inputting a test set sample into the bathroom ceramic surface defect detection model, and verifying the robustness of the improved Center Net defect detection model; and inputting a bathroom ceramic surface defect image to be detected into the tested bathroom ceramic surface defect detection model, and carrying out defect detection. According to the invention, manual defect detection can be replaced, and the detection efficiency and the detection precision are obviously improved.

Description

technical field [0001] The invention relates to ceramic defect detection technology, in particular to a method for detecting surface defects of sanitary ceramics based on improved CenterNet. Background technique [0002] China is the world's largest producer and seller of sanitary ceramics. There are many manufacturers in the sanitary ceramics industry, and the degree of automation of the entire industry is steadily improving. However, the quality inspection of finished sanitary ceramics is far from enough, mainly relying on manual inspection by inspectors. The detection efficiency is low, and it is easily affected by the experience factors and physical condition of the test personnel. [0003] In recent years, with the development of computer technology, deep learning technology has also made great progress, and more and more enterprises have begun to use deep learning technology for defect detection. Compared with existing detection technologies, defect detection based on...
