Abstract

The invention provides a bearing appearance defect detection system. The detection system comprises: an image acquisition module which obtains an infrared polarization image and an infrared light intensity image of a bearing image to be detected; an image denoising module which denoises the infrared polarization image and the infrared intensity image respectively, an image fusion module which fuses the denoised infrared polarization image and the infrared light intensity image to obtain the fusion image of the bearing to be detected, a bearing appearance feature extraction module which extracts the appearance feature information of the bearing to be detected from the fusion image, and obtains the appearance feature vector of the bearing to be detected; and a bearing appearance defect recognition module which judges whether the bearing to be inspected has the appearance defect or not according to the appearance feature vector of the bearing to be inspected and the standard appearance feature vector of the corresponding bearing stored in advance. The invention realizes the intelligentization of the bearing appearance defect detection, improves the defect recognition rate, the removalrate of the unqualified bearing product, and also improves the overall quality of the factory product.

Description

technical field [0001] The invention relates to the technical field of bearing detection, in particular to a bearing appearance defect detection system. Background technique [0002] During the bearing production process, there will be a small amount of defects such as corrosion and scratches on the outer surface of the bearings, which will become waste products and defective products. These waste products and defective products must be identified and removed before leaving the factory. Traditional bearing surface defect detection is mainly carried out manually. Manual detection is prone to false detection and missed detection. It is not only inefficient, lacks accuracy and standardization, but also cannot classify the detection data and send it to the computer for quality management in real time. Contents of the invention [0003] In view of the above problems, the present invention provides a bearing appearance defect detection system. [0004] The object of the present...
