Abstract

The embodiment of the invention discloses a portable surface defect integrated detection device and a surface defect automatic detection method, and belongs to the technical field of surface defect detection. The device comprises a mechanical supporting and fixing unit, a control unit, an image acquisition unit, a lighting unit and an output unit. The method comprises a defect detection network model and a crack detection network model, and the defect detection network model is used for carrying out defect feature extraction, classification and defect marking on an image and outputting the image with a defect mark; the crack detection network model is used for carrying out crack feature extraction, classification and defect marking on the images and outputting the images with crack marks, the method can improve the detection effect of the surface defects with complex backgrounds and low gray contrast, and rapid and accurate detection of the surface defects and the surface crack defects is achieved.

Description

technical field [0001] The present application relates to the technical field of surface defect detection, in particular to a portable integrated detection device for surface defects and an automatic detection method for surface defects. Background technique [0002] During the production process of industrial products, due to the limitations of the production environment and production process, the surface will have quality problems of varying degrees. Surface defects are the most common quality problems, such as surface damage, cracks, Defects such as scratches are the main factors causing product failure. If the products with surface defects cannot be inspected and eliminated in time, there will be great safety hazards in the subsequent use process, and even lead to dangerous and destructive accidents, resulting in huge economic loss. Because of this, each product needs to be tested quickly with high precision before leaving the factory, so as to ensure that all products...
