Abstract

The invention provides a data enhancement method and device for a micro defect detection rate. The method comprises the following steps: acquiring a product image; preprocessing the product image to obtain a product image meeting a preset condition; acquiring defect type information of the processed product image; analyzing the defect type information of the product image to obtain the type information of the target defect; copying the target defect, and pasting the target defect at any position in the product image to complete data enhancement of the product image. The invention discloses a data enhancement method. The number of samples is increased by copying and pasting defect targets, the diversity of the samples randomly appearing in the images is increased on the premise that the authenticity of the samples is increased, the consistency of the sizes and the pixel density of the training images and the test images is reserved, and the detection rate of tiny defects of the mobile phone backboard is effectively increased.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a data enhancement method for detection rate of micro-defects, a data enhancement device for detection rate of micro-defects, a computer device and a non-transitory computer-readable storage medium. Background technique [0002] At present, industrial defect detection generally has the problem of few defect samples and a small proportion of defective pixels. In order to solve the above-mentioned difficulties that have existed in the industrial field for a long time, related technologies have proposed to increase the resolution of the input image or combine high-resolution features with low-resolution features. A technical solution for high-dimensional feature fusion in high-rate images. However, this approach of using higher resolutions increases computational overhead and does not address the imbalance between large and small objects. Contents of the invention...
