Abstract

The invention provides a model training method and device. The model training method comprises the steps: acquiring multiple frames of training samples with labels, wherein the labels at least comprise a first label and a second label, and the first label is used for recording a marked first area in the training samples as an area prone to false detection, and the second label is used for recording a marked second area in the training samples as an area with defects; and training a detection model for detecting defects by utilizing the training samples with the labels and the position information of the first areas and the position information of the second areas in the training samples. By adding the labels of the areas prone to false detection, learning of features of the areas prone tofalse detection can be enhanced according to the added labels and positions of the areas prone to false detection when the model is trained, and the false detection rate of the detection model is reduced, and the detection accuracy of the detection model is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a model training method and device, and a defect detection method and device. Background technique [0002] In industrial production, it is necessary to perform defect detection (ASI, Automated Surface Inspection) on the produced products. For example, after the textile industry produces cloth, it is necessary to detect whether there are flaws or defects in the cloth, so as to facilitate timely repair and improve the quality of the cloth. Although there are many kinds of traditional defect detection methods, they either have poor detection results, or have a large amount of calculation and low efficiency. [0003] At present, the defect detection is carried out by using the neural network based on deep learning, but the false detection rate is relatively high. Contents of the invention [0004] In view of this, the present application provides a defect detection m...
