Embodiment Construction

[0051] In order to make the purpose, features and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described The embodiments are only some of the embodiments of the present disclosure, but not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present disclosure.

[0052]The disclosed classification and detection model includes a feature extraction network, a region of interest generation network, and an R-CNN classification and positioning network. The feature extraction network is a feature pyramid network, which not only avoids the loss of small feature information, but also complements and enhances flaw fea...

Abstract

A model establishing method and device for flaw detection, electronic equipment and a storage medium are applied to the technical field of detection, and the method comprises the steps of establishingan image set, wherein the image set comprises different types of flaws; building a defect detection network model based on the image set and a Faster RCNN; training the defect detection network modelto obtain a classification detection model; wherein the classification detection model is used for carrying out defect detection on a to-be-detected image and outputting the type, shape and positionof a defect in the to-be-detected image. The invention can be used for defect detection of extreme sizes.

Description

technical field [0001] The present disclosure relates to the technical field of image detection, and in particular to a model building method, device, electronic equipment and storage medium for flaw detection. Background technique [0002] In recent years, with the development of science and technology, the automation of product quality inspection has become one of the main trends in the development of modern production. Automated inspection of defects is of great significance to reduce labor, improve production efficiency, and promote industry intelligence. [0003] The traditional manual visual inspection method has problems such as low detection efficiency, slow detection speed, low detection accuracy, and inconsistent detection standards. Due to the long working hours of inspection, inspectors are prone to visual fatigue, not only the false detection rate and missed detection rate remain high, but also cause great damage to human eyes. Therefore, the defect detection m...
