AI Technical Summary
Technical Problem
Existing technologies for conveyor belt speed measurement and positioning suffer from problems such as environmental corrosion, wear, and decreased accuracy. Pre-embedding RFID tags increases costs and limits flexible applications.
Method used
X-ray image recognition of conveyor belt joints is used. By training a model to identify the joint number and location, combined with defect detection, non-contact speed measurement and positioning can be achieved.
Benefits of technology
It achieves wear-free and accurate defect detection and speed measurement, overcomes the influence of special environments, and improves speed measurement accuracy and system stability.

Abstract
The present application relates to the field of image detection. Disclosed are an X-ray image-based defect detection and positioning method and apparatus, a device and a storage medium. The method comprises: acquiring X-ray images of a conveyor belt by means of an X-ray line-scan camera, and, on the basis of the X-ray images, training a conveyor belt splice detection model and performing target detection; upon recognition of a conveyor belt splice in an X-ray image, and on the basis of a splice image, determining the serial number of a target splice and position coordinates thereof on the conveyor belt; and upon detection of a target defect on the conveyor belt, and on the basis of the position coordinates of the target splice and a time interval between the target defect and the target splice, positioning coordinates of said defect on the conveyor belt. The present solution detects conveyor belt splices by means of X-ray, and uses the splices to divide conveyor belt sections, and when defect points are detected, defect positioning is realized on the basis of distance values of the defect points in the splice sections, thereby achieving non-contact and wear-free defect detection, speed measurement and positioning.
