AI Technical Summary

Technical Problem

In the context of high-speed train operation, traditional defect detection solutions are difficult to accurately locate defects and cannot provide a reliable benchmark for subsequent identification. Especially when trains are running at high intensity, the wear and aging of parts are accelerated, which can easily lead to failures and safety threats.

Method used

By determining the target detection box and standard box in the test image and the standard image, a target optical flow field is generated. Based on the optical flow field, the registration result between the standard box and the target detection box is determined, thus achieving component matching.

Benefits of technology

It achieves accurate matching of components in test images, reduces the omission of defect detection, and provides a reliable benchmark for subsequent defect detection.

Abstract

A registration result determination method and device, electronic equipment, storage medium and program product are disclosed. Specific embodiments include: determining a test image and at least one target detection frame corresponding to the test image; determining a standard image and at least one standard frame corresponding to the standard image; generating a target optical flow field based on the standard image and the test image; and determining a registration result between each standard frame and the corresponding target detection frame according to the target optical flow field. Through the target optical flow field between the standard image and the test image, the registration of the standard frame and the target detection frame is achieved, the accurate component matching of the test image is completed, the omission of the component to be detected in the test image during defect detection is reduced, and the registration result between each standard frame and the corresponding target detection frame provides a reliable reference for subsequent defect detection.
