AI Technical Summary

Technical Problem

In the current technology for inspecting the quality of profile cross sections, manual inspection is inefficient, visual recognition accuracy is greatly affected by image quality, burrs affect the accuracy of dimensional measurement, and two-dimensional imaging cannot accurately locate the position, resulting in large deviations in measurement results.

Method used

By employing point cloud data processing and generative adversarial networks, and through point cloud registration, segmentation, and burr synthesis detection models, the influence of burrs is identified and eliminated. The burr synthesis detection model is trained using generators and discriminators to generate realistic burr masks. Combined with a burr size recognition model, the detection accuracy is improved.

Abstract

This invention belongs to the field of cross-section inspection and provides a method, system, medium, and device for detecting the cross-section dimensions of profiles. The method includes separating and projecting the point cloud data of the profile cross-section; processing the profile cross-section image using a pre-trained virtual burr synthesis detection model to identify whether burrs exist in the image; if no burrs are found, the profile cross-section dimensions are directly obtained; if burrs are found, the burr size is detected and compared with a set burr size threshold. Based on the comparison result, it is determined whether to remove point cloud data from the profile cross-section to a set distance to re-inspect the updated profile cross-section image for burrs, until no burrs are found or the burr size is less than the set burr size threshold, ultimately obtaining the profile cross-section dimension detection result. This method can detect burrs on the cross-section point cloud data of profiles, improving the accuracy of the profile cross-section dimension detection results.
