AI Technical Summary

Technical Problem

Existing machine vision inspection methods suffer from low quality inspection accuracy in circuit breaker production because defect features are overwhelmed by good product signals, and workpiece positioning deviations cause inspection failures, making it impossible to effectively identify defects at critical quality points.

Method used

A process feature dictionary model library is constructed. By employing a local gradient feature dictionary and hierarchical anchoring technology, the total energy function of the system is optimized through the calculation of local gradient feature vectors and spatial smoothing energy functions, thereby achieving accurate localization of key feature regions and defect identification.

Benefits of technology

It significantly improves the accuracy and robustness of defect detection, enables automated decision-making and workstation locking, and enhances the quality control level of circuit breaker production.
