In assessing the performance of micro-capacitor defect detection, we considered several metrics: Precision: This is the product of the number of successfully discovered defects, or true positive detections (TP), and the total number of false positives (FP), or occurrences of false positives that were mistakenly labeled as defects.
The critical technology of capacitive polarity recognition is the polarity detection algorithm with the image. Because the pin configuration of the capacitor dictates that polarity detection of capacitor is a multi-classification problem, machine learning is an effective method for this application.
Integrated algorithmic enhancement and performance efficiency: The deployment of YOLOv8 for detecting defects in micro-capacitors was notably advanced by integrating the SimAM attention mechanism with the BiFPN architecture. This combination significantly improved the model's precision in identifying small defects amidst complex visual backgrounds.
To address these challenges, this paper proposes an innovative approach employing an enhanced 'you only look once' version 8 (YOLOv8) architecture specifically tailored for the intricate task of micro-capacitor defect inspection.
A micro-capacitor surface defect (MCSD) dataset comprising 1358 images representing four distinct types of micro-capacitor defects was constructed. The experimental results showed that our approach achieved 95.8% effectiveness in the mean average precision (mAP) at a threshold of 0.5.
